Pay by Mobile Casinos

Pay by mobile is a simple way of depositing at online casinos without having to enter any of your bank details. With pay by mobile services your deposits will either be charged to your monthly phone bill or taken from your Pay-As-You-Go (PAYG) balance. All you need is a UK phone number and you’re good to go!

This page will cover all you need to know about pay by mobile casinos. We’ll go through what pay by mobile services are available, how they work, and which online casinos offer them. We will also provide information on how to use pay by mobile services to access online casino bonuses, and suggest some alternatives if either pay by mobile doesn’t interest you, or isn’t accepted by your chosen online casino.

Pay by Mobile Casinos Explained

The main benefits of this payment method is that it doesn’t require you to enter any of your bank details – making it highly secure – and is available to anyone who has a phone number.

You simply choose a pay by mobile service at your online casino’s payment section, enter your phone number and the amount you would like to deposit, and then confirm the transaction via the text message that will have been sent to your mobile. If you have a pay monthly contract, the deposit will be added to your monthly bill, and if you are a PAYG customer the money will be deducted from your credit.

The only downsides are that you usually can’t withdraw your cash using pay by mobile services, so you’ll need to have another payment method lined up. Also, per European legislation, there are both daily and monthly limits on how much you can spend with this method. Some pay by mobile services, such as PayViaPhone, also charge small transaction fees. But if you like to keep your payments small, simple and safe, there are few better options than UK pay by mobile casinos.

How Do Pay by Phone Casinos Work?



The way that pay by phone casino billing works is that the payment provider will charge your stored debit card, or payment method when you deposit into the casino, or alternatively they will add the amount you deposited onto your mobile phone bill.

That way, you don’t have to worry about finding your debit card or credit card when it comes to paying into the online casino, you can just use the mobile device that you are using to sign up to complete your deposit payment.

This makes using and depositing with pay by mobile casino sites easier than most traditional payment methods and e-wallets. In addition, if you are using a SIM Card with your mobile phone, then the balance will be deducted from your SIM Card when you deposit – be aware though, if you don’t have the required balance on your debit card then your transaction will be blocked.

On top of this, pay by phone methods are extremely trustworthy. Take Boku Payments, they work with some of the biggest companies in the world, including Google, Facebook, Microsoft, and other world-leading companies who all allow new customers to pay using their mobile number.

Any time you are considering joining the best slot sites, and want to use mobile billing to pay, you should feel assured that you are using a safe deposit method.

How to Deposit Using Pay by Phone Bill UK Sites

Making a mobile deposit is straightforward. Although the process can vary slightly from site to site, you usually follow the basic steps below:

  1. Find a site that offers pay by phone bill as an option. UK players can simply browse the licensed sites recommended right here at GamblingDeals, and click the link straight to your chosen casino’s registration page.
  2. Follow the on-screen prompts and provide some basic personal details to set up your account.
  3. Navigate over to the deposit or banking page, and select the pay by phone bill option. Then enter the amount you’d like to deposit along with your phone number.
  4. The casino website will send a confirmation text to your mobile phone via SMS. You can confirm the deposit, either by replying to the text or entering a unique code at the casino site.
  5. The deposit amount will be added to your casino balance and charged either to your next phone bill or your pay as you go account.

If you’re having trouble receiving the text, you may need to speak to your network provider. Some networks automatically block premium rate services, but if you speak to customer services, they should be able to unblock this for you.

Pay by Mobile Casino Pros and Cons

plus What we like

  • Quick and simple – depositing at pay by mobile casinos is a very quick and straightforward process that requires only a phone number, which you probably know off the top of your head;

  • Highly secure – never having to enter your bank details makes pay by mobile one of the most secure payment methods out there;

  • Responsible gambling – your transactions can’t exceed £40 a day, and £240 a month. While this will be a disadvantage to many players, they can be a helpful, natural way of limiting your spending;

  • Accessibility – if you’ve got a phone number, then you can use pay by mobile, which is accepted by the majority of UK online casinos.

minus What we don't like

  • No withdrawals – you can only deposit using pay by mobile services, so you will need to use another method to withdraw your cash;

  • Transaction limits – not a great option for high-rollers – a lot of players will be looking to spend more than £240 a month; 

  • Fees – you’ll find that one or two pay by mobile services will charge a small transaction fee;

  • Hard to manage spending – charging deposits to your phone bill can make it easy to ignore how much money you’ve been spending.

Pay by Mobile Casino Deposits

Though they all work in similar ways, there are a number of different pay by mobile services available at online casinos. Here are the biggest names to look out for.


Boku was founded in San Francisco in 2009, and is now one of the largest and most successful mobile payment companies in the world, operating in over 90 countries. This is the service you’re most likely to come across at pay by mobile casinos. 

Paying via Boku is extremely simple, and doesn’t come with any fees. You simply select Boku as your depositing method, enter your phone number and the amount you wish to deposit, and then confirm the transaction via the SMS message you’ll receive on your phone. As with other pay by mobile services, the deposit will be added to your mobile phone bill, but you’re free to start betting immediately. 

However, keep in mind that there is a £30 daily limit on your transactions – which is slightly smaller than some other pay by mobile providers – and European legislation means that you cannot exceed £240 in a month. Though this may frustrate some high rollers, it makes Boku a great option for players who either want or are trying to cut down on their spending. 


Zimpler is another global pay by mobile company that was founded in Stockholm in 2012. Zimpler works rather differently to standard pay by mobile services like Boku in that, though you still pay using your phone number, the money is charged to your bank account rather than to your phone bill or PAYG credit. 

The first time you use Zimpler you will have to set up an account that connects your phone number to your bank account, from which point on you can simply enter your phone number when depositing at your pay by mobile casino.

Not paying from your mobile network means that, unlike all other pay by mobile services mentioned on this page, you can both deposit and withdraw with Zimpler, which also isn’t bound by the £240 monthly limit set by European law. So, if you like the idea of pay by mobile payment methods, but want the flexibility afforded to alternative deposit options, then Zimpler might be your best fit.


Siru is a Finnish mobile payment company that provides a similar service to Boku, albeit on a slightly smaller scale. You will still find Siru at a number of the top-rated pay by mobile casinos UK, and it’s just as fast and convenient as its competitors. Again, all you need to do is choose your depositing amount, enter your phone number and confirm the payment.

As Siru is a standard pay by mobile service that charges your transactions to your phone bill, your transactions will be restricted to £240 a month. Unlike Boku, which limits you to £30 per day, with Siru you are restricted to £40 per transaction and gives your wallet a little more flexibility.

Siru will, however, charge you a transaction fee which, though small, is a bit of a disappointment. These fees will vary depending on which pay by mobile casino you’re depositing at, but will be declared before you pay.


Payforit is another payment method you can use at pay by mobile casinos UK. The same transaction and withdrawal limitations apply here, but you won’t be charged a transaction fee, which might make this a preferable alternative to Siru. 

Payforit’s only real distinguishing factor – which isn’t a bad thing – is that it features a two-step verification process to confirm the details of the transaction and provide a little bit of extra security. You won’t find Payforit at all of our pay by mobile casinos, but it’s a great option when available.


PayViaPhone is relatively new to pay by mobile casinos, and is becoming widely available. It works just like Boku, Siru and Payforit, and adheres to the same limits of £40 per transaction and £240 per month. 

As usual, you can’t withdraw using PayViaPhone, and there is also a 15% fee on every transaction, which will be deducted from your deposit. If you wanted to deposit £40, for instance, you would actually end up with £34. This is quite a high figure, so if you were to pay using PayViaPhone, we recommend depositing in small amounts in order to avoid the higher fees.

Claim a Bonus at a Pay by Mobile Casino 

All of the best pay by mobile casinos will offer a variety of bonuses to both new and returning players, and pay by mobile deposits can usually be used to qualify for said bonuses. This won’t always be the case, however, so check the bonus terms and conditions to see if you’ll need to use another deposit method to access your bonus. 

Here are some examples of the types of bonuses you’re likely to receive at pay by mobile casinos UK.

Matched Deposit

A matched deposit bonus will add a percentage of your deposit to your account as bonus funds, up to a specified amount. For example, if a pay by mobile casino was offering you a welcome bonus of 100% up to £50, and you made a qualifying deposit of £40, you would be given £40 worth of bonus funds. Of course, there’s no need to pay the maximum deposit, but every pay by mobile casino will set a minimum qualifying deposit amount, which is typically in the region of £10 to £20.

It’s worth keeping in mind though, that wagering requirements – which state how much you will have to wager in order to make cash withdrawals from your bonus funds – will be in place to make it difficult to convert your matched bonus into real cash. Generally speaking, it’s best to see a matched deposit bonus as a nice way of getting used to a new site without staking lots of real money.

Free Spins

Free spins are another common type of bonus found at pay by mobile casinos. They give you a set number of spins – which can sometimes only be used on specified slot games – when you make your first, qualifying deposit. 

These too will come with wagering requirements, however, and even though they are generally more clearable than those attached to matched deposit bonuses, we still recommend that you treat them as an opportunity to explore all the slots on offer before you start playing with real money.

No Wagering Bonus

Due to the frustrations that wagering requirements cause players who want to profit from their bonuses, a number of pay by mobile casinos now offer no wagering bonuses. As the name suggests, these are bonuses – usually free spins – that come without any wagering requirements, meaning that any winnings you might make from them are yours to keep. 

Don’t get too excited, though, as any potential winnings will be modest by design – and you will usually only have about 10 or 20 spins to work with – but it’s still nice to have the chance to withdraw some real cash from your bonuses. 

Alternative Payment Methods at Pay by Mobile Casinos

None of the pay by mobile services – with the exception of Zimpler – allow you to withdraw money at online casinos, so you will need to have another payment method that can handle your withdrawals. Besides, not every online casino will offer your preferred pay by mobile service, so it’s always a good idea to have more than one payment method at your disposal.

Here are some of the most popular alternatives.

Debit Card

No matter which pay by mobile casino UK you sign up for, debit cards will always be available for both deposits and withdrawals. Withdrawal times can be a little slower than some other available payment methods, but their widespread availability makes debit cards an option you can always rely on. Visa users with access to Visa Fast Funds may also be able to take advantage of fast withdrawals at sites offering them.

Apple Pay & Google Pay

Apple Pay and Google Pay are a natural alternative for pay by mobile users, and are just as easy to use. If Apple Pay or Google Pay is available on your iOS or Android device, which isn’t always the case, you can usually make deposits with a simple tap of your finger, or perhaps just a glance at your phone’s facial recognition camera.

Apple Pay and Google Pay facilitate transactions to and from your bank account, and so withdrawal times will be the same as a debit card payment, but there are few quicker alternatives when it comes to depositing at pay by mobile casinos. 


e-Wallets like PayPal, Skrill, and Neteller offer some of the fastest withdrawal times in the online payment sector. Making deposits is extremely quick too, especially for mobile users, as each of the aforementioned e-wallets all offer mobile apps that enable instant payments from your phone. 

Be aware, though, that a number of online casinos don’t accept e-wallets as qualifying deposit methods for their bonuses, so if you’re looking for a pay by mobile alternative in order to qualify for a bonus, check to see if e-wallets are accepted.


Paysafecard was founded in Vienna in 2000, and has since become the leading provider of virtual prepaid cards. Prepaid cards are similar to pay by mobile services in that they don’t require users to enter any bank details, but equally don’t allow them to withdraw, so if you’re after a withdrawing alternative, Paysafecard isn’t the way to go. 

If you simply want another deposit option, however, you can purchase a 16-digit Paysafecard voucher at most of your local stores and corner shops. You can then use your 16-digit PIN – the value of which can be between £10-£100 – to deposit at online casinos. But, like pay by mobile, there is a limit of £40 per transaction unless you make a Paysafecard account.


Trustly is an Open Banking payment method that was founded in Stockholm in 2008. It allows users to make quick, secure and direct payments from their online bank accounts, without having to enter any bank details, or being redirected to a banking app. 

Trustly is therefore just as secure as pay by mobile, and can also be used to withdraw, which makes it a great alternative for pay by mobile users. 

Best Pay by Mobile Slots

Playing at a Pay by Mobile Casino is pretty easy. Just make a deposit with your phone bill and play your favourite casino games. But which are the Best Pay by Mobile Slots you can play? There are hundreds of slots you can play at online casino, but not all of them have excellent Mobile Gameplay. That’s why we’ve selected some the of the Best Pay by Mobile Slots.

Below we will highlight some of the best slots you can play on Mobile Devices. You can play these slots when you’ve make a Deposit with your Mobile Phone bill.

Book of Dead


Book of Dead is the number one when we look at the most popular and Best Pay by Mobile Slot on the internet. The ancient themed slot is every month the most played slot on the internet. The reason why this slot is so popular is because it’s really easy to understand and it has a pretty good bonus. Book of Dead is a simple 5×3 reeled slot with the classic symbols on it.

When you get 3 Books you enter the Bonus Game. This is where you can win the real money. You have 1 special symbol that will expand when you have at least 3 of them on the screen. Hitting 4 or 5 of these symbols can give you a really good win.

The max win at slot is a 5.000x, which can be lower in comparison to the newer slots. But we think it’s way easier to hit a max win at Book of Dead in comparison to these new slots. Getting the bonus is also pretty common which is also very pleasant when you play an casino slot.

Wild Wild West Slot


Wild Wild West is also an old school looking slot. It’s just like you’re really in the Wild West when you open this slot. When you open the slot you see the sheriff logos and bull skulls, just like in a real saloon. The looks are already one of the things why you can try this slot, but there is much more to enjoy while playing this Best Pay by Mobile Slot.

The RTP of the slot is also pretty good. The average payout at Wild Wild West is 95,87%. This is pretty decent for an online slot. You can play this slot with from 2p per spin, which is very appealing for newer players. But if you want to go big you can spin with £4 per spin. And maybe you can hit the £4.000 jackpot with those spins!

Wild Wild West Slot has a load of fun features and symbols that you might expect from the theme. There are ways to win with wild bonuses and free spin features, as well as a useful autoplay option. That’s why it’s definitely one of the Best Pay by Mobile Slots.

Sizzling Hot Slots


Sizzling Hot Slots is one of the classic Fruit Machines. This is the slot machine you can find at the bar or at the gas station. On the reels you can find the classic fruits like the Watermelon, Lemon, Grapes, Cherries, Oranges and many more.

While playing Sizzling Hot Slots you can play with a minimum bet of 50p and a maximum of £2 per bet. And the maximum win you can get with these bets is 5.000x. That means you can win up to £10.000 per spin if you spin with £2. And for a Fruit Slot the RTP is also high. The RTP of Sizzling Hot Slots is 95,66%.

So if you fancy taking a nostalgic trip back down memory lane to the days of classic, feature-less pub fruit machines, then Sizzling Hot will be right up your street! A Classic Fruit Machine was the only thing missing in this list with Best Pay by Mobile Slots.



Released by NetEnt in 2012, Starburst was quick to make a space for itself in the upper echelons of the online slots world. The game remains one of the top titles today, thanks to its classic gameplay, win-both-ways paylines, and regular appearance in free spins offers.

As far as slots go, Starburst is pretty simple. With five reels and three rows, players must match shiny gems on the ten paylines — which are Win Both Ways — to be successful. As for extra features, there’s really only one: the expanding Wild. When it lands, it’ll cover the entire reel and substitute for all other symbols. It triggers a respin too, giving you an extra chance to complete some paylines.

Starburst’s volatility is low, meaning you can expect small but fairly consistent wins. Its return to player (RTP) is 96.1%, which is pretty average — it means theoretically £96.10 will be paid out as winnings for every £100 that’s bet on the game. The max win is 500x your stake.

Starburst is together with Book of Dead the top when it comes to the Best Pay by Mobile Slots. Starburst is since the launch in 2012 already one of the most popular slots on the internet. And they deserve their spot in the list of Best Pay by Mobile Slots!

Responsible Gambling

Although the low transaction limits at pay by mobile casinos can be a useful way of naturally restricting players’ spending, it’s easy to let bad habits develop if you aren’t careful. Here are some of the things we’ve identified as warning signs for problem gambling, as well as some advice on where to go if you think you need some help.

  • Financial trouble – if your gambling habits have landed you in financial trouble, or you’re struggling financially but are continuing to gamble, then you should ask for help. The UK Gambling Commission website provides a list of a number of charities that deal specifically with financial struggles;
  • Betting with what you can’t afford – if you find yourself betting money that you can’t afford to lose, it’s quite likely that you have a gambling problem. Get ahead of it by visiting, or by signing up to a self-exclusion tool like GAMSTOP, which allows people to block themselves from online gambling sites;
  • Your gambling is isolating you from friends and family – online gambling can be a very isolating pastime, and if it is beginning to impact your social life and relationships, you may be developing an addiction. If you need some help, GamCare is a charity committed to helping those suffering from or affected by problem gambling and addiction, and have round-the-clock support via phone, live chat and messaging;
  • Keeping your gambling habits secret – are you lying to your friends about how much you gamble? Concealing your gambling habits is often an early sign of problem gambling. If you’re gambling responsibly, you shouldn’t have anything to hide;
  • Constantly thinking about gambling – a preoccupation with gambling is a clear-cut sign of addiction and can lead to a lack of sleep and other unhealthy habits. As addiction is a recognised mental health illness, you can always seek help on the NHS website, or with your local GP.

If you require any more information on where you can go for help, advice and support, please visit our responsible gambling page.

Get Started at a Pay By Mobile Casino

Pay by mobile casinos allow you to make quick and secure deposits using only your phone number, which means you’re just 11 digits away from depositing and playing. Click through to sign up for a bonus at one of our recommended pay by mobile casinos, confirm your first deposit via the text message, and start exploring all these great sites have to offer. 


  • Are pay by mobile casinos safe?

    All of the pay by mobile casinos we recommend are licensed by the UKGC – the UK Gambling Commission – which affords player security through regulation. But, just in case you’re unsure, pay by mobile methods don’t require you to enter any bank details, so all your personal information is safe.

  • All kinds of games are available at pay by mobile casinos: slot games, table games, live dealer games, bingo, sportsbook, and many more. All you have to look out for is whether these games can be played with your bonus funds, but this will vary depending on the casino, so check the relevant terms and conditions.

  • Unfortunately, you can’t withdraw using pay by mobile services, but all pay by mobile casinos will provide a variety of alternatives when it comes to withdrawing. At least one of either debit cards, Apple Pay, Google Pay, e-wallets or Trustly will be available at your chosen pay by mobile casino, and can all cater to your withdrawal needs.

  • Depositing with Boku, Zimpler and Payforit is free, but Siru and PayViaPhone will charge a small transaction fee.

  • No, the UKGC banned credit cards at all UK pay by mobile casinos in April 2020. You can still use your debit card, though.
