What are pay by phone slots?
Pay by phone slots are casino games that let you deposit cash into your gambling account using your mobile phone bill or prepaid credit.
It’s an alternative to traditional online banking methods like debit cards and e-wallets, and it’s well-suited to you if you’re a mobile-first player.
Most casinos that offer this option use services such as Boku, Siru, or Payforit to process transactions.
It works with any UK phone number, and you don’t need to share your banking details with the casino. Simply enter your number, confirm the deposit through SMS, and the payment will be added to your next mobile phone bill.
It’s private, simple, and ideal if you want to pay for gambling later. On the flip side, though, you can usually only deposit a small amount (up to £30) and you’re often charged a processing fee.
Step-by-step: play mobile slots using pay by phone
It’s easy to sign up for casinos that support pay by phone bill slots. Follow these steps to register and charge your casino deposit to your upcoming phone bill:
- Choose a casino: Select a UK-regulated online casino that supports pay by phone. At Smashing Life, we recommend Fruity King, JeffBet, and Spinzwin.
- Create an account: Start the registration process. You’ll need to provide your name, address, date of birth, and other key details to complete the sign-up steps.
- Choose pay by phone: Head to the cashier and select ‘Pay by Phone’ as your preferred payment method. It might also be listed as Boku, Siru, Fonix, or Payforit.
- Decide deposit amount: Enter how much you’d like to deposit in the provided box. You usually need to deposit between £10 and £30 with this method.
- Enter phone number: Provide a valid phone number in the box provided to receive a validation code by SMS.
- Confirm the transaction: When you receive the SMS, copy the validation code and enter it into the box provided by the online casino.
- Check your balance: The payment should be processed instantly and reflected in your balance within seconds. If the deposit is delayed, contact the casino’s customer support team to follow up.
- Play online slots: With cash in your account, you’re ready to play online slots. Enjoy top games like Starburst, Big Bass Bonanza, and Gonzo’s Quest on your phone.
Benefits of pay by phone slots
This is an undeniably secure and convenient casino payment method. The benefits include:
✅Highly secure: Using pay by phone at an online casino is exceptionally safe, as you don’t need to give away your bank, card, or e-wallet details. Simply provide your phone number, confirm through SMS, and the payment will show on your next phone bill.
✅Fast deposits: All pay by phone deposits are processed instantly and will reflect in your casino balance within seconds. This is faster than a bank transfer, which can take hours or even days to reach your account.
✅Android & iOS compatibility: Pay by phone is a mobile-first payment method at online casinos and is compatible with all iOS and Android devices. As long as you have an active UK phone number, you can use this method to fund your account.
✅Supports responsible gambling: When you top up your account with your mobile phone bill, you’re often restricted to deposits of £30 or less. These lower limits support responsible gambling and make it much easier to bet within your means.
✅Mobile-exclusive bonuses: Some casinos run exclusive bonuses for players who deposit and play on mobile devices. This might be free spins or a unique deposit-match bonus for mobile players, and a pay by phone payment unlocks the promotion.
✅Bet now, pay later: Credit card deposits are not permitted at British casinos due to UKGC regulations. But you are permitted to charge your deposit to your phone bill, which you pay later. This is a viable way to manage your bankroll and spread your payments, but you should always gamble responsibly and avoid spending beyond your means.
Drawbacks of pay by phone bill slots
Overall, paying for slots on your phone makes a lot of sense for many players. But you should also consider these drawbacks before choosing this as your preferred deposit method:
❌Low limits: At most online casinos, you can only deposit between £10 and £30 with this method. This is lower than the caps applied to debit card and e-wallet payments, which are more suited to higher-budget players.
❌Processing fees: Many online casinos charge a fee for pay by phone deposits, typically 15%-25%. You’ll see this charge on your next phone bill. If you regularly top up your casino account, these processing fees will quickly add up.
❌No withdrawals: You can’t withdraw your winnings to your mobile phone bill – this is a deposit-only method. If you’re lucky enough to win while playing pay by phone bill slots, you’ll need to use an e-wallet, debit card, or bank transfer to cash out.
💬Editor’s Tip: “With all pros and cons considered, the benefits outweigh the drawbacks if you’re a low-budget casino player. The £10 to £30 deposit limits shouldn’t bother you, and the added security and convenience make pay by phone deposits well worth trying.”
Top pay by phone slot providers & payment services
Online casinos use several payment service providers to process pay by phone deposits, including:
Boku
Boku is the biggest pay by phone payment provider at online casinos, used in the UK and at least 60 other countries. You can only use Boku for deposits, and at most casinos, the standard limit is £30. Most casinos don’t charge you for depositing with Boku.
You should also be mindful of your network’s mobile monthly cap, which is often around £300 when paying with Boku. You can check the terms and conditions listed by your phone network if you’re unsure.
Payforit
UK-based Payforit is another leading pay by phone payment provider trusted by online casinos. As with Boku, a daily deposit limit of £30 is standard, while the minimum payment required is usually £10.
Millions of Brits use Payforit for secure online school payments, so if you already use it for this purpose, it’s a handy option for topping up your online casino account.
Siru
Though most commonly seen in Scandinavian countries thanks to its Finnish origins, Siru is a supported pay by phone deposit method at some UK online casinos.
You’re often charged a processing fee when using Siru, ranging from 15% to 25%. The fee won’t be taken from your deposit, but it will reflect on your phone bill. Like the other methods introduced, you can usually add only up to £30 per day with Siru.
Fonix
You might also encounter an online casino that accepts mobile deposits through Fonix. Sometimes branded simply as “Pay By Mobile,” Fonix is used across industries for subscriptions, concert tickets, and other products and services.
In the UK, you can use Fonix to deposit and fund your slot gameplay at some casinos, though it’s not as widely used as Boku or Payforit. Fonix fees vary by transaction and depend on your network provider, so read the terms and conditions for clarity.
💬Editor’s Tip: “If you’re looking for pay by phone but can’t find it, the casino might list the option as the service provider’s name (Boku, Payforit, Siru, Fonix, etc.). This is akin to the casino supporting e-wallet deposits, but listing them as PayPal, Neteller, and Skrill.”

Key terms & conditions
An online casino bonus is only as good as its terms and conditions. Before signing up and depositing with pay by phone, check for the following:
- Minimum deposit: This is the minimum amount you must deposit to activate the bonus. At many UK casinos, it’s £10.
- Timeframe: The bonus is valid only during a specific window. You might have 24 hours after account registration to make your first deposit, then 7 days to use the bonus cash or spins before they expire.
- Wagering requirements: Most bonuses at UK casinos come with wagering requirements. This figure indicates how much you must gamble before cashing out any winnings. Requirements typically range from 10x to 50x at UK online casinos.
- Supported payment methods: Often, Neteller and Skrill deposits are excluded from promotions. You’ll need to check that pay by phone is accepted for the bonus. If not, switch to a debit card to make your first deposit, then use your mobile phone to fund subsequent payments.
- Eligible games: You can only play selected games with bonus cash or free spins at an online casino. Always check which games are listed in the terms and conditions, and make sure you place qualifying wagers on eligible games.
- Max conversion: All bonuses come with a maximum conversion amount, also known as a win cap. This limits the amount you can win when using your bonus, typically 10x to 100x.

Security and safety of pay by phone Slots
Pay by phone as a deposit method at online casinos is inherently safe. You don’t need to give the casino your card or bank details, which adds an extra layer of security compared to making a debit card or bank transfer deposit.
The SMS verification step also ensures security, as you must respond to the message with the correct validation code for the deposit to be processed. If you don’t enter the code, the deposit won’t be added to your phone bill, protecting you against fraud.
Reputable pay by phone service providers like Boku, Payforit, Siru, and Fonix also operate legally and adhere to secure financial policies and procedures. This gives you peace of mind when using this payment method to fund your account.
We also recommend taking these extra steps to ensure you’re gambling at a legitimate pay by phone casino in the UK:
- UKGC licence: For a casino to legally operate in the United Kingdom, it must be regulated by the UK Gambling Commission. You can independently check the register to confirm that your chosen casino is licensed. If not, stay away.
- SSL encryption: Always verify that a site uses SSL before signing up. You can use a third-party tool like SSLShopper to confirm this. This is vital because it creates a secure, encrypted connection between your browser and the web server, preventing hackers from stealing your financial and personal information.
- Independent auditing: The gold standard for online casinos is eCOGRA certification. This confirms that the random number generators (RNGs) used in the casino’s games are fair and offer a genuine, random chance of winning. Another accredited testing organisation is iTechLabs, which provides a similar level of assurance that the games are fair.
- Customer support: The quality of a casino’s customer support is also crucial. The most trustworthy sites offer 24/7 customer support through live chat and over the phone. You may also want to check Trustpilot reviews to verify how helpful a casino’s support really is.
Deposit Limits, Fees, and Withdrawals
Every online casino has different deposit limits, fees, and processing times. That said, the terms are relatively consistent where pay by phone deposits are concerned:
| Payment Method | Daily Deposit Limits | Processing Time | Fees |
| Pay by Phone (Boku, Payforit, Siru, Fonix) | £10 to £30 | Instant | 15-25% |
Not every casino charges fees for pay by phone, but those that do often charge between 15% and 25% per transaction. If you don’t want to incur these fees, consider an e-wallet like PayPal, Neteller, or Skrill as an alternative.
You’ll also need to choose an alternative method to cash out your winnings, as withdrawals via pay by phone aren’t possible.
Again, we recommend an e-wallet for your withdrawals, as they come with zero fees and fast processing times (often within 24-48 hours at most online casinos).
Responsible Gambling with Mobile Slots
When you play pay by phone slots, you must gamble responsibly. Responsible gambling is a mindset that requires you to set your limits, stick to them, and adjust your stakes so you can bet within your means.
Every gambler is different, so it’s up to you to decide how much you can afford to wager and lose. Helpfully, legitimate pay by phone casinos in the UK offer a suite of responsible gambling tools to help you bet appropriately. These include:
- Deposit limits: You can set daily, weekly, or monthly deposit caps to control your spending. Once you reach the limit, the casino blocks subsequent deposits.
- Loss limits: Loss limits restrict how much you can lose within a set timeframe. When you hit the threshold, your gameplay is restricted.
- Session time limits: This tool lets you set a maximum session duration. Once your time expires, your gameplay pauses, and you need to take a break.
- Reality checks: These notifications appear at regular intervals and display the amount of time you’ve spent on the site and how much you’ve wagered. They can help you stay aware of your gaming session and take breaks.
- Time-outs: They temporarily suspend your account for a predetermined period, giving you time away from the platform.
- Self-exclusion: For a more permanent period away from the casino, set up a self-exclusion for six months to five years.
If you feel like you need help and are worried about the nature of your online gambling, you might find these resources helpful:
- GamCare: Founder of the National Gambling Helpline. Contact 0808 8020 133 for free, confidential support over the phone.
- GambleAware: Access free support tools and advice. Tools include a gambling harms assessment and a free gambling spend calculator.
Pay by Phone vs. Other Payment Methods
You’ll know that pay by phone isn’t the only accepted payment method at online casinos in the United Kingdom. Use the comparison table below to weigh up the various options and to consider which is most appropriate for you:
| Payment Method | Examples | Main Benefit | Main Drawback | Best For |
| Debit card | Visa, Mastercard | Highly convenient & instant | You need to share your details with the casino | Players who want a simple, familiar way to deposit directly from your bank account |
| E-wallet | PayPal, Neteller, Skrill | Fee-free deposits and fast withdrawals | E-wallet deposits are often excluded from casino bonuses | Players who value faster withdrawals and an extra layer of privacy |
| Pay by phone | Boku, Payforit, Siru, Fonix | Deposit by providing only your phone number | Relatively low deposit limits apply (£10 to £30 daily) | Casual players making small deposits who prefer charging funds to their mobile bill |
| Digital wallets | Apple Pay, Google Pay | Convenient mobile deposit method when playing on your phone | Not usually available for withdrawals | Mobile-first players who want quick, secure deposits using biometric authentication |
| Prepaid cards & vouchers | Paysafecard, Neosurf | Helpful for managing limits and gambling responsibly | Withdrawals aren’t supported | Budget-conscious players who want strict spending control |
Tips for Choosing the Best Pay by Phone Slots Casino
You’re now ready to choose an online casino that accepts pay by phone. Here’s how to make the right choice:
- Always go licensed: Never play at offshore online casinos in the UK. You have zero recourse or protection if something goes wrong. Only ever play on UKGC-licensed platforms.
- Game variety matters: The best online casinos offer thousands of games from dozens of top providers. Don’t settle for less – browse the platform’s game library before completing the registration process and confirm it’s up to scratch.
- Check payment T&Cs: Scratch the surface and check that pay by phone is supported. Then, check the payment processing time and fees, and only sign up for casinos that make your funds available instantly.
- Customer support you can rely on: Don’t underestimate the importance of quality customer support. You might need them to follow up on a payment or advise on a withdrawal delay. Choose casinos that offer 24/7 customer support through several channels.
The Future of Mobile Slots & Pay by Phone Tech
The next wave of mobile slots will be defined by speed, security and smarter design. With 5G connectivity becoming standard, you can expect near-instant loading times, integrated live features and smoother gameplay with fewer interruptions.
This is especially important for pay by phone users, where quick authentication and payment confirmation improve the overall experience.
Stronger encryption and biometric security (fingerprint and facial recognition) will make mobile deposits safer than ever, reducing fraud risks while keeping transactions simple.
On the game design side, developers are building more interactive slot mechanics, including skill-based bonus rounds, social features and adaptive gameplay tailored to mobile screens.
Looking ahead, blockchain and crypto integrations could further boost transparency, though cryptocurrency payments are still not permitted in the UK market.
Conclusion: Why Pay by Phone Slots Are the Future
Pay by phone deposits at online casinos are frictionless and fast. Enter your phone number, submit the verification code, and your funds will reflect in your account instantly. You can then settle the payment when you pay your next phone bill.
This highly convenient payment method is more secure than debit card or bank transfer payments, as you don’t need to share sensitive payment data with the casino.
Though withdrawals aren’t supported and fees may be charged, it’s a viable option for budget-conscious casino players looking for secure, instant payments.
