Pay by Phone Slot Sites - Updated February 2026

Pay by Phone is an intuitive and innovative payment method which allows you to make deposits at online casinos and slot sites using your mobile phone contract. The funds you deposit are then charged on your next mobile bill. It’s a fantastic option for those seeking a stress-free, simple, and secure way to deposit funds, and today, there are more Pay by Phone sites than ever before.

Here at BingoParadise, we understand that finding reputable slot sites is hard enough, but when you’re looking for a specific payment method, finding the right site can be even harder. That’s why we’ve put this handy page together, showing you exactly how Pay by Phone works – including its advantages and disadvantages – and the best Pay by Phone slots sites you can join today.

To kick things off, let’s look at how Pay by Phone actually works.

How Does Deposit By Phone Bill Work?

Making a deposit using Pay by Phone is incredibly straightforward; it’s far easier than many e-wallet and voucher-based schemes such as PayPal and Paysafecard.

The scheme works by applying a charge to your phone bill, much like the charges that incur when you use extra data outside of your data plan. Any deposits you make via Pay by Phone are simply added to your next phone bill. If you’re on pay-as-you-go, you can also use this payment method – you’ll just need to ensure you have enough credit topped up.

If you like the sound of Pay by Phone and want to know how to actually use it, read on.

How to Use Pay by Phone Methods to Deposit

Firstly, you need to head to the “Cashier” at your chosen slot site and find a Pay by Phone option. The three major ones include Boku, PayForIt, and Zimpler. Once you’ve selected Pay by Phone, you’ll be prompted to enter the amount of money you want to deposit using your phone bill.

A new screen will appear, and you’ll be asked to enter your phone number. A confirmation text will then be sent to this phone number, which will display details of the payment—including how much it’s for and the site at which it will be made. You must respond to the SMS message to confirm your payment.

Once you’ve replied to the SMS, the payment will be finalised and the funds will be available in your casino account immediately. It’s simple, straightforward, and hassle-free.

In order to use Pay by Phone, you’ll need to make sure that your mobile phone plan allows you to make purchases or go outside of your regular spending plan. You’ll also need to use a valid mobile phone carrier, and not every UK phone company supports it. However, O2, EE, and Vodafone all allow it, so it’s unlikely you’ll find yourself unable to use it.

Benefits of Pay By Phone

There are many clear benefits to using a Pay by Mobile method, but depending on your budget and style of play, these might not outweigh the negatives.

Fast and Fee-Free

Players looking to use Pay by Phone to make a deposit at online slot sites will find themselves able to use their funds immediately. This is thanks to the fact that all deposits made using Pay by Phone are credited to your slot account straight away.

There are also no charges or fees attached, so the amount you deposit is the amount you’ll see added to your phone bill at the end of the month. However, it’s worth remembering that some casino sites will charge fees when you use Pay by Phone.

You Don’t Need to Input Card Details or Remember Passwords

Another major benefit of using Pay by Phone to make deposits is that you don’t need to remember any card details or passwords. When you make the deposit, the only thing you need to input at the slot site is your phone number. Once the SMS verification has been processed, the payment is completed.

It is Secure and Private

As you’re not providing any sensitive financial information, making deposits using Pay by Phone is an incredibly secure solution. The slot site doesn’t store any financial information, and the only time you’ll ever actually need your card or bank information is when you pay your phone bill.

For those without a UK bank account or a debit card, making a deposit at Pay by Phone casino sites can be simplified. As I mentioned earlier, the only thing you need is a phone number, and provided your contract allows, you’ll be able to deposit without needing a bank account or debit card.

It Could Help with Bankrolling

Some players have even reported that using Pay by Phone allows them to monitor their casino bankroll – i.e., how much they’re spending each month – as it’s all itemised on their phone bill at the end of each month. This is a valid reason for using the payment method, although you should be careful not to deposit so much that you’re left facing an unexpectedly high phone bill at the end of the month.

It is Easy

Above all else, making deposits via Pay by Phone is easy. You don’t have to worry about entering any banking/card details online. It’s straightforward, and funds deposited are credited to your account immediately. What’s more, with more slot sites accepting Pay by Phone deposits, finding an online casino that offers this payment option is, thankfully, relatively straightforward.

Disadvantages of Pay By Phone

Personally, I don’t like Pay by Phone as a deposit option. I feel bad criticising it, especially as I have never used it as a player (only to test the service for this guide and my guide to Pay by Phone on bingo sites), but that’s because the negatives are far greater than the positives for me.

There are a number of drawbacks, including:

It Can’t Process Withdrawals

Arguably the biggest disadvantage of using Pay by Phone to deposit funds is the fact that the payment solution is unable to process withdrawals. This means you’ll need to set up a separate payment method to process withdrawals.

This may seem like a minor inconvenience, but it means you’ll likely be asked to undergo additional security verification checks.

It also renders the service useless for anyone who wants to limit how many slot sites have their financial information. Unless you lose all of your funds and have nothing to withdraw (and if you’re playing to lose, you’re going about it all wrong), you will need to enter a debit card, e-wallet, or other option.

In my personal experience, if a deposit method can’t be used to withdraw, a site will nearly always insist on a bank transfer, which is often the slowest and most fiddly payment method you can use.

Low Deposit Limit

Another major downside is the low maximum daily deposit limit. Regardless of which Pay by Phone provider you use, the most you’ll be able to deposit in a day is just £30.

While this may suit small-stake players, anyone looking to deposit large sums of money will find themselves unable to do so. It’s yet another reason why Pay by Phone has failed to become a leading banking option at most slot sites.

You May Be Excluded from Certain Bonuses

Most slot site promotions (particularly those offered to new players) are only available when claimed with a certain payment method, usually a debit card.

This means that deposits made via Pay by Phone may not be eligible for promotional offers. You should always check the terms and conditions of a bonus before depositing to make sure your chosen payment method is accepted.

The easiest way to check is to find the full bonus terms and then use the “find” function on your keyboard (CTRL and F for Windows; CMD and F for MacOS) to search for your payment method. For many years, I stuck with PayPal casinos and PayPal bingo sites, so I got into the habit of doing this for every welcome bonus.

If you don’t use debit cards, it’s a good habit to adopt.

It is a Form of Credit Gambling

My biggest criticism of Pay by Phone services is that they are a form of credit gambling. It’s the sort of “use now and worry about it later” option that could land problem gamblers in a lot of trouble.

Proponents of using these methods on slot sites have argued that a £30 daily limit would prevent problem gambling. But I was broke for most of my early 20s, and I was also a keen gambler. Trust me; if I had been depositing and losing £30 a day before receiving a collective bill at the end of the month, I would have been in serious financial trouble.

It’s all relative. You don’t need to blow tens of thousands of pounds to be a problem gambler. If you only have a few quid to scrape together at the end of the month, a bill in the hundreds is enough to send you over the edge.

Is Pay by Phone Secure?

Using Pay by Phone to fund your online slot account is incredibly secure, and this is largely thanks to the fact that you don’t need to enter any card or bank account details. When you make a payment through a Pay by Phone provider, the only information you need to provide is your phone number. A confirmation text will then be sent to your mobile phone, but at no point do you need to hand over any card details.

When it comes to making the payment, the charges are simply added to your next mobile phone bill, which is then paid either by Direct Debit or by card, whichever way you’ve chosen to set it up.

Other Deposit Methods

While Pay by Phone is a popular payment method, it’s not suitable for all. Thankfully, a number of other payment methods are available to use at slot sites, and below, we look at some of the most common of these:

Debit Cards

All reputable slot sites accept most major debit cards, including VISA, MasterCard and Maestro. Making a deposit using a debit card is instant, and there are no fees associated with doing so.

Once you’ve made a deposit with your card, you will then only need to enter your CVV code in future as the slot site remembers (securely) your long card number and expiry date.

In the UK, players can’t use credit cards at online gambling sites. The practice was outlawed way back in 2020, as it was deemed to be irresponsible gambling. It’s 2025 as I write this, so 5 years have passed. Back then, I thought Pay by Phone would soon be outlawed as well, as it’s also a form of credit gambling. That has yet to happen, but it’s important to remember that regulations move very slowly.

It might seem like the UK Gambling Commission is taking a heavy hand to the industry and implementing rapid changes, but they are often in the pipeline for months and even years before they come into force.

Skrill

Skrill and online gambling are synonymous, and it’s one of the most popular payment methods offered at online casinos. Skrill is a type of e-wallet, and the company is part of the well-regarded PaySafe Group.

To use Skrill, you first need to add funds to your Skrill account. When making a deposit at a slot site, just enter your Skrill email and confirm the transaction. Your deposit will instantly be credited to your account.

Skrill is also able to process withdrawals very quickly, and once a slot site approves your withdrawal, the funds will be available in your Skrill account immediately. You can then withdraw them directly to your UK bank account.

PayPal

While the number of sites offering PayPal as a deposit/withdrawal method is small (due to PayPal being very picky on who they work with), it’s a very popular method thanks to its simplicity, security, and the fact that no fees are attached.

It works like Skrill – but you can also make deposits using your debit card through PayPal. Another major benefit of using PayPal at online slot sites is that withdrawals from PayPal to your bank account are instant.

This means that once a casino approves your withdrawal, the funds are available in your PayPal account immediately. You can then withdraw them instantly, with the funds appearing in your bank account just a few minutes later!

Neteller

Neteller is another popular e-wallet accepted at most online slot sites.

It’s not as well-known or popular as Skrill or PayPal, but it works in a near-identical fashion, and is very easy-to-use. Funds from a Neteller account can also be withdrawn to a UK bank account quickly and easily, and the company has brought out their own Net+ card so you can actually spend money in your Neteller account using a prepaid Mastercard.

Trustly

Trustly is an intuitive UK-focused payment method that allows players to make instant deposits and withdrawals at online gambling websites. Through the Trustly platform, you login directly to your online banking, and Trustly automatically makes a payment to a slot site.

This means that a bank transfer is now instant, when it used to take 2-5 days. Trustly is also beneficial when it comes to withdrawals, as withdrawals are credited to your bank account as soon as the slot site approves them.

Paysafecard

Paysafecard is a prepaid voucher option available at most online gambling websites. It allows you to purchase a voucher for cash in thousands of UK stores, and, using this voucher, you can deposit at the slot site you like.

Each voucher has a unique 16-digit code which you enter when making the deposit. Paysafecard can’t be used to make withdrawals, however. This means you’ll need to register another payment method to make withdrawals (usually be a bank account).

Cryptocurrencies

Over the past few years, cryptocurrencies – mainly Bitcoin and Ethereum – have become increasingly popular payment options at online gambling websites.

This is largely thanks to their privacy-centric nature, the speed at which transactions are processed, and the low fees. However, few UK-facing slot sites have chosen to accept cryptocurrencies due to the difficulties in carrying out Know Your Customer (KYC) checks.

It’s likely we’ll see Bitcoin and Ethereum offered at a number of sites in the future, once clearer guidance is provided by the UK’s Gambling Commission on what online gambling operators need to “verify” players.
