How to Make a Phone Bill Casino Deposit – A Step by Step Guide

SMS billing deposits are so popular because they couldn't be easier to make. In fact, you can make a deposit in this way in just three simple steps:

Step 1 Pay by Phone

Visit the banking page of your casino site of choice and click deposit and select the ‘pay via phone’ option.

Step 2 Pay by Phone

Enter the amount you wish to deposit via mobile and then enter your mobile phone number. Deposits can be made from as little as £3, up to a maximum of £30 per day.

Step 3 Pay by Phone

Wait for a verification text message and then reply appropriately. This message will ask you to confirm the payment, either by sending a follow-up text or by sending you a four digit code.

What Exactly is Mobile Billing?

Mobile billing is, as the name suggests, the process of charging online payments to your mobile bill – rather than paying there and then via a more traditional payment method, such as debit or credit card or e-wallet.

Mobile billing is a popular depositing method, as it offers a lot of advantages over other payment services. You can learn more about the advantages of paying via this method later in this guide but the main things to know is that pay by phone bill payments are quick, straightforward and incredibly secure.

So, How Does Mobile Billing Work?

As we've just mentioned, mobile billing works by charging online payments to your monthly mobile bill. This means you can deposit at your favourite casino and pick up the cost at the end of the month when your bill arrives.

SMS billing isn't just reserved for those with monthly contracts, however. The payment solution can also be used by Pay As You Go users, and the charges are simply subtracted from your existing credit.

Accepted UK Mobile Networks

Pay by mobile services work hand in hand with mobile networks. Obviously, for charges to be allowed to be added to your phone bill, your network provider needs to be on board.

The good news is that almost all UK networks allow for these types of payments. This means that it shouldn't matter which operator you take your contract out with, you should still be able to make deposits with ease.

⚠️ That being said, it's always wise to double check with your network provider before making your first transaction. Moreover, if you ever find that your deposits aren't working for some reason, your network provider is who you should contact first.

In the UK, popular accepted networks include:

  • EE
  • Vodafone
  • Three
  • Tesco
  • O2
  • Virgin

Pay by Phone Bill Intermediaries

Much like e-wallet services (where you can choose between Neteller, Skrill, PayPal etc), there are many different brands for mobile bill payments and using phone credit. They all essentially operate in the same, with minor differences, in that these services apply the payment for you.

These services act as a middle-man, and therefore are called payment intermediaries. In the UK, Boku is the leading mobile payment company, but you may come across other brands too, such as Payforit and SIRU Mobile.

So if, for whatever reason, you want to avoid Boku casinos, you can still make a deposit with ease. Moreover, by not restricting yourself to simply one depositing method, you can enjoy a wider range of great casinos and game titles.

The Pros and Cons of a Pay By Phone Bill Casino

Now you know how these types of deposits work and how to make them, you're probably wondering why you'd want to make one in the first place. Sure, there are some negative sides to this payment method.

Yet, pay by mobile casino deposits offer many advantages over more traditional payment methods. Let’s dive in.

Pros:

  • Super quick access to funds
  • The convenience is unparalleled – all you need is your phone
  • Steps in the process ensure 100% safety
  • No need to remember any extra card/account details
  • Flexibility – pay by pre-paid or on contract

Cons:

  • Limited by maximum daily/monthly deposit amounts
  • Not every casino offers pay by phone as a method
  • Sometimes, bonuses are not extended to pay by phone deposits
  • No way to receive a withdrawal
AdvantagesDisadvantages

The Advantages

Thumbs up icon (advandages to pay by phone)

Phone deposits are incredibly quick and convenient. This is because you aren't required to enter any long bank or card details. Moreover, this also means they're safe to make anywhere – you needn't worry about who's looking over your shoulder as you only need to input your phone number.

These types of deposits can be made whenever and wherever you like, provided you have your device with you. Furthermore, phone payments are always processed immediately. This is because, as there's no actual payment being made until a later date, there's no need to wait around for your bank or card provider to approve the transaction.

Phone billing is one of the most secure types of deposit you can make at any internet casino. This is because you only ever need to supply your number to make a deposit. As such, you don't have to exchange any personal details or card information with the casino, and therefore it's impossible for your bank account to be compromised.

Many players worry about payment security, as we've all read horror stories about internet fraud and hackers. SMS billing payments remove this worry and allow you to make deposits safe in the knowledge that your details are protected.

The Disadvantages

Thumbs down icon (disadvandages to pay by phone)

Despite the hefty list of pros, there are also some cons to pay by phone billing. And while we don’t think they’re serious enough to deter anyone from using this method, you still need to be aware of them to make the best decision for you.

First, you’re obviously limited by the daily deposit amount limit of £30. Simply put, this can be an advantage too if you’re someone who can get carried away when gambling – this could be a nice way to check and balance yourself so you don’t spend more. However, for people with larger budgets, this is definitely a con.

Second, not every casino has recognised the need of having pay by phone as an option on their page. In this case, you’ll need to make sure the casino you’re wanting to deposit funds into does offer it, or find other ways to deposit.

Third, welcome bonuses and promotions are sometimes not offered to players who pay by phone. This means that you wouldn’t be getting any of the promised extra cash if you choose this payment method, which is the most unfortunate.

What to Expect from a Pay with Phone Casino (FAQ)

Many of the UK’s biggest and best casinos accept deposits made via this method. This means that you don’t need to make any sacrifices, and should be able to find a casino which suits your preferences perfectly.

Below, we’ve listed some of the things you should be aware of on pay by mobile casino sites.

Are There Any Transaction Fees?

At any decent gambling site, all online casino deposits should be completely free to make. Whilst many phone services do charge transaction fees, these are so low that casino sites often absorb the cost.
After all, they know that the depositing method could attract new players and so it's more beneficial to them to provide flawless service. This means you can keep all your funds to play more great titles.

Are There Any Daily Depositing Limits?

One of the biggest disadvantages of using phone billing at online and mobile casino sites is that your payments are quite heavily restricted. Phone billing services will only allow you to make £30 worth of transactions per day.
Whilst this is annoying, the limit is there to make sure players aren't borrowing too much money. As many players will only be charged for their deposits at the end of the month when their phone bills come through, it can be very tempting to make more deposits than you can afford.
Essentially, the £30 limit is there to ensure the services can carry on operating. If there was no limit, it would be hard to convince phone networks to allow payments to be made.

How Do I Withdraw My Winnings?

Although pay with phone services allow players to make easy and quick deposits, they do not allow for withdrawals. When you think about it, this makes sense, as you haven't shared any banking information with the casino and therefore they have nowhere to send the money to. Moreover, who would want their winnings to be paid out in phone credit?
If you have used an SMS billing service to deposit at a casino, you'll be required to link a different payment method in order to make withdrawals. This could be an e-wallet service, a bank account, or a debit or credit card.

Are Casino Bonuses Still Available?

At many casinos, players can still pick up bonuses and promotions even when depositing via pay by phone. That being said, some casinos do restrict what depositing methods are eligible for bonuses. This means that you always need to read the casino’s bonus policy carefully, and the terms and conditions.
If you’re ever unsure about a bonus, don’t hesitate to get in touch with customer support before funding your account.

What Is The Minimum Deposit?

One of the many benefits of pay by phone is that the depositing method usually has low minimum amounts. The minimum deposit for pay by phone users can vary from casino to casino: at some sites it is as low as £3 and at some sites it is as high as £15. To find out the minimum deposit at a specific casino, read the casino’s terms and conditions and depositing guidelines.

Is There A Limit To What I Can Deposit?

All pay by phone deposits have a maximum depositing limit of £30 per day. This is due to the fact that, essentially, a pay by phone deposit is a loan – you don’t pay for the deposit until you pay your monthly phone bill. As such, deposits are capped so that player’s cant rack up unreasonable debts and so that the service can function in a responsible manner.
The £30 per day limit is enforced at every pay by phone casino UK. Some casinos impose their own limits on top of this, such as a £10 maximum deposit per pay by phone transaction.

Can I Withdraw My Winnings Via Phone Bill Too?

Unfortunately, phone bill services do not accept withdrawals. This is because pay by phone bill services don’t require you to share your banking details and, therefore, the casino wouldn’t know where to send your money.
Pay by phone users must always withdraw via an alternative payment method, such as credit/debit card or e-wallet. Luckily, at the best pay by phone casinos, this process is straight-forward and secure.

Can I Predefine Limits/Restrictions To My Deposit Amount?

One of the biggest appeals of pay by phone is that the method already comes with tight depositing restrictions. This makes it perfect for budget players and for those who don’t want to run the risk of being able to deposit large amounts in one go.
All pay by phone deposits are capped at £30 per day. If you want to impose smaller restrictions on yourself, you should speak to customer support at your casino of choice about your options.

Where Can I Find Pay By Phone Casinos That Are Not Boku?

It's easy to find casinos that offer pay by phone deposits by intermediaries other than Boku. If for some reason you have an aversion to the most popular sms billing option there is, check out Payforit, SIRU and Fonix. Specifically, venture out to find the brands that have adopted their services to locate casinos that offer an alternative to Boku. While Boku might have the widest reach, there are definitely other ways to pay too.
