Boku – Pay by Mobile slots

Boku has become the leading ‘pay by mobile bill’ online casino payment method available to casino players in the UK and in other jurisdictions. The company was founded in 2003 by two entrepreneurs (Glyn Smith and Thomas Kirk) who came up the concept of allowing consumers to make purchases using their mobile phone. The idea was that the purchase could be made using a phone number, mobile-only and certain carriers only. The customer would then pay for their purchases when the time came to pay their mobile phone bill.

The company began in quite humble circumstances – in Chesterfield in Derbyshire in the United Kingdom. Originally called Vidicom, the early success of this company inspired them to seek capital from US investors so that they could expand into the United States. This was successful and the company bought a rival called Boku in 2009. Vidicom absorbed Boku but decided to rename themselves with the name of the company they had just purchased, moving their HQ to Delaware. Over the next year Boku swallowed up two other rivals – Mobilcash and Paymo.

In 2012 Boku decided to go global, with countless new investors coming on board. It became a public company in November 2017 with an initial valuation of £125 million. The company how has over 170 carriers on board across the world in 50 or so jurisdictions, plus offices in San Francisco, London, Singapore, India, Germany and seven other countries.

Why Use Boku Pay by Mobile at Online Slots Sites?

Boku is the most well-known ‘pay by mobile’ service generally offered by online casino brands all over the world. There are advantages and disadvantages to the service (as will be discussed later) but the main advantages are safety and anonymity. Although you must have an account with the online casino you wish to make a Boku payment at (note – Boku tends to style itself as ‘boku’ with a small ‘b’), you do not have to share any other details with them, such as bank details or debit or credit card numbers, or eWallet account details. All you need to supply is your mobile phone number.

Your anonymity is with your bank. In some jurisdictions, while online gambling is legal (or at least technically not illegal) banks are either forbidden or are loathe to finance transactions to any kind of online gambling account. By using Boku you can, in a way, connect your online casino account to your banking account without your bank even realising what you have done. By funding your online casino account via your mobile carrier account, you are simply adding ‘debits’ to your eventual mobile phone bill.

When the times comes to pay the bill, as far as your bank is concerned you are simply paying your mobile phone bill. This will bypass any issues you may have making payments to any kind of online banking account while helping to preserve your complete anonymity.


  • Nothing to set up if you already have a mobile phone account
  • Quick and painless
  • You can easily keep control of your payments via your mobile phone bill

Are there any disadvantages?

  • Cannot be used with all mobile carriers and some types of account
  • No withdrawals
  • Limited deposits

Is it easy to use Boku Pay by Mobile at Online Slots Sites?


First and foremost, mobile phone carriers do not operate as the providers of credit facilities. Although you often hear tales of children conjuring up massive mobile phone bills because of game microtransactions, mobile phone carrier companies take steps to prevent that from happening. For most Boku Pay by Mobile deposit providers there is a limit to how much you can deposit in one day, and that amount is often £30. There may also be limits on the weekly and monthly spends too.

To use Boku Pay by Mobile at a casino where it is offered, you need to head to that casino’s cashier section. Choose Boku as your payment method and the amount you want to deposit, up to that maximum of £30 (or the maximum amount as offered by the casino). You will also have to enter your mobile phone number too.

You should then receive an SMS message to your mobile phone asking you to okay the deposit. Once you have replied to this as requested, your deposit will be completed.

Note that Boku Pay by Mobile is only available with certain carriers and certain types of account. In the UK Boku is only available with Three, O2, EE and Vodafone. You are unlikely to be able to use Boku if you only have a ‘pay as you go’ account.


Boku Pay by Mobile is strictly a ‘one way only’ payment method. You cannot use your casino winnings as a means of paying your mobile carrier account. That means you cannot use Boku Pay by Mobile for withdrawals.

The use of Boku Pay by Mobile does come with a fee attached and unfortunately as a percentage of your deposit it is one of the most expensive. At most online casinos you can expect to pay around £2.50 per Boku Pay by Mobile deposit. Therefore, when you make a Boku Pay by Mobile deposit it’s best to deposit the maximum amount even if you do not intend spending that much money all in one go.
