The first thing you need is a number from one of the supported UK network operators, such as EE, O2, Vodafone, or others. There are two types of billing systems you can use, as you can see below:

Because this isn’t like other digital banking systems, the amount you can send is fairly limited, or in this case, £40.

How We Rate Payment Methods

We cover all bases when rating available payment methods. Our transparency and detailed rating criteria help separate the best from the rest. Factors specific to the topic are also considered, such as the ones for online gambling banking listed below.

  • Transaction Times – How quickly are deposits and withdrawals processed? Most payment methods facilitate instant deposits, but payout times are more varied. Withdrawals processed through credit/debit cards and bank transfers can take multiple days. Cryptocurrencies and e-wallets are faster alternatives.
  • Processing Fees – Players may incur fees when using selected payment methods. Credit cards and bank transfers are the most common. Withdrawal fees are more likely. E-wallets and cryptocurrencies are associated with no-fee payments.

  • Payment Limits – Low deposits and high maximum withdrawals are available. Prepaid cards have smaller limits than credit cards, and many cryptocurrencies have no limits.
  • Availability & Convenience – We recommend options that are available in your country. This is achieved by monitoring government regulations and policies. The majority of traditional casinos accept cards, e-wallets, and bank transfers.
