What is Boku and How Does it Work for Betting?
Boku is a mobile payment service that allows users to fund accounts, including gambling sites, using a mobile phone number. All transactions are free and protected on both sides, secured by Boku and your chosen sportsbook app.
How does Boku work in betting? Add Boku to your preferred payment methods in the profile section of your gambling account. Add the amount to deposit, and it appears instantly. It’s as easy as that.
A Simple Explanation of “Pay by Mobile”
It’s important to know that Boku isn’t an e-wallet, but a carrier billing service that handles a deposit by charging it to your mobile phone provider using one of the following options:
Pay monthly customers: The deposit amount is added to your next bill.
Pay-as-you-go customers: The funds are taken from your available credit.
The Main Advantages of Using Boku
Here are my three favourite things about using Boku as a modern payment method for online gambling.
- It’s incredibly fast and user-friendly, appealing to both experienced and new gamblers. All you need is a mobile number and to confirm the SMS.
- The fact that you don’t need to share your most sensitive information, such as your bank details, helps keep you safe and offers peace of mind.
- Boku has a daily deposit limit of £30 and is strict, helping bettors keep a tight hold of their online betting budget and bankroll.
How to Deposit with Boku (and What About Withdrawals?)
To make life even easier for my fellow gamblers, I’ve provided a step-by-step guide on how to fund your betting account using Boku.
Making a Deposit
- Visit your chosen betting app and enter your login details.
- Click on your profile and select deposits. Hit the Boku option from the list.
- Enter the amount you’d like to deposit, starting at £5.
- Input your mobile number.
- You’ll get a text message asking you to confirm the transaction.
- The amount is charged, and the funds appear in your betting balance.
The Crucial Limitation: Boku Cannot Be Used for Withdrawals
Now you know just how easy it is to deposit funds to your betting account using Boku, you can give it a try when next gambling on football, horse racing, tennis, and other favourites.
When dealing with Boku, please know that you cannot withdraw winnings back to your mobile bill. That means if you’re using Boku to cover deposits, you must register an alternative for withdrawing your profits. That could be an e-wallet or a debit card.
The Flashscore Advantage: Making Your Small Stakes Smart
When building your gambling experience or sticking to a budget, it’s crucial to study the stats and keep your stakes small. Flashscore has everything you need to research a bet, including the latest stats, results, form, league standings, and head-to-head scores. You must also keep your stakes modest, and Boku is ideal for helping you achieve this.
Boku is perfect for casual gamblers as you can deposit between £5 and £30 per day. But betting small doesn’t mean you will win small. Use Flashscore to find the bets with the best odds, including first goalscorer picks in Premier League football. Here’s a practical example:
You deposit £5 using Boku to your chosen gambling account to bet on the next Premier League showdown broadcast live on television. You know guessing is a shortcut to losing, so you use the Flashscore app to gather the most relevant stats and trends. You notice a player has scored in each of his last three meetings against the opposition, and bet him to score anytime in the renewal. Flashscore helps you turn a small bet into a smart bet.
