Best Boku Alternatives for Deposits

Q: What is the best alternative to Boku for UK players?

Fonix is the best Boku alternative if you want higher deposit limits and seamless one-tap mobile billing. It supports up to £40 per transaction and works automatically on most UK mobile networks when you're connected to 4G or 5G.

Q: Can I use Siru Mobile with any UK mobile network?

Yes. Siru Mobile is compatible with all major UK networks, including O2, EE, Vodafone, and Three. It works via Payforit infrastructure and requires a quick automated phone call to confirm your deposit.

Q: Is Payforit a payment method or provider?

No. Payforit is not a brand or provider — it's the shared carrier billing framework used by UK mobile operators. Fonix, Siru, and Boku all route their charges through Payforit.

Q: Are there fees when using Fonix or Siru?

Fonix is usually free to use, though some network terms may apply. Siru charges a small service fee, which is clearly shown before you confirm the transaction. Boku is generally free but limited to £30.

Q: Can I still deposit with Fonix or Siru if Boku isn’t listed?

Yes. Many casinos support multiple mobile billing providers behind the scenes. Even if Boku isn’t shown, you may still be able to use Fonix or Siru — especially if the cashier lists options like “Pay by Phone” or “Mobile Billing”.

Many Boku alternatives, such as Siru and Fonix, exist for making casino deposits. If you don’t see the Boku logo at the cashier, other direct carrier billing options are available — all routed through the same Payforit infrastructure used by UK mobile networks.

Top Boku Alternatives for Pay by Mobile Deposits

Below are the two best Boku casino alternatives for mobile players in the UK:

1. Fonix

What it is: Fonix is a newer carrier billing provider used by UK-facing casinos. It’s designed for frictionless deposits via mobile connection (4G/5G).
Why it’s good: Fonix often supports the £40 maximum mobile deposit limit, which is higher than Boku's standard £30.
User experience: On supported networks, Fonix can auto-detect your number without the need to type it in or verify via SMS.
Where it appears: Some mobile-optimised casinos label Fonix as “Mobile Billing” or “Pay by Phone”.

2. Siru Mobile

What it is: Siru is ideal for low-limit mobile deposits starting at £5, making it a favourite for casual players or trial runs.
Why it’s good: Offers deposits as low as £5, which is lower than most other mobile payment methods.
How it works: Confirmation happens through a short automated phone call to your mobile. The amount is then added to your phone bill.
Fees: Siru may apply a small service fee (usually a deposit percentage), which will be displayed before confirmation.

Boku Alternatives AI Summary:

If Boku isn’t available for mobile casino deposits, UK players have strong Fonix and Siru Mobile alternatives. All three use the same Payforit infrastructure, letting you deposit by charging your phone bill or PAYG balance—no bank card needed.

Fonix is ideal for higher deposits (up to £40). It often auto-detects your mobile number for seamless payments and usually doesn’t require SMS confirmation.
Siru Mobile is best for small deposits (as low as £5). It confirms payments via an automated phone call, though it may charge a small service fee.
Payforit is the shared UK billing system powering all these services, supporting O2, EE, Vodafone, and Three.

All options are secure and fast, and your banking details are kept private, making mobile deposits easy and accessible even when Boku isn’t listed.

What Is Payforit?

Payforit is not a payment provider — it’s the underlying billing framework that powers all direct carrier billing in the UK. Whether you see Boku, Fonix or Siru on a casino site, the charge is processed across Payforit’s shared infrastructure.

All major UK networks — including O2, EE, Vodafone, and Three — support Payforit, which ensures consistent charging through your mobile account. These providers can route the deposit straight to your phone bill without needing cards or banking details.

Which Boku Alternatives Should You Use?

Fonix is the top choice if you want higher deposit limits and a seamless mobile experience. It offers up to £40 and often doesn’t require SMS confirmation. For small test deposits or casual play, Siru Mobile is ideal, especially if you want to deposit just £5 to try a site.

All three options—Boku, Fonix, and Siru—rely on the same UK mobile infrastructure and are equally secure. They use your mobile network to confirm charges and avoid sharing card details.

Final Thoughts on Boku Alternatives

If Boku isn’t available, don’t assume mobile billing is off the table. UK casinos increasingly support Fonix and Siru as reliable alternatives. Whether you're depositing £5 or £40, there's a Payforit-powered method that fits your needs.
