Boku Deposit Limits on UK Mobile Networks

When using Boku to deposit at an online casino, there are firm limits on how much you can charge to your phone. These limits are set in partnership with the UK mobile networks to prevent overspending. All major UK carriers enforce similar Boku deposit caps, typically allowing only small transactions.

Below is a breakdown of the standard Boku deposit limits – per single transaction, per 24-hour period, and per 30-day period – for each mobile network that supports this service:

As shown above, the typical maximum you can deposit via Boku is £30 in one go, and you can only spend up to £30 in total within a 24-hour period​. There is a cumulative monthly limit of roughly £240 that applies to Boku deposits.

All the major networks, such as EE, O2, Vodafone, and Three, adhere to these standard limits through the UK’s carrier billing system.

EE Deposit Limits

EE customers using Boku are limited to £30 per deposit, with a maximum of £30 per 24 hours charged to the bill. There is a £240 per month deposit limit in total. These caps are applied by EE for both pay-monthly and pay-as-you-go users (for pay-as-you-go, you must have enough credit available for the deposit).

Since BT Mobile operates on EE’s network, BT customers have the same effective limits. EE’s system will decline further Boku charges once you hit the daily or monthly cap.

O2 Deposit Limits

For O2 users, the standard Boku limit is £30 per transaction and per day, with a £240 monthly cap. O2 was one of the original supporters of Payforit, and it enforces the same default ceiling on pay-by-phone casino payments. All O2 mobile customers (including those on giffgaff or Tesco Mobile, which use O2’s network, as well as Virgin Mobile now merged with O2) are subject to these Boku limits.

Vodafone Deposit Limits

Vodafone subscribers also face a £30 max per Boku deposit, £30 per day, and about £240 per month as the limit for pay by mobile casino transactions. Boku deposits are supported by Vodafonethrough the Payforit framework just like the other operators. This means whether you’re on Vodafone’s main network or an MVNO partner using Vodafone’s network, the same cap on charges usually applies. If you try to exceed £30 in one day on Vodafone via Boku, the payment will be declined and you’ll be notified that you’ve hit the spending limit.

Three Deposit Limits

Customers on Three (3) have the identical Boku deposit restrictions: £30 per single deposit, up to £30 total per day, and up to £240 in a month charged to their phone bill via Boku. Three will block any Boku transactions beyond the daily or monthly cap. For example, if you’ve already done two £15 deposits today (totalling £30), a third deposit on that same day will be refused. Three users should therefore plan their Boku casino top-ups with the knowledge that £30 is the daily maximum.

Why Are These Boku Deposit Limits in Place?

Boku deposit limits might seem low, but there are important reasons for their existence. These limits are primarily set for credit risk management and consumer protection.

Boku’s deposit caps exist to protect both the mobile networks and the consumer. The carriers avoid large unpaid bills, and players are shielded from accumulating severe gambling debt on a phone bill. The system is intentionally designed for low-value transactions. As convenient as it is, you won’t be using Boku to deposit hundreds of pounds in one go, and that’s by design.

It’s important to understand that the carrier limits (e.g. £30/day) are a maximum ceiling. Some casino sites choose to set the bar lower for various reasons. Here are some ways Boku deposit limits may differ at the casino level:
