Pay by Mobile Casino: Boku Deposit Limits

Pay-by-mobile Boku casino deposits offer as easy way for UK players to fund their casino accounts. Boku deposit limits are a cap enforced by UK mobile operators.
In this article, we’ll explain pay by mobile casino Boku deposit limits in the UK. We will also break down the caps for each major network (EE, O2, Vodafone, and Three).
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.
- Carrier Credit Risk: When you deposit via Boku, the mobile network is fronting that money to the casino on your behalf. The deposit amount gets added to your phone bill (if you’re on a monthly contract) or deducted from your airtime (if you’re on PAYG). In effect, the carrier is extending you a line of credit until you pay your phone bill.
- Payforit Scheme Rules: In the UK, pay-by-phone transactions (whether through Boku or other intermediaries) fall under the Payforit umbrella. This is a set of guidelines established by mobile networks and regulated by the Phone-paid Services Authority.
- Regulatory Framework: The Phone-paid Services Authority (PSA) and other regulators oversee carrier billing services. They mandate certain protections for consumers. The low Boku limits can be seen as part of the responsible gambling and consumer protection framework in the UK.
- Preventing Problem Gambling: Although the primary motivation is financial risk, an added benefit is that these limits naturally curb how much you can gamble via your phone in a short period. £30 a day is a modest amount, so using Boku inherently encourages budgeting.
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.
Casino-Level Boku Limits and Variations
While the mobile networks set the overarching limits for Boku transactions. Individual online casinos can impose their own stricter limits or policies for pay-by-mobile deposits. 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:
- Lower Site-Imposed Caps: A casino could set a lower daily or monthly cap on Boku deposits than the network allows. A casino site might only allow £20 per day or £100 per month via Boku. The carrier would technically permit up to £30/day or £240/month.
- Minimum Deposit Requirements: Casinos often set a minimum deposit amount for each payment method. For Boku, this minimum can vary by site: £5, £10, or £15 are common thresholds. Not all casinos allow micro-deposits like £1 or £3 via Boku, even if technically Boku might support very small charges.
- Fees and Restrictions by Casino: Some online casinos impose a fee for using Boku (to offset the high transaction cost charged by mobile billing providers).
- Account Age and Verification: A casino might require your account to be verified or of a certain age before allowing pay-by-phone deposits above a very low amount.
- Affordability and Responsible Gambling Controls: UK casinos are increasingly mindful of affordability checks and gambling limits mandated by the UK Gambling Commission.
How to Check and Manage Your Boku Deposit Limits
- Monitor Your Mobile Billing: Your mobile network will keep track of how much you’ve charged to your bill. You can usually see “Carrier Billing” or “Payforit” charges in your monthly bill breakdown or in your network’s account app.
- Network Notifications: In many cases, if you try to exceed a limit, the transaction will simply be declined. Boku transactions typically trigger an SMS confirmation process.
- Using Network Tools to Adjust Limits: You cannot manually raise the strict Boku limits beyond £30/day as these are set by the carrier for all users.
- Casino Account Limits: Use the responsible gambling tools in your casino account to set your own deposit limits.
- Check with Customer Support: If you’re unsure about how much of your Boku allowance is used or remaining, you can reach out to either the casino or your mobile network’s customer support.
