How Boku casino deposits work, and the UK phone bill limits

What a Boku casino deposit is, and what it is not

The mechanic takes one sentence. A player asks to deposit, confirms against a mobile number rather than a card, and the amount is added to that mobile account. Contract customers find it on the next bill. Pay-as-you-go customers watch their credit fall immediately. No card details are entered.

What that description leaves out is who Boku is. Carrier billing is the route; Boku is a business operating on it, and the two words get used as synonyms on nearly every page that mentions either. The distinction is not pedantry. Which company handled a given Boku casino deposit decides which regulator is involved and which rulebook applies to it. Anyone asking how Boku casino deposits work is therefore asking about two companies rather than one, and the answer changes depending on which of them sat in the middle of the transaction.

The route also runs one way. A charge placed on a mobile account cannot be reversed back down the same path as a withdrawal, so anyone depositing this way is picking a deposit method and a separate withdrawal method at the same time, whether or not the cashier page makes that obvious at the point of choosing.

Two companies share the Boku name on a phone bill

Boku's own group disclosure splits the two functions across two British companies, and it is specific enough that the effect is worth stating rather than paraphrasing.

Boku Network Services UK Limited, company number 05044979, is the one described as providing direct carrier billing, which the same disclosure also calls premium rate services. Complaints about that activity escalate to Ofcom rather than to a financial regulator.

Boku Account Services UK Limited, company number 06169107, is the authorised one. It holds FRN 900030 as an Authorised Electronic Money Institution under the Electronic Money Regulations 2011, effective 24 May 2018, with payment-initiation and account-information permissions under the Payment Services Regulations 2017. It also states that it does not provide direct carrier billing or premium rate services in the United Kingdom.

The split is not only what the companies say about themselves. Companies House classifies the two differently as well: 05044979 under other telecommunications activities, 06169107 under financial intermediation not elsewhere classified. One is filed as a telecoms business and the other as a financial one, which is what the disclosure describes, recorded independently.

Read all of that together and a great deal of published writing about this method has a problem. The reference number quoted as evidence that a phone bill deposit sits inside financial regulation belongs to the company that says it does not offer the phone bill product. The same confusion runs through the wider label, which is the subject of how pay by phone casino deposits work in more depth.

That is checkable rather than merely assertable, which matters on a point this load-bearing. The FCA publishes its registers as downloadable files as well as through the search page, and on the e-money file as published at the close of business on 16 August 2026, FRN 900030 resolves to Boku Account Services UK Ltd with the status Authorised Electronic Money Institution. Boku Network Services UK Limited appears on neither that file nor the list of firms holding payment-services permissions.

None of which says either company has done anything wrong, and it should not be read that way. One group running a telecoms business and a payments business as separate companies is ordinary structure, and keeping them separate is usually the point of doing it. What it does mean is that a brand on a cashier button is not a regulatory status, and that quoting a group's best-regulated entity as though the permission covered everything the group does is an error a register lookup settles in about a minute.

Boku casino deposit limits UK players actually meet

Two ceilings are in play and they come from different places, which is why published figures disagree with each other so freely. One is written into the regulations. The other is set commercially, by the mobile networks and by the cashier, and it is usually the lower of the two.

The statutory pair sits in Schedule 1, Part 2, paragraph 2(l) of the Payment Services Regulations 2017. The value of any single payment transaction must not exceed £40, and the cumulative value of payment transactions for an individual subscriber in a month must not exceed £240. Both conditions have to hold at once.

The unit is the part most often stated wrongly. The ceiling attaches to an individual subscriber, and the guidance treats each telephone number or SIM as a separate subscriber rather than each person. Two SIMs are two subscribers. Someone carrying a work phone and a personal phone is counted twice, which is a higher ceiling than the per-person figure almost every page describes.

Against the statutory pair, the Boku casino deposit limits UK cashiers actually display are frequently lower. Around £30 for a single deposit is the figure most widely reported, and networks apply their own daily and monthly ceilings that move with account type and standing. None of that is published as a rule anywhere, which is worth saying plainly: the sources quoting £30 agree on the per-transaction figure and contradict each other on the daily one. Those are commercial limits. They can be changed by whoever set them, and a page presenting them as the legal position has quietly swapped a business rule for a regulation.

The two ceilings are also enforced by different parties, which is the part that decides which one a person ever notices. The Boku casino deposit limits UK players meet at the cashier are applied by the network at the moment of the transaction, so they bite directly and immediately. The statutory pair binds the businesses in the chain instead. A player never sees it enforced at all, and would have no way of telling whether it had been.

Where the phone bill route leaves a UK deposit

The £40 and £240 figures are not general consumer protections, and reading them as though they were is what makes them look more important than they are. They are conditions attached to an exclusion, and that exclusion is the reason carrier billing can exist at all without the mobile network being regulated as a payment business. Part 2 of the schedule they sit in is headed activities which do not constitute payment services.

The exclusion is limited by what is being bought. It reaches digital content and voice-based services, tickets, and donations to charity. That is the list. A gambling deposit is not on it, and staying under £40 does not put it there, because the value caps are a further condition rather than the first one.

Which makes the limits question smaller than it looks from outside. A deposit that clears both ceilings with room to spare sits in exactly the same position as one that breaches them, because the exclusion has already failed on what kind of transaction it is. A rail whose provider holds a permission of its own never has to make that argument, and the prepaid voucher route is the clearest example of the difference.

One thing did change recently, and it changed the address rather than the substance. Premium rate services in the UK were regulated by the Phone-paid Services Authority until the Regulation of Premium Rate Services Order 2024 came into force on 1 February 2025, at which point Ofcom took the function over directly. A complaint about the carrier billing side of a phone bill charge now goes to Ofcom rather than to a separate body.

That leaves one question this page cannot close. The e-money company disclaims the carrier billing product; the carrier billing company appears on neither register checked, which is what an arrangement resting on the exclusion rather than on a permission would look like; and the exclusion does not reach a gambling deposit on subject matter. Nothing in the published group disclosure says which permission a UK gambling deposit charged to a phone bill is meant to run under. The disclosure is under no obligation to say. It simply means the answer is not on the public record, and deriving one from the shape of the group would be a guess wearing the clothes of a finding.

What a player can identify from the transaction record

The route leaves different evidence from a card deposit. A contract customer sees the charge on the mobile bill; a pay-as-you-go customer sees credit reduced. Neither record is a card statement, and neither creates a balance the gambling business can credit later as a withdrawal.

The mobile number used for confirmation is also the unit closest to the statutory subscriber limits. That does not tell a player which company sat at every point in the chain, but it does show why changing casino accounts would not reset a ceiling attached to the SIM or telephone number.

A cashier label cannot identify which Boku entity performed a particular step. The useful distinction comes from the contractual description and the record of the charge: carrier billing belongs to the network-services side, while an e-money account or payment-initiation service belongs to the separately authorised company. The brand alone cannot carry that answer.
