However, Pay by Mobile does not identical to paying using Google Pay or Apple Pay (which typically uses your credit card) It is not like sending the bank transfer via a mobile device. It’s a particular billing procedure that relies on payments through your smartphone’s network and it is a payment aggregator.

It generally comes with lower limits however it may have high effective costs however, it also comes with some restrictions on withdrawals. Understanding those constraints upfront is the best way to avoid frustration.
The UK context: how regulation influences payment methods
In the UK betting on online casinos is controlled and usually is subject to strict supervision.
Age checks (18+)
Verification of identity
Anti-money-laundering (AML) processes
Transparent terms used for deposits and withdrawals
Tools for responsible gambling and surveillance
Even though a payment method like Pay by Mobile might look «simple,» regulated operators usually handle it with additional cautiousness. Because carrier billing could increase the risk of fraud in areas like:
Fraud and account takeovers (especially through SIM swap)
Billing complaints and disputes
The impulse to spend (payments may feel «too simple»)
Complexity of payment routes (carrier + retailer + aggregator)
As a result, Pay by Mobile could be available only for a few users and not others, and it may require stricter limits or extra checks.
How Pay via Mobile works (simple step-by-step)
While different checkout flows exist, carrier billing usually follows the same format:
Select Pay by Mobile or Carrier Payment in order to deposit funds.
Make sure you enter the # on your mobile (or confirm your provider instantly)
Receive an OTP / confirmation (often via SMS)
Approve the payment
The deposit is credited, and the cost is:
You can add it to you month-long phone bill (postpaid) in addition to your monthly phone bill
taken from your deducted from your (prepaid)
In the background there are typically three different parties at play:
Operator/merchant (the website that receives payment)
A payment aggregator (specialises in carrier billing connections)
The mobile service you use (the carrier which bills you)
Because of the involvement of multiple parties Issues can arise at multiple points — networks-level blocks, aggregator check, merchant rules, or verification steps.
Postpaid vs prepaid: why your plan matters
Pay by mobile behaves differently dependent on the device you’re using:
Postpaid (monthly bill):
It is then added onto the total
You may have higher limits based on billing history
Certain networks place restrictions on categories
Prepaid (pay-as-you-go credit):
The amount is subtracted from the balance you have available
Failure to pay for a loan occurs if you don’t have sufficient credit
Certain types of billing to pay-per-use lines
In general speaking, carrier billing is typically more reliable with stable postpaid accounts and a steady payment history, however there is no guarantee and the policies of individual carriers may differ.
A withdrawal vs. a deposit: the biggest source of confusion
Carrier billing is generally a bank deposit. This is a key limitation that consumers must be aware of.
Deposits (adding cash)
Carrier billing allows you so that you can collect money from the balance on your mobile phone or bill. Deposits are quick with minimal steps once your mobile number has been confirmed.
Withdrawals (receiving money)
A phone bill isn’t an ordinary «receiving account.» Many systems aren’t built to allow money «back» to your phone bill with a straightforward method. So, many companies route withdrawals via other ways, including:
Bank transfer
debit card
or an ewallet compatible with the system that can pay for payouts
That doesn’t necessarily mean withdrawals are impossible — it means Pay by Mobile typically isn’t going to be the preferred method of withdrawal even if it’s a possibility for deposits.
Things to be aware of prior depositing via Pay by SMS:
Which withdrawal methods are compatible for your account?
Are identity verifications required prior withdrawal?
Are there minimum payout limits?
Are there timelines or «pending» processing window?
These terms will help you avoid the possibility of surprises later.
Common deposit limits: what are they? Pay by Mobile amounts are usually small
Carrier billing usually comes with less caps than bank or card deposits. Limits can be applied on various levels:
Carrier-level caps (daily/weekly/monthly)
Aggregator-level caps (risk scoring)
Merchant-level caps (operator regulation)
Account-level caps (new restrictions for customers the status of verification)
The reason the limits are lower:
carrier billing was specifically designed for micro-transactions (apps or subscriptions),
The risk of dispute or fraud can be greater,
and refund workflows can be a bit complicated.
Thus, as a result, by Mobile often suits small «test» transactions better than regular large payments.
Effective costs and fees: where does the «extra» money is spent
The process of billing for carriers can be more expensive than card transactions because both the aggregator and carrier take part. Based on the setting, that cost could appear as:
a clearly-defined service charge at checkout
An «effective cost» (you must pay X but you get slightly less credit)
more expensive operating-side costs, which directly impact terms
You should always check the screen that confirms your final confirmation:
you will be charged the exact amount that was charged
the existence of a particular fee line
This is the most popular currency (GBP preferentially for UK users)
and that the amount you deposit matches your expectation
If something appears unclearparticularly merchant names that aren’t on the websitedo a pause before you verify.
Why Pay by Mobile deposits fail? Common causes in the UK
