A1 is one of Bulgaria’s biggest mobile operators, the network many people still think of by its old name, Mtel. In a handful of Bulgarian casino cashiers it shows up as a way to pay straight from your phone account.
That makes it one of the simplest deposit options there is. No card, no bank login, just a confirmation on your phone and the amount lands on your monthly bill or comes off your prepaid credit.
Below are the casinos tagged with A1, followed by how phone payments work, why they suit small deposits only and what the Bulgarian rules mean for players.

Can you deposit at online casinos with A1?
At some Bulgarian casinos, yes. Where an operator offers mobile payments through A1, you choose it in the cashier, confirm with your phone number and a code, and the deposit is charged to your A1 bill or prepaid balance. Limits are low and winnings cannot be paid back to your phone account, so you need a bank account or another method for withdrawals.
The company behind A1 Bulgaria started out in the mid 1990s and became a household name as Mtel. It has been part of the Austrian A1 Telekom Austria Group since 2005, and in May 2018 the Bulgarian business switched to the A1 brand.
A1 is one of the three big mobile networks in Bulgaria, alongside Vivacom and Yettel, so a large share of Bulgarian players carry an A1 SIM. Today it offers fixed internet and TV alongside its mobile network. For casino players the relevant part is much narrower: the ability to charge small payments to a phone account, which some local operators have built into their cashiers.
Choose the A1 or mobile payment option, enter the amount and type in your phone number. You will receive a code by text message to confirm that the payment really comes from you.
Contract customers see the deposit on their next monthly bill. Prepaid customers have it deducted from their credit straight away, so the balance needs to cover the full amount.
Phone payments were designed for apps, tickets and small digital purchases, not for large transfers. Operators set low caps per payment and per month, and many contracts let the account holder switch third party charges off entirely.
That has an upside for players. A phone payment is a natural brake: you cannot accidentally deposit a large sum, and the total shows up in one place at the end of the month. The downside is that it is useless for anyone who wants to move serious money, and it may not be available at all on business or family plans.
A mobile account cannot receive casino winnings. When you win, the casino will pay you by bank transfer or another method that supports payouts, usually to an account in your own name in Bulgaria.
It also helps to know that some casinos treat phone payments as a deposit method with extra conditions, for example excluding them from certain bonuses or asking for a minimum amount of play before a withdrawal. Read the bonus terms and the banking page so there are no surprises.
Plan that from the start. Complete the identity checks when you register, add your IBAN, and the first withdrawal goes far more smoothly than if you try to sort it out after a big win.
Bulgaria licenses online gambling, and the National Revenue Agency acts as the regulator and enforcement body. Only operators with a Bulgarian licence may legally offer games to players in the country.
Since 18 May 2024 most gambling advertising has been banned on Bulgarian TV, radio, websites, print and public places. What remains has to carry a clear warning that gambling carries a risk of addiction.
Licensed sites are the ones offering local payment options like A1. Offshore sites that target Bulgaria without a licence fall outside Bulgarian protection.

For a quick top up of EUR 10 or EUR 20 at a licensed Bulgarian site, paying through A1 is about as easy as it gets, and the low limits keep spending in check.

At some licensed Bulgarian casinos, yes. The deposit is charged to your A1 bill or prepaid credit.
