About O2 in United Kingdom
O2 is one of the 9 prepaid networks operating in United Kingdom, with the dial code +44. Refills are denominated in GBP and settle on the carrier under 60 seconds after our payment confirms on chain.
You don't need a O2 account, the United Kingdom MyCarrier app, a local bank or any in-store kiosk — just the phone number and the crypto. The credit shows up on the SIM exactly the same way as if you'd topped it up at a corner store.
O2 mobile top-up · FAQ
Can I top up O2 with Bitcoin?
Yes. Pay in Bitcoin (BTC), Monero (XMR), Ethereum (ETH), USDT (TRC/ERC/SOL), Litecoin (LTC), Bitcoin Cash (BCH), Solana (SOL), Dogecoin (DOGE), Dash (DASH), Tron (TRX) or BNB. The O2 line in United Kingdom gets credited within minutes of your deposit confirming on chain.
How fast does the O2 credit land?
Carrier-side, O2 typically posts the credit within 30 seconds of our settlement message. End-to-end (you click pay → SIM has credit) it's usually 1-3 minutes on fast chains (LTC, TRX, SOL), up to 10 minutes on slower ones (BTC).
What's the cheapest crypto for a O2 refill?
For small refills (under $50 USD-equivalent), USDT-TRC20, Tron (TRX), Litecoin (LTC) or Solana (SOL) keep network fees to single cents. Bitcoin works fine but BTC fees can be disproportionate for small top-ups — pick a cheaper chain instead.
Do I need a O2 or United Kingdom account?
No. We talk to O2 on the back end with the phone number alone. No MyO2 portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.
Will O2 or the recipient see I paid in crypto?
No. O2 sees a routine top-up at the local face value (GBP). The recipient sees the new balance on their SIM. Neither sees the funding source, your email, or any other payment metadata. From the SIM's side it's identical to a corner-store refill.
