Pay your phone bill with crypto
Pay any prepaid mobile bill in 150+ countries and settle in crypto. FillUpCoin accepts BTC, ETH, USDT (TRC-20 and ERC-20) and SOL, pushes the top-up to the carrier within minutes, and never asks you to sign up or verify ID. Works for your own line or for someone else's — anywhere in the world.
Which cryptocurrencies can I use?
Bitcoin (BTC) on-chain — the universal choice. Fees depend on current mempool conditions.
Ethereum (ETH) on the mainnet — a bit more expensive on gas but a great choice if you already hold ETH.
Tether (USDT) on TRC-20 (Tron) — our recommendation for small amounts. Fees are a few cents and settlement is near-instant.
Tether (USDT) on ERC-20 (Ethereum) — if your wallet is on Ethereum and you don't want to bridge.
Solana (SOL) — sub-second settlement, sub-cent fees, perfect for topping up a cheap plan.
How crypto phone bill payments work
Choose the destination country and the mobile operator (we support Verizon, T-Mobile, AT&T, Vodafone, Jio, Airtel, MTN, Vivo, Claro, Telcel and 600+ others).
Enter the phone number and the amount — denominations are shown in the local currency so there's no confusion.
Pick your crypto. We show the exact amount to send and a QR code with the destination address. Scan from your wallet.
Once the payment confirms on-chain, the top-up is pushed to the carrier. You get an email receipt. If it's a voucher-only product, the PIN arrives in the same email.
Pay your own phone bill, or someone else's
If it's your own line, enter your number, pay, you're done — the airtime hits the balance within a few minutes.
If it's a family member abroad, give us their number instead of yours. The top-up lands on their phone, in their currency, from your crypto. No remittance app, no border, no form.
If the carrier only sells vouchers (common in Europe for Lebara, Vodafone PIN, Lycamobile PIN and T-Mobile PIN), the PIN is emailed to the address you provide. The recipient dials *100# or opens the carrier app, enters the code, and it credits the balance.

FAQ
Does FillUpCoin take a commission?
The price you see at checkout is final. There's a small spread baked into the quoted crypto amount — comparable to or lower than card processors. No subscription, no monthly fee, no hidden charges.
What's the fastest crypto for small top-ups?
USDT TRC-20 or Solana. Both settle in seconds and cost cents in network fees. For a $10–$30 top-up they're the obvious pick.
Can I pay with a stablecoin instead of a volatile coin?
Yes — USDT on TRC-20 or ERC-20. The invoice is quoted in USDT so there's no exchange-rate risk between invoice time and payment time.
Do you support Lightning Network?
Not currently. We accept Bitcoin on-chain. On-chain confirmations are usually under 10 minutes for a 1-sat/vB fee, which is fine for most top-ups.
