Send prepaid mobile credit to any phone in 150+ countries and pay in Bitcoin. FillUpCoin takes your BTC on-chain payment and pushes the top-up straight to the carrier within minutes — no bank card, no account signup, no KYC. The sender's location doesn't matter: load airtime home from anywhere in the world.
Pick the destination country, pick the mobile operator, enter the phone number and the amount you want to send. Add an email for the receipt.
At checkout we show a Bitcoin invoice — a BTC address and the exact amount quoted at the live rate. Send the payment from any wallet (Bitcoin Core, Trust Wallet, Electrum, hardware wallet — anything).
As soon as the Bitcoin transaction confirms, we push the top-up to the carrier. In most cases the airtime lands on the number within five minutes of the first confirmation.
Direct refills credit the balance on the number instantly. For voucher-only carriers (Lebara PIN, Vodafone PIN, T-Mobile PIN and so on) the voucher code arrives by email — the recipient enters it on the carrier's own top-up page.
No bank in the chain. If you live in a country with strict capital controls, or you don't want a card payment on your statement, Bitcoin lets you send airtime to a prepaid number anywhere, from anywhere.
Family and friends abroad. Topping up a parent's phone in Nigeria or India from the US used to mean Western Union or a specialised remittance app. With Bitcoin plus FillUpCoin, you send the BTC transaction and the airtime shows up on their phone, in their currency, in minutes.
No account creation. Guest checkout — we only need an email for the receipt. No ID, no verification, no credit check.
Fully refundable on failure. If the carrier rejects the delivery (wrong number, carrier outage, product discontinued), we refund the exact BTC amount of your invoice. The refund is sent back to the address you paid from.
Over 600 carriers across 150+ countries — covering the big networks (Verizon, T-Mobile, AT&T, Vodafone, O2, EE, Three, Jio, Airtel, MTN, Vivo, Claro, Telcel) and the local prepaid brands (giffgaff, Mint Mobile, Lycamobile, Lebara, ALDI TALK, giffgaff, Safaricom, Smart, Globe, Jazz, Zong, and many more).
You can also pay with Ethereum, USDT (TRC-20 or ERC-20) and Solana — pick whatever has the lowest network fee at the time.
You never share ID or payment card details. We only ask for an email so we can send you the receipt and the voucher PIN if applicable. The Bitcoin network is public — anyone can see the invoice address on-chain, but it's not tied to any identity on our side.
Usually under 5 minutes end-to-end. The on-chain confirmation accounts for most of that; the carrier side is typically under a minute.
The invoice is quoted and locked for 20 minutes. If BTC moves inside that window your invoice amount doesn't change. If you underpay, we top up the balance ourselves or refund — contact support with the TXID.
Yes. That's the whole point. Pay the invoice from your wallet, the airtime lands on the destination number, wherever it is.
