About Viettel in Vietnam
Viettel is one of the 4 prepaid networks operating in Vietnam, with the dial code +84. Refills are denominated in VND and settle on the carrier under 60 seconds after our payment confirms on chain.
You don't need a Viettel account, the Vietnam 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.
Viettel mobile top-up · FAQ
Can I top up Viettel 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 Viettel line in Vietnam gets credited within minutes of your deposit confirming on chain.
How fast does the Viettel credit land?
Carrier-side, Viettel 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 Viettel 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 Viettel or Vietnam account?
No. We talk to Viettel on the back end with the phone number alone. No MyViettel portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.
Will Viettel or the recipient see I paid in crypto?
No. Viettel sees a routine top-up at the local face value (VND). 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.
