About Ultra Mobile in United States
Ultra Mobile is one of the 15 prepaid networks operating in United States, with the dial code +1. Refills are denominated in USD and settle on the carrier under 60 seconds after our payment confirms on chain.
You don't need a Ultra Mobile account, the United States 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.
Ultra Mobile mobile top-up · FAQ
Can I top up Ultra Mobile 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 Ultra Mobile line in United States gets credited within minutes of your deposit confirming on chain.
How fast does the Ultra Mobile credit land?
Carrier-side, Ultra Mobile 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 Ultra Mobile 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 Ultra Mobile or United States account?
No. We talk to Ultra Mobile on the back end with the phone number alone. No MyUltra Mobile portal login, no SIM swap, no local bank, no in-store kiosk. Just enter the number, pick the amount, pay in crypto.
Will Ultra Mobile or the recipient see I paid in crypto?
No. Ultra Mobile sees a routine top-up at the local face value (USD). 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.
