How to top up Unefon Mexico with crypto

Unefon is a prepaid mobile carrier in Mexico available on the Unefon Mexico page on Cryptorefills. It accepts USDT, USDC, SOL, BTC on Lightning, and other coins. Enter the Mexican number in international format (+52 followed by the ten-digit subscriber number), select the denomination, pay with crypto, and the credit is applied to the number within minutes. A delivery email is the only requirement.

How to enter a Mexican mobile number correctly

Mexican mobile numbers are ten digits long. The standard international format is +52 followed by the ten digits, giving twelve digits in total after the plus sign. Some older systems use +52 1 before the ten digits, a legacy format from before Mexico unified its mobile numbering in 2020. At Cryptorefills checkout, use +52 followed directly by the ten-digit number with no "1" in between.

Mexican numbers are sometimes written with a local area code and subscriber digits , for example, (55) XXXX XXXX for Mexico City. The ten-digit format is the area code plus the subscriber number without separators. A Mexico City number written locally as (55) 1234 5678 becomes +52 55 1234 5678, or +525512345678 without spaces.

Which crypto to use for Unefon top-ups

USDT on Tron carries fees below $0.01 and is the most cost-effective option for small top-ups. BTC on Lightning settles near-instantly at the same cost. USDC on Solana is practical for Solana wallet holders. For amounts above $30, the fee difference between networks becomes less significant. Ethereum mainnet is not efficient for small top-up amounts given gas costs.
