Frequently asked questions
Can I top up a mobile number in another country with crypto?
Yes. CardsRelay supports international mobile top-ups in 170+ countries using 14 cryptocurrencies. Enter the full number with country code, select the operator, choose an amount, and pay with crypto.
What is the difference between airtime and mobile data top-up?
Airtime (also called call credit or voice credit) lets you make calls and send SMS. Data top-ups add mobile internet allowance. Both are available on CardsRelay depending on the operator and country.
How long does a mobile top-up take after payment?
Most top-ups complete within seconds to a few minutes of payment confirmation. Timing depends on the mobile operator and network. We never guarantee instant delivery because it varies by operator.
Can I send airtime to Nigeria with Bitcoin?
Yes. CardsRelay supports MTN Nigeria, Airtel Nigeria, Glo, and 9mobile. Select the Nigerian operator, enter the phone number, pay with Bitcoin, and airtime credit is sent to the handset.
Can I recharge a phone in India with USDT?
Yes. Airtel, Jio, Vi (Vodafone Idea) and other Indian operators are supported. Pay with USDT TRC20 for fast, low-fee confirmation.
Do I need the recipient to do anything to receive the top-up?
No. Mobile credit is sent directly to the phone number by the operator. The recipient does not need an app, account, or internet connection.
