Your USD wallet can be used for eligible eSIM, international airtime, and gift purchases. Available funding methods, limits, and fees are shown in the app before you confirm a deposit.
- Sign in to the MobileTopup app and open your USD wallet.
- Select Add USD funds.
- Choose an amount. This is the amount your wallet will receive; any applicable fee is shown before payment.
- Select one of the payment methods currently available to your account and complete the checkout steps.
Adding funds with USDC
If the app presents USDC instructions, send the exact displayed amount to the displayed address using only one of the networks shown for that deposit. Your wallet is credited after the transfer confirms on-chain.
Do not reuse an old address, amount, or network from a previous deposit. If the wallet still shows as pending after the network confirmation, keep the transaction details and contact support.
For USDC payment fees and checkout availability, see USDC payments and supported networks.
