The confirmation of a deposit on the Fiat Wallet requires a confirmation with a PIN. You will receive it by SMS or call. There is no alternative to this option.
If you do not receive the PIN when making the deposit, there may be a variety of reasons. Please make sure first of all that you have entered the correct mobile number with the correct country code in your account.
Also, note that unfortunately we only accept most European mobile phone numbers. Please also make sure that you have a good connection to the mobile network. Please also activate roaming to establish a connection to the mobile network abroad.
