Buy with Apple Pay purchases on fomo go through Crossmint. When you tap Buy with Apple Pay, you are buying a specific token directly. This is different from depositing to your cash balance with a debit card.
The most common reason a purchase fails is the card linked to your Apple Pay. Only bank-issued debit or credit cards are accepted. Apple Cash, prepaid cards, and virtual cards are not supported.
Some banks block crypto related purchases by default. If your card is being declined and your details are correct, contact your bank to confirm they are not blocking the transaction.
The daily limit for direct token purchases through Apple Pay is 2,500 dollars, which resets at 12 AM EST. If you have reached it, wait until it resets.
If you have made too many attempts in a short period, wait at least one hour before trying again. Closing and reopening the app does not reset the timer.
If the message mentions your country or region, Apple Pay purchases are not available where you are, and retrying will not change that.
In the app you can still try a debit card deposit from the main Deposit screen, unless that too says deposits aren't available in your region. If you already have USDC on another wallet or exchange you can deposit it under Crypto.
If you want to add funds to your cash balance instead of buying a specific token, go to the main Deposit screen in the mobile app and tap Debit. The Deposit cash screen takes Apple Pay where it is available to your account, or your debit card under Details. Either way the funds land in your cash balance as USDC.
