What SMS Verification Means for FUPS Card
FUPS is a Turkish prepaid card service. When making online payments that support 3D Secure (Verified by Visa / Mastercard SecureCode), the system sends a one-time password (OTP) to the phone number linked to your account.
The error occurs when this code is not delivered or is not accepted — causing the payment to fail. This is particularly common for users with foreign SIM cards.
Why FUPS SMS Verification Fails
1. Foreign phone number FUPS, like many Turkish fintech services, is optimized for Turkish numbers (+90). SMS messages to numbers in other countries may not be delivered, may arrive with significant delay, or may be blocked by the SMS gateway.
2. Number not linked or outdated If you provided one number at registration but have since changed it, OTPs are still being sent to the old number. Changing your number requires re-verification.
3. SMS delivery delay International SMS messages often arrive with a 5–15 minute delay. If you enter the code after it has expired, it will be rejected even if it eventually arrives.
4. Phone in roaming If your phone is in roaming, incoming SMS may not be delivered depending on your carrier and the country you are in.
5. Merchant requires 3DS Some websites do not offer an option to pay without 3DS verification. If the SMS doesn't arrive, the transaction is irrevocably declined.
6. VoIP number rejected If you registered with a VoIP number (such as Google Voice or Skype), FUPS may reject it for OTP delivery as a security measure.
Step-by-Step Fix
Step 1. Confirm the phone number on your account is current. Log into your FUPS account and check the linked phone number. If it is outdated, update it following the service's instructions.
Step 2. Use a real SIM card, not VoIP. If your number is virtual (Google Voice, Skype, etc.), it will not work for SMS verification. Use a physical SIM card.
Step 3. Wait a few minutes. International SMS can be delayed. Do not enter the code immediately — wait up to 10 minutes, then check your phone.
Step 4. Request the SMS again. The 3DS verification page usually has a "Resend code" button. Use it if the first code never arrived.
Step 5. Check for SMS filters with your carrier. Your mobile carrier may be blocking SMS from foreign short codes. Contact your carrier to check for such a filter.
Step 6. Contact FUPS support. If the issue is systemic, contact support and ask about an alternative verification method or adding a different phone number.
