GTBank’s USSD banking code *737# has become one of the most convenient ways for customers to carry out banking transactions—such as checking account balances, transferring funds, buying airtime, or paying bills—without needing internet access. However, there are times when the code might stop working, leading to frustration and confusion.
If you’ve recently asked, “Why is my GTBank USSD code not working?” you’re not alone. This article breaks down the possible reasons and provides practical steps to help you fix the issue quickly.
Common Reasons Why GTBank USSD Code Might Not Work
1. Unlinked or Inactive Phone Number
The most common reason the *737# USSD code fails is that the number you’re dialing from is either not registered with your GTBank account or has become inactive.
Fix:
Ensure you’re using the exact phone number linked to your GTBank account. If you’ve recently changed your SIM card, updated your line, or ported your number to another network, you may need to re-register your number with the bank.
2. Insufficient Network Coverage
Poor or unstable mobile network coverage can prevent USSD codes from executing properly.
Fix:
Move to an area with stronger signal coverage and try again. If the issue persists, switch your phone to airplane mode for a few seconds and switch it back off to refresh your network.
3. Service Downtime or System Maintenance
GTBank or your mobile network provider may be undergoing scheduled maintenance or experiencing temporary service disruptions.
Fix:
Wait a few minutes and try again. You can also check GTBank’s official social media pages or website for announcements regarding any ongoing service outages.
4. Unpaid USSD Access Fee
Some mobile networks in Nigeria now charge users a small fee per USSD transaction (usually ₦6.98). If your airtime balance is zero, the code may not work.
Fix:
Ensure you have at least ₦10 airtime on your line. Try dialing *737# again after recharging.
5. Phone Compatibility Issues
Though rare, some phones—especially older models—might experience glitches running USSD codes.
Fix:
Restart your phone or insert your SIM into a different phone and try dialing the code again.
6. Security Lock or SIM Restrictions
If your SIM has been locked, blacklisted, or deactivated due to prolonged inactivity or security concerns, the USSD code will not work.
Fix:
Contact your mobile network provider to check if your SIM is still active. If it’s been deactivated, you may need to retrieve or replace it.
7. Bank-Specific Restrictions
In some cases, GTBank might restrict your account from using USSD services for security or compliance reasons—especially if suspicious activity has been detected.
Fix:
Visit the nearest GTBank branch or contact GTConnect on 0700-4826-66328 for direct assistance. You may be required to verify your identity.
