Solutions for Not Receiving SMS Verification Codes

If you do not receive the SMS verification code from Tbbit in a timely manner during account operations, it is typically caused by carrier interception, device settings, or international gateway fluctuations. Please follow these steps to troubleshoot:

Step 1: Basic Troubleshooting (Resolves 90% of common issues)

1. Check Spam/Block List: Some mobile security software or system settings may misclassify international system messages as "Spam." Please check your "Spam," "Blocked," or "Junk" SMS folders.

2. Verify Signal Strength and Status: Ensure your device has a stable cellular connection and that Airplane Mode is turned off. Weak signals or network switching can cause delivery failure.

3. Clear Inbox Space: If your SMS storage is full, you will not be able to receive new messages. Please delete redundant messages to free up storage capacity.

Step 2: Advanced Inspection (Carrier and Account Status)

1. Verify Account Balance: Ensure your mobile number is active and not suspended due to an overdue balance or other restrictions to ensure basic communication services are functional.

2. Check International Roaming and Permissions: If you are abroad or using a non-local number, ensure that "International SMS Reception" is enabled and not restricted by your carrier for certain regions.

3. Avoid High-Frequency Requests: Network congestion may cause delivery delays. It is recommended to wait 60-120 seconds after clicking "Send." Frequent requests within a short window may cause your number to be temporarily flagged by the carrier, triggering reception limits.

Step 3: Device Optimization

1. Reset Communication Module: Try toggling Airplane Mode on and off, or restart your phone. This helps reset the connection between your device and the carrier's base station, resolving network-related hangs.

2. Test with Another Device: If possible, insert your SIM card into another mobile device to rule out hardware issues or specific software conflicts on your primary device.
