Not receiving SMS verification on your smartphone? The complete guide to solutions

The issue of not receiving SMS verification codes is a common problem experienced by many users. When security authentication cannot be received, accessing your account becomes difficult. This guide provides practical steps to resolve the situation where SMS messages are not coming through.

First, basic checks: verify your inbox and communication environment

If you do not receive the SMS verification code, the first thing to check is the status of your smartphone’s inbox and your communication environment. If your inbox is full, new SMS messages cannot be received. Clear out your inbox and try receiving the SMS again.

Next, restart your smartphone and ensure that your mobile carrier’s signal reception is stable. Weak or unstable network signals can cause SMS messages not to arrive. Turning airplane mode on and off to reset the connection can also be effective.

Check if security settings are blocking SMS

Make sure that security software or security apps installed on your smartphone are not blocking the authentication code in the background. If such settings are enabled, SMS messages may not be received.

For important procedures such as withdrawal requests, consider temporarily disabling security app settings or adding the number to a whitelist. Then, try requesting the authentication code again.

Check for hardware issues

Problems with the SIM card connection can also be a cause. If you have a dual SIM smartphone, try swapping the SIM card to another slot. Alternatively, insert the SIM card into a different smartphone and see if you can receive the authentication code.

Additionally, contact your mobile carrier to confirm that your plan has not been suspended, put on hold, or blocked for any reason. These issues can prevent new SMS messages from being received.
