The cell phone signal is not good, so I can't receive the short message.

According to the information you provided, the mobile phone prompts "No service", which you can detect in the following ways:

[1] Please confirm whether your mobile phone is set to airplane mode;

[2] Please confirm whether your mobile phone is in arrears;

[3] You can go to a place with good signal and restart the machine;

[4] You can change your card and try it on your mobile phone. If it works normally, I suggest you go to the business hall to test it. If not, it may be caused by the mobile phone system. You can go to the mobile phone repair point to check your mobile phone.

The common reasons why mobile phones can't answer calls and their solutions are as follows:

[1] Check whether the mobile phone is in arrears, and suggest to pay for recharging;

[2] Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

[3] Check whether the function or signal of the mobile phone is normal, and suggest to change the mobile phone or try again;

[4] If roaming to other places can't be used, it is recommended to check whether the local network signal is normal and whether roaming permission is enabled for this number;

[5] Try to restart or change the phone to see if you can answer the phone;

[6] Take the mobile phone card to the local business hall for testing or replacement.

You can't receive SMS or verification code due to the following reasons:

[1] You can check whether the mailbox is full first. If it is full, please delete some information.

[2] cannot be received after deletion. You can change the machine or card to test whether it is a hardware factor;

[3] After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If the above problem does not exist, please contact the local manual customer service to handle this problem.
