Why doesn't the flow card send text messages?

1. If the mobile phone can't access the Internet normally, troubleshooting can be carried out according to the following conditions:

In case 1, the contact between the SIM card and the metal contact of the mobile phone is insufficient, so an attempt is made to insert the SIM card again.

In the second case, if the SIM card is damaged or there is something wrong with the mobile phone, you can change the machine and test it to find out whether the SIM card or the mobile phone is faulty.

In case 3, the current position is a signal blind area or there is no signal suddenly. You can test it in another place and pay attention to whether the cell phone signals of other users around you are normal.

Situation 4: If the mobile phone card is in arrears, you can pay the arrears and start the mobile phone.

In case 5, the service was suspended because the number was used abnormally, for example, the number was used for illegal or illegal activities.

In the sixth case, roaming in Taiwan, Hong Kong and Macao and international roaming can only be used before roaming in Taiwan, Hong Kong and Macao or roaming abroad.

Situation 7: When the total traffic generated by surfing the Internet in the current month reaches the package traffic cap value, the system will automatically turn off the internet access function or speed-limiting network, and automatically resume opening next month according to the traffic cap rules of your package.

2. If you mean that the mobile phone can't send short messages, you can try to restart the mobile phone or replace it for testing, and check whether the following conditions exist:

(1) SMS center number is set incorrectly, please re-enter the correct SMS center number;

(2) No signal or insufficient battery power;

(3) The mobile phone shields the short message sending function;

(4) blacklisted by SMS;

(5) The quantity balance is insufficient.

3. If you still can't solve the problem after self-troubleshooting, it is recommended that you contact local manual customer service to assist in verification and handling.
