Wechat customer service can't open the SMS page.

If your mobile phone can't access the Internet, it is recommended that you troubleshoot by the following methods:

1 Confirm whether there is a network. It is recommended that you use it where the signal is strong;

2. Check whether there is any phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used;

3. Confirm whether the parameters of the mobile phone have been set;

4 Check whether the USIM card is plugged in. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.

5. Check whether there is any problem with the mobile phone, and suggest that you change the machine for testing;

6 If the traffic is capped, it will also lead to the inability to access the Internet;

No.7 was not registered in real name, and the service was suspended if the real name registration was not completed within the time limit.

If this is not the case, I suggest you contact Unicom's manual customer service to help verify. The actual situation is subject to local policies.
