Why can't the US version of Apple's mobile phone access the Internet?

If the mobile phone can't access the Internet, it is suggested that you can troubleshoot in the following ways:

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. The total traffic generated by surfing the Internet in the current month reaches the peak of the package traffic, and the system automatically turns off the Internet access function and automatically resumes opening the next month;

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 it still can't be used normally after self-service troubleshooting, it is recommended that you contact the local manual customer service for verification.
