What if the mobile phone card can't use data traffic and can't accept short messages?

If your mobile phone can't surf the Internet normally, please check the following:

1. If you don't restart your phone after upgrading to the 4G package, you can't use the Internet function normally;

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

3. 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;

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

5. Check whether the USIM card is inserted. 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.

6. Check whether there is anything wrong with the mobile phone. It is suggested that you can change your mobile phone for testing.

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. If you still can't get it after deleting it, you can change the machine or card to see if 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.
