Solution to the problem that mobile phones can't surf the Internet normally.

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

Restart the phone

If you don't restart your phone after upgrading to the 4G package, you won't be able to use the Internet function normally.

Confirmation network

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

Recharge telephone charges

Check whether there is a phone bill in the account. If the balance is insufficient, it needs to be recharged before use.

Restart the network

Turn off the phone for 3-5 minutes, then restart the phone and try again.

Check USIM card

Check whether the USIM card is inserted correctly. If it still cannot be used after being plugged in, it is recommended that you go to the business hall to check whether the USIM card is faulty or change the card for testing.

Pay attention to traffic usage.

If the traffic reaches the peak in that month, the network will automatically shut down. I suggest you pay attention to Unicom SMS reminder or inquire about the package product description.
