Your mobile phone can't surf the Internet normally? Don't worry, we will help you solve it.

Restart the phone

Remember to restart the phone after upgrading to the 4G package, otherwise the Internet access function may be affected.

Confirmation signal

Make sure that the signal is strong where you are, so that the network can be unimpeded.

Check the phone bill

Shutdown restart

Try shutting it down for 3-5 minutes and then restarting it, which may help you.

Traffic upper limit

Will the network automatically disconnect when the traffic reaches the peak of the month? Pay attention to the SMS reminder of Unicom, or check the package description.
