What should I do if the network becomes abnormal after the program SIM unlocks my phone?

The network sometimes becomes abnormal after the SIM unlock because the APN is refreshed during the process for some phone models. To fix the issue, please follow the four steps below to make the network act normal:



1. Click "Settings", enter "More NetWorks".
2. Select "Mobile networks".
3. Select "Access Point Names".
4. Select the operator that you want to access.
