Apple 6 has a signal when charging, so it can send and receive text messages, but it just doesn't answer or call' someone else calls'.

Some users find that the signal is not very good when using iPhone6. Bian Xiao will bring you a solution to the poor signal of iPhone6, hoping to help you solve the problem.

1: Switch flight modes.

When we use the iPhone every day, we occasionally find that the cell phone signal is unstable, sometimes there is no signal, sometimes it is full, and sometimes it is only one grid. Some netizens personally test it and can adjust it through the "flight mode". Turn on the flight mode and wait for about five seconds, then turn off the flight mode, and you will find that the signal of iPhone has "flown" back!

2. Manually select the operator

Generally speaking, after the iPhone is inserted into the SIM card of the mobile phone, it will automatically match and access the corresponding carrier network. However, many netizens find that the mobile phone signal is not good or there is no service, so they can manually choose the carrier network. Enter operator options in the settings to turn off the "Auto" function. After a while, there will be a network operator option, and users only need to choose the corresponding operator according to their mobile phone cards.

3: Restore network settings

After trying the above two methods, the cell phone signal is still poor, and users can also try to reset the network settings. Specific operation method: Settings-General-Restore-Restore network settings.

4: Refresh the machine

If none of the above methods can solve this kind of signal problem, it can be improved by upgrading the system. Connect the iPhone to your computer and run iTunes. Hold down Shift, click "Update/Restore iPhone", select the downloaded firmware, and you can start to brush the machine.

If all else fails, I suggest you take the iPhone to Apple for after-sales inspection!
