Lost 4G

Hi. A week ago I lost my 4G signal on a Huawei P20 Pro and despite having travelled in different areas it is still missing. Occasionally, there is a very weak sign of 4G but nothing usable. Tried all the usual fixes (on/off, aeroplane mode on/off etc etc) but to no avail. Heading abroad on Sunday and need a signal before then. HELP please!

The P20 Pro are Dual Sim Phones, make sure the settings for Preferred Network (Something like 2G/3G/4G(LTE) is set to preferred for the correct Sim Slot.

Unfortunately, the preferred network mode cannot be changed from 4G/3G/2G/auto

Thanks anyway.

It will be under Network Settings, if Dual SIM under each SIM Settings, 2, 3G or 2,3,4G Auto, it's a Battery Saving feature.

On some older Huawei Dual Sims the 4G only worked on one of the SIM Slots, Default was SIM 1 unless changed.

Another thing to check is the APN is correct, again for each SIM.

Does it let you do *#*#4636#*#* to get to Phone info?

Just a single SIM and that combo of symbols yields no result

Thanks again

Hi @Abennett205

Can you make and receive calls?

Are you able to try the SIM card in another phone to see if you have 4G signal?

Yes I have and it works fine, so it has to be the phone. Have an appointment at EE shop this afternoon.

Thanks for your help.

I visited the EE store in Braehead and a very helpful young man thought it was a SIM card issue. The card was scratched, so he replaced it and 4G signal started to come back while I was away on holiday in Croatia. However, biggest improvement seemed to be when Huawei did a system update on my phone a few days ago. All good now, so either SIM or system update requirement was the issue.

Thanks everyone for suggestions
