SMS usually is the easiest one to get it working as it works on both 3G and 4G .

Have you try Reset Network Settings ?

[frank88]

yes, I have tested my sim card with another phone, the sim card works on another phone. later, I changed settings on my phone, the data works, SMS not

@frank88 

which city and province you are at?

First, Redme 8  is compatible with PM network on paper

While your phone is VoLTE capable, it is not on PM's VoLTE whitelist ( https://www.publicmobile.ca/en/on/get-help/articles/volte ) , hence it is using only 3G for voice

Telus is currently  refarming the 850MHz band 5 spectrum and hence you are left with 1900MHz for voice calls.

While one compatible band is still sufficent, reality is  1900 MHz could have less coverage, depending on your proximity to a tower and hence you are seeing a poor or no coverage with voice  (Data is not impacted as your phone has the compatible bands on 4G/5G)

There is really nothing much you can do other than getting a phone that is on PM's own VoLTE whitelist.

This could be due to the decommission of the 850MHz 3G frequency. Older phones that doesn’t have the VoLTE settings will have issues.

Here is more information and scroll to the bottom of the link and enter the phone IMEI to see if your phone is compatible.
