SIM not working.

[malik121]

Hi,

I have been using Public Mobile since 2019 and have never replaced my SIM or faced any issues. However, over the last couple of months, SIM incoming/outgoing stopped working. I managed calls with VOIP, but now my cell does not show any SIM, though I changed slots with the other SIM and tried all phone settings; nothing really worked. I guess there is an issue with the SIM, and I need to change it due to recent changes made by the service provider. 

Moreover, I need to know about e-sim and how it works. Please suggest! @members

Did you check with your IMEI to see if your phone is compatible with VoLTE on the bottom of the link?

It might not be the SIM but your phone. eSIM is basically an electronic SIM built into the phone but it is no as transferable as the SIM. You need to purchase another eSIM if you want to transfer eSIM between phones. But with a SIM, you just pop it out and put It into the new phone.

What phone do you have?

If your phone is not on PM's VoLTE whitelist ( https://www.publicmobile.ca/en/on/get-help/articles/volte ) , then it will be using 3G for voice and it might be affected by this:

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 sufficient, 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)

If this is really what affecting your voice calls, there is really nothing much you can do other than getting a phone that is on PM's own VoLTE whitelist.

Thank you so much. The issue is partially resolved; the SIM is recognized, I receive SMS, and 4G data works fine; however, I am unable to make or receive incoming/outgoing calls. Your quick help is highly appreciated.

Public Mobile has not made any changes that require anyone to change to a new SIM card.  While there have been changes to the network, this has to with less of the 3G network being available.  Do you know if your phone can do VoLTE?
