Hi All, I'm wondering if others have this problem. We have 4 accounts with Public Mobile and very often when I call my daughter the call will not go through on the first try. Then I have to dial again and it goes through. Wondering what the issue might be.
Years ago I experienced this issue occasionally, and my theory at the time was due to the lack of VoLTE: Most of the time the phone would be registered to the LTE network for data, SMS, MMS, but to make or receive a call, the phone would have to quickly switch back to the 3G HSPA/WCDMA network for the duration of the call. I though it was possible that if that transition didn't complete quick enough, or there wasn't enough capacity or coverage available on the 3G network at that moment, the call would fail.
The workaround at the time was to force the phone to stay on the 3G network all the time, and disable the LTE network option. Even though Public Mobile introduced support for VoLTE in early 2023, there are still many models of phones that are not compatible with it and continue to switch to the 3G network for calls. Maybe your daughter has a phone where this happens, and if so you could see if the phone has an option to force 3G / disable LTE as a troubleshooting option.
