I have not found any topic on this forum about my issue so I’m posting it out there to see if someone can help me about this.
System : Original Fairphone OS
I use my FP4 with two SIM:
- eSIM is work
- Physical SIM is personnal
With this two SIM cards, I have the following preferences setup:
- Mobile data card : eSIM
- Calls : Ask everytime which SIM to use (to avoid calling with my personnal SIM when I have to call back customers)
- SMS : Physical SIM by default, if I need to send with eSIM, I switch from the app (Google Messages app) and select the one I want.
Mobile data are block on the physical SIM, I just use it for SMS/MMS and calls only, I use eSIM data or Wifi if I need an internet connection.
My issue is that when I receive a call regardless of the SIM card, after the call, I can send SMS, give call, all work for both SIM card when I’m doing an action but on my physical SIM, if I receive a call or an SMS (after the first call is ended) people calling me get straight to my voice messenger and I can’t receive any SMS either.
The workaround I found is to make a call with my physical SIM that is not able to receive anything anymore to receive all SMS that I missed at once. I do not have feedback from the calling app if someone try to call me without leaving a voice message while this issue occured (but that might be the default use case for everyone only for the notification).
Others workarounds that work but are pain to do after any call I receive: reboot the phone / change the option on physical SIM on 3G/4G/2G network to another and switch back (had to use 4G to receive MMS)
My issue is that I think that somehow, the standby mode is stuck on the physical SIM card until I actually “use it” manually by making a call (sending SMS do not make me receive the one waiting to be send to me on the carrier network), I don’t know what to do with this, the fact that the SIM card enter in standby mode is already something that I have to deal with.
I upgrade from dual SIM old Asus phone with Android 6 for a brand new FP4 using Android 12 to find out my old phone handle call redirect between SIM card that a brand new phone can’t is disapointed enought but this issue is a pain for everyday usages.
I have already spend money on a new physical SIM card thinking it could solve my issue but it doesn’t.
Is anyone also encounter this issue ? Am I unlucky and get a phone with issue since the beginning ? This issue is happening since I have set up everything on this phone and I have no other phone handling eSIM to wipe everything on my current FP4.
Thanks for the reading and any reply I can get from here!
