I’ll check out the iPhone docs but I’ve done a lot of trouble shooting already.
I unregistered my phone from imessage, changed my device to SMS/MMS through my carrier and reset the APN..just a few of the many suggestions I followed. Group messages don’t work at all and the only thing I can think of, without having to ask every iPhone user to make sure they switch on the SMS fallback, is that I’m somehow connected through my icloud account? I’m running out of ideas..
I have a physical SIM from T-Mobile
With contacts I believe I tried to export them in that format but when I went to ‘export all’ from icloud or contacts it would only export one contact at a time..did you have a similar issue or work around?
The issue is receiving calls..I think you’re right about the display switch..it’s in the on position but not green and I am unable to turn it on or off.
Anyone know what the caution sign or half smiley in the upper bar means?
Contacts: haven’t done .vcf export from iCloud in a longer time, but when I did, select-all / bulk export was possible via a button. This guide has screenshots of that: [HOWTO] Import contacts from Apple to /e/ cloud - the official docs say you can do command-a / control-a to select-all, and then hit the export button, maybe that was it?
“anyone using nextcloud?” murena.io itself is a nextcloud instance and there are many who self-host. You can point a /e/OS phone at any nextcloud and things should work.
caution sign / half smiley: in doubt, show a screenshot
Calls notifications: do you mind screenshotting this too? the general option is “on and grey”, but the permission to display over other apps - what AnotherElk alludes to - is a few options down and should be green and switchable
Messages: can your carriers customer support disable RCS and iMessages for your number? how widespread are OTT messengers (Signal, Whatsapp, ..) in your social circle?
