Impossible to change SMS center number

Using /e/OS Applications
,
1

Hi there,
Following my thread in French here Centre de SMS impossible à changer? I wanted to share the fact that I change mobile provider, received a new SIM card, put it in my phone with /e/ and everything works except that I can’t send SMS. There is no where in /e/OS settings I can manually check and change the SMS center number (call SMSC). I tried to dial ##4636## and set manually the SMSC but I always end up with “update error”. Any idea?
Thank you

We try a lot of things in the topic in french (see above). But no solution.

If anybody have a clue, it could be very usefull.

Old post, but I m having the same issue with my freshnew Murena2.
SMS/MMS never send…
Sending SMS/MMS works on another GSM (SamsungGS9 with /e/os) with the same SIM card. Settings are the same on both GSM and receiving SMS and calls work on both

Different carriers handle this differently but it is a known issue that /e/ uses a library of Carrier Access Point Names; these settings can sometimes vary slightly from the Carrier’s latest settings in use.

APN on you device are found in Settings > Network and internet > Mobile Network > Advanced > Access Point Names.

You can compare these settings with those published by your carrier.

Some Carrier issues are explored in [LIST] Carriers that work or do not work with /e/OS country-wise.

It is probably worth scanning the whole thread to see if your Carrier is mentioned.

Also try search though threads with the tag apn ← is a link to see if this is the approach you might use.

  • (SMS and MMS use different technologies, it is expected SMS will work correctly, some Carriers may have dropped MMS from their published offering.)

Disabling 4G Calling was the solution, it now works

So, what does it mean in reality? If 4G Calling is disabled - can we expect voice calls cease to operate properly in the very near future? Meaning: when 4G calling is off does the phone use 3G standard for voice calls?
