Cannot send SMS

Apps & Core Settings
1

Hello,
I’ve recently realized that I cannot send any SMS anymore.
Receiving is instead working just fine.

Whenever I try, regardless the recipient I use, I got an Error Code 104 from the Fossify app.
I’m running the latest Iodé OS 6.8 on a Fairphone 5.

I’ve already tried, as suggested elsewhere, to check my SIM card in another phone and sending was fine there.

I also created a second profile but the issue is reproduced there also.

Could you please advise on what I can do to get the issue sorted out?

Regards,
James

Country / carrier? My guess is that it may be your carrier force migrating your SMS / MMS messages to RCS now, which is not supported by microG or other non-Google Play Services embedded devices.

If you have your SIM in device supporting RCS using Google Messages you can in there disable it for the SIM, but you should also be able to disable RCS messages for your phone number “without your old (Google RCS enabled) device” by visiting here:

This is just speculation, but as I understand you certainly do want to disable RCS for your phone number, as they aren’t supported by microG ROMs. But if your SIM was in a RCS enabled device, your carrier may basically register your number as “RCS capable” thus leading to some of this headache.

Hi,

I’m using an italian mvno as for my carrier (coop voce, which is basically vodafone).
I checked through google messages if the RCS could be the things but it is reporting that my device/sim are not RCS capable.

Any other rhing I can try?

Thanks,
James

To get a broader understanding, are there any issues with cellular data?

Do you have MMS service? (I know many in Europe do not and you are better off for not needing it if that is true, just checking)

How do you receive the 104 error code?

I missed that you indicated you can’t send SMS anymore. So did this work before an update, or what changed?

Hi,

My mobile data is working just fine, no issue with that.

As for the 104 erro, it is raised by the Fossify messages app when I press the send button: it basically prompts me that it cannot send the messages due to this error code.

I cannot tell exactly when it stopped working (I’m not sending sms frequently) but I can confirm that last time I tried (around 2 months ago) I had no issues.

MMS are offered by my operator but I never used them.

The only changes I applied to my phone settings since there (but I cannot say whether it is related or not) are:

  • Upgraded Iodé OS to version 6.8
  • Created an additional user profile to the mail one

Thanks for your support,
James

To isolate it if is an app issue or a network issue, can you install QUIK SMS from f-droid and test if it has the same issue (it will prompt you to become the default SMS app, accept that … we can uninstall it later if no change)?

Hey,
That is something I’ve already tried with no luck.
However, I have an update that I’ve just found:
If I force the connectivity on 3g, SMS are just fine (both sending and receiving) so everything seems to be related to some buggy 4g/5g stuff that was not there before (never set my phone to 3g before)…

This may be something you want to pass to your provider, maybe it will uncover something on their side?

Hi,
I’m skeptical about this being a carrier issue as the same works just fine on other phones regardless the network type (but usually 4g).
