Beta support: MMS on chatty/mmsd on Modem Manager - help/testing wanted!

[kop316]

Hello,

I compiled chatty from branch wip/sadiq/mm-account and mmsd-tng.

After sending an mms using mmsd/test/send-message as documented there: https://source.puri.sm/Librem5/purple-mm...ote_132496

Chatty outputs the following, and crashes immediatly:

```
10:20:43.1745         chatty-mmsd[ 4968]: WARNING: Your SIM or Modem does not support modem manger's number! Please f
ile a bug report
10:20:47.7195         chatty-mmsd[ 4968]:  ERROR: Receieved Modem Number +33633153377 different than current modem n
umber
```

I managed to get it working with this patch:

```

```

I'm using a SIM card from SFR (France) in a Pinephone. If I can be of any help I'd be glad to.

(by the way, heads up on the typo "manger" -> "manager", and on the indentation in this function).

Thanks for your work on this :-)

Hmm that is odd, the way mmsd-tng and chatty get the modem number is the same way.

Is this consistent, anf if so, please join the matrix chat room so i can see what's going on.
