Very quik answer from the MMS patch author.

The problem comes from ModemManager, it does not know my number like described in

https://matrix.org/_matrix/media/r0/download/matrix.org/yAMQRHQGKhLKmJtbdeqixTCc/message.txt

Do others #mobian on #pinephone users have that issue?

Do you have any result to the following command:

mmcli -m any | grep -i number

#mobian #pinephone #MMS #modemManager #chatty
