SMS issues

[alaraajavamma]

my pinephone can not send sms messages through spacebar but can recieve them and phone calls,

Check are there some messages stuck in modem.
Write this to terminal and press enter:
mmcli -m any --messaging-list-sms

If there are messages you can read them like this:
mmcli -s X
Where X is the number of the sms (it will be seen in the previous command output)

If the message is outgoing you can send it like this:
sudo mmcli -s X --send
Where X is the number of the sms (it will be seen in the previous command output)

If the message is incoming you might want to delete it after reading and you can do it like this:
mmcli -m any --messaging-delete-sms=X
Where X is the number of the sms (it will be seen in the previous command output)


To make all phone functions more reliable I highly suggest to explore Biktorgjs firmware:

Please do your homework before messing with modem but IMO without Biktorgjs firmware PP/PPP is no where near reliable phone as a phone.
