Can one forward SMS messages?

hg84

Is there some way in which one can forward SMS messages and notification of missed calls?

Not sure if you want to forward them to another profile or phone number.

to another profile
Toggle on "Turn on phone calls & SMS" in the user profile in which you want to access messages/calls.

to another number
Calls can be forwarded in the standard phone app:
Phone App> 3 dots> settings> calling accounts> select your SIM> Call forwarding

I do not know whether SMS can be forwarded in the standard messaging app. Perhaps with an additional app?

Sorry for not being clearer.

I was searching for a possibility to forward them in e.g. an email or some other form of message that would not be dependent on the cell phone network

Ah OK, then I didn't understand correctly.

I'm sorry, I don't know of any way to solve this with GrapheneOS on-board tools.

hg84 Hi, you might try SMS Backup+ https://f-droid.org/fr/packages/com.zegoggles.smssync/

I use it myself to backup and forward my sms (you can choose to receive/backup sms 1 minute after having received it in your phone) to my e-mail adress, you have the option to choose the destination, it can be you own e-mail server (in my case) or Gmail.

hg84

Thanks, will try it.

But it's a bit worrying that it hasn't been updated in almost six years

This one might be exactly what you're looking for, in case you can authenticate by username/password only to your IMAP provider:

(available via f-droid too)

I'm using it on a secondary (stock Google Android) phone in the admin profile as default SMS app, while nothing else happens in the admin profile. All the apps in use are on a secondary profile, which wasn't granted phone/SMS access.
That way, any incoming SMS gets copied into the configured IMAP folder and never reaches whatever SMS app is running in the other profile(s).

Easy possibility to have SMS-TANs e.g. available at independent locations of your phone - you can access it in your IMAP (sub-)folder wherever you are, while your phone stays wherever you want it to be :-)

huberto It is interesting, thank you. Does it send/backup sms instantly, when they are just received in the sms app?

Yes, it copies incoming SMS to the IMAP folder at receive time (not via SMTP, it's IMAP directly).
It also provides a keepalive setting - in order to ensure storage will be available when needed; keeping WiFi and NAT sessions alive e.g.
I haven't done much reliability testings - no experience how it behaves on flaky lines/servers...
If I didn't receive a SMS it always turned the culprit was too weak cellular service (lost tower connectivity). But the app itself performs like a charm for me - only personal issue is that it's referencing SMS0 and SMS1 for the two SIMs and I never can remember which one is what number... pilot issue ;-)

huberto Thank you. I will try this app. I am currently using sms backup+ app, but sometimes I have to wait more than 5 minutes for the sms to be received to my Imap folder.
