The phone will communicate with your network over wifi, and replaces both the Raspberry PI and the HAT.
Oh wow. Various types of monitoring use cellular, house alarms etc.
Are those things just using LTE now?
For outgoing SMS, have Tasker or Macrodroid watch an email inbox and send emails to that inbox with a format like email subject line = recipient phone number, email message body = SMS body. Then parse it through those automation apps and have it send the SMS for you.
I did something like this before and it worked decently well but I haven't had the best luck with getting Android apps to run stable for long periods of time without manual intervention. Not sure if it was battery optimization settings or what.
For the longest time these were exclusive features to telegram compared to Signal:
* Delete messages at other party ("undo"), critical for deleting accidentally sent nudes. * Username only communication * Stickers (silly, but well kinda fun) * Bots (very easy to make your computer talk to your phone or a group this way) * link preview * Self messages as easy link/file sharing between devices. Super useful.
Signal is slowly catching up, but it's so buggy at times, I am starting to really hate it/distrust it (I also dislike MM's personality/opinions). Matrix seems to move at a better pace, with more useful features already (e.g edit, markdown, some fun things). I am happy to get rid of telegram for Matrix. One feature better then the other already: resync of lost messages from the distributed network and no reliance on telephone numbers as UID.
Edit: and now with the New Groups you can send people a group link so that they can add themselves. Haven't tried that out yet but that seems pretty cool
Then you can use any SIP client on your iPhone to connect to that Asterisk and make/recieve calls.
Edit: I just noticed that Gammu is still a thing and even used in this article.
I haven't found something like that.
The hat itself is somewhat expensive (for only GSM), especially compares to LTE USB sticks which can do the same (and more). But of course not as compact and nice looking.
So instead I have a stack of SIM cards plugged into GSM USB sticks (like this mostly is) and get the inbound messages sent to me via Pushover notification.
Do you use just one SIM card at a time, or do you have a usb stick that can hold (and operate) multiple SIM cards simultaneously?
The last I looked, SMS was also cheaper and lower power than mobile data.
We were able to use a LoRa-like layer to forward to a base station that then uses a VoIP provider to do the brunt of the communication work.
For fun
For the serial AT modem I use random Huawei LTE USB stick that I bought for 15 EUR years ago.
It was so cheap because it was provider locked, but there are keygens floating around internet that allow unlocking it to work on any network.
* That has any reach beyond the people who would scoff at this sentence.
Or Slack?
Carriers may be keeping a small (relative) amount of capacity up and running, but in the meantime prevent new activations (ATT does this with there 3G network for example), so "coverage" is a bit misleading in many cases.
It's like seeing that M.2 is PCI-E, and wondering if they can plug a regular video card into it. :)
Although for this project, I can construct systems in my head where this would be useful, centered around non-US mobile plans which are "calling party pays", with free on-net SMS. The US is "bill and keep", which makes sending SMS off-net largely the same as on-net from the carrier's point of view.
In "calling party pays", having a device on the same network as the controlled device is about avoiding per-SMS charges.

I have a few USB sticks plugged into a powered USB hub and Gammu watches all of them for inbound messages.
(This is why I laugh and laugh at people who insist that VoIP numbers are more "fraudulent" because of whatever. Right now, breaking no rules whatsoever, I can get a hundred mobile numbers that any service will accept, and they'll go for a year without needing any more money. Stop using phone numbers as identity verifiers, people. All you're doing is making it harder for the people who aren't technically savvy and accomplishing nothing to prevent actual fraud.)
It seems like it would be easy enough to change your setup to hide your actual location by locating the gateway elsewhere and backhauling with its own IP connection.
BTW are there any standard interoperable formats for transmitting/presenting/archiving text messages, akin to Maildir for email or SIP for voice? If not, maybe Maildir is the right answer.
And everyone tells me that only accepting "real" mobile phone numbers means they're just piggybacking on the identity checks that mobile carriers do. Which, if true, I'd like to introduce you to Constable George Crabtree and his nineteen perfectly valid mobile numbers, all of them with his name in the CNAM field.
All this does is prevent someone who's not tech savvy and who might be trying to save a bit of cash by using a Republic Wireless or TextNow or some other "free calls and texts!" service from fully participating in this new app-based reality we've constructed. Someone who actually wants to commit fraud will step right over these dumb speed humps and do whatever they like.
I'm not saying don't do fraud detection, I'm saying don't do fraud detection that is so screamingly trivial to bypass.
That being said short code support is middling, not quite as good as VoIP numbers that use Bandwidth.com (Google Voice uses them) or Onvoy.
