When would you use this SMS gateway versus something like Twilio, Plivo, or Bandwidth.com terminating a DID for SMS service?

Lots of businesses really, really want a mobile number from me for some reason, don’t accept VoIP numbers, and I don’t want to give them my real mobile number. 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 have a recommendation for gsm usb sticks? Where do you get them?

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?

Do you have dozens of phone bills to pay every month?

In the UK you can get a SIM for free from most networks as pay-as-you-go (i.e. you add credit to it instead of getting a monthly bill). With most of those you can happily receive messages on it without ever spending a penny.

If you can't purchase the GNSS HAT, use an old Android phone and install Termux on it. Then run some bash scripts on the phone that will do the job. The phone will communicate with your network over wifi, and replaces both the Raspberry PI and the HAT.

For solving a problem always there are millions of ways..

I use gammu-smsd and forward it to iOS using Pushover.

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.

When you want to have telemetry from somewhere without access to a wifi network. The last I looked, SMS was also cheaper and lower power than mobile data.

The problem is that fixed part of most plans’ pricing make the cost prohibitive, not the pay-as-you-go component (eg the cost of a sim and phone number). 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.

I hardly use more than a couple hundred from my 5 000 monthly budget to external networks, on the same network they are free.

Does anyone know if you could you this combo to creat some kind of VoIP gateway that could forward calls to an app on an iPhone over the Internet?

You could probably develop one if you want. This is exactly what ride-hailing app Grab did in their app to make a call without exposing their phone numbers by forwarding calls to their server instead.

I'm pretty certain they wouldn't have used a raspberry pi for that

Can someone please explain to me the appeal of telegram (as opposed to signal)? Maybe I don’t understand something or am too old but how is it a safe haven compared to WhatsApp in the wake of the WhatsApp debecle. I just fail to understand.

It feels to me that Telegram is the closest thing to old school IRC that we "have"* right now. You can have public/private channels, you don't see other peoples phone numbers for no reason (you see their chosen nicks), you have bots, broadcasts and more.

* That has any reach beyond the people who would scoff at this sentence.

Telegram is not at all secure compared to Signal (in theory). However it has an awesome UI and lots of nice features (most of which are lost using secret chats).

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.

It's likely that this one is cheaper and more accessible to many, many people, including those in developing countries, since it doesn't rely on sourcing quasi-obscure hardware like the HAT
