#2It’s also possible to do this by sending AT commands via serial - I wrote some python scripts to do so on my Thinkpad: http://blog.mclemon.io/thinkpad-x250-sms-and-gps-via-python

#3Great read, this spiraled me down a rabbit hole of research, posting it here in case someone has the same questions:
How phone numbers / phones work: https://www.youtube.com/watch?v=FZsajM6M3UY
How to buy a block of phone numbers: https://www.siptrunk.com/2015/12/how-to-find-did-number-bloc...
I'm trying to do a thought exercise on how I might approach building a Twilio side project, but after I buy phone numbers from sipTrunk, I wouldn't know how to connect it to sim cards.

#4I've inherited (then reinstalled) a monitoring system using SMS Tools. The modem has a long USB cable, and an external antenna. I positioned the antenna on top of the rack.
It's in the middle of the ground/machine floor of a large building, so there's a lot of thick concrete walls around, but it gets a good signal and reliably sends SMS alerts to me.

I don't know either, but suspect that something like this is involved: https://www.alibaba.com/product-detail/128-Slots-SIMBANK-rem...

Depending on what you want your project to do, you don't need to connect a phone number to a SIM card. Twilio does that for you, letting you use their API to send and receive SMS (text) messages with other phone numbers. It's the recipient's phone number, not your Twilio one, that's connected to a SIM card.
What the linked post here talks about is using a device that's basically a mobile phone in a USB stick form factor to send and receive SMS like you'd do on a mobile phone. You buy a SIM, insert it into the device, and start texting. That's the other side of what your Twilio project would do.

Edit: and a repository of modems that can send SMS on Linux is here :P https://wammu.eu/phones/
Re: Sending and Receiving SMS on Linux (2015)
#10I've long suspected that the only way to make an actually private/secure cellular phone is by bypassing 3G all-together and making it optional -- forcing the SMS/SIP features of the phone were actually on separate hardware that had very limited integration with the phone itself (essentially as dangerous as any external USB device would be)?
Most smart phones are considered pwned-by-default due to the inclusion of the 3G/4G/whatever chip you have no control over.
Of course, there's the whole issue of distributed trust by way of pre-loaded X509 certs but there are some relatively secure ways around that (keybase, meeting in person and swapping PGP keys, etc) that would move the goalpost far enough to where it might not even matter any more.
Does anyone know anything that's close to this? basically a phone that only uses SDR for connectivity?
