Does anyone know of a solution (commercial is better) that provides a
server with SIM cards and allow controlling (making voice calls, SMS,
Data sessions) through API or scripts ?

I am not sure if I understand what you are asking for, but it sounds
like you are looking for an asterisk server.
[https://www.asterisk.org/](https://www.asterisk.org/)

3cx is an alternative. [https://www.3cx.com/](https://www.3cx.com/)

Both are selfhosted and offered as a service.. but, perhaps you are
looking for something else entirely?

What I’m looking for is a hardware that takes SIM cards (like a SIM
box) with a system offering APIs or scripts that allow initiating
calls/data/SMS using those SIM cards. Not sure Asterisk and 3CX
supports that.

If you are looking to insert 1 sim card only, quick way is to buy a
4g/5g mini pci-e modem (huawei, quectel, etc) and an external
connector box over usb (https://www.amazon.com/EXVIST-Dongle-
EG25-G-M2M-optimized-Module/dp/B0B39NWFGV). If you want to work with a
bunch of sim cards, buy a commercial sim gateway as it'll be cheaper.
You can communicate with the sim card with AT commands over tty.

Aaah.. right, well.. I don't think we are too far off in the line of
thinking.

So.. we need a bit of hardware that accepts a sim card but also sets
up the GSM connection. Without that it would quite pointless.
We are looking for either a modem, and then you can use asterisk on a
server/vm of your choosing and let it operate the gsm modem as a
"regular" modem. Think of hardware like the #08155 - (WOI-R900L-GPS) -
[https://www.atel-
electronics.eu/produkt.php?hash=08155](https://www.atel-
electronics.eu/produkt.php?hash=08155)  .. my preferred outbound sms-
modem on monitoring servers.

3cx calls it FXS support of multiple options like; sip trunks, modems,
pots and the sorts. And iirc, appliance builders like beronet have a
router/sim-fallback/3xc PBX solution in one.. perhaps harder to sculpt
to your liking.

And any other brand is just as good/bad as what I suggested, it all
works in similar ways.

Are you trying to set up an advert robocaller? If so f*** you. If
there is a legit use for this, tell us.

Thanks for "fuck you"ing robocaller companies, they are a cancer.
There is a legit use case for Telco companies to test roaming calls,
detect SIM boxes …

Good luck!

And the more specific your question, the easier it is to answer.. so,
don't be shy with details if you got follow-ups :)
