Connect SIM module to a Gumstix?

Question

Is there a way to connect a SIM module to a Gumstix? I've tried to find commercial solutions (add-on modules) that will do this but have not found any. Surely an addon providing mobile connectivity must exist?

Just the sim card? Or do you want something that lets you communicate over GSM? Those are two very different requirements. — Nick Johnson, Jul 15 '11 at 05:36

Depending on the gumstix module that you have, if you are using embedded linux with a board that has USB host, then you may be able to use a USB GSM modem - you stick the SIM card into it and then the module into a USB slot on a gumstix board. You would have to find drivers or write your own. A quick search finds that some people have had success using a particular model due to driver compatibility.

There are also a number of GSM modules that you can interface with using a UART channel. They are typically spoken to using an AT command set over a serial port. If you're willing to explore not having a perfectly clean modular connection (like with the gumstix expansion boards) then there are a lot of options for you.

If you mean a GSM module and SIM card, it would be easy to interface them via a serial port. This unit has everything you need on one board. I once designed my own PCB interfacing a Siemens GSM module and SIM card to a PIC controller, it was quite easy.

Thanks for the link, however, I'm looking for something that interfaces directly with a Gumstix providing GSM modem capability and keeping the small form factor to boot. – kwo Jun 14 '11 at 19:20

I don't think that there is such a thing. I might design one, there is probably a market for it. – Leon Heller Jun 14 '11 at 19:26
Yes, I can imagine that quite a few people would be interested in something like this. – kwo Jun 15 '11 at 08:17

That is an independent wireless gateway product using 3G, but OP, imho is looking for a way to connect his gumstix to the net. For generic internet access he could use a regular PC as well. – bdutta74 Jan 25 '12 at 12:59
