Hello,
I am trying to build a very small device able to do tracking.
I thought of using a GSM module and a GPS module.
In order to reduce its size as much as possible I've come to the idea of trying to integrate the SIM in SDcard. Is it possible?
Practicly the SIM is also a memory so if I allocate a specific area within the SDcard for this purpose, theoreticaly I think it should work.
Alternatively I was thinking of using the smallest SIM manufactured. Can someone recomend me some providers?
Thanks!
