Hello – I’ve never used a cellular module before like the Telit or the AVR-GSM. I am planning on getting one to add to a project. However, I have a couple of basic newbie questions regarding how these work before I buy one. I’ve never communicated via one of these before.
-
I see that they operate off of an activated SIM card. Can this simply be a SIM card activated with “voice” service or does the account need to have a “data” plan as well? I’m wondering if the communication these modules produce look like voice conversation to the service or do they look like data.
-
I’m trying to design the land-line side of my communications. What type of device do you call with these modules? Do I call a land-line with a modem attached (like an old-school 14.4Kbs modem) and talk that way or is it some other form?
I’m looking to be able to:
-
Call this module from a land-line and give commands.
-
SMS text this module from another cell phone and give commands.
-
Have this module send SMS texts to another cell phone with data.
-
Have this module send data to a local PM with a modem attached.
Can I do that with one of these?
Sorry for such basic questions!
Thanks…Rich
