I have several projects that I would like to integrate with the GSM shield from SEEED studios, but had some general questions that I have not seen the answers to in docs or tutorials online so far:
- Any major difference between version 1 and version 2? I found version 1 in Radioshack for $25 but hesitated in case V2 is far superior.
- My more pressing question is the best approach to getting a SIM card. I've always been Verizon, so SIM cards are a bit alien to me. For North America, what type should I buy, what can I expect to pay, can I do this without buying an actual phone?
Thanks so much for any help!
