I am beginning a personal project to try and monitor some remote analog variables from my cell phone using a cellular shield. I found quite a bit of info on GSM shields, but understand that GSM is basically in sunset mode in the US.
I was hoping someone could provide some input on what the options are for 3G shields. Also, I am also looking for some advise on what US carriers are out there that would have 3G pay-as-you go service.
The only 3G shield I found was the "Cooking Hacks" website.
Any advise or additional information would be greatly appreciated. I am not very well versed in the world of cellular. I think what I am trying to attempt is very do-able, I just need a little advise on the shield and carrier to help get me started.
Thanks in advance.
