Recommendations for 3G PPP modem?


#1

Can anyone recommend a 3G PPP modem for use with Cobra? Also where are some options to buy online?

Are there any catches to look out for?

Thanks.
Ross

Telit modem in that project is a good option but it is not 3G.
Buy any modem shoucl work fine as lon as it uses serial port as an interface.

3G modems are pretty expensive. Why don’t just use a regular GPRS modem?

Good point Joe, GPRS will do the job well. Do you happen to know where a board like in the microprojects example can be bought from? I found the chip, but nothing assembled like that. Also couldn’t find anything in GHI / TinyClr site carts?

Thanks for your help.

has anyone ever attempted to use a 3g USB dongle as a modem with the micro framework?
