3G version of LoNet 808 - Mini GSM/GPRS + GPS Breakout, SKU: 113990107
Simcom based. SIM5320E or another 3G & GPS Simcom chip.
AT&T is turning off 2G service in the US. Anything marked "GSM/GPRS" will stop working by the end of 2016. We really need a 3G, ATT-compatible modem.
Instead of SIM5320E I prefer the SIM5320A since it operates 3G in the 850Mhz and 1900Mhz frequency ranges. I believe those are the freqs that AT&T uses on their 3G network.
