I have a remote site that needs internet access. I'm thinking of using a hotspot or usb modem (I don't need phone functions). My unlocked AT&T S5 works great with Ting (better than AT&T!!!), but only in 4G. There's no 3G signal at all out there whatsoever.
I've tried an Sierra Overdrive Pro (purchased from Ting some time back) that claims 4G support, but the devices page in Ting shows only CDMA (3G) support.
I've also tried a Sierra Wireless Aircard 250U bought on ebay, and it has the same problem (CDMA only support from Ting).
Does anyone have any ideas?
I'm tempted to purchase Ting's cheapest smart phone that supports 4G/GSM and hopefully it has a hotspot function. Is that an option?
