We wanted a "hotspot" (that is what we are talking about, right?) The wife has straight talk phone, and so we just started looking at the straight talk hotspot, Lucky for us the walmart associate, steered us to the ATT hotspot. He says that the customer service and usage rate is better with the ATT than the straight talk and they hear lots of complaint about the straight talk hotspot. We have used the ATT hotspot just minimally, but have been happy with "usage" rate.
With the straight talk phone we have called their customer service, but hate the whole process.
We have been kind of happy with the online chat/ordering process.
