It took me a month to get the mobile hot spot connected with AT&T and even now it does not pick up any hot spots because it is constantly down than on for hot spot coverage.

I rely too much on this hot spot to not have the confidence it will work as a new one should over time.

AT&T MiFi Liberate 4G Mobile Hotspot (AT&T) was returned due to lack of ATT support to put it on vacation until needed.
