Yes I have data plan....I run mobitv, xm radio, a slingbox, internet, weather checker, emoze (some at the same time).. so a data plan is needed, plus it has a GPS .. unfortunately the battery only lasts about 8-12 hours under use... but I have enough chargers handy to keep it going...there is an extended battery you can get thru e-bay, but then it won't fit in the pouch I carry it in...HOPE THIS HELPS. |
