im still here. ill be back to you when i finish talking to sprint person who handled it differently. . . . he exchanged the ipad for a new one and connected sprint service. im trying to find out whappened to old one.
YOur info has been very valuable. I'm a little confused about one thing --- in early part of answer you said the billing would stop if SIM card was taken out above it seems as if you are saying it will somehow stop automatically " as song as SIM card is not taken out."
Anyway, I will of course give you excellent feedback and a tip but if you can answer that one point about the SIM card I'd appreciate it.
In the end, the Sprint people told me the ONLY way I could get billing stopped was to call ATT, they gave me the number of the iPad (I didn't know iPads had tel numbers) and I called. So problem is solved but I believe the Sprint employee who took in the old iPad didn't know procedures or at least couldn't explain to me.
