FYI,
I went to the ATT store. We received this message multiple times:
"Hmmm....something's not right. To sync this device, ask the person who manages your account to call us at 800.331.0500. (EDS4007)"
Finally, she got it to work and this was on the old grandfathered plan. I pay just $10 more a month too. That said, I will probably switch to the new Unlimited Plus plan since we have four lines total with the kids. They are on Cricket now but we will save if we move them to ATT.
I would say if it is just one person, the old grandfathered plan is still best. If two people, it is about the same price for old grandfathered or Unlimited Plus. If more than 3, the new Plus plan is better. We lose our 25% discount but new Plus plan is still cheaper.
I just hope there is not a catch...
How did you get past that sync error????
