I'm 'grandfathered' in on Verizon's old 'unlimited' data program so I'm trying to get the data limiter to be completely disabled (or removed if that's possible).
Going to system->data usage->and unticking 'set mobile data limit' works to disable the mobile limits for a few days but after a while it re-enables itself and I get the 'mobile data limit exceeded' notification. Setting the data limit to some ungodly amount (terabytes) doesn't seem to have any effect.
The phone is a Razr Maxx with stock ICS 4.0.4. Not rooted currently but if that would help in solving the issue I have no problem making it happen.
