Time period for changes to activate..

[robbyrob]

I was getting close to going over my
texts so I decided to just go unlimited.. When I change do the changes activate at the moment or doci have to wait for the next billing period?

Thanks...

usually the next billing period, but call up ATT and insist that you want them to apply right away. They prolly will do it.

yeah they will usually do it for you but you will receive some proration
