Jitterbug J is an old phone with obsolete technology. It works, unless you cancel and try to re-activate it again.
The reason why it cannot be activated is because it can no longer receive over the air update. Even if the phone is still active, some of the features will not work because it simply cannot accept any over the air updates anymore. I know because I have one. I cancelled my service and went back after 6 months to try Tracfone but I find Tracfone design to be too complicated for me.
I bought the new Flip and is happy as a clam. Yes, it took me a week to get it activated but the wait was worth it.
Product or Service Mentioned: Greatcall Cell Phone.
Reason of review: Bad quality.
