I still have the Alltel plan I had 18 years ago with Verizon. My Alltel Razor v3 suddenly showed NO SERVICE 3 weeks ago and the store says they don't know why and Customer Service and Chat says they don't know why. Both tell me to call/go to the other. The phone is fine as new with good battery, contacts and everything in phone works fine. Anyone know why I have NO SERVICE? All Verizon wants to do is sell me a new plan. But what happened to the service. Many thanks.
