Not if they don't want to. They could buy the company and then shut it down and cancel all users services if they wanted.
But they normally let existing customers keep going with the same plans and stop new people from signing up with those older plans.
Like when ATT bought Cingular, ATT made there own higher priced plans and allowed existing customers to keep there current Cingular plans.
Also for a while I remember having my VoiceStream phone plan for a long time after T-Mobile bought VoiceStream.
I remember many years ago (10-15?) when Aerial first came to this market (Tampa). I signed up for a $50 per month, traditional cell phone service plan (with credit check, etc.). That plan was for 1000 minutes/month, true per second billing, first incoming minute was free, and I forget what else now. Well, that was a
really, really good deal, especially way back then! Then they were bought out by PrimeCo, then somebody else, then T-Mobile, then I forget who... well I kept that same plan through all those different carriers, up until 4 or 5 years ago, when I finally switched to Metro (and all that time, a better deal never came along, until Metro)!
Back on topic, I also hope Metro never sells to Verizon, or anyone else for that matter. The big cell phone companies have been screwing us for years! I love Metro, and hope they always remain an independent company! I don't understand why they would sell out now, they are really picking up steam and I only see continued success with the 4G and the much better phones they are getting now. I have been a vocal proponent of Metro for a long time now, I have been telling anyone who will listen that they are going to change the cell phone industry, and bring down prices.
BTW, that's why I don't complain when Metro's network has the occasional hiccup... because I am not going to change carriers, no way! I am going to vote with my dollars, and stick with the company that is lowering prices for everyone! They will only continue to improve and expand their network the more resources they have at their disposal. So why would I take my money away from a company like that, and give it to another company that would charge me an arm and a leg at every opportunity!
I am also very interested to see what the elitists will have to say, now that we are one of the "big 4"...
