Why doesn't everyone switch to metro pcs?

Iv been to every phone store and checked out the prices from tmobile to verizon and sprint and they are all rip offs! For two lines they charge more then a 100 dollars per month how is that not ridiculously over priced! I hate these rip off services! No matter what deal you get in metro they only charge 80 bucks for any kind of phone with unlimited everything! And they even text you great deals before you pay month after month sometime i only pay 60 bucks for 2 lines! I just don't understand why people don't switch! I mean they sell iphones and samsung and the service is actually really good

It, s just the freedom of choice! I have to add nowadays people care about every penny to buy and spend and people check other advantages too!
