No you can roam, just not on their system. If you have a tri mode phone go into network settings and change them to allow the phone to roam. I have done that and picked up a signal. A recording came on and said it was the cellular roaming network and you needed a credit card to raom. They said the cost was 2.99 per day. If this is true I am going to cancel my Verizon which I keep for when I travel. I was just wondering if anyone has tried this and had success with it.
I talked to a MetroPCS store manager a he said that yes, MetroPCS is working with a major carrier to cooperate in their nationwide roaming system that will only cost us a fraction of what it costs now! Stand by! Things will only get better!
