Yes you can.
You can use a Verizon phone for the nTelos Frawg program as long as it is not a smartphone.
You would not be able to use a T-Mobile phone through nTelos due to T-Mobile runs on a GSM based tower system and nTelos uses CDMA
Depending on the make and model of the Verizon phone you would be able to use it on nTelos services. The best bet would to be to find this information and then call nTelos Customer Care at 1-877-468-3567 to have them verify it is compatible.
There is a possibility that you would be able to use talk and text if you had the phone flashed to nTelos. Unfortunately, the data will not work.
Being that the Samsung Gravity T is a T-Mobile device you would not be able to use it on nTelos' service due to the phone is a GSM based device and nTelos uses CDMA towers.
Unfortunately, the Helio phone would not work on nTelos service.
Depending on the make and model of the phone you should be able to activate a US Cellular phone with nTelos. Please contact 1-877-468-3567 for nTelos Customer Service to have it verified before activation!
Unfortunately, nTelos is a East Coast based cell phone provider. There would not be a store in this location.
Unfortunately you would not be able to use an iPhone for nTelos. They do however carry a Samsung Showcase phone that looks and functions very similar to the iPhone.
No. You can buy an unlocked phone that is the same model and use it for another network but typically a Sprint phone will only work with Sprint and vise versa.
no
You cannot put an unlocked device on Sprint. You also cannot unlock a Sprint phone. I use the term "Sprint on Sprint only" meaning Sprint phones for sprint service, and no one else may use Sprint phones. **** Not true. You can unlock sprint phones and use them with other carriers.
