Yes, but you can also have a Motorola phone but yes in order to have sprint service you need a sprint phone
you call sprint and you make a contract with them
It was Sprint PCS. "Scooter my daisyheads, dimple monkey". They used to have the funniest commercials.
Usually, buying a phone outside of Sprint for Sprint is difficult since it doesn't use SIM cards. I don't recommend buying phones for Sprint rather buy the phone through Sprint.
I have a sprint phone and I would like to know can I get a prepaid simcard for it
How do you reset your voicemail passcode on Sprint phone
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.
For every phone there is a cellphone tower that is giving service for the cellphone provider that you payed for. If you bought your phone at Sprint then it is probably getting service from Sprint.
