Sprint and T-Mobile are different companies. You could port your number to T-Mobile, but if you are under contract with Sprint, you will be charged an early termination fee. So if you're asking if you can transfer a Sprint Contract into a T-Mobile Contract. The answer would be; no.
Sprint coupons can only be used on Sprint products. T-Mobile does not accept any type of Sprint coupons.
No. Because Sprint is CDMA and T-Mobile is GSM. Sprint = No SIM. T-Mobile = SIM.
What "are" sprint phones? Sprint is a phone company like T-Mobile or AT&T the phones that they use have the sprint logo on them.
No. Sprint phones cannot be used on T-Mobile, unless they have a SIM card port.
T-Mobile because their prices are cheaper!
Sprint and T-Mobile are under two different mobile networks. Sprint uses CDMA, T-Mobile uses GSM. So, to answer your question, unless the Galaxy S4 Mini has both mobile networks built onboard, it won't be possible to flash it.
Yes you can use the htc evo on the sprint for t-mobile network service.
No. The networks used by T-Mobile and Sprint are incompatible. You can, however, keep your same phone number in lots of cases.
IF you meant 'transfer money from t-mobile to t-mobile' - You can't. T-mobile will not allow you to transfer a pre-paid balance from one number to another.
Generally speaking, one cannot switch a T-Mobile phone to the Sprint network. This is because T-Mobile uses the GSM standard, while Sprint uses the CDMA standard, the two of which are not compatible.
I know for a fact AT&T and T-Mobile will support a droid phone. I'm not sure if Verizon or Sprint does. You will have to contact them directly to find out.
Sprint, because when you have sprint the connection is always higher no matter where you are, unlike T-Mobile. I made a mistake of taking a T-Mobile phone because my friend always has a high connection when she is right next to me while I had a lower connection. But of course it's your opinion though!!!
