Unlock Tmobile iphone 5s for sprint?

I have a fully paid iphone 5s that i got from tmobile and i'm switching carrier. Now i'm planning to unlock my iphone 5s so that i can use it with sprint… Will it work or i should sell it and buy a new phone from sprint?

No, it will not work. You can only unlock a CDMA phone to a GSM phone but not the other way around.

Yep. All iPhones since 4s are dual band, so they have both antennas inside. Once unlocked from Tmobile, you just need a new Sprint plan and SIM and you should be set. Best luck.

IPhone 5S from T-Mobile is GSM only and Sprint is CDMA so it will not work on Sprint.

Unlocked phones do not work on Verizon or Sprint as those are CDMA networks.

You'll have to get a Sprint phone for use on Sprint
