Can you unlock an iphone 5s from cricket to be with tmobile?

My dads friend gave him an iphone 5s for free since hes moving away and didn't understand how to use it so he gave it to me but its from cricket. My iphone 4s is unlocked and connected to t-mobile so i wanted to know if i can unlock that cricket iphone 5s and use it with tmobile and yes the iphone 5s has a sim card slot

You can try buying a thing call Rsim mini or pro. Just look it up online and you will find it and it will tell you which one to use and how to use it.

No you can't. Cricket iphones are locked for US use. Cricket is the only carrier you will be able to use it with. Cricket is a good company though. You might just think about switching

Cricket iphones can be unlocked, but you must have the phone active with cricket for at least 6 months with uniterrupted service and the phone can work with a different company, but unfortunately the phones can only be internationally unlocked meaning they can only be used outside the United States region. After the the 6 months you must call cricket to get the unlock escalation processed to your iPhone, it takes about 24 hours for the process to happen then your phone is unlocked. I work for cricket and i have been talking to several represensatives about this matter.
