I am currently a cricket customer and I am using an android phone. My wife has just bought a new unlocked iphone for me. So, I am thinking to take the sim card out of my phone and put it in the iphone. Will this work?
Yes, as long as the SIM cards are the same size. Just switch them out and you should be good to go.
It will work but be advised, they will lock your new phone to Cricket even if you did not buy it from them. I just did the same thing and am having trouble getting them to unlock MY PHONE!
