iPhone 5s AT&T
Hello,
I Have an i Phone 5s AT&T. I emailed the carrier they got back to me OK-ing me to UNLOCK the phone to be used with a different company. (Red Pocket)
The question I have is, During the UNLOCK process do I want to keep the original SIM (AT&T) in? Or put in the SIM (Red Pocket) I plan on using?
Thanks in advance.
