If you buy a prepaid phone such as the Nokia 521 which is tied to T-Mo is the phone locked to the carrier and also does it come with a sim which you then just need to activate or is the sim purchased seperately?
Yes the 521 is locked to T-Mobile, and yes it comes with a SIM card you can activate.
Thanks! Have you unlocked your lumia 521? If so best way?
Yes I unlocked it. I put in my T-Mobile SIM of the account I've had for about a year, and after 7 days in the 521 it was eligible to be unlocked. T-Mobile gave me the unlock code. If you activate the SIM that comes with the phone (new account) you will have to use it for 60 days before it's eligible to be unlocked.
