I have purchased my resale cell phone but I want to unlock it, so I want to know if there is a possibility of unlocking it from the provider
How can I request assistance from the company to unlock my cell phone?
You need to be a customer of Tmobile USA and meet the requirements in the link below. If you were never a customer of Tmobile USA they can't help you.
