Hello forum! I just called t mobile, they said I will receive email instructions how to unlock my phone and if any problems they will walk me through it so I don't permanently lock my bb. I am traveling to China, I want to us my bb and all it's apps. I have glanced at china mobile website...does anyone know of any prepaid sims for Guangzhou, China or Hong Kong, China that will allow me to make voice calls to the US and use Internet on my bb? And can I use bbm over there? Or should I just buy a prepaid phone there and does the prepaid phone come with data packages? Thanks in advance if you can help!
