Can you activate an iphone for t-mobile without a sim card port?

My friend wants to sell me an iphone thats "factory unlocked". He says it doesn't have a sim card port for my T-mobile sim. He says that I can just take it to some place and activate it there's that possible?

The iPhone models without a SIM port are CDMA models for Sprint or Verizon. They can't be activated on T-Mobile, who uses GSM and requires a SIM port. Your friend is either misinformed or trying to scam you, because that phone will never work on T-Mobile, it's physically impossible.

  • Why port forwarding on port 80? I have a foscam home security camera and it needs port forwarding on port 80 if I want to use my iphone to view it from outside. Surely enough, it works as soon as I open that port. But isn't port 80 open by default? Else how could I view http websites in the first place. I don't get it. It's already open so why open it again?
