My factory unlocked iphone 4s doesn't recognize my sim card?

I purchased a used 32GB factory unlocked iPhone 4S on ebay and it will not activate with my t-mobile sim card no matter what I try either on the phone or in itunes. I'm pretty sure the phone is unlocked because I looked up the IMEI number online and it said the phone was unlocked. I did trim the sim card myself so it could fit in the iphone but it still works in my old phone still so I know i didn't damage the sim card. Any help on how to resolve this would be appreciated!

Facebook iPhone Messanger app, what counts as activity? - 1

Sometimes when you click on old conversation with someone it will say something like "active 4 min.ago" or "active 2 hrs.ago". Do you know what counts as activity? I doubt it is actively chatting on facebook as the times would imply that most people are super active in chats, and I don't think that is the case especially with most of my friends on there, so I'm thinking it might be last time they were signed in or something but I don't know.
