Can't send pics from iPhone 5 over tmobile?

I have a 200 mb plan and unlimited texting… I recently unlocked my iPhone 5 for T-Mobile & it won't let me send pics there isn't even an option?

You probably didn't put in the MMS settings yet, assuming that is what you are trying to use to send. If that is the case as well, iPhones on T-Mobile can only use EDGE which is the 2nd slowest data service available. Eventually they would be able to use 3G/4G though.
