2nd hand iPhone not activated

My friend gave me his old iPhone 5 c and did a factory reset before he gave it to me. I tried to use my Wi - Fi network to activate it, however, it comes up with a message saying "your iPhone could not be activated because the activation server is temporarily unavailable. Try to connect your iPhone to iTunes to activate or try again in a few minutes. I tried this several times after you forget the network, but it does not always work. I tried to use iTunes to continue the process of implementation, however, I can't update the iOS to 9.3.2. Whenever I try, I get the message "iTunes could not back up iPhone because a session could not be started with the iPhone. Please disconnect and reconnect the iPhone and try again. "Please tell me what I can do to activate it.
