unable to activate after restore

I recently stumbled upon my old 5s and i decided to fiddle wwith it seeing i had given up on it years ago. Surprisingly the phone was recognized by itunes and it downloaded whatever files were needed but im stuck on the activation screen. I have tried to put on a sim but it just says no service and then it goes back to "searching". The two screenshots are from the attempts I made to activate the phone. One from itunes and the other pops up on the phone itself. Any suggestions would be welcomed. I've also tried m3u but the phone is not recognized there the connection just times out.
