A:Answer Be advised that an unlocked phone does not get "Activated". If you already have an active Sim card from your carrier, all you should need to do is properly insert the Sim into the phone, power it on and wait for the phone to read the networks that's being transmitted. Of course, once you get the bars and LTE/4G symbols, make a voice call, send texts and try to web browse to make sure everything does run properly.
