I have an old IPhone 4s on a very attractive plan which ended a long time ago but continue to pay the originating price. My question is, since I have had microphone problems with the phone for a couple of years I would like to replace the unit with a similar unit rather than have it repaired as the cost of repair is more than I can get a replacement. If I use my existing SIM in a replacement unit, will the new phone activate without affecting my contract? What else should I do to replace, ie locked to MTS , unlocked, identical configuration (storage capacity, model, etc.)
