Do you mean someone who has access to your phone or a scammer?
Generally no. Scammers have two main approaches though:
1) They can port your mobile number to another provider and then use the number to make calls. Not much you can do to stop this but do use two factor authentication to a mobile app for your bank and email account if you can.
2) They can call your phone and hangup after one ring. It might show a local number but if you call back you are actually calling an expensive service from Peru that will charge you a lot. (Don't call back missed calls you don't recognise)
PS you can disable international calls in MY ACCOUNT under Manage My Services. While you are at it turn off Premium Calls as well.
