What if I travel abroad and put in a local SIM card? Do I have to change the international and area codes, too?
Yes, you have to change the country code. I've never tried the area code internationally, but I think it's better to put full phone numbers in and not use the area code.
If you travel a lot, you should put your numbers in the form of +1 (XXX) XXX-XXXX with the +1 in front and the area code. Well you don't need to change all your numbers, but the ones you are going to sms or call. That way you can just change the country code and the number will work fine from either place.
