@Nate. Actually, another method you can do instead of waiting for ALL your contacts to send at least a SMS to you is to go to their contact in your address book and on their number add the country code and etc. eg. number is.. 6665553521 and country code for ur country is +1. I assume right now the number saved is 6665553521. Just change it to +16665553521. Store all numbers in international format. It should work.
