I can't reset my go phone account password from overseas! URGENT

I am a GoPhone customer and I can't login to my account even though my password is correct. Since I am out of United States for 3 months, I can not reset my password as I can't receive American text messages. I don't want my phone number to go into recycling and in order for that to happen, I need to have access to my account asap. I would appreciate any help regarding this.
