Nextel phones can send SMS to any country, and from any country that NEXTEL provides
iDEN service to (these settings need to be changed when you leave & enter the U.S. through your preferences settings). The Two-Way Messaging feature allows you to enter in full e-mail addresses as well as phone numbers. If entering the phone number by itself does not work for you, try sending to the phone using the e-mail address provided to the phone by the carrier. For example, if your NEXTEL phone number is (954) 555-1212, your e-mail address would be
9545551212@messaging.nextel.com This information is provided by almost every wireless carrier on their website. Check your friend's carrier's website in the Phillipines to examine. I use this method to vote for American Idol. (Yes, I am ashamed... but Cingular users can't have all the fun)
