Google Voice Hot Tip:
EASILY SEND FREE SMS TEXT MESSAGES TO ANYONE WORLDWIDE — EVEN WHEN YOUR PHONE HAS NO SERVICE
In Google Voice, make sure you have "SMS notification via email" turned On.
Create a Gmail Filter to add a Label called "SMS" to every email with a subject containing: "SMS from".
On your (Droid, Android) smartphone Gmail app… Go to label "SMS" to find the person you want and to SMS him – even with NO SERVICE! …on a plane or subway or whatever. …..by simply Replying to that person's SMS thread in Gmail!
Your SMS will be sent the very next moment your phone gets a signal!
Pretty cool, eh!?!?
Of course, there's never a charge for SMS because it's email….. and, well, because it's a Droid.
