Can you send somebody a text message using your email?

Yes. What carrier does she have?
T-Mobile: phonenumber@tmomail.net
Virgin Mobile: phonenumber@vmobl.com
AT&T: phonenumber@txt.att.net
Sprint: phonenumber@messaging.sprintpcs.com
Verizon: phonenumber@vtext.com
Nextel: phonenumber@messaging.nextel.com

where phonenumber = her 10 digit phone number

Well done, @papayalily! Very thorough! GA!

@wundayatta Sometimes, you’re just too lazy to go all the way into the other room to see if the voicemail your sister left you was for real, or buttdialed, and you just need to email her a text asking if you absolutely must get up. And this is how I know.

you should use yahoo mail. It has a main feature where you type in a phone number and you can text it for however long you want. the only setback is that you only get 149 characters per text. To use it go to the “new” tab and click mobile text or something along those lines.

I do it all the time. From my track phone, it cost about 15cts.to text…on my computer it cost nada.

gmail also has a great add-on “sms to phone” which is free but unfortunately does not work for phones outside the US.
