Yes you can
1. Heres the easy way (that i havent tried) you use a service called Teleflip. All you do is you send an email to 12011234567@teleflip.com where 201124567 is the phone number
2. The method i tried and works perfectly: Use AIM.It requires the AIM client and is not really an email client.This requires an AOL or AIM screen name but if you do have an aim screen name, its quiet fast and reliable in message delivery and very easy to use.
3. The old school method: send emails to
T-Mobile: phonenumber@tmomail.net
Virgin Mobile: phonenumber@vmobl.com
Cingular: phonenumber@mobile.att.net.
Sprint: phonenumber@messaging.sprintpcs.com
Verizon: phonenumber@vtext.com
Nextel: phonenumber@messaging.nextel.com
where phonenumber = your 10 digit phone number ( i haven’t tried this in a while but it used to work a few years ago)
4. Use http://www.txt2day.com/ . Direct messages to the cell phone from their website .Does not require email but since its a third party app – theres always a chance of spamming the sender even though they promise against spamming
Remember: the people who receive the message might be charged for an incoming text. So try keeping the emails within 140 o 180 characters (someone correct me on the number of characters on a text msg)
