Text to Email and Back Again

How to spam your friends and coworkers with texts, from your email or from their service provider webpage. It’s FREE . . . on your end at least.
I have the instructions for Telus, Bell and Rogers email-to-text. If you know the drill for other providers, please comment below.

Telus:
You can send a message to any TELUS Mobility digital PCS or Mike phone or alphanumeric pager from your computer using e-mail. Just address the message to 10digitmobilenumber@msg.telus.com (e.g., 4031234567@msg.telus.com)

Bell:
Each Bell Mobility cell phone has a unique e-mail address: (10 digit cell phone number)@txt.bell.ca. For example, 4165555555@txt.bell.ca
Reply to the message as you would any other text message

Rogers:
1) Your phone's e-mail address is your10digitphonenumber@pcs.rogers.com2) You will receive a 'Message Alert' when an e-mail is sent to your phone.3) Simply reply to the Message alert* if you want to receive the message, or block the sender from sending you future messages.

Messaging from the service provider websites could be handy too, though with Rogers you must be a Rogers client, and sign up to receive a code on your cell/BB before you send your first message.
