I use Trillian for instant messaging.
I've had an ICQ account for many years,
along with a Yahoo account. Most recently, I've been using an AIM screen name with Trillian.
On this page, I just want to share some nifty things I've setup that allow me to do some text
messaging to my phone using Trillian and AIM.
If you don't have an AIM screen name, you can get one by visiting the AIM's web site and click on "Get a Screen Name". Just follow through the process, but once you get to the point where they want you to download their software, stop. You don't need to download their software. You can then get the free Trillian Basic and set it up to use your AIM account.
The rest of this information assumes you've got Trillian and AIM.
So, you have to enter a plus sign (+), then a '1' followed by the area code and phone number. Then treat it like any other contact. Rename it, put it in a group, send a message.
(You'll also see that they have additional features that allow you to get news alerts, sports scores, etc.)
