Whether you have a phone equipped with Mobile Web Access or not, if you can send a short text (6 digits), you can update your status on Facebook. (You can also receive friends' Facebook updates, if you like.) Complete instructions are on Facebook's site.
You must sign in to your account first. Once you do, here's how to get started: After signing in, click on "Settings" on the blue bar on the top of the screen, just to the right of your name.
That will take you to this page, "My Account." Just click on the link (circled below) for "Mobile."
That will take you here. Click on "Register for Facebook Mobile Texts" (circled below).
You'll then see this (below).
You can choose any carrier. TracFone isn't listed, but it doesn't seem to matter. It's probably an internal Facebook thing and should not affect your ability to text.
We tried AT&T, Cellcom, Verizon, Boost and T-Mobile, and it had no effect on the outcome. But if you have any problems, please leave a comment and we'll check it out for you.
After you make a choice, you'll get this window:
Follow the instructions and send the text message. Then click "Next."
You'll see this (below).
Enter the code that's texted to your phone, then click "Confirm." You'll see this (below).
If you scroll down the page (below) you'll find boxes to check (or not) depending on your preferences. Make sure, though, that texts are turned on. The other choices are up to you!
