AT&T Mmode Button


Jun 26, 2004, 10:27 AM
Have had the T637 for over a week now -- best phone I've ever had. One problem -- AT&T (my service provider) has changed the right soft menu button on the phone to an 'Mmode' button. I believe the normal state of this button when a carrier isn't involved is 'More' -- so it yields other options.

I rarely use Mmode (slow as death), and want to get it off my main screen. Does anyone know how to change/hack the setting to get it back to its default state?

Hmmm...interesting. I don't know how to do that off the top of my head, but I will look into it for you.

I use mMode all the time, but no need for that button there with the 'Online' button right on the side of the phone.

Give me some time and I'll get you an answer.

Any update on this?

While I can't confirm this at all ... I think the answer to this question is that AT&T is a money grubbing corporation that modified the firmware of the phone to better assist their bottom line. There are 3 different ways to access Mmode on the AT&T T637. The soft menu button. A selection button inside the main menu. The dedicated 'online' push button on the side of the phone.

A couple comments on Mmode -- it's a service I never use. It's painfully slow. Content is minimal (maybe there is a lot on there, but at the speed it loads, I'd be 97 years old before I experienced all of it). I believe AT&T charges you for every time the Mmode browser fires up on the phone. Basically -- it's a trap. It's big 'ol AT&T trying to force their ...

I don't like this either. The MMode button is right where the EndCall / Menu Back button used to be on my old phones so I keep hitting it by accident. Even just hitting cancel I've accumulated data usage :-(

You can disable this by editing the WAP profile. Remove the IP address.

Yes, I've also had this problem. I called ATT Wireless and complained. They gave me th same answer: edit the WAP profile and set the IP address to

Haven't gotten the next bill yet, but hope it works! I would prefer it if they would just let me put something else in place of the mMode button -- I might WANT to browse someday! (But probably not.)

hey thanks, I doubt you guys will read this, but the IP set to 000 really helps.

Ideally I'd like to change those buttons so they could be used for something else, but atleast this will save me money.

you can remove that lame Mmode button by flashing the T637 with an Uncustomized GDFS file. You will have to use a Terminator dongle to do this, but the process is very easy and quick.

All the files and instructions can be found FOR FREE on this website www.terminatordongle.com
