Unlocked Samsung impression A877, but need MMS settings for T-Mobile

I have a Samsung Impression A877 (issued by ATT) that I've unlocked to T-mobile, I can make calls and receive them, but can not get on the web or send MMS/txt messages. How can I change these settings? Thank you.

(I've been searching btw.. I can't find anything that helps)

I can now gets txts to go through, but still no data like web browsing or sending pics... So i need the WAP settings

Ok Guys, Here's what I have. I can now access the web, I can send NORMAL Txts, and I can receive Normal txts and txts with pictures. I However can Not send pics in txts yet though...

I used these settings.

Going through the impressions menu as follows:

From main menu:

Settings,
Applications Settings,
Messaging,
Multimedia Message,
MMS Profiles

At bottom of screen - I hit Create
Set name -T-Mobile MMS
Access name - wap.voicestream.com
Auth Type - Normal
User ID - leave blank
Password - leave blank
Protocol - HTTP
Home URL - http://216.155.174.84/servlets/mms
Proxy address - 216.155.165.050:8080

Then I tapped Save.


Ok, for WAP (Web browser) Settings I've entered this:

1. Setting > Connectivity > Network Profiles > Create
2. Set Name > T-Mobile
3. Access Name > epc.T-Mobile.com
4. Auth Type > None
5. Home URL. >Mobile Phones, Internet, Email and Mobile Broadband - T-Mobile
6. Linger Time 300
7. Advanced Setttings > All boxes must be unchecked.
8. Save Changes


Still can not send a pic OUT Though.....

Thanks for the update - hopefully someone will respond that knows what the other settings need to be.

I've tried to edit one detail above, but it wouldn't stick. Where it says "3. Access Name > epc.T-Mobile.com" for the WAP info, there should be no "-" between the T&M in Tmobile. It should appear as "epc.TMobile.com"

Edit: Why does the "-" keep coming back into the posts? I know that I deleted it and typed the verse WITHOUT IT. Does the website automatically add it in?
