Unlock AT&T Nokia Lumia 920 on T-Mobile Messaging Settings

[rush_ad]

I searched a lot and saw people having different opinions and settings. I am posting a thread to collect specific feedback on this topic.

What are the options available under:
"Settings --> Application --> Messaging"

I have these on firmware 1232.5962.1314.0001
1) Text message back up (On/Off)
2) Chat backup (On/Off)
3) Group text (On/Off)
4) SMS center number (Text field for a number)
5) Add mms apn

I've heard other people have sms and mms delivery confirmation settings available. Please post your information. Thanks.
