Unable to set Pay-as-you-go T-mobile USA

[shawon]

Hi I'm having problem with my Pay-as-you-go T-mobile USA swirlymms2 setting. I called tmobile technichian, and he tried many different way but didn't work at all. He could not make that 'm' green at all. Finally his decision was contact SwirlyMMS2 since this is a third party application and we've tried our basic setting so, try to contact swirlymms. There is nothing tmobile can do at this point. If I can't make this work, this will be my $12 waste Please help
my current setting is -
