You may need to have the service ?provision? the phone. T-Mobile?s network for internet-enabled phones is called WorldClass, and you?ll need that for your internet service ? although it may be an additional monthly cost if you don?t have it already.
You may also need to enable the wireless internet function within the phone, because that is necessary for msn and yahoo messengers to work.
If that doesn?t work, I?d definitely have a service tech at T-Mobile take a look at it.
i need help regarding samsung black jack 2. i have tmobile service i got the phone unlocked. everything is working perfect but msn and yahoo messengers are not working what do i need to do
