Upgraded SIM card - now I cannot access GPRS

[Guest MitzEclipse]

I upgraded my t-mo sim card from an old voicestream sim card. everything works except gprs. I did not change any settings on my phone, however, now when I try to access yahoo or google's wap site or any other wap site i get: "Your plan does not support this feature'

Can anyone help? I've been on hold w/ tmo for about 1 hr now trying to figure this out. this is frustrating.

Thanks

My guess is you need to get T-Mobile to enable GPRS on your SIM

T-mobile called me and said there was a switch that they needed to enable. I was on hold w/ them for about an hour yesterday telling them that I didn't change anything on my phone.

Anyway, problem is solved..thx
