I'm in Denver and trying to use a prepaid sim card with a BLU Tank II T193 Unlocked phone.  The phone is not recognzing the SIM card - should I try another SIM card or is there a special sim card for older GSM quadband phones?

Hey, @magenta4690638​!

As Chris mentioned, we'd like to know if you're getting any sort of error when using a T-Mobile SIM in the device. You may also want to make sure you have your phone set-up properly by viewing the settings for unlocked devices here: Bring your own device setup guide​.
