My Sidekick phone died last night (long story) and now I need to use my unlocked 7290 blackberry that I usually only use for travel.
I have a T-Mobile SIM card and just got rid of my Sidekick services and added on Blackberry data service.
However, when I inserted in the SIM card, it says "data connection refused". Please help! I have no idea what to do! My 7290 is originally an ATT phone but it's unlocked...how can I make it work with T-Mobile data?
