I received the new Sierra Wireless Air Card this week. It is supposed to replace my existing old Rocket Stick using the same SIM Card. It worked when i first installed the SIM Card and charged the battery, but today it shows it connected on the air card, but no actual connection to Rogers exists, even though I have full bars - so I swapped back the SIM Card into my old Mobile Internet Rocket Stick and managed to get connected again. I am also using Vista Software and it has not been a problem.
I've sent off an email to Rogers Technical Support
