Can you use bbm with wi-fi? - Answers

ONLY if you have a Data Plan to setup access to the RIM servers which is provided by your local mobile company. You need this be setup, meaning the only way to use bbm on wifi is to have a dataplan active which grants you authorization to the RIM servers to retrieve your PIN ties to that phone. Kinda of sucks but that's life. For GSM devices the data plan ties RIM's servers with your device via the PIN and not so much the SIM. So you can still receive blackberry data services without the SIM as long as you have the data plan on your account. So in other words the data transmission is still possible because you have data on your account that allows it to go through RIM's servers even through WiFi. So IF YOU cancel your data service then it most likely won't work because you now don't have the data plan which gave your phone access to RIM's servers.
