I don't know how to tell you exactly. However, according to my experience, when it turns to "edge", I'm not gonna be able to use anything with internet function. I'm not able to receive email, open webpage or chat. I still can get sms and phone call though.
i just looked up my account on rogers and it says that i am still on the $45 voice and data plan until the 5th of the month, but the 4MB of data is gone...
My phone still says "edge"
SO confused. But I have the $15 email plan starting up on the 6th.
IMHO, generic data plan is a normal data plan that doesn't have BIS (like what I currently am using). Once you activate BIS, the 'edge' should actually change to 'EDGE'.
