(To save a new thread, I'm hopping on here.)
I'm going to Toronto this weekend. In case I need to make a call, I add the Canadian Roaming option onto my service the day before and canceling it the day after my trip. Last year, with my Pre, I had a couple of weird instances where my phone suddenly showed as being on Sprint's network though they have no coverage there that I know of. I'd thought I'd turned off roaming, but when I got my bill there was about three dollars worth of data roaming charges though I thought I was offline other than hopping on open wifi hotspots. I got Sprint to take off the charges, but I'd like to prevent going thru the hassle this time.
What do I need to shut off to prevent a repeat with my EVO? I know that all the location-based goodies like Google Maps or Sprint Nav will go bye-bye (have a free-standing GPS for that), but I'd like to be able to ride open wifi points. I'm still puzzled over what happened last year with the sporadic Sprint network hits. I would know when I was on their networks because I'd suddenly get Gmail pushes. Very odd.
