I've already hit over 1000 minutes on Wind. When I had Rogers set up with My5+Worldline, Unlimited Incoming, Unlimited Network Calling and 1000 evening & weekend minutes, I pulled 6000 minutes a couple months. Most of that was talking to my girlfriend. It's pretty easy to hit 4000 minutes if you've got a significant other to talk to. Right now I'm hitting only 1000 because I live with my girlfriend, but it'd be a hell of a lot higher otherwise.
Unlimited is really just the comfort of knowing you don't have to watch your usage, and that's worth a lot. I'd rather pay $35/month for unlimited on Wind, than $30 for 2000 minutes on some other carrier. $5 is worth peace of mind.
250 messages is also on the borderline category, it's a pretty solid number, but it's also not very hard to exceed. 2500 text messages is much more reasonable, and since it's essentially no cost to the carrier, having a cap just prevents excessive use of it. While plans like 2000 or 4000 minutes on CityFido are certainly resonable, as is the 6GB data plan, it's nice knowing that if you have to, you actually can go over.
If it's only unlimited EDGE/2G voice, they also won't be using much bandwidth, and it's easy enough for them to offer.
The word 'Pentaband' means '5 Bands', from the Greek word 'pente' meaning '5'. For a phone to be pentaband it has to support 5 bands. If the phone has AWS support, it doesn't automatically mean that it is pentaband.
Don't send me PMs for questions that can be asked publicly.
