Another WiFi 3G question

[Kpdoughboy]

So I'm traveling next week to Mexico and don't want to get all the roaming charges so my question is does turning on WiFi mode turn off 3G and EDGE? Also, what does airplane mode exacly turn off? And is there anyway just to turn off the phone mode? My last Samsung phone was a smart phone and I had the option to just turn the phone off and not everything else.

Thanks,

If you turn wifi mode on, all it will do is notify you anywhere you get into a wifi network. It will not turn the 3g off, or edge. If you turn airplane mode on, you cannot receive any texts, phone calls, or get on data unless connected to wifi. Call t-mo and you should be able to take off roaming charges.
