WIFI / International / no 3G

I am curious about international roaming charges.

I have the Droid Incredible 2. I think I successfully turned off all data roaming and 3G.

However,

*If I have Airplane mode on (and just play some games or take some pictures), then I do not have to worry about any international roaming charges, correct?-i..e. it's safe to use the camera and play some games while on airplane mode and I won't be charged any roaming.

*I'm in a WIFI area...if I put on wifi, I can go ahead and use skype --but again, I won't be charged anything correct?

Could I use gmail if I have WIFI on?

Basically, I just want to be safe that no data roaming will be charged..obviously, I will not answer my phone either.

Thanks for your help!
