Howdy.. I've been using my first 'smart phone' (Blackberry) for a few months, and will be taking it to Europe (GSM /freq capable). I've used my other cell in Europe before, but it wasn't a smartphone. So - - want to make sure I understand more about data usage when roaming, vs. wifi, etc.

I will call Sprint soon and discuss that I want to use the phone internationally. I believe I will go into 'Manage Connections' and select "Off" for both 'Data' and 'Roaming' the day we depart for Europe.

I want to be able to make/receive phone calls and send/receive text messages. My understanding is these services do not involve 'data' but will be priced at different scale outside of my US plan.

I want to be able to send/receive email and believe I must wait for wifi hotspot to do this to avoid 'data' usage. (I will need to go to my internet email site -not- the 'messages' area on my phone)

I want to be able to use the Internet and understand I must use wifi to avoid charges.

Lastly, to use any 'apps' stored on my phone
- - if they use GPS they won't work b/c I will have 'data' and 'roaming' turned off ?
(ex. any Maps utilities)
- - if they connect with Internet they won't work unless I'm logged into a wifi site b/c I will have 'data' and 'roaming' turned off?

Am I 'getting' it? Thanks!
