Is it possible to receive emails in Europe if phone roaming service is not enabled? Or anywhere else (except the US) where GPRS service is available?
I heard it is but worth asking.
Thanks.

yep, do it all the time. I blocked my phone service with TMO so i didn't receive wrong number calls coming in an incurring huge roaming charges.

That works -- you can block/cancel phone service and keep BlackBerry data, as a data-only service. You will lose phone capability including SMS texting capability, but you will have no problems with email assuming your plan is configured correctly.

I tried blocking incoming calls since I don't use my BlackBerry for phone, that blocking worked, but that also blocked incoming SMS text messages. So I moved the block, and took the risk of charges for people trying to ring my phone for long enough to get the clock running.
