Q10 use in Greece

[ccoltesq]

I am on my second Q10.  It is absolutely horrible about maintaining its "synch" with gmail and verizon email. I have not had internet service 95% of the time.

I am currently in Greece, and the local network is Vodafone GR.  I am unable to connect to the internet unless a wireless "hot spot" is activated.  And, when I do this, I incur data roaming charges.  This phone is really the worst.  I have tried everything, and in three days have incurred $50 in data roaming charges.  A friend suggested purchasing a sim card here, and I did from Cosmote.  However, their sim card will not work with Blackberry so I cannot connect through any wireless location.  Any suggestions?  My case has been elevated within Blackberry, but they have not been helpful at all.
