Apologies if this question is addressed elsewhere. I searched but couldn't seem to find it.

I have the 650 with T-mobile, POP account for email. it works fine in the US,but whenver I travel overseas (and I do so often) it will work only very occasionally, giving either time out errors, vpn errors, server errors, etc. nothing consistent and very very frustrating.

I'd be grateful for any suggestions to help.
Thanks, Mary
