Dave Winer posted to his blog about his upcoming travel–thanks for the invite to Europe, even though we’ve only met once at gnomedex. Some answers to your questions:
1. Will my Cingular Blackberry work in Denmark, Germany and Italy?
Yes! It will work in all countries but you’ll need to call Cingular to activate international roaming. You should also call Cingular and have them put you on the Word Traveler roaming package. Its under $6/month and greatly reduces your per minute roaming / long distance fees. There’s also a Blackberry international roaming package. Under $70/month and it will save you *a ton* in international data roaming charges.
2. Will my Sprint EVDO work in any of these places?
I’m afraid not. Europe is all GSM, for the most part. Your Cingular phone and data devices will work everywhere. Your Sprint gear won’t work at all. However, you can get a data cable for your Backberry and use it as a data card over the GSM networks.
3. Will there be Internet on the KLM flight from SFO to Amsterdam?
I don’t have the answer to this. But for your sake, I hope so. Mid-flight wifi is amazing. So is satellite TV in the seat.
4. Will there be power at the seat, and if so, will it require an adapter?
This depends on your aircraft. Your reservation should list the manufacturer and model. Take that information over to this site to find out.
5. Which power adapters do I need to bring?
See #4. A great reference site for aircraft configurations, where the power is and what adapter is required. I bought this kit about a year ago and it has worked for me all over.
