Check your adapters. Most will switch, but some are 110 only.

There are never enough outlets in a hotel room. I carry a 3 prong type extension cord with 3 outlets. This, with one adapter, allows me to connect items.

You can get a super multi adpater that will connect you with every known system. I prefer to get the cheap single adapters, specifically for the country I'm heading to. Frys sells them for $2.99 each. I usually buy a bunch, since the people I travel with never have the adapters.

IF you do need a 110-220V adapter, do not buy the cheap crappy ones. They do not work. Radio shack sells a true transformer for about $35 that really works. I have one, but usually I don't carry it.

Cell phones: CDMA (Verizon) and PCS (Sprint) generally do not work overseas which are GSM based.

IF you have a Blackberry and it is with T-mobile, you can get the internation data service for $20 per month. If you have another phone which uses GPRS, you can use the Blackberry plan...Make sure you select the service on your phone as "T-Zones"...or you will get a big surprise at the end of the month.

Getting and using a local SIM card is cheap and easy. But, I prefer to have a cheap GSM phone for that and keep my regular phone operational.

If you know you are going to be overseas for quite a bit and you know you'll have Wifi access, get some sort of VOIP. T-mobile offers a blackberry phone with VOIP built in. When in a hotspot, it switches to VOIP mode. If you are overseas and using the VOIP, there is not international call charge. I setup 2 of our guys with these phones and they went from $3000/mth each to $700/mth phone bills, each.

Always have some local currency. Lots of places don't take credit cards.
