Yes - the technology will work, but you'll need to make sure you operator has your account setup for roaming (as well as data roaming) and make sure the networks you want to use are included in their coverage.

Also, be sure to double check their prices and ask whether they offer any kind of data package that could make your trip a little cheaper. Some operators charge as much as $20/MB (US) which means a single email with a PowerPoint could end up costing about $100.
