Thank you for posting a question on our forums. The Palm Pre does require a data plan to run on our network. This is due to the device constantly uses the internet to check for Email, software updates,and application updates. Please click here to see our great competitive data plans. One more great link that I have is a data calculator this will help you determine what data plan is right for you.
YOU SHOULDN'T NEED A DATA PLAN ON A SMARTPHONE! JUST BECAUSE THEY USE INTERNET DOESN'T MEAN THAT YOU CAN'T USE WIFI ONLY. VERIZON IS JUST TRYING TO STICK IT TO THE LITTLE GUY AND MAKE THEIR BILLIONS. THERE SHOULD BE NO DATA REQUIREMENT. YOU CAN TURN ON AND OFF THE 3G ON THE PALM PRE PLUS, HOWEVER VERIZON DOESN'T CARE! THEY JUST WANT TO MAKE $30 OFF OF EVERY TOM, DICK, AND HARRY, WHO IS STUPID ENOUGH TO GET A DATA PACKAGE.
