HTC One Remix - Manual (Page 241)

Turning data roaming on or off
Connect to Verizon Wireless partner networks and access data services
when you’re out of Verizon Wireless coverage area.
Using data services while roaming is not part of your subscribed
monthly data access allowance. Check with Verizon Wireless for
data roaming rates before you enable data roaming.
1. Go to Settings.
2. Tap Mobile data > Data roaming, and then select a data roaming
option.
Select the Data roaming sound option if you’d like HTC One remix to play a
sound so you’ll know when it’s connecting to a roaming network.
Managing your data usage
If you're on a limited data allowance, it's important to keep track of the
activities and apps that usually send and receive data, such as browsing
the web, syncing online accounts, and sending email or sharing status
updates.
Here are some other examples:
§ Streaming web videos and music
§ Playing online games
§ Downloading apps, maps, and files
§ Refreshing apps to update info and feeds
