Roaming charges are legitimate fees that consumers are contractually obligated to pay. Roaming charges may apply when you travel and leave your 'home' network area and 'roam' onto the network or coverage area of another provider. If you are faced with unexpected charges, you should contact your service provider.

Do I want data roaming on or off?

Roaming charges can get expensive, so if you're traveling outside your cellular plan's coverage area (which generally means international travel), you might want to turn off data roaming on your Android device. Don't worry about being left without internet.

How much does it cost for roaming?

What you pay for roaming charges will depend on your carrier, but plan for roaming charges to breakdown somewhat like this: $0.25 per minute while talking on the phone. $0.10 cents per text message. $2-$5 per MB of data.
