19．How to Manage Your Phone's Data Use

•If possible，wait until you can connect to free Wi-Fi before using your phone's data features．
•When you are on the road，use your car's GPS，not your phone，to find the way．（38）F But maps are preloaded in a GPS，making this free to use．
•（39）G Many of these are funded by ads that pop up on your screen．Every ad has to download through your network，using up your data allowance．
•If you regularly need to use a lot of data on your phone，consider a data-compressing（压缩） app，such as Onavo（www．onavo．com）．（40）D So you use less of your monthly allowance．You may have to subscribe to such compression services，so you'll need to weigh up whether it's worth the cost．

B．Remember to use free Wi-Fi anywhere you go．
C．Try these tips to better manage your data use．
D．It compresses data before it is fed to your phone．
