According to a survey conducted by comparison website finder.com.au, six percent or about one in 15 users stray over their phone's mobile plan's data limit. This is costing Australians $10 million every month.

Tech expert Angus Kidman says that the solution to the problem is by shopping around for a better plan.

Going over the data limit is most rampant when travelling. If going overseas, avoid paying the roaming charges by getting a local sim card or choose a better plan suited for overseas travel with your mobile network.

"Using mobile data or your phone overseas doesn't have to break the bank, but it's up to you to do your research before getting on that plane to avoid getting ripped off," Kidman says.

Here's how to cut back on your data usage:

- Facebook new feature that autoplays videos is eating up your data usage. Disable it and just watch the videos that you want to watch.

- For music lovers who are enjoying spotify, you can set it to download songs only when you're using WiFi or enjoy the offline playing option.

- If you're just playing games on your phone, put it in airplane mode as some games still use the internet even if it's not required for the game to function.

- Set the video and photo qualities to as low as you can to reduce not just the data use but it will reduce the buffering time too.

- Restrict apps from using cellular data. You can change options and allow some apps to only function when you're connected to a wifi hotspot.

- Disable Background App refresh. Not just it will eat up your battery life, it also uses up your date without you approving or even opening the app. It syncs your mail, calendar, and other apps which may seen small but will add up overtime.
