If you’ve ever been hit with a huge cell phone bill after traveling abroad, you’re not alone. Data roaming charges are notoriously expensive, and they can put a real damper on your post-trip high. But there are ways to avoid getting dinged by your carrier. With a little bit of planning and the right esim and mobile internet provider, you can save hundreds of dollars on data roaming charges. Here’s how:

1. Track your data usage: Most cell phone carriers offer some sort of data tracking service that lets you see how much data you’ve used in a given period of time. This is a great way to keep tabs on your usage while you’re traveling so that you don’t exceed your plan’s limits and get charged extra fees. MTX Connect app, for example, lets you see the amount of time or data you have at any moment.

2. Get an international data plan: If you’re going to be traveling abroad regularly, it might be worth it to sign up for an international data plan with your cell phone carrier. These plans typically include a set amount of data that you can use, and they can be significantly cheaper than pay-as-you-go rates.

3. Use Wi-Fi whenever possible: Take advantage of Wi-Fi hotspots whenever you can to avoid using up your data allowance. Many hotels, cafes, and public spaces offer free Wi-Fi, so take advantage of it when you can. Just be sure to connect to secure networks only so that you don’t put your personal information at risk.

4. Use data-saving apps: There are a number of apps that can help you save data when traveling. One popular option is Opera Max, which compresses data so that you use less of it when browsing the web or using apps. There are also many apps that let you download maps and other content offline so that you can access them without using data. Google Maps is one popular option, but there are others as well. Be sure to do some research and find an app that works well for you.

Data roaming charges can be a real pain, but there are ways to avoid them altogether. By tracking your usage, getting an international data plan, and using Wi-Fi whenever possible, you can save yourself hundreds of dollars on data roaming charges when you travel. So next time you’re headed overseas, be sure to keep these tips in mind!
