What is data roaming? Everything you need to know
Data Roaming: What is it? how does it work? when to activate it? These questions and everything you need to know about this service.
Data roaming almost looks like the perfect way to have mobile internet anywhere. It allows you to stay connected even when you leave your carrier’s network. This sure sounds convenient, but data roaming charges can quickly run up a hefty phone bill on your account.
Follow along to learn how data roaming works, roaming costs, how to turn roaming on and off, and some alternatives you might want to consider when traveling.

What is data roaming?
Data roaming is the use of mobile internet outside of the coverage area of your cell service provider. In simple terms, data roaming allows you to use internet on your mobile device when you’re abroad.
That said, the price for the data you use abroad isn’t usually included in your regular monthly plan. Depending on the country you’re visiting, data roaming fees can reach up to $5/MB or more, which can quickly run up an eye-watering bill. So, make sure you’ve got a contract that includes roaming or get a daily roaming plan before turning on your data roaming abroad.
How does data roaming work?
Data roaming is made possible by partnerships with other cell service providers from all around the world. Whenever you turn on data roaming abroad, you’re automatically connected to a local network that has agreed to partner with your regular service provider.
Once connected, you can use your mobile device to stay connected online, access your favorite apps, and make and receive calls and text messages through other cellular networks.
You should not be able to tell the difference in how your mobile device functions and you will most likely get all the mobile data you want. The main difference is in the expensive phone bill you’ll receive at the end of the month.

Pros and cons of data roaming
If roaming data is so expensive, why would you want to use it at all? Here are some pros and cons of using data roaming when traveling to help you decide whether or not it’s a good choice for you.

Data roaming sure is convenient, but it’s also often the most expensive way to get online, even if you get a roaming plan and avoid the outrageous pay-as-you-go fees. Let’s take a look at some of the best options available if you want to avoid data roaming charges.
How to avoid data roaming
There are essentially two things you can do to avoid paying for data roaming. You can either avoid using the internet altogether or find alternative mobile internet options.
Turn off mobile data
You can’t rack up a bill for data roaming if you’re not using mobile internet. It’s as simple as that. Turn off data roaming on your phone and you won’t be able to access mobile data services outside of your own network. You can also disable mobile data altogether just in case to ensure that you don’t use any data abroad.
Turn on airplane mode
Airplane mode disables all communication services on your mobile phone, including mobile data, calls, and messages. Enabling it ensures that you won’t use any data and won’t get charged for roaming. However, it also means that you won’t be able to make or receive calls and messages, which isn’t very convenient.
Use WiFi
Public WiFi hotspots give you internet access wherever they’re available. Nowadays, it’s common to find free WiFi in most restaurants, cafes, airports, hotels, and even shopping malls. You can connect to such networks to get online, but keep in mind that they’ll only work as long as you’re within reach of the network and will cut out as soon as you leave.
Get an eSIM
If you want to avoid roaming charges and stay connected wherever you go, an eSIM is easily the best option for you. You can buy and activate an eSIM online within minutes and enjoy non-stop coverage wherever you go. All you need is an eSIM-compatible device and internet access for the few minutes you’ll spend buying the eSIM.
Much like roaming, eSIMs connect you to local networks in the country you’re visiting. However, you pay the full price upfront, and there are no hidden fees to be afraid of. On top of that, eSIMs are usually cheaper than roaming plans, making it a more budget-friendly option.
With eSIMs, you can choose the provider yourself, and you’re not tied to your regular carrier. So, you can simply select the eSIM that suits you best in terms of pricing, coverage, and user experience.
