The right decision varies according to your travel itinerary and phone settings, budget, and the type of SIM or eSIM you have.
This straightforward guide goes through all the necessary details in simple and concise terms. Besides the definition of data roaming, you will also figure out when it is good to keep it on, when to turn it off, and what the tricks are to prevent incurring extra charges. Furthermore, the guide has provided easy-to-read charts for understanding options quickly and selecting the best option for your journey.
What Is Data Roaming?
Data roaming means your mobile phone uses a foreign mobile network when you travel outside your home country.
When you are home, your provider uses its own network.
When you travel, your home provider does not have coverage in another country.
So your phone connects to another network, and that network charges your provider. Your provider then charges you higher rates.
Common roaming activities include:
- Using Google Maps
- Browsing Instagram
- Sending or receiving WhatsApp messages
- Watching videos
- Cloud backups
- App updates

Does Data Roaming Use More Battery?
Using data roaming may drain your battery a bit more since your device makes an effort to get connected to the international networks, particularly in the case of poor signal reception. Despite that, the difference in battery draining is usually negligible and not noticeable for most tourists. In the case of the usage of a travel eSIM or strong network coverage, the additional battery drain is generally quite low and so will not impact your phone’s performance significantly.

FAQ’s
1. When traveling internationally, should data roaming be on or off?
The answer lies in your mobile plan. Activate roaming if you are using a travel eSIM or have a prepaid roaming package, as your costs are already included. Alternatively, if you want to completely avoid extra charges and plan to use only Wi-Fi throughout the trip, then turn roaming OFF.
2. If I keep data roaming ON, will there be any charges?
Indeed, you might be charged if data roaming is kept ON even with your home SIM and there is no roaming plan added. The charges can go up to an extremely high range. So, to be on the safe side, use a travel eSIM, get an international plan, or just switch roaming OFF before you travel.
3. If roaming is OFF, can I still use the phone like normal?
That is correct; however, only when you are connected to Wi-Fi will that be true. The use of WhatsApp for texting, sending emails, and browsing the web are all done via Wi-Fi connection. Conversely, live navigation, the use of Uber, making online payments, and getting updates from social media will not be possible without mobile data, so you will have some limitations when out of Wi-Fi coverage.
4. Is it necessary to turn roaming ON for an eSIM?
Yes, most travel eSIMs require roaming to be activated in order to connect to local partner networks at your destination. This type of roaming is safe, as it is prepaid with the eSIM, which means you will not receive any unpleasant billing surprises. If you do not have roaming ON, the eSIM may either not be activated or not allow for data usage abroad.
5. What is the most affordable option for mobile data usage in a foreign country?
Travel eSIM is usually the cheapest and most convenient way to go, as it provides prepaid data at local prices, with no nasty surprises on the bill. Other low-cost options are getting a local SIM card or gernerating Wi-Fi only. Stay away from your home SIM without a roaming plan to not run into high charges.
