If data roaming is turned off on your phone, you will not be charged for any cellular data usage while you are outside your home network coverage area. This means that you won’t incur any additional charges for using data services on other networks.
When you turn off data roaming, your phone will not connect to cellular networks for data purposes. Instead, it will rely on Wi-Fi networks for internet access. This means that you can still make and receive calls and texts, as well as use data services like browsing the web, using apps, and sending/receiving emails, as long as you are connected to a Wi-Fi network.
By turning off data roaming, you are essentially preventing your phone from connecting to and using data services on other networks, especially when you are traveling abroad. This can help you avoid unexpected charges and save money on your phone bill.
It’s important to note that even with data roaming turned off, you should still be cautious when using data services abroad. Some apps or services may still try to use data in the background, even if you are connected to Wi-Fi. To ensure that no unexpected data usage occurs, you can also consider disabling cellular data altogether or disabling specific apps from using data when you are abroad.
In my personal experience, I have found that turning off data roaming has been quite beneficial in avoiding excessive charges while traveling internationally. By relying on Wi-Fi networks for data access, I have been able to stay connected without incurring any additional costs. However, it’s always a good idea to check with your mobile service provider to understand their specific policies and charges related to data roaming.
