What Apple says data roaming does
Apple’s documented wording states: “When you’re in a region not covered by your carrier’s network, Data Roaming permits internet access over a cellular data network.” This means the setting allows your iPhone to connect to a foreign carrier’s network so you can use data while traveling abroad.
How to avoid roaming charges on iPhone
Apple documents that turning Data Roaming off is the way to avoid roaming charges. However, if you have an international data plan from your carrier, you may need to leave Data Roaming on for that plan to work. Before traveling, check your carrier’s roaming rates and consider purchasing an international data plan that includes international calling and plans (International Calling Plans and Roaming on Carriers). To minimize data use while roaming, connect to Wi-Fi networks whenever possible and monitor your usage in Settings > Cellular > Cellular Data Usage. Disable automatic app updates and background refresh to reduce data usage while roaming (Settings > General > Background App Refresh; Settings > iTunes & App Store > disable Automatic Downloads and Updates).

Will turning on roaming result in additional charges?
Yes, roaming typically incurs higher fees than standard usage. Check your carrier’s rates before enabling it to avoid unexpected bills.
Can I use data while roaming?
Yes, data works while roaming when Data Roaming is on, but it can be costly. Use Wi-Fi or an international data plan to control expenses.
What if I am unable to enable Data Roaming?
If unable to enable Data Roaming, first ensure iPhone is connected to a cellular network (Settings > Cellular, check Cellular Data toggle is on). If unable to enable Data Roaming, ensure iPhone software is up to date (Settings > General > Software Update).
What if I have no network coverage while roaming?

What if calls and messages are not working while roaming?
