Is iPhone data roaming a bit of a mystery to you? We'll clear up all your questions! Get clarification on what cellular data roaming is and answer the question, should data roaming be on or off? Plus, I'll tell you some tips on how to cut down data roaming costs without turning it off completely.
Data roaming, also called international data roaming, lets you use the internet, send texts, and make/receive calls in locations where your primary network carrier doesn't offer coverage. If you live in the USA, for example, your phone will automatically connect to the carrier you have a contract with. It may even work for free in neighboring countries, such as Canada. However, if you travel outside of the coverage region, you will need to enable data roaming to access the internet and send messages or make calls.
Enabling data roaming on your iPhone will let your phone use foreign network carriers to connect to the internet. You will be charged based on data use since you do not have a contract with these foreign carriers. When you enter an area where international data roaming is available, you'll usually receive a text message explaining the cost of using data (per megabyte), making calls, and sending texts. Roaming charges do vary across the world!
