Data roaming is the use of cellular data services on a mobile device when you are outside the coverage area of your home network. This means your phone connects to a different, local network (often in another country or region) to access the internet, send texts, or make calls
. Mobile providers have agreements with other networks to allow this "roaming," so you can stay connected even when traveling. However, using data while roaming often incurs additional charges, which can be significantly higher than your usual rates, depending on your provider and location
. In summary, data roaming enables your phone to use mobile data on networks other than your own when you are outside your provider’s coverage area, allowing continuous connectivity but often at extra cost
