By following these steps, you can find the specific roaming prices for your mobile operator and destination

Check your operators website
Visit the official website of your mobile operator. Look for sections related to international roaming or travel plans. This is often found under the “support” “help” or “travel” sections.

SMS notifications
Your home operator is required to provide information about prices and usage limits, typically through a welcome SMS when you arrive a new destination.

Roaming packages
Check if your operator offers special roaming packages or plans that can reduce costs. These packages often offer a set amount of data, calls and text for a fixed price.
