Roaming plans are special mobile phone services that allow you to use your phone while traveling outside your home country. When you activate a roaming plan, you can make calls, send texts, and use data just like you do at home, but usually at a higher cost. These plans help you stay connected without worrying about losing service or incurring huge fees. Many mobile carriers offer different types of roaming plans, so it's important to check with your provider before you travel. Some plans may include unlimited data or discounted rates in specific countries, while others might charge per use. Always read the details to find the best option for your trip!
