Sending international text messages (SMS) while you are abroad can be very expensive. If you are not careful, it can lead to an astronomical increase in your bills. But rest assured, you can keep in touch with your family and friends in other countries without emptying your bank account.
Many international text messaging apps and websites are free, meaning you won’t have to use your roaming. Turn off your mobile provider data or put your phone on Airplane Mode when you leave your country. Use Wi-Fi instead, and download one or two apps that provide international texting services.
