The FreeStyle Libre system has specific regulatory requirements that often vary by country.  Thus, FreeStyle Libre readers and Sensors purchased in one market may not be compatible with FreeStyle Libre readers and Sensors purchased in other markets. If you are travelling, it is advisable to ensure that you take enough Sensors with you to last the duration of your trip. For further information, please call 01-426-801 using a landline, and upon hearing "Please enter the number you are calling now", dial the number 855-583-3354 to speak to one of our Customer Care agents.
