To utilize a WestESIM, your mobile device must be 'carrier-unlocked'. This means it should not be tied exclusively to a single mobile provider. Phones purchased directly from a carrier (e.g., T-Mobile, Vodafone) often come with a lock. We strongly advise confirming your phone's unlocked status with your home provider before purchasing a WestESIM to ensure seamless activation and service in your destination.
