Yes, you can, as long as your device supports dual SIMs! Your regular SIM card will stay active to handle your calls and texts using your original SIM card and phone number. Meanwhile, your new holiday.com eSIM will be used exclusively for data, saving you from expensive roaming fees.
Kindly note that your ability to make and receive calls and texts using your original number while abroad, as well as any applicable roaming charges, will depend on your home carrier, not your holiday.com eSIM. We recommend checking with your carrier beforehand to confirm whether roaming charges apply while you’re overseas.
