The essentials to know before choosing a destination and data bundle.
See all frequently asked questionsAn eSIM for international travel is a digital SIM with a prepaid data bundle for your destination. You install the eSIM profile on a compatible, carrier-unlocked device and use it for mobile internet without replacing your physical SIM card.
A data-only HolySim eSIM provides mobile internet, but no new phone number or traditional call minutes. After purchase, you receive the installation details by email. Your regular SIM can stay active for calls and texts; use apps such as WhatsApp or FaceTime for calls over data.
Yes. WhatsApp stays linked to your existing phone number while the HolySim eSIM handles mobile data. Keep your regular SIM active to remain reachable on your own number and select the eSIM as your data line. Check your regular SIM's roaming settings to avoid unexpected charges.
Install the eSIM before departure using a stable Wi-Fi connection. Check when the validity period starts for your chosen bundle and enable the eSIM as your mobile data line at that time. Activation rules and validity periods can differ between bundles.
