How to Set Up Your JustData eSIM (Complete Guide)

Activating your JustData eSIM takes only a few minutes — no physical SIM, no stress. Follow this step-by-step guide to get online instantly while travelling abroad 🌍.

Before You Begin

Make sure your phone is unlocked. If your device is locked to a carrier, it won’t accept other providers’ eSIMs. Most carriers can unlock your phone within 24 hours of your request.
