An eSIM (embedded SIM) is a digital version of the SIM card that’s already built into your phone. Instead of inserting a physical SIM, you activate it by scanning a QR code or tapping a link. Once installed, your phone connects directly to a local network in the country you’re visiting, so you can access mobile data instantly.

Here’s how it works step by step:

Purchase online – for example, through BitJoy’s app or website, you choose a data plan.
Receive activation details – you’ll get a QR code and/or direct install link by email.
Activate instantly – scan or tap, and within seconds your phone is ready to use. No shops, no plastic cards.

Why travelers use eSIMs:

Cheaper than roaming: Instead of paying your home carrier’s high roaming fees, you connect directly to local partner networks, getting local prices.
Instant global connectivity: BitJoy’s platform, for example, lets users activate mobile data in 190+ countries within seconds, avoiding the hassle of buying local SIMs.
Convenience: You can switch between multiple eSIMs if you’re traveling across countries without swapping physical cards.
Safe and private: eSIM technology is approved by Apple, Samsung, and Google. Installing it is as secure as downloading an app, and it doesn’t affect your personal number, calls, or messages.

👉 In short: An eSIM is a digital SIM built into your phone, activated by a QR code, giving you fast, flexible, and affordable mobile data wherever you travel.
