A step-by-step walkthrough for iPhone and Android, plus tips to avoid common mistakes.

Before you start

Make sure your phone is eSIM-compatible and carrier-unlocked. Have a stable Wi-Fi connection ready, since you'll scan a QR code to install the plan.

Install the eSIM

After buying, you'll receive a QR code by email. On iPhone, go to Settings → Cellular → Add eSIM and scan it. On Android, go to Settings → Network & internet → SIMs → Add eSIM. Follow the prompts to finish.

Activate at your destination

Label the eSIM clearly, then choose it for data when you arrive. Turn off data roaming on your home SIM to avoid charges, and enable 'Data roaming' on the travel eSIM line (this just lets it use partner networks — you won't be charged roaming).
