Openline works on the Xiaomi 13T through the standard Android eSIM install flow.

Install steps

  1. Connect the Xiaomi 13T to Wi-Fi.
  2. Open Settings and find the eSIM section — the exact path varies by OEM. Common paths:
  • Samsung: Settings → Connections → SIM manager → Add eSIM
  • Google/OnePlus/Motorola: Settings → Network & internet → SIMs → Add eSIM
  • Xiaomi: Settings → SIM cards & mobile networks → Add eSIM
  1. Scan the QR code from your Openline email, or paste the manual activation code.
  2. Confirm and label the plan Openline.
  3. Enable Data roaming for the Openline line.
  4. Set Mobile data to Openline.

Notes for Xiaomi 13T

  • Restart the Xiaomi 13T once after install if the network doesn't register within 60 seconds.
  • APN is set automatically; if data doesn't come up, add an APN named openline manually.
  • Dual-eSIM is supported — you can keep your home eSIM installed alongside.

Reach Openline support 24/7 through any of these channels:

When you write in, include your purchase code (the OL-… code we emailed you) and, if the eSIM is already installed, its ICCID (Settings → Cellular → tap the Openline line). That's enough for us to find your plan and diagnose without back-and-forth.
