On Huawei devices with eSIM support (P50 Pro global, Mate 40 Pro global, some regional variants):

  1. Settings → Mobile network → SIM management.
  2. Tap Add eSIM.
  3. Scan the QR from your Openline confirmation email, from My Codes in the Openline app, or from openline.com/start after pasting your purchase code. Or paste the activation code manually.
  4. Confirm and turn on Data roaming.
  5. Set the Openline plan as Default mobile data.

Note on China-market Huawei phones

Huawei phones sold in mainland China typically lack eSIM hardware. If your Huawei is a China-market unit, Openline can't be installed at all — the physical SIM slot is your only option, which Openline doesn't support.

Still stuck?

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.
