Openline installs cleanly on iPhone SE (3rd gen). It supports eSIM, dual-line, and modern iOS features like Data Roaming per line.

Install steps

  1. On the iPhone SE (3rd gen), connect to Wi-Fi.
  2. Open the Openline confirmation email on a second screen (a laptop, tablet, or the iPhone SE (3rd gen) itself for one-tap install on iOS 17.4+).
  3. Tap the install link, or in Settings → Cellular → Add Cellular Plan → scan the QR from your email.
  4. Follow the iOS prompts; label the line Openline.
  5. Turn Data Roaming on for the Openline line and set it as Cellular Data.

Notes for iPhone SE (3rd gen)

  • Openline supports 5G on iPhone SE (3rd gen) where the partner network deploys it.
  • Dual-line is supported — your home eSIM (or physical SIM on older models) can stay installed alongside Openline.
  • Wi-Fi calling on the home line continues to work when Openline is active.

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.
