Some banking apps refuse to work over networks they consider "unusual" — including foreign carriers or perceived VPNs. The problem is on the bank's side, not Openline's.

Fixes to try

  • Open the bank's app on Wi-Fi first, complete any 2FA challenge, then switch back to Openline data.
  • Whitelist the app in any content-blocker or MDM profile you might have on the phone.
  • Contact the bank's support and mention you're travelling; some banks silently flag foreign SIMs and require a manual verification.

If a specific bank consistently blocks Openline, tell us. We track this and occasionally get IP ranges re-classified with the local partner network.

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.
