eSIM Activation Failed Fix: Why It Happens and How to Fix Each Cause By Chester Takau · July 2026 TL;DR Power off completely for 30 seconds (not a restart) — this alone clears roughly 40% of activation failures "Unable to Activate eSIM" almost always means the QR code was already scanned once — ask your provider to re-issue it, don't rescan Stuck on "Activating…" before you've landed abroad is often normal — travel eSIMs finish activating once you're in coverage If the QR won't scan at all, enter the SM-DP+ address and activation code manually instead Running a physical SIM plus an eSIM (or two eSIMs)?
