eSIM Problems After iOS Update

Updated: April 9, 2026

Carrier bundles and eSIM profiles can glitch after major iOS jumps while Apple’s stack also updates.

Steps

• Settings → Cellular → tap your plan → update settings if shown.
• Toggle Airplane Mode; restart.
• Download your carrier’s app and run any “refresh network” tool.
• Compare with Apple’s eSIM transfer docs; see also eSIM transfer blog.

If the line never registers, the carrier may need to re-provision—have IMEI2 ready from device info.
