Can Qoolline eSIM work on a phone with a custom ROM or rooted firmware?
Custom ROMs and rooted devices may lack complete eSIM frameworks and carrier services, which can break activation or data.
1. Prefer official firmware for reliable LPA (Local Profile Assistant) support.
2. Avoid beta/dev builds that change telephony APIs.
3. If you proceed, test with Automatic network selection, then try Manual to attach to a partner.
4. If data fails, verify APN matches the plan, save, and reboot.

Because environments vary, support cannot guarantee stability on custom ROMs. Use stock firmware where possible.
