A missing Add eSIM button does not have one universal cause. The phone may lack eSIM hardware, use a regional variant without support, be carrier-restricted or place the option under a different menu name.
Software version and organisation-managed device policies can also hide or restrict SIM changes. Confirm the exact handset before buying a travel plan.
Do not install third-party applications that claim to add native eSIM hardware. A normal app cannot create a missing embedded SIM.
Quick answer: Check the exact model and region, search Settings for “eSIM†or “Add mobile planâ€, look for an EID using *#06#, update the operating system and confirm unlock or management restrictions. No EID and no supported menu usually indicate that the variant cannot use eSIM.
Confirm that the exact model supports eSIM
Open About phone and record the full model number, not only the product-family name. Compare it with the manufacturer’s regional specifications and the NoveSIM compatible-device guidance.
Support can differ between devices sold in different countries. Dual SIM, 5G or NFC does not prove eSIM capability.
Look for the EID
Dial *#06# or inspect the device information page. An EID is associated with embedded-SIM hardware; an IMEI alone is not proof.
If an EID appears but the menu is missing, software, carrier or management restrictions become more likely. Do not publish the EID or IMEI when asking for help.
Search the correct settings menu
- On iPhone, check Settings > Mobile Service or Cellular.
- On Samsung, check Connections > SIM manager.
- On Pixel, check Network and Internet > SIMs.
- Search Settings for “Add eSIMâ€, “Download SIM†or “Add mobile planâ€.
Menu labels vary by manufacturer and software version. Restart once after a supported operating-system update, then check again.
Check locks and device management
A carrier lock may prevent another provider’s line even when the button exists. Ask the original operator to confirm the unlock status.
Work and school devices may use management policies that block cellular-plan changes. Contact the administrator rather than removing the management profile yourself.
If the button remains unavailable
Ask the manufacturer or carrier about the exact model, region and software build. If native eSIM is unsupported, use a compatible physical SIM, hotspot or another phone.
If the option exists but installation fails, follow the activation troubleshooting guide or contact NoveSIM support. Keep any partially installed profile.

FAQ
Does every 5G phone support eSIM?
No. 5G and eSIM are separate capabilities, and support can differ by model and region.
Can a software update make the button appear?
It may expose supported functionality, but it cannot add missing eSIM hardware.
Does an IMEI confirm eSIM support?
No. Look specifically for an EID and manufacturer confirmation for the exact variant.
Can an app add eSIM support?
No ordinary app can create native embedded-SIM hardware on an unsupported phone.
Final Recommendation
Verify the exact model, regional specification and EID before assuming that the missing button is a temporary software problem.
If the device should support eSIM, check updates, carrier lock and management policies; otherwise choose a compatible alternative before purchasing a plan.
