Honor eSIM guide
Does Honor 90 support eSIM?
Honor 90 appears in the co:sim compatible device list. Your exact market, carrier, and hardware variant still matter.
01
The short answer
Yes — Honor 90 supports eSIM in eligible cellular variants. Before purchasing, confirm that Add eSIM appears in Settings or its companion app and that the device is carrier-unlocked.
Check your exact Honor 90
A model name can cover different regional hardware and connectivity variants. This two-minute check confirms your exact device.
- 1
Open Settings on the device or its companion app.
- 2
Open the cellular, mobile network, connections, or SIM menu.
- 3
Look for Add eSIM, Add cellular plan, or a similar option.
- 4
Open About or device status and look for an EID. If the device supports dialling, *#06# may also show it.
What confirms compatibility
If Add eSIM is visible and an EID is present, the device has an eSIM module. You should still confirm that it accepts plans from other carriers.
Carrier unlock is a separate check
An eSIM-capable device can still be locked to the carrier that sold it. Ask that carrier to confirm the device is unlocked before installing a travel eSIM.
Regional and carrier exceptions
Overseas, Hong Kong, Macao, and Taiwan variants that expose standards-based GSMA eSIM can use co:sim. A mainland China variant with eSIM must be outside mainland China to install a non-Chinese carrier eSIM. Confirm Add eSIM and an EID on the exact device.

Honor 90 appears in the co:sim compatible device list, but availability can vary by country, carrier, and hardware variant. Confirm an Add eSIM option is visible before purchasing.
How do I check eSIM support on Honor 90?
Open Settings or the companion app and find the cellular, mobile network, connections, or SIM menu. If Add eSIM or Add cellular plan is available, the device supports eSIM. Check About or device status for an EID.
Does Honor 90 need to be carrier-unlocked?
Yes. eSIM hardware support and carrier lock status are separate. A carrier-locked device may reject a travel eSIM even when Add eSIM is visible.

It depends on the hardware. Many phones and tablets support dual-SIM use, while watches and some computers use eSIM as their only cellular profile. Active-line limits depend on the model and carrier.
