Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Appears with the No card icon when your Honor phone cannot identify an inserted SIM card or shows only one signal icon with two SIMs inserted. Restart the phone, clean the SIM metal contacts, and cross-test with another SIM.
Safety first
Stop and check this first
- Do not use a SIM card cut into a non-standard shape: it may not fit securely in the card slot, leading to poor contact and detection failure.
- Back up your data before restoring your phone to its factory settings or taking it to an HONOR Authorized Service Center, because restoring factory settings will clear all data.
Safe checks you can perform
- Restart your Honor phone and re-insert the SIM card or try the other SIM slot
- Clean dirt from the SIM metal surface and check whether the card was cut
- Perform cross-verification using another phone and another working SIM card

Restart your Honor phone and re-insert the SIM card or try the other SIM slot
- Who:
- you, when your Honor phone displays No SIM Card Detected or the No card icon.
- How:
- restart your phone to identify the SIM card again; if the issue persists, remove and re-insert the SIM card or place it in the other SIM card slot and try again.
- Result that matters:
- the phone re-detecting the SIM card and restoring the signal icon in the status bar.
- If the SIM card is identified after restarting or reseating:
- a temporary contact or display glitch caused the alert.
- If the SIM card is still not identified:
- inspect the SIM surface for dirt and check its shape.
- Evidence to keep:
- whether the issue happens in both SIM slots or only in one slot.

Clean dirt from the SIM metal surface and check whether the card was cut
- Who:
- you, with the SIM card removed from the phone tray.
- How:
- check the appearance of the SIM card for surface dirt on the metal contacts, clean the surface promptly to ensure good contact with the phone, and verify whether the SIM was cut into a non-standard shape.
- Result that matters:
- restoring clean electrical contact between the SIM metal pad and the phone slot.
- If cleaning the metal surface restores detection:
- continue using your SIM card normally.
- If the SIM card was cut into a non-standard shape or still fails after cleaning:
- run the cross-verification test next.
- Evidence to keep:
- the condition of the metal contacts and whether the SIM is a standard factory card or manually cut.

Perform cross-verification using another phone and another working SIM card
- Who:
- you, using a second phone and another known working SIM card.
- How:
- insert your SIM card into another phone to see if it is recognized, and test another working SIM card in your Honor phone to isolate whether the SIM card or the phone is at fault.
- Result that matters:
- determining whether your SIM card fails in another phone or whether your Honor phone fails to read working SIM cards.
- If your SIM card fails in another phone or another SIM works in your Honor phone:
- replace your SIM card at your carrier's store.
- If working SIM cards also fail in your Honor phone even after backing up data and restoring factory settings:
- bring your phone and proof of purchase to an HONOR Authorized Service Center.
- Evidence to keep:
- the outcome of testing your SIM in another phone and testing a working SIM in your Honor device.

What it means
The cellular baseband and SIM slot interface in MagicOS or Magic UI query the SIM chip whenever the phone boots or the tray is inserted. When identification fails, the screen displays 'No SIM Card Detected', shows the 'No card' icon in the status bar (or only 1 signal icon when 2 SIM cards are inserted), or indicates that only emergency calls can be made. This message alone never proves that the internal SIM reader hardware is broken, since surface dirt, a manually cut SIM card, or a faulty SIM chip frequently causes the exact same symptom.

Symptoms and causes
Probable causes · in order
- Surface dirt on the metal contacts of the SIM card or temporary read glitchCommon
Dust or grime on the metal surface of the SIM card causes poor electrical contact with the slot pins, resulting in a SIM detection failure.
Evidence: HONOR Support - How to Fix the No SIM Card Detected Issue
- SIM card cut into a non-standard shape or poorly seated in the slotPossible
If the SIM card has been cut into a non-standard shape, it cannot fit securely inside the card slot, leading to poor contact or slot misalignment.
Evidence: HONOR Support - How to Fix the No SIM Card Detected Issue · HONOR Support - My phone incorrectly indicates emergency calls only
- Faulty SIM card chip or improper signal bar status displayPossible
A defective SIM card that fails in other phones as well, or an improper status display on the phone, prevents normal recognition until the SIM is replaced or the device is reset.
