Fix Network issue in Huawei Phones

If you are a Huawei smartphone user and facing SIM card cannot be recognized issue? You are not able to receive or make calls, or the 4G network cannot be found? If you are experiencing any of these network or signal issues, follow the troubleshooting steps below to fix them.

No SIM card found

The icon means that your phone’s card slot does not recognise the SIM card that you have inserted. If you see that icon, please try the following:

– Clear off the dirt on the surface of your SIM card and restart your phone.

– Please always use standard SIM cards and do not attempt to cut them out on your own, as this may cause poor connection due to nonstandard shapes.

– SIM cards can be damaged by frequently removing them or using them in humid or strong magnetic environments. Test your SIM Card on another device to see whether it is damaged. If it does not work on the other device either, please replace your SIM card at your carrier’s retail store.

If your SIM card can be recognised on another phone, the issue may be coming from your device. In this case, please back up your data and request the Postal Repair Service on the official HUAWEI Support website or the Support App for a repair.

*Reminder: SIM, UIM and USIM cards are all phone cards with different names. Herein SIM card is taken as an example.

Unstable signal

An unstable phone signal might be caused by metal or magnetic materials interruptions or enclosed environments. If you have an unstable signal, please try the following:

– Remove any magnetic holder, or magnetic or metal cases that you may be using for your phone.

– If you are inside a building with poor signal, please go outdoors or move until you find better signal.

No 4G signal

The 4G signal might be disabled or lost under certain circumstances. If you cannot find 4G signal, please try the following:

– Swipe down from the top of the screen to open the notification panel, press and hold the Mobile Data icon to enter the settings interface and turn 4G on.

*Reminder: If there is no relevant option, it means 4G is turned on by default.

– Restart your phone or switch on and off the Airplane mode and enable 4G again.

*Reminder: If other phones using the same carrier in the same area have similar issues, it probably means that the local 4G network signal is generally weak and unstable.

If the issue persists, please try the methods below:

– Check and reset the Check APN Settings

Open Settings and type APN in the search bar > tap Access Point Names (APNs) to enter the Mobile data interface > select Access Point Names (APNs) > touch on the upper right corner > Reset to default.

– Reset Network Settings

If the APN reset did not work, try resetting your network settings. To do this, open Settings > type Reset network settings in the search bar > tap RESET NETWORK SETTINGS.

*Reminder: Resetting network settings will delete WLAN and Bluetooth connection records, and requires the lock screen password for authentication.

– Get official support

Find the root cause of the problem with Support App’s Smart Diagnosis feature. To do this, open the Support App > Services tab > Troubleshooting > START.

Alternatively, get in touch with us through Live Chat on the Support App or the official HUAWEI Support website.

*Reminder: The instructions above are followed with EMUI 10.1 as an example and it may be slightly different in other versions.
