2. Please observe whether the SIM appearance is good.

1. Observe whether the metal surface of the SIM card is dirty, clean the dirt on the surface of the SIM card, and avoid poor contact.

2. If you are cutting your own SIM card, it is likely that the shape of the SIM card is not standard, and it is easy to loosen when installed in the card tray, resulting in poor contact. It is recommended that you bring your ID card.

Go to the nearest operator's office to change the standard SIM card for use.

3. Please verify that your SIM card functions well.

If your SIM card cannot be recognized when installed on other normal mobile phones, or if other normal SIM cards installed on your mobile phone can be recognized normally, it is likely that your SIM card is faulty, and it is recommended that you bring your ID card to the nearest operator's business office to replace the standard SIM card.

If the problem persists after attempting the above methods, we recommend that you back up your data in advance (third-party messaging apps need to be backed up separately) and bring your purchase credentials to a nearby Huawei Customer Service Center for testing.
