What if Huawei Glory 8 can't recognize the SIM card and can't surf the Internet?

Unable to identify the sim card, it may be a card problem or an operation setting reason, which can be checked in turn.

Problems with the card itself: Maybe the SIM card is not a standard card; Cutting the card and using the card sleeve may lead to not reading the card; It may also damage the cardholder, and you can replace the standard SIM card in the operator's business hall; If the SIM card format is inconsistent with the SIM card format supported by the mobile phone, it may not be recognized.

Operation or setup problem: the phone may be in flight mode, and the status bar will display the flight mode icon. Slide down from the top of the screen, open the switch panel and exit the flight mode.

Or if the mobile phone is not restarted after inserting the SIM card, it can be restarted to ensure that the system initializes the SIM card. If you still don't read the card after restarting, it is recommended to back up the data before inserting the card and restore the factory settings.

If all is invalid, it may be that the card holder is damaged or there are other problems. You can back up the data and take the purchase invoice and warranty card to the nearby Huawei customers for after-sales inspection.
