|When using a 2G/3G SIM card, the 4G icon appears intermittently and then my device disconnects from the mobile data network|
After a 2G/3G SIM card is installed on the phone, the 4G signal icon is displayed repeatedly and the phone disconnects from the 4G network.
If 4G network is available in your local area but 4G services are not enabled on your phone, the phone will attempt to register with the 4G network because it is given higher priority. When the network detects that your phone hasn't enabled 4G services, the network access is rejected, resulting in your phone repeatedly displaying the 4G signal icon and disconnecting from the network.
To solve this, swipe down from the status bar to open the notification panel and tap and hold the Mobile data icon to enter the settings screen. Turn off the Enable 4G switch or set the Preferred network mode to 4G/3G/2G auto.Also we recommend to use a SIM card that supports 4G services in order to enjoy faster Internet speed when using the mobile data.
If Network mode is not displayed, it indicates that 4G is enabled on your phone by default.or
