Thread Details - HUAWEI Community. I have inserted 2 Sim cards in the Sim card slot on my P40 lite . However Sim 2 does not reflect and the device doesn't show Mobile Network > Sim Management Option.
Another solution to try is resetting the SIM card. Go to the device's settings and select "Mobile Networks." Then, select "Advanced" and "SIM Card." Finally, select "Reset SIM Card." This will reset the connection between your Huawei P10 and the SIM card. Check your Huawei P10 SIM Card Slot

Getting Started This feature is only available on dual SIM phones. Open Settings. Touch Dual SIM management. Touch Default calling SIM and select your desired SIM card. After you have selected the default SIM card, SIM 1 and SIM 2 will no longer be displayed on the dialer. Page 15: Transferring Data From Another Device

1、Take the SIM card out of the molile wifi. 2、Insert it into an available mobile phone, and make a call. 3、Remove the SIM card from the mobile phone insert the SIM card into the mobile wifi, and the SIM card is in the activated state. The mobile wifi does not prompt you to activate the SIM card.
