Vivo mobile phone does not open the network, can it be located without inserting sim card?

No, if the function of "searching by SMS" is turned on before the mobile phone is lost, when the mobile phone is not connected to the Internet, it will try to locate the mobile phone through the ability of the operator's base station, and the mobile phone can only be located if a valid SIM card is installed in the mobile phone. If the conditions are not met, positioning cannot be performed.

If you mean whether you can locate a mobile phone without a mobile phone card, you need to meet the following conditions before you can use it:

1. The "Find Mobile Phone/Find Device" function was turned on before you lost it;

2, in the boot state;

3. A SIM card that can be used normally is plugged into the mobile phone or connected to wifi；;

4. There is a network signal where the mobile phone is located;

5. There are scenes such as third-party channel brushing, after-sales brushing, and clearing all data in the mobile phone (the scene of abnormally exiting the vivo account). If the mobile phone turns on the function of finding the mobile phone again, you can use the original vivo account to locate the mobile phone and send instructions to lock the screen, sound an alarm, back up data and clear the mobile phone.

if you refer to other scenes, you can go to vivo official website APP- my-online customer service-manual customer service for detailed consultation.
