How to disable the second SIM card in your smartphone?

Open the settings of your smartphone and in the “Connections” section click on “SIM card manager”. Next, select the SIM card that you want to temporarily disconnect, and change the switch next to “Enabled”.

  • You need to insert the second SIM into the phone,
  • Then in Settings to open the Manager of SIM-cards ,
  • Tap on the name of the second SIM card ,
  • and then move the slider from the “Off” position to the “On” position

SIM card settings

There are different settings for each SIM in the manager: enabled/disabled, icon to identify (SMS, Internet, work, home, SIM 1, SIM 2), the name and the network mode. I do not recommend changing any settings if you are not familiar with them.

  • SIM card enabled. You can turn off the SIM (the first, second or both at once. it does not matter) to save battery power, not to receive calls and if you are flying in an airplane.
  • The icon for SIM 1 or SIM 2. Use only these icons so you don’t get confused later.
  • Name of SIM. write the name of the operator to avoid confusion.
  • LTE/3G/2G network mode (auto). In some smartphones the second SIM card can work only in 2G mode (calls and SMS. without internet). 3G. calls SMS internet. LTE (4G). high speed internet calls SMS.

Call settings

Above we have chosen the priority SIM for calls. In the “Call settings” menu we are asked if each time we want to make an outgoing call if we do not use the priority SIM? Useful for the forgetful, when you’re constantly confused with the SIM you’re calling from. Personally, I don’t use this feature and find it unnecessary.

If you enable active mode here (in the SIM manager settings) you can receive calls on both sims even during a call. The feature is useful and is enabled by default.
