Huawei Glory always pops up the usim card application.

After opening, stop or forcibly stop. In Settings-Application Management -sim card application, it should be enough.

Usim (Universal Subscriber Identity Module) card is the third generation mobile phone card (Subscriber Global Identity Card). USIM (Universal Subscriber Identity Module), also known as upgraded SIM, is a component of UMTS 3G network. The USIM card can not only do simple authentication function, but it has been proved that it is gradually transitioning to the mobile commerce platform and even the final multi-application platform. It is no longer difficult to realize other applications such as electronic wallet, electronic credit card and electronic bill on mobile phone. In addition to supporting a variety of applications, the USIM card has also upgraded its algorithm in terms of security, adding the card's authentication function to the network.

Although Huawei mobile phones have usim applications, there are no such items after they are opened. Moreover, it can be disabled in the following ways: open the application management in the settings, view all STK or Usim card applications and click Disable, so he won't jump out again.

In the early days, STK was used to broadcast news such as weather forecast, and to check the phone book and short message storage on Sim card. However, after upgrading to Usim4G card, this application should no longer support those broadcasts.

Then there is the push service upstairs. If you don't need these, you can also open the above location, find the push service and close it.

1. Maybe your sim card is not plugged in properly. Turn it off, plug it in and turn it on. 2. In Settings-Application Management -sim card application, if you stop using it or force it after opening it, you should be fine. That's how I fixed it. I don't know if yours will do.
