Why does my mobile phone show ee in the UK?

Ee is a network operator in the UK. If you take a mobile phone card from another country, it may be that the operator of the mobile phone card and ee in the UK are partners, so ee is displayed in the UK. The operation method is as follows:

1. First find Cydia on the mobile phone desktop, as shown in the figure below.

2. Enter the software source code-Edit-Add, enter the newly added source code, and install Zeppelin, as shown in the figure below.

3. After the installation is completed, go back to the mobile phone desktop to enter the settings, then go down and find the newly installed Zeppelin, and click it in, as shown in the figure below.

4. Finally, click on the carrier text in the upper right corner, enter your favorite text, click Save, and the operator will be set.
