Enable Android Mobile data?

I currently have my old, locked Huawei Y-300 0100 lying around and all I needed to unlock are mobile data. Unfortunately, I can't pull down the taskbar and activate it. Does anyone know another way?

What happened to your bar? Finally, you can enable mobile data through the settings.

Go to an inn and log in to a free Wi-Fi. Otherwise, I see no chance more than your cell phone back

The bar is not yet available in locked mode on this phone. I therefore have no settings available

For this I would have to unlock the phone first. I would need hotkeys to activate anything, I do not have normal settings

Ah understand. Have you ever enabled USB debugging? If not, I do not see a chance.

I thought I had activated it, had already tried something with it, but did not run. Do you still have a procedure with USB debugging?

Install ADB on the computer. If you are lucky, the smartphone will accept the connection (but usually only if you have previously connected to the same computer) without being unlocked. Mobile data should then be activated as follows:

adb shell svc data enable

At least that works for me. You can try it. Another possibility is unknown to me.

You may be able to remove the lock if a custom recovery such as TWRP is installed.
