While connected to mobile data, press the update button.

You can also use smart switch on a pc

It is possible to update your phone using your mobile data connection, if your network provider allows this. Some providers have a restriction on downloading software updates over their network.

It's recommended to use Wf-Fi to install the Ui7 software update but you can still use data if not available it will take longer and may fail to update thou.
