The operator can only be changed if the phone is jailbroken.

If the phone is jailbroken, you can install the two plug-ins zeppelin and FakeCarrier. to change carrier.

The method is:

Open cydia and add the software source: repo.hackyouriphone.org

Then search and install the two plug-ins zeppelin and FakeCarrier, and you can replace them .

zeppelin plug-in

This plug-in can change the operator icon.

Install the FakeCarrier plug-in

You can change the carrier to the desired text.

I hope you will adopt it.
