Does anyone have an idea how to modify the apn settings on my iPhone 4S with a 3 sim card?
I used to have an apn settings option when I was with O2 on my Settings > General > Network tab but that option has disappeared.
I want to delete the configuration under mms and tethering so I don't accidentally enable it and get charged extra.
