VoLTE doesnt count against your data plan, you dont even need a data plan to use VoLTE. In fact, most carriers require VoLTE these days so when you first insert the sim card, your carrier has sent a configuration profile instructing your phone to turn it on. You can turn the data to “off” but it still leave it on for VoLTE calls only.
I know the SIM gets some information when the phine is turned on. I have never had data service on phone before, and I gave up cell service entirely awhile ago, so I was wonding how the iPhone could stay connected for service that has never existed or been used on phone.
Does that also work for people who never had data service and is a wi-fi only phone for calling, no cell/mobile service?
