Question: volte iphone se not working
I have an iphone se with ios 11.1.1 running.
My carrier is sunrise in switzerland. I have activated volte as soon as it was available with my carrier, however, even though it is activated, my phone always switches from 4g to 3g as soon as i make or receive a call (even if i have a perfect 4g signal).
Does anyone face the same issue?
