Question about 8T (8GB) - 343418
is wifi-calling supported with sunrise? can be tested with the app https://play.google.com/store/apps/details?id=ch.sunrise.cfa&hl=de unfortunately, I don't have a device to test it myself.
Yes it will and without problems, my mother has Sunrise and an 8T in use. She uses this function every day at home.
