So if on 2 calls at the same time using dual eSIMs with the iphone 14, does one of those calls still rely on WiFi calling or can both operate using the cellular network?
From the article you provided...
"Wi-Fi calling must be enabled for at least one of the lines." -- Though this article was from May of this year, so I am not sure it applies to the iphone 14.
I do hope you're right though as this would mean that both lines could be used at the same time when away from WiFi. This would make a big difference and be like carrying 2 phones at the same time.
