Dr. Stjohn O'Connor:

I forgot to say something related to that, namely Wi-Fi calling. Two or the three operators are offering Wi-Fi calling on the networks.

Ironically, I was talking to my own mother about this yesterday. She has a different broadband provider from her mobile provider. Depending on the nature of a customer's phone and the package, phone calls could potentially be made over Wi-Fi, so that somewhat addresses the indoor coverage issue. If a customer has decent broadband, the phone provider will use that. That is interesting, because I understand two of the three, but all three of them may be offered at most.
