On top of all the other issues faced by this provider (I am still unable to receive texts from abroad, my iPad and Mac are often not longer holding my messages etc). Every time I have wifi calling turned on, if connected to any wifi network I can’t make phone calls (or receive them for that matter)…as it kills the signal (and obviously I cannot even use wifi calling to call).

I reinstalled the iOS (on both phone and iPad, macs), reset the network settings, toggled the wifi calling off and on and reset phone, iPad and the like. No difference. This network is really dreadful….
