I have an unlocked iPhone XR and had my Rogers sim moved to my e sim at Yorkdale Mall. I am now in Europe with a Three pay as you go SIM card in my physical sim bay. I have Three as my primary sim, and Rogers as secondary. It works well, however my Rogers calls were going straight to voice mail even though I was not on a voice call on the primary sim. (It is supposed to monitor both sims and ring if you get a call, unless you are on a voice call on one of the sims, in which case the other call will go directly to voice mail, and you will not get a notification).
Bottom line is my secondary line (Rogers) was going straight to voice mail even though I was not on a call, and I did show signal strength on both sims.
By chance while troubleshooting I decided to remove my wi fi calling feature I had selected on my Rogers line, and that resolved the issue. I now receive calls from both sims.
