i have a problem with the duo sim. One is installed in the car and one in my iPhone 11 Pro Max.
Sińce the card is installed in the car and car is locked and not in use, when somebody call me, he gets connected ted to the voicemail directly.
I switched cards today, the one from car installed in the phone and the other in the car. Now people can reach me on the phone, but when I am driving car, I don't have internet in the car unless I switch off the 4G in my iPhone.
Does any one had similar problem ? Is there solution for this situation? I don't see any sense of having duo SIM card system if I have to always switch the 4G or keep switching simcards.
In the first setup when people could not reach me by phone the internet worked in both devices (phone and car).
is there a mother SIM card or I do something wrong?
Thank you in advance.
