Also, not sure if you're billing has glitch they haven't caught it but the kickbacks on my account are only $8 per line because they take into account the hookup discount. I think this is the normal thing for everyone with kickback. I can't remember exactly how affects it but I remember I couldn't figure out why and then something just clicked and I figured out they were right and I wasn't getting screwed.
By the way, is there a way to set the dual sim phone to always use data from one line and phone line from another? Or do you have to constantly be switching it somehow?
I also was reading up a bit now and supposedly 5G doesn't work with Dual SIM if you have an iPhone 12. Says you need to turn off the Dual SIM feature to use 5G, then you can switch it back on late to use the Dual SIM feature again.
I have an iPhone 11. You can set it and forget it. It's pretty easy to do. You won't have to worry about it switching if you don't set it up that way. There is an option that you can select if you want it to switch - "Allow cellular data switching." Even if you have this on, you don't have to worry about it eating through you data. It's only on for those rear instances where the free line might not be connecting. I have this on and have never run into any issues.
I am not sure about 5G. I have another free line that is in a 5G phone and the speeds so far are not anything great when compared to LTE for me. But, everyone's location and speeds vary.
