Yeah, I tried lots of possible solutions. None worked. I wanted to avoid clearing my Recent Calls list, but from what I was reading in a number of places, that would be the real solution. I called Verizon. They claimed there was some setup problem with my SIM and they got it fixed, but that did not fix the issue. So what I did was just delete each entry in the Recent Calls list that was for the person I was trying to call. Voila! I could call the person without the error. (I'm still not sure what would happen if you let it call with the "remaining line.") Anyway, that proved to me that clearing the list is the solution and I'll either do that or use the "one at a time" approach. Just wanted to mention that so others would know this optional solution.

I see this message almost everytime I call someone from my Contacts or my Recents list. I just touch "call" and the call goes through. I'm not seeing any additional lines on my AT&T bill. But it's annoying. And I don't want to delete my Recents list. That's a workaround for a issue this phone shouldn't have.


This is a new phone, 13 Max Pro, online for 1 month. My last phone was an iPhone 6 Plus (that's right, 6). Same phone number I've had since 1998. This new phone was extremely expensive and I am hoping Apple will fix this issue soon.
