I used to be able to see caller ID information for certain numbers (in my contacts) and now they show as "private number" (as of 2 weeks ago). I can't find anything under settings that may solve the issue and I know those contacts don't have their numbers set as "private", as they do show up on other people's phones. My phone is the LG G6.
I have been in touch with Koodo and though it has taken some work on their end to figure out what was going on I have resolve. I did have it working again after they did something, for a couple of weeks and it started again. But seems to be all fixed now. And if it happens again I will just phone them back. Koodo is Awesome I really really love this company.
Update: My LG G6 did an Android system update today. After the update, the phone re-started and it asked me if I wanted to be able to make calls via wi-fi to which I said "no". That fixed the problem. I am now able to see the caller ID for the numbers that were showing as "private". The system update also allowed for the Emergency Alerts to be enabled to this phone.
