Caller ID new Wireless Home Phone

Which device did you switch to? And when you say modem, do you mean the wireless home phone device itself, or your internet modem?

The caller name only shows up if the device supports that feature and the caller's network sends the name along with the number, otherwise you just get the number. Since it started at the same time as the device change, it may be that the new one isn't certified for name display at Koodo, i'm not certain though. Did the name show for those same callers on the old device? If you still have it, hooking it back up for a few minutes would confirm where the problem is coming from.

wireless home phone modem nubia wf725ca. Already registered new sim to new wireless modem and original phone number. No Don't want to mess around with reverting to old sim and old modem.  Koodo service is call display +. Previous name does not appear neither does time stamp.   Other people here have had the same modem change done and I wonder if they experienced this issue.

Koodo provides the modem to connect to cellular network, it should have Call Display+. However, the phone that connected to the device might not fully synced / compatible with the new device, Can you reset the phone to its factory default ?

Nothing much to reset other than power off, wait to reset memory.  Could be the memory is defective.. it stores the number though. I bought another call display phone with less features and date and time  does show with the number. Strange that it would fail once i changed the modem
