I’m curious to hear if you see any change from that.
I’ve gotten this nagging suspicion that carriers have started swapping SIMs like PC supporters used to recommend rebooting Windows. When you don’t have a clue what the underlying problem really is and you cannot (or do not want to) investigate in more detail, you need a good catch-all. At times it feels to me like carriers have resorted to swapping SIMs as that catch-all.
Complete guess here, but reading this did remind me of something I hadn’t used in years.
There used to be some magic *XX key combo that would update carrier settings, though looks like you can do it through the iOS UI now. It would fix a myriad of problems having to do with connection, especially in the more rural areas I was usually in.
Note the Apple page mentions that a new SIM requires reloading the carrier settings, so perhaps swapping the SIM will fix the problem, while underneath the carrier settings were also updated.
I only had to wait a day to test – and my iPhone failed to receive the alert while the other phone did receive it. Again – both iPhones use Verizon and are on the same plan. Both phones are in the same location and have identical settings.
I’ve done a lot of searching online about this topic and it seems to happen to a lot of people and is not confined to any one carrier. I’ve tried all the offered solutions but nothing seems to really work.
I continue to educate myself on how WEA works. After browsing FCC and FEMA sites I found some interesting keywords defining the different levels of WEA. Plugging those terms into a search box found this informative article from Verizon:
For the events of the past few days (Flash Flood Warnings) we have been outside – but close to – the boundary. So my iPhone SE3 has better geo-targeting than the iPhone SE 2016. That may account for why one phone but not the other receives alerts.
For the previous events (fast moving wildfire) I do not know where the geo-targeting boundary was located.
I now know more about WEA that I ever thought I would need.
