Right. You are both iPhone so text is just iMessage which doesn’t actually us Verizon whereas a call does use Verizon. On the other hand you would be able to FaceTime her for the same reason.
Phone numbers are provisioned in a round-robin fashion amongst a cluster of servers responsible for 5G broken out by application. Very basically, each service a carrier can offer (call waiting, call forwarding, over the air programming, voicemail, etc.) are application servers on the backend. All subscriber data is stored in a database called a UDM/HSS.
When your phone powers on, it sends a registration message which includes your phone number and serial number (IMSI) over the cellular or wifi network which gets routed to the HSS for validation. If it's valid and has a corresponding record, your device shows service bars, if not, it doesn't show service.
I would suspect that there's something wrong with the validation of subscriber identities in one or more HSS databases which is why two devices in the same physical location have different behaviors.
Anyone have any idea how popular Downdetector is? Ratio of DD outage reports vs. actual Verizon outage size?
All news reports all day long have been harping on Downdetector peaking at 100,000 and quickly dropping to 50,000 reports. Most news articles are then misinterpreting this data as 100,000 outages that dropped because Verizon has restored services to 50,000 people. In reality, most people that were inclined to file a report with Downdetector have already reported, so number of reports will naturally drop off whether service is restored or not.
For example: if only 1% of affected users are reporting to Downdetector, then there are 10 million affected. Anyone have actual data or reliable estimates of Downdetector's typical reporting ratio?

Very few people use it. This affected over 50 million.
Well my wife and I are now back up. Arizona here. Hopefully others are coming back up now or very soon.
Still out for in SF as well. Out on my S24 Ultra and iPhone 16 Pro Max but working fine on my iPad 13” M4
It came back for a few seconds then went away back to SOS on iPhone while on S24 Ultra showing Emergency Call Only
Things are starting to work again for me in the Denver metro area. Reboot phone, got signal again, was able to make a call, missed texts are slowly trickling in. Voicemail seems to be down though. Total downtime for me was 7 hours
