Verification SMS over WIFI
-
Just curious if anyone else has run into this.. I have a counterpart that I helped set up with pfSense a few years ago.
They are in a valley with absolutely no cell service so they rely on their WIFI calling on their Apple IPhones heavily. Suddenly their verification texts from places such as Paypal and Pillpack as well as their bank will not come into their phones until after they travel to cell service. I can however email them *********@txt.att.net and they get those.. (uses SMS according to phones)
Ideas? Ive beat a couple of search engines up about it and so far not getting anywhere..

I see it's been a while since you've posted, but I just wanted to ask if anyone has tried using a different DNS resolver like Unbound in forwarder mode for this? I had a similar issue before and switching away from DNS over TLS helped with some time-sensitive traffic. Curious if anyone has had better luck with VOWiFi and push-based verification codes lately.
