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.

I ran into something similar before and found that using an sms api helped a lot. If your phone's carrier supports Wi-Fi calling and texting, but verification texts still don't come through, sending the message using an sms api through a server with proper routing can sometimes bypass that issue. Worth checking if the issue is more with how the text is being sent rather than your end.

@Duncantr The mesh AP system they were using appears to be the culprit behind it.. Once they set up an old Linksys WAP in their office the texts began coming through.
Not sure what that system was as they handled that part themselves. I was just their network guy.
Thanks for the response! Much appreciated.
