How to fix delayed 2-factor verification codes on new iPhone 16 Pro with Verizon?

New iPhone 16 Pro and have been experiencing selective delays of specific types of emails and texts. On most of my online accounts 2-factor verification sends out a text or email with a code to input. I'm not receiving these in a timely fashion. Most expire in a few minutes and they are not arriving for 1-3 hours later and long since expired. Wireless phone provide is Verizon and I've talked with them and they've presumable done some kind of internal reset. But that has not worked. Any idea?

Thank you. I did contact Verizon again. Got a different technician and once again after a while they said they'd reset something on their end. I also did a phone network reset. Bottomline is that I'm now getting these code texts in a timely fashion. Sometimes they don't come right away and I request a new one and then I get both fairly quickly. And I have received one of the code emails. So things seem to be fixed for now.

I have the same problem, which just started the week of 5/19/25, on my iPhone 15 Pro Max running IOS 18.4.1. My phone service is with Visible from Verizon. Restarting my iPhone always seems to fix the problem immediately, all the old authentication texts come through upon restart. But it doesn't clear the problem, the next request for 2nd Factor Authentication will still not be delivered without another reboot.

Because when you reboot the phone, it re-registers with the network, causing the stacked up text messages to deliver from the carrier.

SMS message sent from 'short code' providers are handled differently by the carrier than "normal" text messages.

This isn't a problem with the phone, it's a problem with your carrier. Contact them.

Thanks, I will try to contact them. But why would rebooting the phone (temporarily) fix the problem? And it only impacts the Authentication texts, not personal texts.
