iPhone 13 Pro Max SMS Issue. Cant receive second authentication via text

I am having the same issue, I have been to Apple Store, and Verizon 3X, no one can help me it seems, I am going to trade the phone in for something else. I have tried to get Venmo to help, and they cannot. What can I do? Has anyone fixed this problem and can share what they did? Thanks!

Not sure this will help your situation, but I contact my carrier (T-Mobile) through their website chat function. Explained the issue. The tech fixed the problem in about 15 minutes total after checking my phone line. No idea what he did, but it works now. One more reason I love T-Mobile!!

Had same issue, got fixed by my carrier tech support “RSA” is the keyword, resetting a switch or something.

approx time 20 minutes.

identify apps you want to use while troubleshooting and choose once which are ok if you are locked out just in case..!!

Thanks for the replies. This was so frustrating I spent another four hours in a Verizon store and got a new phone completely and it didn’t change the fact that I couldn't receive verification texts from my apps. Finally I got referred to the Port Center These are the people that change your number from one carrier to the other. The Verizon Port team was able to connect me with with someone on their team that was able to identify the problem. Basically when they ported over my number they had to manually activate a button on their end that allows texts from androids and Apps to port over as well. Allegedly this should happen automatically at the time of the port, but for some reason it did not occur when my number was moved from Xfinity to Verizon. So they “flipped the switch” manually on their end. Now it works perfectly. Not an Apple issue. Deal with your carrier on this one.

I had the same issue for a couple months. I thought it would take a while to get it fixed by calling AT&T and it was such an easy fix. Works great now!

I contacted AT&T just now with the same issue on my 1-mo old 13 pro and the rep said there is no such thing as a Level 2 Customer Service to uncheck the setting "Send emails as text messages". She looked at my acct and asked for the IMEI and ICCID #s to check my phone and found that it was a SIM card issue. She said if we get disconnected while she resets it, to turn off and turn back on my phone. I tried it, connected to the site where a 2FA was needed and IT WORKED!!!

One issue for me was messages were selected “on” to download to the cloud which caused a delay. Go to Settings-Your Name-iCloud and uncheck “messages.”

if you do cloud backups then your messages should be saved that way without causing the cloud delay every time a message is received.

I purchased My IPhone 13 in September 2021 and as of today I have used the digital SIM card but now( after an update 15.4.1) it is not receiving notification texts and I was told that I needed a SIM card due to a network issue. After 2 hours at an Apple Store and 45 minutes in T-MOBILE my phone is experiencing the same exact issues.

Please advise

I am having the same problem went to the Verizon store and basically person told me that it isn’t Verizon .I’m not receiving my verification code via SMS I am very frustrated did not have this problem with my prior iPhone feel I will need to return phone.

Do not bother with folks at a /Verizon store. They generally do not have sufficient technological experience. Contact the Customer Support people directly at Verizon through their website. They should be able to help you. I had same problem and got solved by T-Mobile Support people.

Sorry … “affirm or robin” ???
