I am not receiving 2-factor authentication SMS messages for different services

vor 5 Tagen

Last month, I moved from Vodafone to Telekom, I transferred also my phone number. I received the new SIM card last week (29.9) and started to use my new contract (the old one with Vodafone expires soon) by switching the sim cards in my phone (Pixel 6 Pro).

I didn't experience any problems, was able to call or receive/send SMS or RSC messages (from Telekom or my friends). But I realized I am not able to login to some services which require 2-factor authentication and sadly only the SMS method. So far I recognize 2 different services. No verification message received from Sentry (comes from US number) or AVI Medical (Hausarztpraxis, number not visible).

I double-checked all settings which were suggested across the forum or FAQ ( APN , SMSC) and all correctly set. 

I suspect, this has something to do with the change of mobile operators as until last day with Vodafone, I was able to receive those messages.

      Hello @haluzator1,

       

      I'm sorry to read that you are facing difficulties with receiving confirmation messages. Are only those 2 services affected or don't you receive any of those confirmation codes via SMS?

       

      Kind regards

      Malte

      @haluzator1,

       

      I see. Unfortunately another try was also unsuccessful. Shall we try again later this evening or tomorrow starting from 11 AM?

       

      Kind regards

      Hello @haluzator1,

       

      I have some more information on this issue. 😊

       

      Please wait around 48 hours and also restart your phone.

      Due to the porting, not everything has been "set up" yet.

       

      Kind regards

      Thanks for sharing your experience. 😊

      Have you tried restarting your phone and toggling flight mode on and off?

      If that doesn’t help, please try resetting your network settings.
      If you're using a physical SIM card, remove it and reinsert it. 📱

      If none of these steps resolve the issue, feel free to reach out to us again and we’ll be happy to investigate further. ✅


      Best Regards
      Luke
