Duel sim data roaming not working

Hello, I am an expat from the US now living in Germany. I got a Telekom (German phone plan) esim which I have now activated on my phone. I went through the set up steps in this video. The calling and texting is working great, however the data roaming isn't working. For example if I'm off wifi I can make calls and send texts (even on WhatsApp) but for some reason I'm not able to google things, look up directions, etc. Does anyone have any ideas what the problem may be?

iPhone 14, iOS 16

If you are sure the problem is the Roaming itself and you have enough data, the issue might be that you didn't enable Roaming in settings yet.


To enable Roaming;

  1. Open Settings
  2. Go to "Mobile Data"
  3. Click on the phone line you wish to enable Roaming on, and enable Data Roaming
