nexus 5

[Yota]

My internet does not work on my nexus 5. The model is not on your list. How can I fix that?

Hi Yota, it depends on the cause of the problem, but lets check your settings first.
When you get a little deeper in the settings, android-phones look pretty much the same. So please go to the APN settings and check if these are correct.
They should be:
APN: live.vodafone.com
no password of username
MCC 204
MNC 04
verification: PAP
carrier: not specified
Leave all other options empty, save the settings, make sure that the packet data option is checked and reboot the phone (if necessary).
Does that help? For reference you could also check this guide, it should look pretty much the same as on your nexus
