Yes, but go to settings - more - Mobile networks and create a new one and enter these settings. Ignore the part where it tells you to call att. Just enter the settings where it says apn in these directions

When I got my Nexus 4 all I did was put in the SIM from my iPhone and everything worked fine. Never had to change APN settings to get mobile data, it just worked out of the box. Are the APN settings in the link better in any way?
