The user below helped me figure out how to access settings! If you have a new phone and need to log on to your old city, or if you just need to access settings, make sure SimCity Buildit app is completely exited on your phone. Then turn on airplane mode. Then open simcity buildit. Play the new city/tutorial until you are able to visit Daniel's city (maybe you don't need to play that long to get the advising bubble to pop up, I'm not sure). Then travel to Daniel's City. Then return to your main city. Eva might pop up at this point with an advising bubble advising you to save your game to avoid losing progress. Or, you might need to play longer until she does. Tap on that bubble and it will take you to settings. Turn off airplane mode to regain internet access. Then you can do whatever you need to do in settings.
