Pokémon go won't start on mobile data
I downloaded and installed version 0.29.2 of pokemon go on my Android phone, running lollipop. The app works fine most of the time, however, when I open the app without a WiFi connection (with mobile data on and working), it gets stuck on around 20% on the loading screen and doesn't budge.
The app works when I open it with a Wi-Fi connection and then leave Wi-Fi range or turn off Wi-Fi after it has passed the loading screen. However, the app will not pass the loading screen without WiFi. (Edit: Hotspots don't work either)
I've tried all the usual solutions - restarting, clearing cache, reinstalling, turning off and on mobile data. None of them work.
Any idea how I can start the app when I'm not in WiFi range?

Check to see if 'Restrict app background data' is turned on.
To do that for an individual app: Go to Settings -> Apps -> [The App] -> Data Usage
There is a little slider that says 'Restrict app background data'. Make sure it is turned off for Pokemon Go, Google Play Store and Google Play Services.
Make sure they are all turned off. In my personal experience, this solved the problem of not being able to log in without WiFi.

Answer 2
Since Pokemon GO is working with WiFi it must work with mobile data too. This can not be the applications fault, the problem must lie in connectivity of 3G.
May I ask, perhaps you have limited connection? Meaning you have used all the data you had for that month or other time period and now you're stuck with very slow down/up speeds.
If that's not the case then you can try to use the same SIM card in another mobile phone to figure out if your 3G causes the problem.
You can also do a quick speed test to figure out the speeds for your connection.
Answer 3
To play Pokemon Go you must have WIFI on. If you want to play using data, keep wifi on and put on data.
Answer 4
I got this issue in early days, same as my gf, sis and a friend. My gf clean-reinstalled, my sis just erased all the PkmnGo data. All my friend did, was just getting another friend and she turned on her android's hotspot, then he connected and voila, went back to his mobile data and PkmnGo worked like a charm.
