I have a Samsung Galaxy S3 and I love the new Gmail app. Works awesome. My only problem is that it doesn't sync emails (I don't receive any new notifications when new emails arrive, I have to manually click refresh in the app which is annoying) when I'm on Mobile Data. When I'm on Wifi I receive notifications almost instantly. I've searched on Google Help but couldn't find anything.
I guess I could use the Email app but I don't like that as much as the Gmail app.
What could be the problem?
Just found this thread and it helped me solve the same issue (gmail not syncing on mobile data) on my Galaxy S3. Under settings/data usage/gmail I found that 'restrict background data' was ON. Just for gmail, not globally. Not sure when or how that got checked, but it may have been that way out of the box since my gmail has never synced on mobile data, even with a factory wipe.
Anyways, hope that helps someone else out there.
Ensure that on the device Settings | Data usage | Mobile | Mobile data is set to ON and that if Set mobile data limit is checked that you haven't reached that limit.
Found out the problem. Orange Wap was selected instead of Orange Internet in Settings > Access Point Names.
Are you sure that the Sync option is enabled for gmail?
Go to Settings->Accounts->Google->Your account -> Gmail this last must be checked.
Also check if the Sync option is active at all.
Manage Apps->Search for Gmail app->Clear Data and Clear Cache

Yes, this sync was my problem too...just tried below settings and worked:
Now go to your Account section where you should see all account syncs are enabled :)
It might be caused by a proxy server configured in the APN. See this question: Google apps losing connection to the servers when on mobile data.
my problem was that "google play services" was restricted over cellular network so my emails only synced when i had wifi. Under settings/data usage/google play services...turn data restriction off. This solved my issue.
What was my problem: My emails were syncing over wi-fi connection but NOT via Mobile Data. Application I used for emails are in-built Mail and Gmail apps.
How I solved it:
Now, your emails should start syncing over both - wi-fi and Mobile Data too.
Even after this if you have a problem, then: 1. Made sure that the Data restriction is OFF for your specific app or is OFF in general. 2. Your Data is switched ON and has correct APN configured. 3. Your Background Data usage is set to enable for the specific apps.
If none of the other things work, go to Apps > Google services framework. Click Clear cache and data button. Then, reboot.
My Phone Galaxy S4:
On mobile network only my Gmail app was not pushing automatically, gmaps was slow, youtube was not working or really slow and Calendar wasn't syncing.
After looking on the internet I was not able to find the solution. I have tried everything that was simple like clear cache, reboot, sync OFF/ON ...
But finally with this site I come up with the APN reset solution. I did it and also I have found that google services had the check mark ON for restrict background data. Setting/data usage/google services
I have never touched this option before so I don't know why it was checked. After these two steps my phone works perfectly now.
I went through every item under data usage to check for restrictions. For me it was Exchange Services that was restricted. Solved. Thanks.
i had the same problem in samsung galaxy J5 running lollipop ( 5.1.1) . I had to enable following under the Settings/Data Usage/Background data 1) Email 2) Gmail 3) Google Settings
I had initially only enabled 1 & 2. Yahoo email was working but Gmail was not. Once i enabled Google Settings , the Gmail sync also started working.
