My apps don't have access to my mobile internet I have a very weird problem with my phone. I don't have mobile internet on any of my apps, but I can surf the internet with no problem when I am using my browser. I think it is good to mention that I am using the browser which comes with android operation system. 

When I am connected to a wifi network, everything is fine. The problem is only with my mobile internet. Can someone tell me where the problem may be?

I am using HTC WildFire S. Android version of the phone is Android 2.3.5. The phone is very old and this is the final version that I can update.
There could be several reasons


Check your device's date if it is set for today.
Try to reset your Internet settings that is access point settings
Make sure that you have enough memory
Clear catch and app data for that particular app
Try restarting your device two or more times
Make sure you have the latest updated apps


If any of the above does not work unfortunately I have to say that you need to reset your device. Let us know which one of above solution works for you
