iPhone 4 has 3G connectivity but can't access internet Just last week, my access to the internet over mobile data networks has stopped working. I've already talked to my operator, and they gave me a new SIM card and tested that 3G works in another phone with it.

Basically the operator is expecting this to be an antenna failure, which seems odd as I still get full connection bars, WiFi works flawlessly and my 3G does transport e-mails, just nothing else (like opening websites). 

I do have 21M/2M speed, so the connection isn't just clogged.

Does anyone have any idea what this could be?

If nothing comes up, I will probably have to get a new antenna and install it myself.

I've discovered that SSH connections are working on 3G. This is becoming really weird...
Settings -> General -> VPN (should be not connected, if this is a personal device)
Settings -> General -> Cellular -> Cellular Data (turn off, reset the device) 
After the device boot-up 
Settings -> General -> Cellular -> Cellular Data (turn on, reset the device) 


IF that doesn't help (follow this )
