Whatsapp doesn't work over 3G,everything else works fine A friend has a factory fresh, unrooted Samsung Galaxy S Duos, and except for Whatsapp every other internet accessing app works fine on a 3G or EDGE connection.

She has un/reinstalled Whatsapp several times. It works fine over Wifi. She's no power user, so any solution involving rooting the phone is not an option. 

To clarify - there is nothing wrong with 3G or EDGE on her phone, since she can browse the internet and use other such apps perfectly fine.

Update - She's on Vodafone, as I and thousands of people in India are, and no, Vodafone is not blocking Whatsapp for any reason.

Searching for solutions on Google only leads to 'No shit, Sherlock!' type answers with genius level solutions like 'check whether your 3G connection is working' or 'get the latest version of Whatsapp'.

So is there a workaround?
I faced similar problem until recently I found the fix. I use Vodafone 3G Pack.


If you are an android user, check the network and settings -> Access Point names
In that check if APN is set to Vodafone Live.
If yes, change it to default settings and it should be changed to vodafone Mobile connect.
Also, then check the value of MCC and MNC. It should be as per country code and mobile operator.


I didnt understand, why this changed on its own, but after making this change and rebooting phone, it worked for me.

I hope this works for you too..
