Access Point pop up on Lumia 620

[Bramha]

I started getting the problem recently on my Lumia 620. I am using this phone from past couple of months with Vodafone 3G and was working good. Last week the phone felt down from a table from height of two feet, fortunately there was no damage to the phone, neither any of its internal functions but i started getting a strange problem as mentioned in the title above.

My phone now keeps asking for access point every now and then for my 3g data. But the funny part is even though i cancel the message, i can still access my internet comfortably. Is it because the phone felt? How can i get rid of this message?

You should first turn off 3G data, go to settings and delete all access points available. Restart the phone and create new single APN for your 3G network. Or alternatively get it from your network provider. Thats it. Now you wont be getting that pop up again.
