No internet service for more than 24 hours

Hi<br> <br> since 8am on the 25th February and till now i have been unable to access the internet. I can make and take calls. I am receiving those annoying marketing smses. I am able to send and receive emails. I have taken out the battery from my phone countless times. I have even put my Sim Card on another phone. But still nothing. No Service. And this is in different locations also so it cant be that the one area has poor network.<br> <br> Like what am I to do. i cant even google stupid stuff. I get an email and it says click here for more details and i cant even do that.
