[Ramadoss]

Hi, I am Ramadoss.N. From Chennai India. I am new to this forum. I have BB 9800 and a playbook.
My play book works fine except the micro sim. The play book was purchased in India from eBay. I bought a sim from Vodafone and it was working. Few months I did not use the play book. Suddenly when I switched on the play book. Cellular net work was not working. When I went to the network page I could not switch on to cellular network and there was a message with error code.
" This phone has been blocked and cannot be used on the network MM#6"
When I installed the sim in another phone sim works perfectly alright. My question is " Do I need Data package to be loaded to browse on playbook" ?.
The sim is a prepaid sim, it has sufficient balance on it.
Appreciate anyone's assistance in this respect.
Thanks
