Ok, if it still does the same without the software, that means it has
to be the equipment.....
A few questions which should tell you what the problem is so you can
get it resolved.
1) Is the SIM more than 18mths old? (Older SIMs can cause problems with
new cards)
2) Does the same happen if you put the SIM in a mobile phone and access
the internet?
3) Is the problem area specific, or does it happen everywhere? (As if
it happens everywhere, it will not be the network)
4) Have you tried your card in a different laptop? (If your not able to
do this, a Vodafone store should be able to help you out)
Once you have the answer to these, either go into a Vodafone store or
give C/S a call, and they should be able to help out.
