Is it allowed to use Tesco Mobile for browsing the web on a laptop?

Christian Peters Asked: Is it allowed to use Tesco Mobile for browsing the web on a laptop?

Im not too sure if it breaches the contract in any way.

It does say:
3.1 Inclusive Credit can be used for:

(a) texts sent in the UK to UK mobiles,

(b) GPRS browsing on the mobile internet in the UK

I am not to sure if that means only on a mobile.

Then although it says

4. Inclusive Credit and Data Charges

4.1 Inclusive Credit can be used on GPRS and 3G networks (as applicable to your handset), for personal internet use via your mobile phone whilst you are in the UK.

AND

You may not use your SIM Card:

(a) in, or connected to, any other device including modems;

(b) to allow the continuous streaming of any audio / video content, enable Voice over Internet (VOIP), P2P or file sharing; or

(c) in such a way that adversely impacts the service to other Tesco Mobile or Telefonica O2 UK customers.

IF it is not allowed and you still do it, will they know?

Please only answer if you are sure, thank you in advance.
