can my tablet get blocked if its on a contract?

Hi,

I suspect my tablet is on a mobile contract. If the bil payer does not pay the bill can the network lock the tablet. Or if I quickly get it unlocked would that stop this from happening.

Thank you

On the back there is a really small sticker that says,  Sony Mobile coms about se221 88 LUND SWEDEN

That's definitely the customization number the only firmware I could find is,

Touch firmware version:

7

Is it definately a Z3 Tablet compact as I find nothing listed for that item or it's variations
