Clauses that are "Sata" versus halakhic liability in contracts

I am considering purchasing a SIM card for my 9-year-old son and before signing, I read the terms of the agreement. One of the sections states:
“Do not transfer the SIM card to a third party. Do not connect the SIM card to a switchboard, any machine, software for distributing messages/notifications, websites, a computer, and the like.”
In practice, the card is intended for use by my son (who is, formally, a third party), and sometimes we use his device as a Wi-Fi point (Hotspot) for occasional use on a computer. As I understand it, the purpose of the section is to prevent commercial/systemic uses or mass distribution, and not to prevent a parent from providing a line to their child or occasional use as is reasonable at home.
I would like to ask for halachic clarification:

1. Given the principle of dina demalkuta dina and the obligation to fulfill contracts, is such use considered a breach of obligation that must be avoided?
2. Can the aforementioned section be seen as a general “section 578” that does not apply to normal home use, and in any case, there is no halachic prohibition against providing the line to a child and making occasional use of it as a Wi-Fi point?

I would like to emphasize that I do not fear any significant legal implications in these circumstances; my question concerns the halakhic obligation required of me.
Thank you in advance for the guidance.
