Hey everyone, I'm looking for a broadband provider (ideally fiber) that can be put on hold when not there, i.e. every year the user is only there 4-5 months, so no use in paying for the whole year.

Both putting it on hold (maybe at a lower fee) as well as cancelling and making a new contract next time would be ok.

Are there any options out there?

Do they have any fair use policy?

But do they allow you to suspend for months when TS is not around to use it?

But for long term use there is a risk the plan might change.

Maybe I did not make it clear enough. It is definitely ok to subscribe and terminate anytime since no contract.
Only  thing is that the plan might change from time to time, but hopefully they continue to offer such plan for many years to come.
