Can I buy seasonal/PAYG wifi for holiday home?

Hello, we have a summer flat in the north of the island and need Internet connection primarily for the smart TV, so the kids can watch some cartoons.

Does anybody know or use WIFI which is just for a few months of the year? We aren’t here for about 8 months/year so it seems a shame to pay for all the time we’re not using it.

Any help in advance would be much appreciated! Thank you
