pay per usage?

Is it possible to have a pay-per-usage SIM card, without any monthly plan?.. I just need a telephone number to be able to answer my door intercom.
If the pay-per-usage is not available, I would like to know if it's possible to add a telephone number to my internet plan (30Mbps).
Thank you for any help
