Can I buy Wi-Fi for a month?

Excuse me, I'm curious about something regarding Wi-Fi services. I've been wondering if it's possible to purchase Wi-Fi for just a month's duration, rather than committing to a longer-term contract. I'm looking for flexibility and want to ensure that I'm not locked into anything too rigid. Could you please clarify if this is an option and if so, what steps I need to take to arrange it? Thank you for your assistance.
