Are there Android fax apps without expensive subscriptions?

I only need to send a fax once or twice a month. Most apps seem to charge weekly or monthly fees. What's a decent option that doesn't end up costing too much?

The pricing is honestly the tricky part. Municorn Fax App offers unlimited faxing on its subscription plans, but that makes more sense for frequent users. I suggest checking https://android-fax-app-reviews.com/ because it also compares pay-as-you-go alternatives. For just a couple of pages monthly, I think comparing the total cost matters more than choosing the highest-rated app.
