I put $10 on an account over ten years ago to make sporadic calls (e.g. customer service in other countries). That account still has $5 left, and I’ve made a ton of calls to many different countries. What’s a good alternative here? I just want to make outgoing international calls cheaply.
From a bit of Googling, Viber may be a reasonable alternative. They're owned by a reasonably non-shady/non-fly-by-night operation (Rakuten), have a desktop app, and let you buy credit without a subscription: https://account.viber.com/en/rates-index
Happy to hear about experiences with alternatives.
