I’m about a month into trying to get support from Fonus and I still don’t have meaningful answers to basic questions. Messages sometimes go unanswered for a week at a time, and most replies just repeat the Fair Usage Policy rather than addressing what I’m actually asking.

I wanted to like Fonus because the pricing and “international unlimited” concept is really appealing for travelers. When it works, it’s convenient to have one plan that’s meant to function across countries. Unfortunately, my experience has been that “unlimited” comes with throttling for “excessive use,” even when you’re using the service normally on the go. They say my line was throttled for “excessive use,” but they won’t clearly explain what specific rule I supposedly violated beyond “high data usage” on an unlimited plan. The biggest issue is that they appear to throttle once you hit some internal data range, but they will not clearly specify what that threshold is. I repeatedly asked: when does throttling happen on the unlimited plan, what is the internal limit, and how can a customer stay compliant—and they just don’t answer.

Customer support has been the most disappointing part. It has taken weeks of back-and-forth to get no meaningful responses, and many replies just repeat talking points without providing clear, actionable guidance on what level of data use triggers throttling. I’ve also had issues with core plan features like calling—my number has not worked reliably when I needed it—and at one point my service stopped working entirely while I was still trying to get answers.

If you’re a very light user and don’t need dependable support, it might be okay. But if you rely on predictable data while traveling, need your phone number to work consistently, and expect timely customer support, I would be cautious and consider other options.
