Decision guide
When does unlimited make sense?
Choose unlimited if you...
- + Stream video or music daily
- + Work remotely with video calls
- + Use 10GB+ per week
- + Want predictable daily costs
- + Hate monitoring data usage
Choose fixed data if you...
- + Use under 5GB per trip
- + Mostly use maps and messaging
- + Want the lowest possible cost
- + Need full-speed hotspot tethering
- + Travel to Nomad-covered destinations
Fine print
Fair use policies explained
Holafly's unlimited plans come with a fair use policy. After you consume a set amount of high-speed data per day (typically 1-2GB depending on the country), your speed drops sharply for the rest of that day. The counter resets at midnight.
At reduced speeds, you can still send messages, use maps, browse text-heavy websites, and make VoIP calls. Streaming video, downloading large files, and video calls will be slow or unusable until the next day's reset.
This is common practice among unlimited mobile plans worldwide and does not mean the plan is not unlimited. It means you get unlimited data volume with a speed cap after the daily high-speed threshold.
