Frequently asked questions

Does Ubigi have unlimited plans?
It has monthly "unlimiteds" in selected countries, generally with a fair use policy. Its main catalog is per GB.
Is Ubigi reliable?
Yes: it is backed by Transatel/NTT with solid technical coverage. The comparison with VoaSim is about the data model (per GB with a counter vs truly unlimited) and what backs you up if something fails mid-trip.
Which one for a 2-week trip through Europe?
With normal data usage, VoaSim's 15-day unlimited (USD 42.90) removes the counter and the top-ups; on Ubigi you would need to estimate 20-30 GB for the same comfort.
