Trip to Panama
Trip to Panama, purchased unlimited internet for our 2 week stay. Easy to set up and once we arrived it immediately hooked up to there towers.
No issues with service, always ready to use, no problems, even used to watch Netflix shows. Will definitely buy again on our next trip, can’t beat the price and peace of mind it provided.

UBIGI in China
Quick and easy installation and everything worked as I imagined. The only thing that is not ideal is the Hotspot, which is slow and when sharing on NB you have to wait a long time for the data to download.

Very happy, a bit slow in the mountains
We have used it for ten days an it’s a lot of data for the amount for money that we spent. Some players around the mountains in Nagano it was a bit slow. But also understandable.
