    The connection in Thailand was amazing BUT
    The connection in Thailand was amazing, and I had absolutely no issues. However, I purchased the same eSIM for my trip to Japan, and the experience was quite disappointing. I contacted customer support by email, and they provided troubleshooting instructions, but unfortunately, the issue persisted. Every time I wanted to use my phone, I had to turn airplane mode on and off just to get the connection working. This was very inconvenient and frustrating, especially while travelling. I expected a much better experience, considering how well it worked in Thailand.

    Recommended!
    I used Ubigi during my trip to two European countries—Romania and Greece—and overall, it was a very positive experience. In Bucharest, Romania, the connection was absolutely excellent, fast, and completely seamless from day one. In Athens, Greece, I did experience a few occasional network dropouts, but overall the service was still very good and kept me connected when I needed it. Setup was easy, and it’s a reliable option for international travel. Recommended!
