ByteSIM eSIM - Data Plan

Disappointing experience during a 20-day trip. I purchased a 20gb data plan with unlimited calls and texts, but experienced repeated call drops mid-conversation across 7-8 different phone numbers, with multiple failures happening on the same day. I also had sudden network outages where I couldn't connect to the internet for several minutes at a time throughout the day. When I contacted customer support with detailed evidence (screenshots of dropped calls, specific phone numbers affected), they were dismissive and repeatedly blamed "signal conditions on the receiving party's end" despite the pattern occurring consistently across multiple different numbers and days. They refused to acknowledge it could be a service issue on their end and denied any refund. The unreliable calls made it genuinely difficult to make reservations and communicate during my trip. If you need dependable voice calls while traveling, I'd look elsewhere. calling feature they advertise as "unlimited talk" was unreliable when I needed it most.

I was using bytesim in Asia and it worked well, but in Europe and Mexico the internet is so slow that you can’t even open the app
