UPeSIM スイスで接続を維持

I've used upesim 3 times now across different countries and it has worked really well! Any issue or question I had was answered within minutes by customer service via email. They even helped me out to switch packages when I accidentally selected the wrong country.

Altough I was unable to activate the service (likely due to an issue on my end), the support service was possibly the best I have ever received. Axel replied to all my messages in real-time, and has shown absolute patience and understanding for my issue. If you're reading this, know that you're safe with this company!
