Waste of money
Used Chillaxsim on my trip through Kazakhstan and Uzbekistan. In Kazakhstan the signal constantly dropped, internet was unstable, and in Uzbekistan the network disappeared completely. I had no connection in critical moments and had to buy another SIM card the next day. I used an iPhone 16 with eSIM and followed all standard troubleshooting steps (restart, roaming settings, network refresh, etc.). The issue was NOT caused by my device or setup — the service simply did not work. Total waste of money. I will never use this provider again and I will not recommend it to anyone.
