I received prompt and helpful assistance when having difficulty downloading my eSIM. A few simple instructions sent to me by the customer service person remedied my problem. The communication was as polite and directions clear. Thank you.
Fast delivery . Support good. esim perfectly
Picked after comparing many services. This came in as a clear winner when comparing service, quality and very importantly cost. I used the eSIM travelling through Europe and had very good coverage, from the top of mountains to the sea. I took off one star as It wasn’t flawless but I don’t have experience of others, to be fair.
Ordered esim for Japan Got an esim that was very slow. And connects to hongkong.... ip is in hongkong ... that feels wrong. And NO the connection is NOT stable I lost connection so often it was annoying Edit support is nice so I got a refund
Dear Customer, Thank you for sharing your feedback. We would like to clarify the technical side of our service to ensure full transparency for you and all our customers: Technical Setup: It is a standard industry practice for our Japan eSIM data to be routed through a secure Asia-Pacific gateway in Hong Kong. This allows for a stable connection while you are roaming on local Japanese networks like Softbank or Docomo. Data Privacy: We take privacy very seriously. This routing is fully encrypted and is used solely for technical connectivity; no personal data is stored or monitored. Our Response: We value your experience, which is why we provided a replacement eSIM as soon as you reported speed issues. When we realized the standard roaming IP did not meet your specific professional requirements, we respected your preference and issued a refund immediately. We aim to be as helpful as possible, and we wish you a productive and smooth trip in Japan. Best regards, Chillaxsim
Good service and great customer service
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.
Dear Customer, We are sincerely sorry for the connection failure you experienced in Kazakhstan and Uzbekistan. We completely understand how stressful it is to lose internet connectivity during critical moments. We want to take full responsibility. Since the service did not work, we would like to issue a full refund for your order. Please request refund on your order page or email us at [email protected] with your Order Number so we can process this for you. For any connection issues while abroad, please contact us immediately. Our 24/7 support team is always ready to help you resolve them instantly. Apologies again for the inconvenience caused. Sincerely, The ChillaxSIM Team
It’s very affordable, should give it a try
I used the eSIM adapter with a Samsung Xcover 5 phone. Everything worked very well.
SIM arrived within a week (uk) and had slight troubles with the app initially and once that was working I had troubles turning on data but, their service support team are great, responded quick and resolved all issues effectively.
I bought two different packages though easy/fast purchase processes and was never disappointed using them in Athens, Greece. I had 5G in most places and basically never lost connection. My friend was not happy with her Esim provider (another brand) so I recommend her to switch to Chillax, and she did and was happy with her choice as well. I did not try Chillax in other regions so this could be being lucky too so take this with a grain of salt.
Bought a 3GB SIM to get us through Switzerland, where our contacts did not work. Payment was easy, instructions to setup clear, and worked without fault whilst there.
Having made a lot of research on esims and esim card adapters I chose to go with Chillaxsim. Firstly their customer care is amazing. Not only did they reply immediately to my concerns but also kept communication via whatsapp. They confirmed that my phone model (Redmi 8 Note Pro) can take the esim adapter and also shipped it out immediately. Once I received it, I found it a bit hard to use, due to my lack of knowledge. I immediately contacted them via whatsapp and in less than 2 minutes they helped me out and my esim was up and running. Chillaxsim products and services are absolutely fantastic. Well done to the whole team. Will definitely recommend to everyone.
Thank you so much for your kind and thoughtful review! 🌟 We're truly happy to hear that your experience with ChillaxSIM — from the initial support to getting your eSIM adapter up and running — was a smooth and positive one. Our team is always here to help, and it's great to know that our WhatsApp support made things easier for you. 🙌 Your feedback means a lot to us, and we're thrilled that you’re enjoying the benefits of your eSIM. Thanks again for choosing ChillaxSIM and for recommending us — it really motivates our team to keep doing better every day! 💙
Quick and easy and though initially not quite the best price, the coverage and speed means it's the best value. Would buy again.
Best price, easy installation, easy usage, great coverage. I have travelled from Washington DC to Miami, FL and I did not have any problems. I recommend this eSIM service!
We had the Central Asia package and it worked great in all 3 countries. A little more spotty in Uzbekistan, but flawless in both Kazakhstan and Kyrgyzstan. It uses the Beeline network. Would certainly recommend 👍
Hello the esim data Service and Internet connection is really good and fast.
got the esim in fast a min or less, connectivity worked as explained on the web
Internet was working fine in Switzerland.
I'm not impressed a 7day e sim is less than 7 days. I was expecting a full 168 hours of use like my wife's E sim. I don't plan on using this company again Edit: although I appreciate the response, my Wife went with Yuca 7 day e sim and it still works on day 7 for a full 7 days. In fact I'm using her hotspot to tell you the fact it still works. It was activated the same day/time for the same 7 day e sim. That's also how I experienced numerous other sims in other countries.
Hi Brian Thanks for your feedback — and we’re really sorry for the confusion. Our plans follow carrier rules, which count usage by calendar days, not 24-hour blocks. For example, activating on June 4 at 4PM means Day 1 ends at midnight, not the next day at 4PM. This is noted in our email, but we understand it may not match your expectations. We’ll work on making this clearer. Thank you for trying ChillaxSIM, and we truly appreciate your input. — The ChillaxSIM Team
