Zensim so easy to use in Europe

Im in my 60's and found the purchase, set up and experience with Zensim brilliant. Easy to download the app. All instructions were clear and very helpful. Would recommend to anyone who wants to keep their phone number and travel with ease.

The best telco and travel esim company!

I have been a customer of zensim for the past few years, not only has their mobile service been outstanding and incredibly cost effective but their travel esims have saved me so much money on trips. I have had minor issues (on my end) at times and their customer service has always been prompt and comprehensive. It is great to see an small australian company making an impact in the telco space. Keep it up guys!

I’ve been using Zemsin for my mobile…

I’ve been using Zemsin for my mobile data, and honestly, I’m really happy with their service. The connection has been reliable, and the speed is great for everyday use like social media, maps, and streaming.

One thing I really appreciate is how fast and helpful their customer service is. Anytime I’ve had a question, they’ve responded quickly and made everything easy to understand.

Overall, it’s been a smooth and stress-free experience. I definitely recommend Zemsin to anyone looking for a simple, efficient, and trustworthy mobile data provider.

Impressed by new eSIM

I don’t usually write reviews but was quite impressed by how good this eSIM was in Japan. I have used Airalo many times before but faced intermittent connectivity issues which is why I wanted to try something different. I had a much smoother experience with ZenSim. If you’re reading this, I’d recommend this eSIM :)

I've been using their SIMs for months…

I've been using their SIMs for months now as I travel around the world and they provide great coverage. Their customer service is hands down the best I've ever experienced and the fact they have such an easy to use app is perfect. Would happily recommend others use them as well
