ZenSim

Zen eSIM was fantastic for my Asian holiday. Went to Thailand, Malaysia, Singapore, Sri Lanka and India and I had zero trouble. Highly recommend! Shall be buying again for my trip to Japan. Show details

I purchased a $35 digital E-sim for the duration of a 5 week stay in Europe and was happy that it served my purpose. I'm not a heavy user of social media etc. so the $35 fee was adequate for me and was much cheaper than many other E-sims on offer.… Read more

My enquiries were answered promptly when I had one or two enquiries. Would be happy to use ZenSim in future.

I used ZenSim on a recent 6 week trip to Spain. On arrival in Barcelona I had some issues with activating the ZenSim. Being an older traveller and not very tech savvy I immediately contacted the ZenSim help desk by Wifi email. Fast response to my… Read more

initial email and a couple of emails later and I was connected. Excellent assistance. Absolutely no issues during the rest of my trip, which included a top-up in Hong Kong. Would definitely recommend ZenSim for overseas travel and will never travel without it again. Thank you Josh and Andy for your help.

Outstanding service from ZenSim, even at 35,000 feet I had an excellent experience with ZenSim while already mid journey on an international flight. I’d purchased a EU multi country unlimited eSIM, activated it on my Samsung phone, then managed to leave that phone behind in an airport lounge before reaching Europe. Not ideal. I contacted ZenSim… Read more

from onboard WiFi from my tablet, fully expecting a slow or limited response given the situation. Instead, they replied quickly, clearly understood the issue, and took ownership of fixing it. They explained the limitation around eSIMs already being installed, then proactively recreated the eSIM and issued a brand new QR code so my wife could install it on her iPhone instead.

No arguments, no fine print, no run around, just practical problem solving and genuinely helpful service. The replacement QR code arrived promptly with clear instructions, and everything worked exactly as promised.

This kind of customer support (thanks Josh) especially when you’re travelling and already stressed, is rare. Based on this experience alone, I’ve continually recommended ZenSim to family travelling on overseas trips, and I wouldn’t hesitate to use them again.

If you’re looking for a travel eSIM provider that actually backs their product with real service, ZenSim is the real deal.

During a recent 6 week trip to Ireland, England, Norway, France, Switzerland, Germany, Austria and Singapore my husband and I both purchased a 30 Day x 20GB Sim Card. My husbands SIM activated immediately on arrival in Ireland, mine took a little bit of investigation but eventually got it through. Once set up no hick ups at all. We has a very… Read more

eclectic holiday from the wilds of Ireland to the top of Norway. We were out in the North Sea using the ships wifi, but as soon as we were onshore and out of range of the ship our Sims would activate. Onward into the Swiss mountains with no issues, the same for Germany and then the Austrian Mountains. Before we departed for Singapore we purchased a small 10GB Sim to cover us in Singapore as it was a different region to the European one. Again no issues. Absolutely recommend, we will use again as the service was fast and reliable. I do suggest you copy Help Information into an email to yourself in case you encounter issues with the initial activation. Just means you may avoid having to find free wifi to access the website to troubleshoot.

ZenSim - a seamless experience – After receiving many ads from them regarding their launch, I wanted to give them a go as I want nothing more than to help my fellow Aussies in a start-up. The plans that they have on offer are good value for what you get especially with the uncapped speeds being the cherry on top unlike other MVNOs. ZenSim uses the Vodafone network; however, I… Read more

had no issues regarding reception and the speeds have been satisfactory.

Customer service is excellent as they were very prompt with resolving an issue. I had an issue upon activation of the service where the 5G was not configured properly, they communicated updates of what was going on their end and gave me clarification of what had happened which I appreciated.

For those on the sustainability front, it's great to know that they are doing their part to save our environment by contributing 2% of their profits to the Great Barrier Reef Foundation, having the team work fully remote and working with Carbon Positive Australia to replant native trees across Australia.

I highly recommend giving them a go as I doubt you will be disappointed.

Keep up the high standards ZenSim Team and wishing you all the best as you grow as a company.

So easy all round. Purchased online and set up within minutes. Have used Zensim in both Bali and Singapore and had data available where ever we went. Traverlling to China shortly and 1st stop will be Zensim Show details

Love the plain english feel of the website. they are very responsive if you have any questions or difficulties. Have used the travel sim and the roaming travel options as well. A few difficulties with functionality and the help desk were amazing in resolving them Show details

Once I got my eSIM activated it was great for me. It was a little clunky to start with but the help I received was terrific and got me on my way! I will use this eSIM again Show details

In most the service was great. Easy to install and activate. It did however drop out once or twice not sure why whilst in Bali. Just be aware that the service does not work during Nypie day. But like I said all on all good.

Setup was a breeze, literally "plug and play". Happy with the coverage, no issues in all the countries visited: Belgium, The Netherlands, France and the UK. Loved that there was the option to top up using the app. From my experience it was value for money and will be using again in future.

ZenSim’s eSIM 35GB Monthly Plan is very affordable, installed automatically using the ZenSim app and worked seamlessly. Kudos to ZenSim! I highly recommend choosing ZenSim for your Aussie eSIM in future. Show details

I found ZenSim very easy to understand being a first time user and not being part of the younger generation used to using an eSim card. Very understandable instructions on downloading the app. Great price easily available when needed although I did overestimate the amount I would need but will definitely be using again when I next travel. Show details

I've only just signed up - so time will tell if Zen Sim prove truly 'zen' in the longer term! But so far SO great. There was one issue during onboarding which was sorted out at lightning speed by Zen Sim's support team who were very easy to reach. I'm super happy to have made the switch and looking forward to trying them out. Edit on 23/03/2026:… Read more

Zen Sim reached out to me today (approx. two weeks after the above review was written/submitted) offering a credit in exchange for a review (regardless of a positive or negative review). While I wasn't incentivised when I originally wrote this review, I'm disclosing the credit for full transparency.

I bought zensim for a trip to the USA. After installing on my pixel and activating after landing I didn't have to think about signal or rates for the whole trip. It worked seamlessly. I definitely recommend to anyone looking for a network solution for your trip. Show details

Great eSIM from Australia. Initial setup steps (due to settings on the phone) are a bit tricky. Read and follow all steps - this is also for confirming your identity so don't use aliases. After setup, it works like a charm and I can now just top up and get on the plane to the next adventure. The price difference compared to roaming is significant and don't look for a sawing of a few dollars, just go with one you can trust. Show details

Simple and straightforward on-boarding as a new customer with a number transfer. Service in first month has been as expected. Ability to data bank along with referral incentives are great features. Show details

Outstanding customer service and the app was so easy to use. We were connected and had service while we were still in the airport queue, very impressed and highly recommend. We've used ZenSim twice now on a trip to Europe (Spain, UK and Ireland) and to Indonesia. No issues at all with reception or coverage. 20GB was more than enough for us for a… Read more

month of using maps, researching destinations, buying train tickets, using social media and WIFI calls/ texts (without streaming). Happy Travels!

The customer service from ZenSim is absolutely fantastic. Nothing is too much trouble. Very easy to use and was highly reliable on a large trip through Asia and Europe. I am looking forward to using them again for our next trip. Show details

Zensim global provided excellent service in USA, Colombia, Brazil, whereas the competitors global product chosen by my husband provided no coverage in Colombia. There were no drop outs with Zensim Show details

Travelled to China for 3 weeks and Zensim never failed. As we travelled from city to city, Zensim automatically connected to the new providers in the area. Zensim worked so well, even in areas where international roaming by large telcos did not. Data speed was acceptable most of the time, even when using for video calls, with the slower speeds… Read more

caused by the local providers. The Zensim team are always available to answer any questions. Cannot recommend highly enough!

it was easy to setup and worked perfectly for a recent trip to the US. In fact, this was the second eSIM purchased, the first one was from another company and I could not get it to work at all. We used ZenSim for in-car navigation and the speed was great. Show details

Much cheaper than roaming! E-SIM was very easy to install (on iPhones running iOS 26, installation, as well as activation once in the target region, were automatic). Coverage was fine, I did not download much other than email but I had no issues with coverage/speeds and neither did my family members. Pleased with the product - good alternative to expensive roaming charges if one is happy to be without a cellular voice line. Show details

I like purchasing eSim from ZenSim for the fact it's easy to buy online, easy instruction to follow and automated activation after arriving to the destination country. I went to Indonesia for 30 days and I used it without hassle for internet data as I bought 'Indonesia Unlimited STANDARD - 30 Days' plan. I could share internet data from my iphone13 to my macbook through this eSim with no issue for my whole trip. Overall I love it. Thanks. Show details

Top ESIM for Travel My partner started using ZenSim 6 months ago and loved it. I bought myself a ZenSim for my European Christmas travel and it worked seamlessly through Turkey, Hungary and Germany. I will be using ZenSim again for my UK trip later this year as it’s easy to use, economical and is supported well. Juls Show details
