ZenSim

Used this for 1 month while travelling in the UK. Worked well and I got to keep my original phone number which is really important. Price for the product was great. No dropouts, reliable coverage and speed. Show details

We had two ZimSims for our 4 weeks travelling in Switzerland. Both worked perfectly. Easy to install & activate. We will be purchasing new ZenSims for our next overseas holiday for sure. And yes the price is very competitive.

Using Zen Sim was so easy. The process from activating to using it was great. I had no issues regarding coverage and everything downloaded quickly. Will be using it for my next trip. Show details

I have recently used 2 different ZenSim- one in Europe and one in Bali. They gave excellent coverage and were very reasonably priced. As well, I had a small hitch when changing countries in Europe. I contacted ZenSim and had a reply almost immediately. Problem solved! I highly recommend ZenSim and I will definitely be using them again.

Easy process to use, hassle fee purchase system and it works well while we are travelling through Europe. Show details

Just returned from a European holiday. I never used an electronic sim before. ZenSIm was totally amazing. Easy to instal and worked perfectly. … Read more

When I did have question I sen it through WhatsApp and they responded with in minutes. Also if you buy for a region which is what I did as I was travelling through several countries it is so convenient.

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.

Very smooth process and easy to follow instructions. I had coverage as soon as I landed. Very happy with the prices and options for my last trip. I will certainly use ZenSim again

So easy to use, no issues with connection at all. Worked from the moment we landed. Easy to see how much you've used, and ability to top up quickly if needed. Will definitely use again.

Used ZenSim for the first time in August for a trip to Bali. Couldn’t have been easier to setup, and their customer service was on point. Rates are better than others available too. Will be keeping and using for all travel.

ABSOLUTELY USELESS eSim and a real waste of money. My family of four all used ZenSim on a recent trip to Bali. Never again! It didn't work for any of us 90% of the time, which meant we were mostly only online when in our hotel - a massive … Read more

inconvenience. Even my two tech-savvy teenage sons couldn't get ZenSim working.

[Name Removed] did answer my complaints promptly and tried to help, but the process was too complex, particularly since we had to be online and also, we were on holiday not wanting to wrestle with a clumsy eSim. [Name Removed] then refunded us each 20% of the fee ($6) which couldn't have been a bigger insult given how disappointing and frustrating the product was. We should've been fully refunded. Stay away from ZenSim!!!

I was expecting great things however from the start - I found it difficult to upload the esim; I took ages to work out how to activate it (new upgraded iPhone); it only worked sometimes while I was in Italy and Spain - poor reception; I had to rely on my sister’s Italian phone; any maps were useless; even when I was on wifi I didn’t get any… Read more

notification of calls received and messages and had to wait until I was back home to get 4.5 weeks of messages.The positive was that I could still message my partner on messages but had to use messenger for my other contacts in Australia with that app. I would not recommend this eSIM and next time I travel I would try another means of keeping in contact with family and friends.

Made a mistake in the choice of Sim. Was in Gibraltar which was not on zen Sim list. Mistakenly presumed that Gibraltar being attached to Spain would give me access to Spanish network. Wrong. No reception in Gibraltar whatsoever. Relied on positive reviews. My error. Sim worked OK in Spain and Portugal.

I found the service to be excellent and I will certainly use ZenSim on my next overseas trip. Originally in Turkey I didn't connect automatically but the helpful Q & A pages resolved the issue.

For Vietnam in July 2026 did everything perfectly for me and the family, even in remote areas we were never without coverage and excellent speed even when switching to best provider - no drop out. Big fan

We use ZenSim when we travel to Bali for our whole family and find it really simple to use, love that it’s an all Australian company also. We are travelling again and will be using ZenSim again.

I was extremely pleased with my Zen Sim. I purchased a 30 day data plan with 20gb of data for a trip to Europe. The e Sim worked well in all the countries we travelled through. The app was handy to check usage. I wasn't sure how much data I would need. I only used about half of it, so I will have a better idea on how much to purchase next time I… Read more

travel. I had trouble setting it up and the company had 24/7 help so I was online quickly. I highly recommend this company.

Had a little problem accessing the data sim once touched down new country… but a quick chat with support fixed it up and got my data sim running in no time. Very happy with the service! Show details

We have used Zen Sim in the past two years whilst travelling throughout Germany using mainly WhatsApp to communicate with relatives in Germany as well as Australia. We have found setup and top-ups easy. The cost is very competitive, and we experienced no issues with connectivity. When we have needed to communicate with Zen Sim via WhatsApp the… Read more

response has been fast and friendly. We will continue to use Zen Sim in the future and have recommended them to friends and family.

My second year using ZenSim data plan whilst overseas. Contacted ZenSim via email re a query I had. Super quick and friendly response, despite the time difference. 5star service all the way.

I purchased a 30 days eSim for Europe in July 2026 for 40gb. Unfortunately, my phone was stolen a few days into my 3 weeks holiday and I had only used up about 5gb. Although I couldn't get back what I had remaining, I appreciate ZenSim for being understanding and providing me with 20gb to use for the rest of my trip. Thanks Andy and ZenSim.

bought a ZenSim for our travels throughout Europe and it worked really well, not that we did any calls other than on Messenger but yes, sent emails, received emails, sent messages and sent lots of pics and video back to Australia, so yes was pretty happy with the ZenSim overall. I would recommend that you buy the unlimited as i did run out of data… Read more

about a week before coming home and had to top it up which then cost me more than the unlimited at the start would have been. Overall was an easy connection when we landed in Germany and had virtually no problems with connection any of the more remote places we travelled. Cheers.
