Easy to use, just frustrating that I couldn't make phone calls but worked well all the time.

Tried KnowRoaming for the first time in…

Tried KnowRoaming for the first time in Europe due to some advice about certain countries being difficult. eSIM would not work despite trying all the trouble shooting options. Tried everything including restarts. Nothing. Went to another company I used in the past and worked immediately without issue. Tried contacting via website and no response. Not worth it. Go elsewhere

Thank you for taking the time to share such detailed feedback, we’re really sorry to hear this was frustrating. That’s not the experience we aim to deliver. Promotional eSIMs provided via travel insurance do have specific redemption steps, and we understand how broken links or unclear guidance can make the process confusing. We appreciate you flagging this and will share it with our team so we can improve the flow and instructions.

Our support page does include detailed installation guides and troubleshooting steps, including APN changes when needed, but we understand this wasn’t easy to find at the time. We’re glad you managed to get the eSIMs working, and we agree the process should be smoother and more intuitive. Our 24/7 support team is always available to help resolve setup issues quickly and link plans correctly. Thank you again for your patience and feedback.

The Top-Up process of a Data eSim for…

The Top-Up process of a Data eSim for Turkey that I bought, was attrocious. I was caught with no data in Istanbul. I could not order Uber and I missed 2 paid-for tours. It was an extremely bad experience.

We’re really sorry to hear about this, that must have been incredibly stressful, especially while navigating a busy city like Istanbul. That’s not the experience we want for our travelers.

In some cases, after a top-up, the phone may need a quick refresh for the new data to register. Turning Airplane Mode on for a few minutes and then off again, or restarting the phone, usually resolves this straight away.

For future trips, we also recommend enabling Auto Top-Up in the app, which automatically adds data before you run out and helps avoid unexpected interruptions. Our 24/7 support team is always available to assist in real time if anything goes wrong. Thank you for sharing this, your feedback helps us improve.

Used on multiple trips

I’ve used KnowRoaming eSIMs on multiple trips this year and the experience has been without issue so far. The setup takes less than two minutes, the instructions are clear, and the connection activates immediately once you land (like the UK, Europe etc.)

Coverage has been strong in every country I’ve used it in so far, and data speeds were fast enough for maps, social media, uploading content, and hotspotting when needed. I also really like that the app shows your usage in real time, so you never have to guess how much data you have left.

Pricing is very fair compared to other eSIM providers, highly recommend.

Hi Junaid, thank you for sharing your experience and I am really sorry to hear that your trip to Zambia did not go as expected. This is never the kind of experience we want for our travelers.

Sometimes local network providers in certain regions experience issues that can affect connectivity. A quick message to our 24/7 support team usually allows us to switch you to a different network or update your settings so you can get online as soon as possible.

Please reach out to us with your order details so we can take a closer look and make this right for you. We want every trip to feel simple and stress free and KnowRoaming is committed to giving you the best eSIM experience wherever you go.

It didn’t work in Myanmar

It didn’t work in Myanmar. I had „KnowRoaming Asia“ including Myanmar, China, Laos, Thailand, Australia, etc. In the other countries it worked fine.

Hi Peter, thanks for your feedback. We are sorry to hear that you were not able to connect in Myanmar. Sometimes local network providers experience issues that are unfortunately out of our control, but a quick message to our support team during your trip can often help. They can guide you through changing settings, switching to another available network, or let you know if there is a local outage affecting connectivity. If you travel with KnowRoaming in the future, please reach out so we can help you get set up smoothly.

Best e-Sim company out there!

I’ve been using KnowRoaming since the sticker sim days. Easy to connect my e-sim with easy instructions. My e-sim immediately connected to the network in Sri Lanka (where I travelled to this time). No issues with connection to the network throughout my trip. Great service & great product. Would recommend & is recommending KnowRoaming to everyone.

Great experience

Apart from using an esim the first time, the overall experience was great. It worked flawlessly and helped me negotiate travel/transit uncertainty.
