No QR code was sent to install the eSIM… After 3 days and dealing with multiple Support advisors, I’ve given up. Only reason I chose KnowRoaming is that they are an MTN partner. Steer clear of KR if you an MTN customer! -- Moz Roamer, 2026-10-07 ### ***** "Amazing" Huge fan of KnowRoaming speed and reliability Love the look and functionality of the new app! -- Travel_X, 2026-10-05 ### *---- "Troubleshooting a problem and feedback is just poor" I have been trying for 2 days straight to resolve an issue with an eSIM that I bought. I’ve had to repeat my problem to multiple individuals and the bot and I cannot understand why I am still waiting. Every response to a follow up is ‘I’m checking’ or ‘noted’. $14 in and I have no data. -- ΜαρίαΒ1407, 2026-08-11 ### *---- "Bad eSIM" Bad eSIM i couldn’t connect to the internet i had to buy a new physical sim after purchasing 10GB on this app -- Thailand visitor, 2026-07-30 ### *---- "Worst service ever" I have used KnowRoaming regularly for my business travels and have generally found the service very useful. Unfortunately, my most recent experience in Kigali, Rwanda, was extremely disappointing. I was using the Global eSIM, but I had no mobile service at all during my trip. Despite the eSIM not working, I was still charged for the service. I also contacted customer support for assistance but received no response. As someone who travels frequently for business and has used KnowRoaming several times before, this experience was particularly frustrating. Reliable connectivity is essential when travelling for work, and being charged for a service that did not work, while receiving no support, is not acceptable. I hope KnowRoaming will investigate this issue and improve both the reliability of the Global eSIM and the responsiveness of its customer support. -- Agrifeedsystems, 2026-07-20 ### ***** "Review - Far East eSims" Used KnowRoaming eSims in several Far East countries recently. All were efficiently loaded and worked seemlessly! Excellent alternative! -- Paul Karpeles, 2026-04-11 ### *---- "Absolute rubbish" Had a promo link from my insurance company that didn’t work. Then also installed the app to buy a USA sim. App dysfunctional and could find country. Not prepared to reinstall app. -- Suedafrika, 2026-01-26 ### ***** "Exceptional" I’m a frequent traveller and know roaming always has me covered -- Palesa798, 2026-01-14 ### ***** "Amazing" One of the best e sims on the market - highly recommend them to any travelers! -- Tjuneee, 2025-12-26 ### ***** "Top notch Assistant" I was frustrated concerning my eSIM and Lady Londiwe helped me and I was very much satisfied in her assisting me; friendly, calm and patient… -- E.G-SA, 2025-10-17 ### *---- "Scam. Do not buy." This is the worst eSim I have ever bought in my life. The staff are also dishonest when approached to explain why and how data is getting depleted. Highly recommend you do not use this nonsensical service. -- Sihle143, 2025-08-16 ### *---- "Really inappropriate marketing emails" Received an email from KnowRoaming saying “your bill is $12,755.99”. Turns out it’s a “fake bill” sent as a marketing campaign. Really inappropriate seeing as I had just been the victim of fraud on my bank account. Sent me into a panic. Fire your marketing team. -- SonOfJack@CJ, 2025-07-10 ### *---- "Help desk is not interested" When problem are reported to the help desk you are expected to allow 48 hours for it to be rectified. What a joke, so you must be stranded in another country while they call desk top support. What a joke! -- Calin123234, 2025-05-14 ### ***** "Greg Carswell" I have recently returned from a trip to Europe and KnowRoaming worked seamlessly. Even in the remote mountains whilst skiing, or in remote areas traveling by train country to country, I had uninterrupted service….KnowRoaming is a brilliant product/service I can highly recommend! -- why this option?, 2025-03-20 ### ***** "KR ESIM" I bought a KR eSIM for SA and it was an absolute bliss to use. Super easy to buy and required little to no effort to install. Great overall experience -- 5atare, 2025-02-26 ### ***** "Works every time!" Once I moved to KnowRoaming I have never looked back. I have used it in Europe and Asia and it always works seamlessly and keeps me connected. The app is great and easy to use. -- Chole1000, 2025-02-24 ### ***** "European eSIM" I bought a 50GB European eSIM. It worked perfectly. I travelled Europe for a month going from Germany to Portugal to Switzerland. I never once had a problem. It was amazing! Totally worth the purchase. Would highly recommend everyone to purchase one when travelling. -- Kirrie_woods, 2025-01-19 ### ***** "Effortless" This app worked instantly upon my arrival in the foreign country. Easily topped up, and switching between primary and secondary sims were effortless. -- livelifetwice, 2024-10-01 [View all KnowRoaming Travel eSIMs reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## KnowRoaming Travel eSIMs Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Free | South Africa | Travel | #86 | ## KnowRoaming Travel eSIMs Available In -
