Good customer service

It would be helpful if somewhere there were instructions on seeing if the phone’s sim is unlocked and able to use this. Before standing in the airport in Iceland.

Developer Response
Thanks so much for the honest feedback, and we're really glad our support team looked after you in Iceland. To clear this up: our app checks whether your device is eSIM compatible, but carrier lock is a separate thing set by your home provider, so it isn't something we can check from our side. A quick call to them before you fly is the easiest way to confirm. We're sorry this caught you out at the airport, that's not the start to a trip we want for anyone. We'll make this clearer going forward so travelers can check both before they leave home. Wishing you smooth travels ahead, get your phone unlocked early and you'll be connected the moment you land.

Support worse than useless

This app worked seamlessly last yr for my 1wk in Canada, so I thought to use it again this summer (‘26)….however, they were unable to correctly walk me thru how to properly configure my phone, and even upgraded my issue to a higher-level support “team”, but 2 different persons were unable to get it working, and this entire enterprise wasted over 3hrs —much of it on multiple long holds. The next day, I went to a FreedomMobile kiosk in a mall (BC), and sales guy there got my phone working easily (w FreedomMobile eSIM I was happy to purchase) in less than 10min. To make matters worse, KnowRoaming proceeded to ignore my request for a refund for the eSIM I had purchased and not been able to use—this is unacceptably poor customer support. They never replied to two different emails I send them over the next week….then I dropped it. They lost a customer forever. Clearly they don’t care.

Useless for physical SIM

Since announcement of sunset of physical SIM cards Knowroaming app cannot let you access your account and you cannot access online through a browser. Considering they are going to delete all existing credit after sept 1st unless you reload it will expire again in 9 months after the last reload date available on sept 9th. Which you cannot access your account to reload anyway. They also won’t move any credits over to an eSIM. This is a big scam.

Developer Response
Very sorry to hear about your experience. We are focusing all of our efforts on our eSIMs, to make it the the best eSIM platform available. Hence why we are ending our SIM platform. Please contact our 24/7 support team for assistance, via our website.

Too slow after the first 5GB

DM-1991
Tried the twice and it was good and fast. The third time was too bad. I bought unlimited internet only to realize when you finish 5GB in a day you the internet drops drastically. It drops to a point where you can finish a full cigarette while waiting for a short video to load and maybe more. ( just to so you can visualize what I mean by slow😅). They said for each 24hrs you get 5GB PF high speed internet. Unfortunately that didn’t happen. After that first 5GB it wasn’t like the first time I used it.

Developer Response
Thanks so much for the detailed feedback, it really helps us know exactly where this fell short for you. Our unlimited plans include 5 GB of high-speed data per day, more generous than most providers, who typically cap it at just 1-2 GB. After that, speeds do drop so everyone sharing the network stays connected, and we're sorry that wasn't clear before you bought. We're working on explaining this better upfront so no one gets caught out mid-trip like you were. If your speeds stayed slow beyond that first day rather than resetting, that's not how it's supposed to work, please reach out to our 24/7 support any time and we'll sort it out for you.

A whole new KnowRoaming: Install once, add plans forever. We've moved to a universal eSIM. Instead of a new eSIM for every destination, you now have one eSIM that works wherever you travel. Install it once, and it stays on your phone for every trip after that. Heading somewhere new? Just add a plan for that destination in the app and you're ready to go. No reinstalling, no scanning new QR codes, no setup every time you travel. We've also given the app a fresh new look. It's cleaner and easier to use, so finding the right plan and managing your data takes just a few taps. Everything runs faster and smoother, from browsing destinations to getting connected when you land.
