KnowRoaming Promo Codes for October 2026

Worked fine in Mexico

Went to Mexico last month and decided to try an eSIM instead of my usual provider's roaming. Got the Mexico eSIM from KnowRoaming. It worked, mostly. Had data for maps and social media, which was the main thing. Installation was pretty straightforward from their app. Didn't have any major issues, just a couple of spots where the signal was a bit weak, but that happens with my regular phone too. Overall, it was a pretty smooth experience for a casual trip.

Good value for Europe trip

I was planning a trip to Europe and needed an eSIM. Found KnowRoaming and they had a Europe eSIM plan that fit my budget. I used a first purchase discount, which made it even better. The price felt really fair for the amount of data I got. It was worth it, especially avoiding those crazy roaming charges.

Excellent service, so easy!

Just got back from my trip to Japan and the Japan eSIM from KnowRoaming was fantastic! It was so easy to set up, literally took me minutes. I had internet everywhere, all the time. No more scrambling for Wi-Fi or huge phone bills when I got home. I'm definitely using them again for my next adventure. I've already told my friend about it!

Decent coverage, minor hiccup

I bought the USA Travel Data Plan for a recent cross-country drive. The coverage was generally good, and it was nice not worrying about finding Wi-Fi. Activation through their app was simple enough. My only small issue was when I tried to top up my data mid-trip; it took a little longer to process than I expected, about 10 minutes, which was slightly inconvenient when I needed directions in a hurry. But once it kicked in, everything was fine. It's a solid alternative to traditional roaming, offering good value, but they could improve the top-up speed a bit.
