Why KnowRoaming?
We’ve been testing KnowRoaming across six countries over the past months. Here’s what we’ve found:
The speeds are good
Connection quality has been pretty solid everywhere we’ve tried it. Europe and the US have been particularly good and we actually hit 473 Mbps in Portugal, which was faster than our home WiFi (slightly embarrassing, but there you go).
Here’s how that breaks down in every country we’ve tested so far and how they compare with the competition.

Good coverage
KnowRoaming covers over 200 countries, which means you’ll have service in most places you’re likely to travel. We’ve found their coverage reliable in the destinations we’ve tested.
Two types of plans that make sense
They keep it simple:
- Fixed data: 1GB to 100GB, lasting 7-30 days
- Unlimited: No data limits for 1-30 days
Their unlimited plans are where they seem to shine. We’ve noticed they offer more unlimited options than a lot of other providers and the pricing tends to be competitive.
Amazing value on unlimited global plans
KnowRoaming is currently offering their Unlimited Global plans at 80% off. If you’re hopping between countries and don’t want to worry about running out of data, this could be a game changer.
Single eSIM installation
One thing KnowRoaming does really well is their single eSIM installation feature. Once you’ve installed their eSIM on your phone, you’re pretty much set and you don’t need to go through the process again every time you travel somewhere new. However, bear in mind that the single eSIM only works with their regional and global plans.
The app works great
No complaints here. It’s clean, loads quickly and doesn’t confuse you when you’re trying to buy data at 2am in a foreign airport.
Live chat actually works
They have live chat on their website and WhatsApp. We’ve used it a couple times and got helpful responses from actual humans, which is great.

Our take
KnowRoaming has worked well for us. The service is reliable, the unlimited plans offer good value and that single eSIM setup saves time when you’re bouncing between countries. The 20% off with our KnowRoaming promo code KR20XP makes it worth considering if you need travel data.
KnowRoaming Frequently Asked Questions (FAQs)
1. What is KnowRoaming?
It’s an eSIM service for travelers. They offer data plans for 200+ countries with both fixed data amounts and unlimited options.
2. Is KnowRoaming reliable?
Based on our testing in six countries, yeah, it’s been solid. Good speeds, consistent connections, especially in Europe and the US. Their unlimited plans seem to offer the best value.
3. Does KnowRoaming work?
In our experience across six countries, yes, it works well. It’s been consistent enough for everyday use everywhere we’ve tested, except for Hong Kong where we had some connectivity issues. We think that was a problem with the local network though because we had the same issue with other providers there. Worth noting anyway.
