The Best eSIM Referral Program Just Landed

You've already figured out the smarter way to travel. You're not paying your carrier's eye-watering roaming fees when you land in a new country. You've got a KnowRoaming eSIM sorted before you leave the house.

Now it's time to bring your people along for the ride. Meet the KnowRoaming Refer a Friend program, designed for travelers who like their rewards simple, their setup fast, and their friends to stop complaining about data bills on group trips.

How the KnowRoaming Referral Program Works

No complicated tiers, no waiting periods, no fine print to squint at. The program is built around one idea: you share KnowRoaming, you both earn.

1. Grab your referral code. Find your unique code inside the KnowRoaming app or at KnowRoaming.com/kreds. It takes about 10 seconds.

2. Send it to a friend. Drop it in a message, a group chat, or anywhere you share travel tips. There's no limit on how many people you refer.

3. Your friend signs up with your code. They create their KnowRoaming account and use your referral code during sign-up.

4. You each make a qualifying purchase. To unlock your $4 in Kreds, both you and your friend each need to have completed at least one real-cash purchase of $0.50 or more. You can do your qualifying purchase before or after you send the referral, so if you've already bought a plan, you're already set.

5. You both earn $4 in Kreds. Once both qualifying purchases are complete, $4 in Kreds lands in each of your accounts, ready to use on your next trip.

Full details are available in the KnowRoaming Terms and Conditions.

What Are KnowRoaming Kreds?

Kreds are KnowRoaming's in-app currency, and they're one of the best reasons to keep coming back. Every time you top up, refer a friend, or take part in a promotion, you earn Kreds. Those Kreds go straight back into your next data plan.

Think of it as a cashback reward system. Not a points scheme that takes three years to amount to anything useful. Real cashback, in your account, ready to spend on your next trip.

Here's what you can do with Kreds:

• Use them to pay for, or discount, any KnowRoaming data plan or top-up across 200+ destinations
• Stack them up over multiple trips and top-ups
• Earn them through the referral program, promotions, and every purchase

Kreds don't replace your data plan, they make it cheaper. Whether you're grabbing a 1 GB plan for a long weekend in Amsterdam or loading up a larger package for a month in Southeast Asia, Kreds take the edge off the cost every time.

You can see your Kreds balance and learn more at KnowRoaming.com/kreds.

Why This Referral Program Is Worth Sharing

We know you've seen referral programs that promise a lot and deliver a coupon that expires in 48 hours. This isn't that.

Here's how it stacks up: both you and your friend earn $4 in Kreds each. The qualifying threshold is just $0.50 per person. If you've already bought a KnowRoaming plan, you're already eligible on your end. Your friend just needs to make one purchase of $0.50 or more, and you're both in.

Think about it this way: the next time your travel group is sorting out data plans, send your code. Your friend's first $4 is nearly covered before the conversation's even finished.

No Roaming Shock for Them, Either

Here's the thing about recommending KnowRoaming to a friend. You're not just getting them a discount. You're saving them from a genuinely bad experience.

Anyone who's come home to a $200 roaming bill knows how quickly a great trip can get a terrible postscript. With a KnowRoaming eSIM, your friend lands connected, navigating Tokyo Station, finding their Airbnb in Rome, or catching match scores in Dublin, without their home carrier charging for the privilege.

KnowRoaming covers 200+ destinations with plans starting at a fraction of what your carrier charges. You can browse all available eSIM plans at KnowRoaming.com/eSIMs, including a Global eSIM covering 130+ countries and a dedicated Europe eSIM if that's where you're headed.

How to Install Your KnowRoaming eSIM

One of the best things about recommending KnowRoaming is knowing your friend won't get stuck on setup. Installation is straightforward on any device and done in minutes before you even leave home.

A few things to know before you start: you need a stable internet connection to install, you should install your eSIM before you depart and activate it once you arrive, and KnowRoaming offers three installation options: automatic via the app, QR code, or manual entry.

Finding Your Referral Code

Your referral code lives in two places: inside the KnowRoaming app under Refer a Friend, or at KnowRoaming.com/kreds once you're logged into your account. Your unique code is there, ready to copy and share.

There's no cap on referrals. Every person who signs up using your code and completes a qualifying purchase of $0.50 or more earns you $4 in Kreds, as long as you've also made a qualifying purchase yourself. If you've already bought a plan, you're already there.

The Short Version

You found a better way to handle data abroad. Your friends probably haven't yet.

Send them your referral code. They sign up, you both make a qualifying purchase of $0.50 or more, and you each earn $4 in Kreds. No hoops, no waiting periods, no minimum spend beyond that.

The next group trip is going to be a lot less stressful. For everyone.

Log in to your KnowRoaming account, head to KnowRoaming.com/kreds to grab your code, and start sharing. See the full terms and conditions for complete details.
