How it works

Three steps to working data abroad

Under five minutes end to end — most of it choosing the plan. No airport kiosk, no surprise bill.

  1. Pick a plan

    Choose your destination and data tier — 1 GB starters through Unlimited. Not sure how much you need? Roger recommends in three questions.

  2. Pay in ~30 seconds

    Apple Pay, Google Pay or card — secured by Stripe, we never see your card details. Your QR code lands in your inbox seconds after payment.

  3. Scan & forget

    Install before you fly — validity only starts when you first connect abroad. Your phone switches on arrival; your home SIM keeps its number.

⭐⭐⭐⭐⭐ Price / Service / Fast

My experience with eSIM Genius was excellent. The installation was quick and very easy, and the connection activated automatically every time I entered a new country. I traveled through 4 countries in just one week, and everything worked perfectly without any issues.

Brilliant esim

Paid for unlimited for a week for my teenage daughters, the online chat team were great at answering any questions. The girls were able to use their phones all around Turkey without any problems. Anyone with teenagers needs esims when travelling. Super cheap too.

I've had so many nightmares with other popular sim companies. This one worked straight away. Just what you want and expect.

The setup was very easy

The setup was very easy, and the connection speed was excellent. Some people may hesitate to choose it because it's not very well-known, but it's genuinely a great service. I didn't experience any problems at all. The prices are also really affordable. I highly recommend it!

Beats roaming. Beats airport kiosks.

Four reasons travelers switch once and don’t go back.

Cheaper than roaming

Carrier roaming runs €10–15 per day. A typical 7-day trip here costs under €10 total — no surprise overage for streaming a few extra videos.

Faster than a physical SIM

No airport queue, no 30-minute kiosk wait, no tiny plastic tray to lose. Scan a QR and you’re online before your luggage hits the carousel.

Keep your home number

The eSIM runs alongside your normal SIM — your number still gets calls, bank codes and WhatsApp while the travel eSIM handles data.

Starts on first connection

Validity begins the first time the eSIM connects in a country your plan covers, not at purchase. Buy days ahead, install at home, and keep the line switched off until you travel.

WHY TRAVELERS STAY

Buy once, benefit every trip

Three things most eSIM sellers don’t do.

Up to 10% back in Genius Cash

Every order earns cashback you can spend at checkout — it can cover a whole order. Your rate grows with lifetime spend:

Refer a friend — both win

They get 10% off their first order. You get 15% of it back in Genius Cash — up to $15 per friend.

Unlocks 14 days after their eSIM is delivered.
One eSIM. Every trip. Forever.

Your eSIM never expires. Keep it installed and just top up when you travel again — no new QR, no reinstalling. Land, switch on, done.

Questions travelers actually ask

Will my phone work?
When does my plan’s validity start?

On first connection to a network in a country your plan covers, not at purchase. Buy and install days ahead; the clock only starts when the eSIM line first connects, so keep it switched off until you travel.

Do I keep WhatsApp and my home number?

Yes. The travel eSIM handles data while your home SIM stays installed for calls and texts — WhatsApp keeps working with your existing number.

What happens if the eSIM doesn’t activate?

Full refund. Email support@esimgenius.ai with your order ID and we’ll sort it within one business day.

Do plans include calls and SMS?

Plans are data-only. Calls work over WhatsApp, FaceTime, and any internet-calling app — which is how most travelers call home anyway.

Is paying online here safe?

Payments run through Stripe — card details are entered in Stripe’s own secure frame and never touch our servers. Apple Pay and Google Pay are supported.
