What is SimFuse?
SimFuse is an online store for travel eSIMs. An eSIM is a SIM profile you download to your phone instead of inserting a plastic card. SimFuse plans are prepaid and run on established local carriers in each country, so you avoid roaming fees and keep your number. Most plans are data only; some include calls and SMS.
How does SimFuse work?
Three steps, and the first two happen before you leave home.
Pick a plan
Choose a country or a region, an allowance and a number of days. The price on the plan is what you pay, in your currency.
Install over Wi-Fi
Scan the QR code from the email, or install from the SimFuse app. It takes about 2 minutes.
Connect when you land
The plan's days start on first connection, not at purchase. Switch mobile data to the eSIM and you are online on arrival.
Built for the moments a trip needs data
At the gate
Install before you board. The plan's days start when you land, not before.
On the first street
Maps, rides and messages work from the moment you arrive, without hunting for Wi-Fi.
A few days in
Top up in the app when you need more data, or add the optional VPN for hotel Wi-Fi.
What makes SimFuse different?
Each point below is something you can check before you pay.
One price, shown upfront
The price on the plan is what you pay, shown in your currency and paid by card, Apple Pay, Google Pay or crypto. No subscription and no roaming bill when you get home.
A refund if you never use it
Wrong plan, or a phone that turns out to be locked? An eSIM that never connected to a network is refunded in full within 30 days of purchase.
Delivered in seconds
The QR code arrives by email moments after payment, so you can install it over Wi-Fi at home and land already connected.
Networks named, not hidden
Every country page names the local carriers your plan uses and, where the carrier reports it, whether that network is 5G or 4G/LTE.
Keep your number
The eSIM sits next to your home SIM. Your number stays on your phone, and WhatsApp keeps the number you registered.
In 18 languages
The site, checkout and install guides are translated, and prices show in your local currency.
Where can you use SimFuse?
In 207 destinations. Buy a plan for one country, or a regional plan that covers several countries on one eSIM.
