Kolet eSIM Review: The details
Here’s a closer look at what Kolet brings to the table. Let’s peel back the layers and review their coverage and pricing, as well as the Kolet app features and customer support options.
Network coverage
Kolet eSIM helps travelers stay connected in 190 countries, including major travel destinations such as the USA, Europe, Australia, and regions in Asia and South America. They work with local carriers to provide 5G where available, though some destinations may still rely on 4G networks, which can affect speed and quality.
In some destinations, Kolet eSIM will connect to only one local network, while in places such as the UK or the USA, you can choose among several networks. You can check that information as you purchase your Kolet plans.
Plans and pricing
The prices for Kolet’s data plans depend on the destinations. That’s why, for some places, the cheapest option for a data plan is $3.99, while these starting prices can go up to $12.99. Here are the prices for some of the destinations. The validity period for all data plans is 30 days.
| Destination | 1GB | 3GB | 5GB | 10GB | 20GB |
|---|---|---|---|---|---|
| USA | $4.49 | $8.99 | $14.99 | $22.99 | $34.49 |
| UK | $4.49 | $8.99 | $13.49 | $20.49 | $33.49 |
| South Africa | $4.49 | $12.49 | $17.99 | $30.99 | $51.49 |
Key features
Kolet’s eSIM service is similar to what most eSIM providers offer. This means you need an eSIM-compatible phone to use this service. Your new eSIM will be data-only, and you will primarily manage it through the Kolet app. Additionally, some features specific to Kolet make it a good option for travelers looking to stay connected.
- Single eSIM for all destinations: Keep the same eSIM across 190 countries — just top up data when you arrive in a new destination. No need to remove your physical SIM or swap eSIMs.
- Pre-travel installation: Set up your eSIM before departure and activate it upon arrival.
- Travel partners gift: Enjoy a complimentary 1GB of data when you book your international travel through one of the Kolet travel partners.
- Referral program: Share Kolet with friends and earn a $3 discount for each referral, with easy steps in the Kolet app.
- Supports hotspot functionality: Share your Kolet connection with other devices.
- Gift eligibility: Each traveler gets one 1GB gift per international trip, transferable to a companion. If you decide to add more, you will need to add a payment method and purchase more data through the Kolet app.
Kolet app
Kolet’s app allows you to browse available plans, make purchases, and activate eSIMs directly. Additional features in the app include easy top-ups, a Help Center for support, and options to manage personal settings, such as redeeming referral codes or viewing purchase history. The app is compatible with most eSIM-ready Android and iOS devices, though some features may be limited by device compatibility.
Purchase and activation
To purchase a Kolet eSIM, users can choose between the Kolet website or the mobile app. Activation is straightforward and involves selecting an installation method: QR code, activation code, or automatic setup. Each method includes step-by-step instructions, ensuring easy setup regardless of tech experience. Keep in mind that you’ll need an internet connection to install your eSIM.
Here’s what you need to do:
- Open the Kolet app or website: In the app, go to the Home section and tap “Install my eSIM now.” On the website, purchase your eSIM and data plan if you haven’t already.
- Choose an installation method:
- Automatic installation (recommended): follow the on-screen instructions in the Kolet app.
- Activation code (manual input): manually enter the code provided in the app, ideal if the automatic setup isn’t accessible.
- QR code (scan with another device): scan a QR code with your device.
- Follow the instructions: Complete the on-screen steps for your chosen method.
- Activate at destination: Open the Kolet app and activate your data plan. You don’t need the internet to activate your plan.
Customer support
Kolet provides two main support options: a Help Center with answers to frequently asked questions and a live chat feature initially managed by a bot. Users can escalate issues to speak with a representative, and they respond to their chat within minutes. Kolet offers support in English and French, though additional language options may be limited depending on the region.
Kolet eSIM review: The conclusion
Kolet eSIM is a new but promising option for frequent travellers and first adopters willing to give new companies a chance. With a single reusable eSIM, Kolet offers data plans for 190+ destinations. However, when you compare eSIMs from Holafly vs Kolet, Holafly offers unlimited data travel plans, so you won’t have to worry about top-ups or running out of data.
