What is Kolet eSIM?

Kolet is a French startup founded by four entrepreneurs that focuses on simplifying connectivity for travelers. It offers eSIM plans for 190+ destinations worldwide, with both local and regional plans available. All Kolet plans offer a fixed amount of data, with no unlimited plans available, making it a solid option for budget-conscious users who don’t use a lot of mobile data.

Kolet eSIM pros and cons

Before we dig into the details of our Kolest eSIM review, here is an overview of the good and not-so-good things about how Kolet works:

Pros:

• Affordable pricing starting at $3.99 for many destinations
• Hotspot sharing lets you connect multiple devices
• Reusable eSIM — top up for new countries without changing eSIMs

Cons:

• No unlimited data — all plans have data caps
• Very limited regional plans — EU only, no Asia or other multi-country eSIMs
• App required for activation and management
• No 24/7 support — limited to chat with FR/EN only

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 in areas where available, though some destinations may still rely on 4G networks, which impacts 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.

One of Kolet’s downsides is that it doesn’t have many regional eSIM data plans. Like the Holafly eSIM for Europe, Kolet does offer a regional plan for the EU — but it’s missing non-EU European destinations like the UK. Plus, while Holafly has best eSIM for Asia travel and other regions, Kolet doesn’t offer multi-country eSIM plans. If you plan to travel to several countries in these regions, you must buy a data plan for every new country you visit. 

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.

Key features

Kolet’s eSIM service is similar to what most eSIM providers offer. This means that you need to have an eSIM-compatible phone to use this service. Your new eSIM will be data-only, and you will mainly manage your eSIM through the Kolet app. Besides that, some features specific to Kolet make it a good option for travelers 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, transferrable 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 simplifies the eSIM process with options 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, although some features may be limited depending on 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:

1. 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.
   
2. Choose an installation method:
   1. Automatic installation (recommended): follow simple on-screen instructions in the Kolet app.
   2. Activation code (manual input): manually enter a code provided in the app, which is ideal if the automatic setup isn’t accessible.
   3. QR code (scan with another device): receive a QR code to scan with your device.
      
3. Follow the instructions: Complete the on-screen steps for your chosen method.
   
4. 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.
