How to top up your Kolet eSIM
Learn how to top up your Kolet eSIM, compare costs, and explore alternatives like Holafly for unlimited data and easy travel connectivity.
Kolet is a global eSIM provider offering eSIM plans in over 190 countries. Their data-only eSIMs provide internet access, but if you run out of data, you’ll need to top-up your plan to stay connected.
In this article, we’ll explain how Kolet eSIM top-up works and whether topping up an existing plan is more cost-effective than buying a new one. If you prefer unlimited data without worrying about usage, you might consider Holafly, an international eSIM provider with plans for over 200 destinations.

Can you top up a Kolet eSIM?
Yes, you can. Kolet offers a top-up service that lets you add more data to your existing eSIM plan. This top-up feature allows you to stay connected without having to purchase and activate a brand-new eSIM.
If you have more than 1GB of unused data remaining on a paid plan after your trip, Kolet can also convert it into a voucher for your next journey.
How to top up a Kolet eSIM: Step-by-step
Kolet eSIM top-up is straightforward via the Kolet app. Here’s the step-by-step instruction:
- Open the Kolet app
- On the home screen, tap + Add More Data
- Select your destination
- Choose the data allowance you need
- Enter payment information and confirm your purchase
Once the payment is completed, your eSIM will be ready to use with the added data. If you prefer not to top up your current eSIM, you can also buy a new Kolet eSIM directly from their website.
Pro Tip: If you top up before your existing country-specific or regional plan expires, any unused data and remaining validity will roll over for an additional 30 days.
Kolet eSIM top-up costs
Kolet’s top-up prices are the same as purchasing a new plan. The exact cost depends on your destination, data amount, and plan duration.
Here’s an example of Kolet’s Asia regional plan prices:
- $5.99 for 1GB
- $14.99 for 3GB
- $21.99 for 5GB
- $36.49 for 10GB
- $54.99 for 20GB
Most of the regional prices are somewhat similar to the Asia regional price above, though some of the other destinations might cost more.
Is an unlimited data eSIM better than buying top-ups?
It depends on your needs — factors like data amount, trip duration, and travel budget will influence your decision.
Topping up will keep your existing Kolet eSIM active without reinstalling, and unused data can roll over if you top up before the plan expires. However, frequent top-ups can raise the total cost and require careful timing to avoid losing unused data.
Unlimited data eSIMs like Holafly remove the need to track usage and allow you to travel without worrying about data limits. The trade-off is a higher upfront cost, which may not be suitable for budget travelers.
To help you decide, here’s a cost comparison table based on a 10-day trip to Europe.
| Kolet Europe regional eSIM | Holafly Europe eSIM |
|---|---|
| 1GB for $3.99 | Unlimited data for $36.90 |
| 5GB for $18.49 | |
| 10GB for $25.49 | |
| 20GB for $38.49 |
As you can see, you can get unlimited data from Holafly for less than 20 GB from Kolet. On top of that, buying 5 GB and topping up with another 5 GB would cost the same as unlimited data from Holafly.
On top of unlimited data, Holafly also offers flexible durations from 1 to 90 days, which allows you to manage your travel budget more easily and avoid paying for any days you don’t need.
To conclude, Kolet eSIM top-up is suitable for light data use, while Holafly’s unlimited eSIM is a strong Kolet alternative for heavy data users who prefer not to monitor usage.
