An overview of ChillSim's performance across 6 criteria
How we score
This score is eSIMrat's own, not an average of customer reviews. It covers six criteria we assess ourselves from the catalogue's real coverage, the prices we record, and test purchases and installs. We earn a commission on sales made through our links: it changes neither the score nor the order of our rankings, which stay sorted by price per GB.
The eSIMrat verdict
ChillSim is the eSIM brand of Zenminutes, a Romanian company: 191 countries and 10 multi-country plans available with us, all in euros. Its strength lies in the pricing for small and medium data volumes: in France, 1 GB for 7 days for 3.00 € and 10 GB for 30 days for 12.00 €. The iOS and Android app installs the eSIM and manages top-ups, and support responds 24/7 via WhatsApp. Its limitations: the carrier is never named, and a purchased plan is only refunded in the event of a technical failure on their end.
Good for
- Short stays where you want a few GBs for cheap (1 GB for 7 days at 3.00 € in France)
- Travelers who want to pay in euros, taxes included, without conversion
- Road trips through multiple European countries, with the Europe+ plan covering 36 countries
Less suited if
- You want to know which local operator you will be using before buying (→ eTravelSim)
- You want to be able to get a refund for an unused eSIM (→ eSIMPal)
- You are looking for excellent value for money with an eSIM that is easy to install, an app that is easy to use, and 24/7 human support (→ voilà eSIM)

How to install your eSIM with ChillSim
Buy your plan
Choose your destination on the website or in the app, then select the data volume and duration. You pay in euros, including taxes, by credit card, and the QR code arrives via email right after purchase.
Pick your destination
Choose your destination and your data plan.
Scan the QR code
Install the eSIM via Wi-Fi before departure: via the ChillSim app (My eSIM, Current plans, Install) or by scanning the QR code from the email in your phone's eSIM settings.
Get connected
Once on-site, choose the ChillSim line for mobile data and enable data roaming: validity begins upon the first connection to the network. You can track your usage in the app.
If something goes wrong
Check that your phone supports eSIM (iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later) and is carrier-unlocked. Make sure you have a stable Internet connection during the install. If the problem persists, contact ChillSim support with your order number.
Turn Airplane mode on and off again. Check that the eSIM from ChillSim is selected for mobile data in your settings. Turn data roaming on. Restart the phone. If nothing changes, switch network selection to manual and pick another operator.
Look at per-app usage in your phone's settings to spot the hungry apps. Turn off automatic updates and high-resolution video playback. Your remaining data shows in your ChillSim account, or in its app when there is one.
The QR code is in the email sent after purchase, and the eSIM can also be found in the app, under the My eSIM section, using the same account. If it doesn't arrive, write to support on WhatsApp or via the contact form, including your order email.
