Portugal eSIM FAQs
Your eSIM will activate automatically once you step off the plane in Portugal. We do suggest installing your Portugal Travel eSIM before departure (installation ≠ activation).
Installation is a breeze: scan the QR code provided or install via the ZenSim app over WiFi. Upon landing, the eSIM will activate itself.

Hands down, a travel eSIM beats roaming in Portugal. Here’s why:
Cheaper Data: Pay local prices rather than roaming surcharges from your home network.
Instant Setup: No waiting for physical SIM delivery - your eSIM is ready the minute you land.
Full Expense Control: Track data usage and spending in - app, so you avoid surprise fees.
Your Portugal travel eSIM kicks in as soon as you arrive in Portugal - provided it was installed beforehand.
If you install it after you land, it should start working right away.
If you run into trouble, see our eSIM Troubleshooting Guide or get in touch with us.
Definitely. Install your Portugal travel eSIM up to 30 days before departure, and it will activate automatically when you arrive.
Installing early won’t consume data or days from your plan until you land in Portugal.
If an iPhone shows an activation error when installing abroad, you can safely ignore it - check our eSIM Troubleshooting Guide for guidance.
Connectivity Troubleshooting: Check our troubleshooting guide if your eSIM won’t connect. Still stuck? Hit up our support team and we’ll get you back online fast.
eSIM Installation Help: For help setting up your eSIM, visit our installation guide, or simply contact us - we’re happy to assist.
Other Inquiries: Have another issue? Head to our contact page and we’ll respond ASAP.
Traditional calls and SMS aren’t part of our Portugal eSIM packages - they’re strictly data provision. To talk or text, use internet - based services (WhatsApp, Signal, etc.) with your eSIM data.
No, the Portugal eSIM is data - only and excludes voice/SMS numbers. You’ll have to rely on data - based messaging platforms like WhatsApp or Telegram for calling.
Yes! Our eSIMs cover more than 200 countries, including Portugal. We even provide regional eSIMs that span multiple countries in one package - head over to our Travel eSIMs page to learn more.
Data and plan days only kick in when you arrive in Portugal. Installing earlier just prepares it for activation which happens automatically when you arrive in Portugal.
Install over WiFi before your trip to get connected from the minute you touch down.
If you have trouble connecting, see our eSIM Troubleshooting Guide or message us for assistance.
Absolutely. Nearly all of our Travel eSIMs can be extended directly inside the ZenSim app in just a few taps. You can top up extra data, more days, or even include an additional country on the same eSIM, you’ll find everything in the Zen Garden top up section.
Just sign in, head to the Zen Garden, and you’ll spot the option to top up your eSIM straight away.
Top up plan details: The Portugal options mirror the website plans, with an added 10% savings.
Longer trips: If your adventure goes beyond 30 days, you can stack as many top ups as you like. Each one activates only after the previous plan ends, so you can buy them in advance without affecting your current eSIM.
Add more countries: Many of our eSIMs now support multi country top ups. For example, if you're using a Europe eSIM and have a stopover in Dubai, simply add a Dubai top up and it will activate automatically when you land without needing a new installation.
Your Portugal eSIM is designed for use within Portugal, so once it's been activated there, it won’t work in other countries.
If you're visiting multiple destinations, a better option might be one of our regional Travel eSIMs that cover entire regions like Europe or Asia.
