You're flying into Lisbon for a long weekend, or heading to the Algarve for two weeks of sun. Maybe you're a digital nomad setting up in Porto for a month. Either way, you need data the moment you land, not after you find a Wi-Fi password and queue at a shop.
If you're coming from the UK, your home network will happily charge you per day for roaming. If you're India-origin and keeping an Indian SIM for bank OTPs, you need a separate data line anyway. A Portugal eSIM solves both: one QR code, data on arrival, no physical SIM swap.
Match your data to your habits, not your trip length.
| Trip | Usage | Plan |
|---|---|---|
| 3 days, city break | Maps, WhatsApp, no video | 5GB |
| 7 days, mixed travel | Maps, WhatsApp video, some streaming | 5GB |
| 14 days, remote work | All of the above plus hotspot | 10GB |
| 30 days, nomad | Heavy use, daily video calls | 20GB+ |
Maps eat about 5MB per 10 minutes of navigation. WhatsApp video calls use roughly 25MB per minute. Streaming Netflix in HD is 3GB per hour. If you're unsure, go one size up, unused data is better than topping up mid-trip.
Lisbon Airport (LIS) has free Wi-Fi, but it's slow and asks for an email. Install your eSIM before you fly; data starts on first connection. You'll be on a Portuguese network within seconds of landing, no passport or payment needed at a kiosk.
Hotspot works fine. Portuguese networks don't block tethering. If you're a digital nomad, your Portugal eSIM can power your laptop. And if you're India-origin, keep your Indian SIM active for OTPs, your eSIM handles data, your Indian SIM handles verification codes.
You'll get a QR code by email within a minute of purchase. Install it on Wi-Fi before you leave, airport Wi-Fi is fine, but home broadband is faster. Data starts when you connect in Portugal, not before. Full instructions are in our install guide.
Most Portugal eSIM guides are generic tourist copy: "Lisbon's hills, Porto's wine, beautiful beaches." Ours is written for you, the UK resident tired of roaming fees, or the India-origin traveller juggling two SIMs. We also connect the dots: if you're keeping an Indian SIM alive for OTPs, recharge it from abroad while you're at it. One account, both problems solved.
| Plan | Price | Validity |
|---|---|---|
| 5GB | from $2.59 | 30 days |
| 10GB | from $2.59 | 30 days |
| 20GB | from $2.59 | 30 days |

If your phone is unlocked and supports eSIM (iPhone XS or newer, most recent Android flagships), yes. Check our compatibility guide before buying. The eSIM installs as a QR code and activates when you connect to a Portuguese network.
For a 7-day trip with maps, WhatsApp, and occasional social media, 5GB is comfortable. If you plan to stream video or work remotely, go for 10GB. You can always top up, but buying a bigger plan upfront is cheaper.
Yes. Your UK SIM stays active for calls and texts while the eSIM handles data. Watch out for roaming charges on your UK plan, check with your provider before you leave. For India-origin travellers, keep your Indian SIM for OTPs.

For most trips a 5GB to 10GB data eSIM valid for 30 days is the right size: Slashtel's 5GB plan for Portugal is $5.69 on NOS, Vodafone and MEO. Install it before you fly, keep your home SIM on for calls and bank texts, and top up the same eSIM if you run low.
If your phone supports eSIM, an eSIM is simpler than a local SIM card: nothing to collect at the airport, no passport registration, and your home SIM stays in the phone for calls and OTP texts. A physical SIM only makes sense for long stays where you need a local phone number.
From $2.59 for 1GB valid 7 days, as of 9 October 2026. Longer trips: two weeks from $3.79 (3GB), one month from $3.89 (3GB).
