Data usage guide
Short answer: more than you think, for longer than you think. Typical travelers use roughly 1 to 2 GB per day, heavy users far more, and the average connected trip to Portugal runs about three weeks. This guide breaks down what each activity consumes, lets you build your own daily estimate, and shows when the honest answer is simply to stop counting.
Trip ready checklist
Approximate per-hour figures: turn-by-turn navigation 5-10 MB, messaging and email a few MB, social feeds 100-200 MB, music streaming 50-100 MB, video calls 300-700 MB, SD video streaming around 700 MB, and HD streaming 1.5-3 GB. Photo and video cloud backup is the silent giant: a single day of holiday photos and clips can sync several GB in the background.
Light use (maps, messages, a few searches and posts): about 0.5-1 GB per day. Typical tourist use (all of that plus social feeds, music in transit, photo backup and the odd video): 1-2 GB per day. Heavy use (video calls, streaming in the evening, hotspotting a laptop, kids on tablets): 3-5 GB per day or more.
This is where capped plans quietly fail. Our order data shows the average connected trip to Portugal runs about three weeks, and most rentals run 9 days or more. A "generous" 10 GB travel eSIM spread over three weeks is less than 0.5 GB per day, and global eSIM brands whose "unlimited" plans throttle after a daily allowance hit that wall every single evening.
The moment you tether a laptop, the numbers jump. Operating system updates, cloud drives, mail attachments and video meetings consume in minutes what a phone uses in a day. If laptop work is part of the trip, plan around a pocket WiFi hotspot built for sustained multi-device use rather than draining a phone battery on tethering.
Autoplaying reels and stories, app updates over mobile data, photo backup at full resolution, and navigation rerouting on road trips all consume far more than people budget for. Practical trims: download offline maps and playlists before flying, set photo backup to WiFi-only, and turn off background app refresh for apps you do not need on the road.
Every estimate on this page becomes irrelevant with genuinely unlimited data. Portugal Internet plans run on the native Portuguese network with no daily cap, no throttling and no fair-use clause: eSIM from EUR 9, pocket WiFi for up to 10 devices from EUR 18, physical SIM from EUR 15. You stop counting megabytes and just travel.
Maps, rides, restaurant searches, social posts and photo backup: plan for 1-2 GB per person per day, more on museum-and-cafe days with heavy browsing.
Two adults navigating and posting plus kids streaming in the car and at the hotel: easily 4-8 GB per day combined. One unlimited pocket WiFi covers everyone at once.
Video calls alone can consume 0.5 GB per hour, plus cloud sync and a laptop online all day: 3-6 GB per day is normal. Throttled plans visibly degrade calls.
Navigation is cheap but constant, and evenings bring streaming and backup: 1-3 GB per day, with offline maps as the safety net in rural valleys.

Fantastic service - we spent 7 days in Porto with a pocket wifi provided by Portugal Internet. The delivery service was excellent - it was delivered to the hotel a few days before our arrival. Good internet reception and we had no issues. Returning it was very easy as well - following the instruction, we posted it at local post office.
Great service. I used the mifi unit. Worked well all across Portugal . Delivered to my postal station near where I was staying and easy to return at airport.

For light use, yes: maps, messaging, email and some browsing fit in 1 GB. Add social feeds, music streaming and automatic photo backup and most travelers land in the 1-2 GB per day range, which is why capped plans feel tight by the second week.
At typical tourist usage of 1-2 GB per day, plan for 15-30 GB over two weeks. Remember that the average connected trip in our data runs about three weeks, so if your plans might stretch, unlimited data is the safer call.
Text and voice messages are negligible, voice calls use around 30-50 MB per hour, and video calls 300 MB or more per hour. It is the video calls home that add up, not the messages.
Video in all its forms: streaming, video calls and autoplaying social feeds, followed by full-resolution photo and video cloud backup. Navigation, messaging and browsing are comparatively cheap.
4G LTE comfortably handles maps, streaming and calls. 5G adds speed in cities where available. What matters more than the G is throttling: Portugal Internet data is full-speed with no cap, so video calls do not degrade after a daily allowance.
Download offline maps and playlists before flying, set photo backup to WiFi-only, disable autoplay on social apps and turn off background app refresh. Or choose an unlimited plan and skip the housekeeping.
