Business travel internet in Portugal

What needs to work

• Video calls (Zoom / Teams / Meet): use ~800 MB–1.5 GB/hr. You need at least 5 Mbps stable. Urban 4G in Portugal usually delivers that.
• Corporate VPN: works well on eSIM. Most data networks don't block standard VPN protocols. If your VPN uses a fixed IP (e.g. WireGuard), configure it before you travel.
• Email + cloud platforms: low consumption (~50–100 MB/hr of active use). No issues on 4G.
• Hotspot / tethering: if you need to connect a laptop, check your eSIM plan allows tethering (most do, but some restrict it).

Backup plan for critical meetings

Don't rely solely on mobile data for an important presentation. Find a coworking space or café with fast Wi-Fi as a backup. For long calls, use Wi-Fi with the eSIM as fallback.

How much data for a working week?

With 2–3 video calls per day + email + browsing: ~3–5 GB/day. For a full working week: minimum 15–20 GB. With tethering: 25+ GB or unlimited.

Quick checklist: stay online without surprises

The make-or-break moment is often the first 30 minutes after landing: maps, transport, messages. Install your eSIM on Wi‑Fi before you travel and switch mobile data to the eSIM when you arrive. That way you're not dependent on airport Wi‑Fi and you avoid accidental roaming charges.

For typical use (maps + messaging + light social media), 1–3 GB per week is often enough. If you tether for a laptop, take video calls, or stream daily, aim for 10 GB+ or a plan with fair-use throttling instead of a hard cut-off.

• Networks: MEO (5G), NOS (5G), Vodafone (5G)
• Offline maps: download the area in Google Maps while you're on hotel Wi‑Fi.
• On the move: Uber, Bolt, FREE NOW + WhatsApp work well on low data — video and app updates are usually the real data drains.
• Common weak spots: Alentejo and interior plains with sparse infrastructure · Douro Valley narrow roads
• City context: Lisbon: Excellent coverage; hilly alfama streets can vary indoors. · Porto: Good 4G/5G; riverside Ribeira district well-covered.

Phone setup tip: keep your primary SIM active for calls/SMS (so 2FA codes can arrive), but turn off mobile data on that line. Set the eSIM as your data line — it prevents accidental roaming on the wrong SIM and keeps WhatsApp/banking flows more predictable.
