📶 eSIM for remote work: video calls on the go without interruptions

📱 eSIM vs physical SIM: which to choose for ‘working on the go’

🔄 Dual SIM and dual profiles

• Combo approach: physical SIM — ‘base’ (number/calls), eSIM — data profile for calls and hotspot.
• Two profiles = two scenarios: work (more data, tethering allowed) and personal (less traffic, messengers).
• Transfer between devices: save your QR/profile keys in advance, check if your phone supports secure ‘eSIM transfer’ without visiting your operator.
• Power and heat: eSIM saves space, but Dual-SIM + hotspot mode drains the battery faster — keep a power bank handy.

📊 Tariff for video calls

📈 How many gigabytes and what speed

• Traffic estimate: one hour of HD calls ≈ 1–1.5 GB (video + screen), audio calls ≈ 60–120 MB.
• Speed for stability: comfortable ↑/↓ 2–3 Mbit/s at 720p; for 1080p, aim for 3–5 Mbit/s symmetrically.
• Group calls are more demanding than single calls: add +30–50% to your reserve.

⚠️ Tariff conditions that are often forgotten

• Speed limit after N GB (shape/throttle) — check with your provider.
• Tethering/Hotspot: some plans have speed limits/restrictions.
• Roaming: check the gigabytes of ‘included’ roaming and the price for additional packages.

📡 Connection quality: how to test

📝 Quick test protocol

1. Speed test in two locations: at home and at the office/co-working space (morning/evening). Look at upload, not just download.
2. Ping/jitter/loss: benchmarks — ping < 80–100 ms, jitter < 30 ms, packet loss < 1%.
3. Test call for 5–7 minutes: camera + screen sharing + change location for a minute (simulate movement).
4. On public transport: sit closer to the windows, have a plan B: quickly switch to audio mode.
5. I transport: sett deg nærmere vinduene, ha en plan B: raskt bytte til lydmodus.

🔐 Backup internet for calls

📶 Backup options

• Smartphone as a modem (hotspot): saves you for 30–60 minutes; keep an eye on the heat, put your phone on a cable.
• 4G/5G router with eSIM: better for long sessions; place near a window, check signal levels.
• Second eSIM from another operator: in case of local network outages.

⏩ Quick switches

• Enable the auto data switching option between profiles.
• Keep the ‘tile’ Airplane mode → off → enable backup profile as a “macro” action.
• Prepare a ‘light mode’ for calls: no video, compressed screen (less traffic).

🛡 Security and privacy

• Public Wi-Fi: mobile data is better for work calls; if necessary, use a VPN.
• Noise and confidentiality: headset with directional microphone + ‘neutral’ background.
• Separate profiles: personal messengers on your personal profile, work messengers on your ‘work’ profile.
• Notifications: enable limits/alerts for traffic and balance in your operator's app.
