📶 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
- Speed test in two locations: at home and at the office/co-working space (morning/evening). Look at upload, not just download.
- Ping/jitter/loss: benchmarks — ping < 80–100 ms, jitter < 30 ms, packet loss < 1%.
- Test call for 5–7 minutes: camera + screen sharing + change location for a minute (simulate movement).
- On public transport: sit closer to the windows, have a plan B: quickly switch to audio mode.
- I transport: sett deg nærmere vinduene, ha en plan B: raskt bytte til lydmodus.
| Type | Quality | Bitrate (approx.) |
|---|---|---|
| Audio | Clear voice | 24–64 kbit/s |
| Video | 360p | 0.5–1 Mbit/s |
| Video | 720p | 1.5–3 Mbit/s |
| Video | 1080p | 3–5 Mbit/s |
| Screen sharing | Text/tables | 0.5–1 Mbit/s (extra to video) |
Tip: if the picture “breaks up”, disable HD and keep only screen sharing + audio.
🔐 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.
| Checklist “Outdoor Call” |
|---|
| ✅ Headphones + external microphone (if possible) |
| ✅ Power bank 10,000–20,000 mAh, fast charging cable |
| ✅ Backup eSIM/SIM profile, hotspot enabled |
| ✅ “Light scenario” call (no video) on hotkey |
| ✅ Short script: “switching to backup, 10 seconds” — to inform the team |
Mini cheat sheet for tests
📶 Upload at least 2–3 Mbit/s; ping < 80–100 ms
🔄 Jitter < 30 ms, packet loss < 1%
⏰ Test in the morning/evening and on transport along your route
