Cruising altitude, aeroplane mode on, phone tucked in the seat pocket — and the Even G2 still calmly shows the time and your notes. This is the exact spot where two things people muddle together come apart: "no phone nearby" is not the same as "no internet". In the first, the Bluetooth link drops; in the second it holds, and only the route to the wider network is missing. That distinction changes a surprising amount.
Short answer: As long as the phone is in Bluetooth range, everything phone-side works without internet — notifications mirrored from your handset, a teleprompter script you already downloaded, capturing QuickNotes, the time and the display. Anything that needs the internet goes quiet: live translation is cloud-based per Even, and so are the AI prompts. The glasses don't turn stupid offline — they just lose the features that were always computing in the cloud.
The one boundary that matters offline: the cloud
The Even G2 is a camera-free display tethered to your phone. Some of its features do their thinking on the handset itself; others send data to a server and wait for the reply. Cut the internet and nothing changes for the first group and everything changes for the second. So it isn't about whether you're in Switzerland or Japan — it's about whether, in this precise moment, a line to the outside is open.
That's the most useful sorting we can hand you, because it covers every situation the same way: a plane, the Gotthard Base Tunnel, an underground car park, an alpine valley with no bars, a hotel Wi-Fi that has just given up.
What runs, what goes quiet
"Phone-side" means it runs on your device and works wherever the device does — including with no signal at all. "Cloud" means it needs a live internet connection, or the feature simply waits on nothing.
On the phone
Anything stored locally or computed purely on the device.
- Time and display — the basic readout needs nothing from outside.
- Downloaded teleprompter scripts — pushed from the app in advance, they run self-contained.
- QuickNote capture — recording works; any transcription can catch up later once you're back online.
- Navigation with offline maps — GPS works without a network; if the maps are pre-loaded, turn-by-turn cues keep arriving.
- Mirrored notifications — whatever your phone raises as an alert, it relays to the glasses over Bluetooth (with one caveat, below).
In the cloud
Anything that has to ask a server in real time.
- Live translation — cloud-based per Even; with no internet there's no translation, on the lenses or in the app.
- AI prompts — the assistive suggestions compute online and stay silent offline.
- Freshly arriving messages — the glasses aren't the problem; a message can't reach a phone that has no connection in the first place.

The honest subtlety about notifications
"Notifications work offline" is true — with a nuance worth knowing. The glasses mirror whatever surfaces as an alert on your phone. A calendar entry, an alarm, a timer: those are generated locally and appear on the lenses even in aeroplane mode. A fresh WhatsApp or a new email, on the other hand, has to reach your phone over the internet first — with no signal it never arrives, so the glasses have nothing to mirror. That's not a weakness of the glasses; it's the plain physics of a missing line. The moment the phone is back online, the backlog of alerts trickles in and the glasses show them as usual.
Prepare before the signal dies
The good news: almost everything that counts offline can be loaded in advance. Make that a habit and you'll barely notice the missing network.
Before a flight or a tunnel: push your teleprompter script from the app to the glasses while you still have signal, and your talk is with you above the clouds. Download the region's offline maps in your maps app so navigation carries on without a network. And plan firmly around live translation going silent on the plane or in the Gotthard Base Tunnel; if you expect a language barrier there, sort it before you take off.
Don't confuse this with "no phone"
The difference is decisive. Leave the phone on your desk and step out of Bluetooth range, and the glasses lose the link to their brain — nearly all the live behaviour stops. Keep the phone with you and lose only the internet, and the Bluetooth bridge holds, so the whole phone-side half keeps working. "Offline" in this sense is the kinder case: you lose the cloud, not the connection. How much survives when the phone isn't with you at all is its own question — one we answer separately rather than lump the two together.
So: buy, skip, or test first?
Buy without worry if your day is notifications, notes, teleprompter and navigation, with translation as a bonus. Those core features carry you through any dead zone, as long as you load ahead.
Pause if your single reason to buy is translation exactly where there's no network — on the long-haul flight, deep in the tunnel, in the remote valley. That's the real gap, and no setting closes it.
Test first if you want to feel what offline is actually like. Put the phone into aeroplane mode in the Zürich showroom and see for yourself what remains. If it's specifically translation reach you're weighing, our translation-glasses overview goes deeper; for a model-by-model view the AI glasses database helps, and the wider decision is what our buying guide is for.
