Introduction: the bottom drawer, and the 100 million devices sleeping inside it
Every French household has that one drawer. Inside: one or two still-working smartphones, a charger nobody can match to a device anymore, and sometimes a tablet. Estimates from ADEME and the collection organisation Ecosystem point to several tens of millions of phones kept unused in France — the figure usually cited is somewhere around 50 to 100 million idle devices.
These phones are not broken. They have simply lost their purpose: the plan moved to the new model, the SIM was transferred, and the device became an expensive paperweight.
Yet a smartphone with no SIM card and no subscription is not a dead object. It still has Wi-Fi, Bluetooth, a GPS chip, a camera, a speaker and — a point almost nobody understands precisely — a legal obligation to let emergency calls through.
This guide sorts out what genuinely works in 2026, what has stopped working, and the real criterion that determines the device's useful lifespan: security updates.
What still works with no SIM and no plan
Emergency calls: yes, and it's a regulatory obligation
This is the most widely misunderstood point. In France, routing calls to emergency numbers (112, 15, 17, 18, and 114 for deaf and hard-of-hearing people) falls under obligations set out in the French Post and Electronic Communications Code and overseen by Arcep.
In practice, on a phone with a SIM but no active plan (cancelled line, exhausted prepaid credit): emergency calls go through. The network accepts the connection even if the subscription no longer allows anything else.
On a phone with no SIM card at all, it's more nuanced. The lock screen does display "Emergency call", and the call is technically placed over whichever network is reachable. But:
- the call goes out with no usable subscriber identifier, hence no callback number;
- emergency services cannot call you back if the connection drops;
- the automatically transmitted location (AML, Advanced Mobile Location) is less reliable.
A phone without a SIM is an acceptable emergency stopgap. It is not a dependable safety phone. If the goal is to put together a backup mobile for an elderly relative or for the car, leave a SIM in it — even a prepaid one costing a few euros.
Wi-Fi: almost every modern use case
Without a SIM, a smartphone remains a full internet terminal as soon as it joins a Wi-Fi network. That covers:
- web browsing, email, online banking;
- WhatsApp, Signal, Telegram, Messenger — provided you were able to validate the sign-up with a phone number once;
- audio and video calls through those apps;
- internet-based messaging, including sending a text from a website to a French mobile number;
- Google Maps or Organic Maps with maps downloaded for offline use;
- music, podcasts, audiobooks.
For a phone that permanently lives at home, that is more than enough. And for a device set up in a fixed spot — kitchen radio, recipe screen, smart-home remote — a small adjustable smartphone stand turns the object into a useful piece of equipment rather than a phone abandoned on a worktop.
GPS: it works without a network, contrary to the myth
The GNSS chip (GPS, Galileo, GLONASS) is a passive receiver. It listens to satellites; it transmits nothing and uses no data. So a smartphone with no SIM locates itself perfectly well.
What does require a network is the base map. Hence the solution: download offline maps before you leave. An old smartphone then becomes a perfectly respectable hiking or car GPS, provided you solve the battery-life problem — in a car, a simple car phone mount with charging is enough to keep it going all day.
What no longer works — or won't for much longer
Standard texts and calls: no, except over the internet
Without an active SIM, no text message goes out over the mobile network. There is no trick around it: SMS is a carrier service, tied to a subscriber identified on the network.
Two workarounds exist:
| Need | Solution without a plan | Limitation |
|---|---|---|
| Send a text to a French mobile | Web-based SMS sending service | Replies cannot be received on the device |
| Ongoing conversation | RCS (Google Messages) or encrypted messaging over Wi-Fi | The other person must use the same app |
| Call a landline or mobile | VoIP apps with a virtual number | Often paid, quality depends on the Wi-Fi |
Worth noting: RCS, which is gradually replacing SMS, generally uses a phone number as its identifier. Without an active line, RCS registration is unstable at best. Arcep has in fact documented the continuous decline of person-to-person SMS in France, precisely in favour of these IP messaging services — which paradoxically makes a SIM-free phone more usable today than in 2015.
Wi-Fi calling (VoWiFi): no, not without a line
Many people hope the "Wi-Fi calling" feature will save the device. It won't: VoWiFi is a service tied to a subscription. The phone authenticates with the carrier's core network using the SIM's credentials. No SIM, no VoWiFi.
2G and 3G: the window is closing
For the oldest phones — those that only support 2G/3G — the question of a plan becomes secondary. French carriers have begun shutting down 2G and have scheduled the 3G shutdown for the end of the decade. A device unable to handle VoLTE (voice over 4G) will eventually be unable to make calls at all, even with a perfectly active SIM.
The quick test: in the network settings, if "VoLTE calls" or "4G calling" doesn't exist as an option, the device is at the end of the road for any telephone use.
The real longevity criterion: security updates
This is where the decision to keep or recycle is made. A smartphone that no longer receives security patches accumulates known, unfixed vulnerabilities, month after month.
Actual support periods in 2026
The landscape has changed considerably, notably under pressure from the European ecodesign regulation for smartphones, applicable since June 2025, which requires manufacturers to provide a minimum of five years of security updates after a model leaves the market, as well as spare-part availability.
Typical figures observed:
- Apple: 5 to 7 years of iOS updates, plus security patches beyond that.
- Google Pixel and recent Samsung Galaxy S/A models: up to 7 years announced on models released since 2023-2024.
- Earlier mid-range devices: often 2 to 4 years, sometimes less.
What to do with an out-of-support device?
Three strategies, in decreasing order of caution:
- Restricted use: the device is only used for tasks involving no sensitive data — alarm clock, radio, audio player, remote control, photo booth. No bank accounts, no two-factor authentication on it.
- Fully offline: Wi-Fi turned off, local use only (stored music, offline maps, notes). The risk becomes close to zero.
- Alternative ROM: on some Android models, community operating systems such as LineageOS or /e/OS extend patches by several years. The operation isn't trivial, but documentation is plentiful and the standard reference material on smartphone security explains the trade-offs well.
A simple, non-negotiable rule: an out-of-support phone should never host your banking app, nor receive your two-factor authentication codes.
Six practical uses for a smartphone with no plan
1. Home security camera
An IP camera-style app turns the device into a monitor for your living room, your letterbox or a baby's room, with motion detection and notifications sent to your main phone. It needs constant power: a USB mains charger with a long cable avoids having to stick it next to an awkward socket.
2. Baby monitor or home intercom
Same principle, in audio mode. Two devices linked over Wi-Fi through a dedicated app replace an €80 baby monitor.
3. Dedicated audio player
No SIM, no notifications, no social media: the device becomes a music player again. For sport or travel, pairing it with Bluetooth headphones makes a perfectly functional setup, and spares your main phone's battery.
4. Backup phone in the car or in a hiking bag
With a low-cost prepaid SIM, this is the best possible use: a second charged device, with offline maps, that you needn't worry about dropping or losing to theft. A 10,000 mAh power bank in the glovebox rounds out the kit.
5. A child's first device, with no line
A Wi-Fi-only smartphone with no SIM is an excellent compromise for a child of 8 to 10: games, video calls with family, photos, but no mobile data connection outside the home and no possibility of premium-rate texts. The device becomes controllable through the simple geography of the family Wi-Fi.
6. Secondary screen and smart-home remote
Mounted on the wall in the hallway or the kitchen, it displays the thermostat, the cameras, the weather, transport times. A wireless charging dock gives it the genuine status of a fixed appliance.
Before repurposing the device: four mandatory steps
An old smartphone holds ten years of digital life. Before giving it away, parking it in the hallway or handing it to a child:
- Check for carrier locks and manufacturer locks. On an iPhone, turn off "Find My" and unlink the Apple account; otherwise the device stays tied to its former owner and becomes unusable. On Android, remove the Google account before resetting.
- Perform a factory reset, then set it up again with a dedicated account — not your main one.
- Deregister the IMEI from your sensitive services if the device was registered as a trusted device for your bank or your email.
- Assess the battery's condition. A swollen battery, or one that heats up, is a fire risk, not a saving. In that case, either replace the battery (a smartphone battery replacement kit, or a trip to a repair shop), or drop the device off at a collection point.
And if you don't keep it: recycling isn't a vague option
In France, every retailer of electronic equipment has a take-back obligation. Collection points are listed by Ecosystem and by the public WEEE management service. A smartphone contains gold, copper, cobalt and rare earths: leaving it in a drawer is, economically, the worst option of all. Resale on refurbishment platforms still has value for models less than six years old.
Quick decision table
| Device situation | Verdict | Recommended use |
|---|---|---|
| Under 4 years old, still updated | Keep | Full second phone, prepaid SIM or dual SIM |
| 4 to 6 years old, updates stopped | Keep with restrictions | Monitoring, audio, GPS, smart-home screen |
| Over 6 years old, no VoLTE | Stop using it for calls | Strictly offline use, or recycling |
| Swollen battery, broken screen | Don't keep it as is | Repair or collection point |
In summary
A smartphone with no plan in 2026 isn't a diminished phone: it's a pocket computer on Wi-Fi, which retains access to emergency calls, GPS, internet messaging and web-based text sending. What it loses is precisely the three services the carrier bills you for: mobile data, standard calls and network SMS.
The real limit isn't the lack of a subscription, it's the end of security updates. As long as the device is up to date, it can do everything. After that, it remains highly useful — provided you take away the keys to your financial life.
