With the gradual shutdown of 2G and 3G networks, operators will reuse these frequencies to strengthen their 4G and 5G networks. But what is happening to your smartphone? We take stock.
The end of 2G and 3G is on the horizon. But how do you know if your trusty smartphone will still be operational after this transition? Here is the complete guide to help you navigate and avoid unpleasant surprises.
The calendar in question
Orange announced the end of its 2G network for December 31, 2025followed by the shutdown of 3G on December 31, 2028.
| Operator | End of 2G | Fine from 3G |
|---|---|---|
| Orange | December 31, 2025 | December 31, 2028 |
| SFR | fin 2026 | fin 2028 |
| Bouygues Telecom | fin 2026 | fin 2029 |
| Free | (December 31, 2025) | (December 31, 2028) |
SFR and Bouygues Telecom, for their part, plan to permanently close their 2G networks at the end of 2026. For 3G, SFR has set the shutdown date at the end of 2028, while Bouygues Telecom gives it one more year, until the end 2029. Free, which uses the Orange network for roaming for 2G and 3G, will logically follow the same timetable as Orange for these technologies.
Check your phone’s 4G and 5G compatibility
The first, essential step is to ensure that your smartphone is compatible with 4G and/or 5G networks. To do this, start by looking at your phone's settings. Go to “ Settings” , Then ” Mobile network“, and finally ” Preferred network type“. If you see 4G or 5G options, that's already a good sign. Note that the option names may vary depending on your smartphone model.
A field test can also be revealing. Take your smartphone, turn off Wi-Fi and look at the network icon at the top of your screen. If you see “4G” or “5G,” your device is ready for the future. If you have any remaining doubts, do not hesitate to contact your operator's customer service who will be able to confirm the compatibility of your device.
Ensure support for 4G Voice (VoLTE)
The 4G Voicealso called VoLTE (Voice over LTE), is essential for making calls once 2G and 3G are turned off. To check if your phone supports it, look for a “4G Voice”, “VoLTE” or “4G Calling” option in your phone's network settings.
Keep in mind that some operators need to enable this feature on their end. So a call to customer service may be necessary to make sure everything is set up correctly. You can also do a practical test: activate 4G, deactivate Wi-Fi, and make a call. If you see the 4G icon stay displayed during the call, it means VoLTE is working properly.
If your phone doesn't pass these tests, don't panic. Several options are available to you. First of all, you still have time to change your phone. On this subject, consult our guide to the best smartphones, there are some at all prices.

For those who want an economical and ecological alternative, opting for a refurbished phone can be an excellent solution to obtain a compatible device without breaking the bank.
Also, don't forget to think about your other connected devices. Tablets, connected watches, connected cameras or other objects using mobile networks could also be affected by this transition. Make sure they're all ready for the big jump. This is the case for certain security equipment or on-board systems in cars.
Why 5G matters
You probably know this, but a reminder doesn't hurt, frequency bands are extremely precious and limited resources. They constitute the electromagnetic spectrum used for data transmission by wireless networks.
Each frequency band is assigned to specific uses, such as radio, television or mobile networks.
And with the gradual shutdown of 2G and 3G networks, it becomes essential to consider purchasing a 5G compatible smartphone, even if you don't immediately need this technology.
Indeed, mobile operators are decommissioning these older networks to free up resources and concentrate their efforts on more advanced technologies such as 4G and 5G. By choosing a 5G compatible smartphone, you ensure a stable and long-lasting connection.
5G networks use different frequency bands, some of which are already used by 2G and 3G networks.

By recycling these bands, operators can improve network coverage and capacity without requiring costly new infrastructure. This also helps optimize the use of radio spectrum, which is a valuable and limited resource, as explained above.
In this context, buying a 5G smartphone, even if you do not currently need this technology, guarantees you have a smartphone capable of taking advantage of these new frequency allocations, which potentially promises better coverage and better overall performance.
