For millions of users, the March 1th 2026 It won't be just any day. From that date onward, WhatsApp will stop working on a number of older phones. that no longer meet the minimum technical requirements set by Meta, the company that owns the platform.
The change will primarily affect those who continue to use smartphones launched more than a decade ago, many of them still present in Europe and Spain as secondary mobile, work terminal or device for occasional use. On these devices, the app It will not be possible to open, install, or update it.which in practice means losing access to chats, calls and files.
What changes from March 1, 2026
From that date, the application will require a minimum operating system level. Mobile devices that do not meet that requirement will not be compatible. They will lose official support and, eventually, the ability to use WhatsAppeven though they continue to function for other tasks.
According to information provided by Meta and collected in its help center, the minimum requirements to continue using the app normally are:
- Android 5.0 Lollipop or higher on phones with Google's operating system.
- iOS 15.1 or higher on Apple devices.
On devices that cannot be updated to those versions, The application will stop receiving updates and will eventually block access.First, notifications will arrive within the app itself, and eventually, it will be impossible to send or receive messages.
iPhones that lose WhatsApp
In the Apple ecosystem, the requirement is clear: WhatsApp will only work on iPhones with iOS 15.1 or laterModels that cannot reach that version of the operating system will no longer be compatible.
Among the affected phones are some models that are still seen in the hands of users who have extended their lifespan to the limit. In particular, iPhones that will lose access to the app From March 2026 onwards, they include, among others:
- iPhone 6
- 6 iPhone Plus
These devices are not capable of installing iOS 15.1, so They will not be able to run recent versions of WhatsApp which will arrive after the change. In many cases in Spain, they are still used as a secondary mobile phone, for basic calls, or as a family device.
Other older iPhones (like iPhone 5s, 5c, 4s or 4) had already been dropped in previous rounds of support cuts, and in some cases specific problems have been fixed with patches, such as the Fix for a serious vulnerability in Apple devicesSo the novelty now falls on the models that were still functioning relatively normally but have been officially left behind.
Android phones affected by the end of support
The situation on Android is broader because Many manufacturers coexist, along with a huge diversity of vintage models.All devices that fall below Android Lollipop 5.0 They will lose compatibility with the messaging app.
Among the affected mobile phones are several models that were very popular in their day, especially in Europe and emerging markets, which may still be in use as workhorse or business phones. These include:
- Samsung Galaxy S3
- Samsung Galaxy mini S4
- Sony Xperia M
- LG Optimus L7 II
- Motorola Moto E (1st generation)
These devices, launched approximately between 2012 and 2014, They no longer receive system updates or security patches by their manufacturers. Although in many cases they still power on and can perform basic functions, the software has become outdated for the current demands of the platform.
Some international lists also include other veteran models, such as certain Huawei Ascend range phones, several second-generation LG Optimus phones, or Lenovo terminals from that eraThey all have one thing in common: they run on a version of Android prior to 5.0 and have no official upgrade option.
Reasons: security, performance, and new features
Meta justifies this move as part of an ongoing strategy to Strengthen security and improve the performance of WhatsAppKeeping the application active on very old systems complicates the implementation of modern data protection technologies.
Mobile phones that have stopped receiving updates from their manufacturers They are more vulnerable to failures, malware, and other attacksIf they also run older versions of sensitive applications like WhatsApp, the situation can become a risk to user privacy.
In addition, many of the New app features require more up-to-date hardware and softwareFeatures such as improved encryption, advanced group management tools, cloud backup capabilities, and future integrations with Artificial Intelligence They need the phone to have a certain power and technical support.
From the company's point of view, concentrate resources on recent devices It allows more attention to be given to the majority of the user base, instead of continuing to maintain special versions designed for devices that are hardly in circulation anymore.
How to tell if your mobile phone is at risk
Before you panic, it's a good idea to check which operating system version you're using. This step is key to knowing whether or not your phone is in the group that will lose access to WhatsApp starting March 1, 2026.
On Android phones, you can check system information by following a path similar to this (it may vary slightly depending on the manufacturer): Settings > About phone > Software informationThe exact version of Android installed is displayed in that menu.
In the case of iPhone, the process is very simple: just go to Settings> General> Information To check which version of iOS is active on the device. If the number is lower than 15.1 and the device cannot be upgraded, future compatibility with WhatsApp is compromised.
If the phone still offers system updates but the user has been postponing them, It's best to install them as soon as possible.In many cases, a simple update to a slightly more recent version can allow you to continue using the application without problems.
What exactly will happen to unsupported mobile phones?
The end of compatibility doesn't mean an immediate, overnight shutdown, but it does have a series of clear consequences. From a certain point onward, the affected devices will experience issues. It will no longer be possible to update WhatsApp to the latest version available.
Over the course of weeks or months, the app will begin to show notifications within the interface itselfindicating that the operating system is too old and needs updating. Meta notes that these notifications will be sent well in advance to allow users time to react.
Once the deadline has passed, the application It will gradually lose functionality. until, eventually, it can no longer open or connect to the servers. That will be the point at which the phone will, for all practical purposes, be without WhatsApp.
Furthermore, since they are not receiving new versions, These devices will miss out on the latest security upgrades And without the features that will be added to the platform, reinforcing the idea that continuing to use them is not advisable from a privacy point of view.
How to back up your data before changing your mobile phone
To avoid losing conversations, photos, and files, it is essential to perform a full backup before the app stops working on the old device. It's a simple process, but it's best not to leave it until the last minute.
On Android phones, the backup is usually done in Google DriveThe usual steps are: open WhatsApp, tap the three-dot icon in the upper right corner, and enter Settings> Chats> BackupFrom there you can click on “Save” or “Make a copy now” to upload the history to the cloud.
On iPhone, the process is managed through iCloudWithin the application, you need to access Settings> Chats> Backup and select the “Back Up Now” option. This way, all messages and media files will be stored in the account associated with the Apple ID.
Before starting the process, it is recommended check that there is enough space available in Google Drive or iCloud, since chat histories with many videos, photos, or documents can take up a lot of memory; if space is limited, it's advisable clear cache or free up storage before making the copy.
Options if your mobile phone runs out of WhatsApp
If, after checking the system version, you confirm that your phone cannot be updated to Android 5.0 or iOS 15.1, the alternatives include considering a change of device or reorganizing how you use the application.
The first option is to try, as far as possible, Update the operating system to the latest official version. offered by the manufacturer. In some cases, a phone that seemed obsolete can last a little longer if it still has an update pending.
When this is not feasible, the general recommendation is migrate to a more modern phone that meets current technical requirements. You don't need to go for the latest high-end model: many recent mid-range devices offer ample support and several years of updates. If you're switching platforms, check how migrate to a more modern phone to move your chats.
Once you have acquired the new mobile phone, simply install WhatsApp, verify the phone number and Restore the cloud backup created previously. In this way, chats and much of the multimedia content are recovered, maintaining continuity in communication.
For those who use an older phone as a second device (for example, for work or as a travel phone), this might be a good time to rethink the use of multiple devices and concentrate accounts on phones that will continue to receive support.
The change coming on March 1, 2026 illustrates just how rapidly mobile technology is advancing: The phones that were the benchmark a decade ago can no longer keep up with today's applicationsMeta's decision to raise WhatsApp's minimum requirements is forcing many users to check their devices, but it also reinforces the idea that having an updated operating system, making regular backups, and replacing the device when its support expires is not only a matter of convenience, but also of security and staying connected smoothly on a daily basis.
