Yes, iPhone SE models still work in 2026, but the answer depends heavily on which generation you own or plan to buy. The third-generation iPhone SE (released 2022) is still sold by Apple and fully supported. The second-generation SE (2020) runs the latest iOS and works fine on most carrier networks. The original SE (2016), however, is effectively obsolete: it cannot run current iOS, lacks critical security patches, and may struggle with modern apps, cellular bands, and battery life. This guide walks through exactly what “still works” means for each model, so you can decide whether to keep using one, buy a used one, or pick a newer device.
Which iPhone SE Models Are Still Supported?
Apple defines support through two things: software updates and hardware repair eligibility. The table below gives the quick picture, but we will explain the implications in the sections that follow.
- iPhone SE (3rd generation, 2022): Supported. Still sold new. Runs iOS 20 (current). Eligible for Apple repairs.
- iPhone SE (2nd generation, 2020): Supported. No longer sold new, but runs iOS 20. Apple still offers service.
- iPhone SE (1st generation, 2016): Obsolete. Stuck on iOS 15. No security updates. Apple considers it vintage and parts are limited.
The key cutoff is iOS support. The original SE stopped receiving major updates after iOS 15, and Apple ended security patches for iOS 15 in 2024. That means any security vulnerability discovered after 2024 is not fixed on that phone. For banking apps, email, or any sensitive data, that is a real risk.
What About App Compatibility?
Even if an app runs on iOS 15 today, developers steadily drop support for older operating systems. By 2026, many popular apps, banking, ride-sharing, streaming, require iOS 16 or later. The original SE will be unable to install or update those apps. The second- and third-generation SEs, both on iOS 20, run the full app ecosystem.
Network Compatibility
All three SE models support 4G LTE, but only the third-generation SE supports 5G. If your carrier is shutting down older 3G or 2G networks, the original SE still works because it uses LTE. However, some carriers have begun refarming LTE spectrum for 5G, which could reduce speeds on older devices in certain areas. The third-gen SE gives you future-proofing with 5G.
Are iPhone SE Models Still Usable for Calls, Data, and Apps?
Yes, for the second and third generations. The experience is not identical to a flagship iPhone, but it is more than adequate for most people.
Calls and Messaging
All three models make and receive calls and texts fine on any carrier that supports LTE. The original SE lacks VoLTE (Voice over LTE) on some carriers, which can cause call quality issues or drop to 3G in some regions. The second and third generations have full VoLTE support and Wi-Fi Calling.
Data Speeds
The second-gen SE supports LTE-Advanced, which is fast enough for streaming video, video calls, and social media. The third-gen SE adds 5G (sub-6 GHz, not mmWave), which is faster where available. The original SE supports only basic LTE, typically capped at 150 Mbps download, fine for most tasks, but slower than modern phones.
App Performance
The second- and third-gen SEs use Apple’s A13 and A15 chips, respectively. Both are fast enough for any app on the App Store. The original SE uses the A9 chip, which is now very slow for modern apps. Games, maps, and even Safari can be noticeably laggy.
Battery Life and Longevity
Battery health is a practical concern. Apple rates the original SE for about 13 hours of video playback when new. By 2026, most original SE batteries have degraded significantly. Apple offers battery replacement for the original SE only while parts last (it is considered “vintage”), and third-party batteries vary in quality.
The second-gen SE offers similar battery life to the original (about 13 hours video), but because it is newer, used units are more likely to have above 80% battery health. The third-gen SE improves battery life to about 15 hours video playback and is still sold new, so you can get a fresh battery.
If you are buying a used iPhone SE, factor in the cost of a battery replacement. For the second or third generation, that is a straightforward fix. For the original SE, you may struggle to find a reliable replacement.
How to Check If Your iPhone SE Is Still Supported
If you already own an iPhone SE, here is how to see where it stands:
- Check the model number. Go to Settings > General > About. The model number tells you the generation:
- A1662, A1723, A1724: iPhone SE (1st gen)
- A2275, A2296, A2298: iPhone SE (2nd gen)
- A2783, A2784, A2785: iPhone SE (3rd gen)
- Check the iOS version. Settings > General > Software Update. If it says “iOS is up to date” and the number is 15.x, you have the original SE. If it is 20.x, you have a newer model.
- Check battery health. Settings > Battery > Battery Health. If it is below 80%, the battery needs replacement.
- Carrier compatibility. Ensure your carrier still supports the device. Most major carriers list supported devices on their websites.
Should You Buy an iPhone SE in 2026?
If you are considering buying an iPhone SE today, the only sensible choice is the third-generation model. It is still sold new (and likely to be discounted as Apple prepares a replacement), runs the latest iOS, supports 5G, and has years of support ahead. The second-generation SE is a decent budget option if you find a clean used unit at a low price, but you will lose software updates sooner. The original SE is not worth buying for daily use.
For a broader look at what the current iPhone lineup offers, that guide covers the trade-offs between the SE, the standard iPhone, and the Pro models. And if you are deciding which iPhone model fits your needs, the SE is a strong contender for anyone who wants a compact phone, a physical home button, or the lowest entry price. Just avoid the original SE.
What About Unlocked iPhone SE Models?
Buying an unlocked iPhone SE gives you flexibility to switch carriers. The third-gen SE works with all major US carriers (AT&T, Verizon, T-Mobile) and most MVNOs. The second-gen SE is also unlocked-compatible, but some carrier-specific features like 5G (which it lacks) or Wi-Fi Calling may require carrier configuration.

FAQ
Can I still buy a new iPhone SE in 2026?
Yes, Apple still sells the third-generation iPhone SE as a new device. It is available directly from Apple, carriers, and major retailers like Amazon. The second-generation SE is no longer sold new by Apple, but you can find new old stock from third-party sellers. The original SE is not available new.
Will the iPhone SE (1st generation) work in 2026?
It will turn on and make calls, but it is not recommended for daily use. It lacks security updates, runs old iOS, and has slow performance. Apps will stop working gradually. Battery life is poor. It is better used as a dedicated music player or emergency phone.
Does the iPhone SE support 5G?
Only the third-generation iPhone SE (2022) supports 5G. The second-generation and original SE are 4G LTE only.
How long will the iPhone SE (3rd generation) receive updates?
Apple typically supports iPhones with iOS updates for five to six years after release. The third-gen SE was released in 2022, so it should receive updates through at least 2027 or 2028. Security patches may extend longer.
Can I use an iPhone SE on any carrier?
All iPhone SE models are unlocked when purchased directly from Apple. Carrier-locked models (from AT&T, Verizon, etc.) are tied to that carrier until paid off or unlocked. The original SE supports GSM and CDMA, so it works on both AT&T/T-Mobile and Verizon/Sprint, but lacks some newer bands. The second and third generations have broad band support for all US carriers.
