For continuous updates on which phones WhatsApp supports, check out the official Support Blog. Now we know WhatsApp is almost the number one killer App on phones — feature or smart — right now. Most users will reject a phone if it doesn’t support their favorite messaging App. Why? Because Whatsapp is a handsome, cheap replacement of the good old SMS service. So, how do you know if your phone supports WhatsApp? It’s simple. WhatsApp supports any phones that run the following mobile operating systems; Android, iOS, BlackBerry, Nokia S40, Nokia S60, Windows Phone and BlackBerry 10 according to their website. As you can tell, the company has made a deliberate effort to ensure it covers almost 80% of the phones in the market. So lets look at each operating system

Android phones

Android is by far the most popular smartphone operating system in the market taking a market share of up 81%. It’s the Windows of Mobile. The operating system runs on Samsung, HTC, Tecno, Huawei, ZTE, Sony, LG, Infinix, Innjoo, and more phone brands. Therefore its more likely that any smartphone from these brands runs WhatsApp. However, Your Android device must meet these minimum requirements: Luckily, the latest Android devices are running Ice Scream Sandwitch or Jellybean and are can SMS or call.

iOS devices

iOS is the operating system that runs Apple’s portable devices such as the iPhone, iPad and the iPod. Whatsapp does not support the iPad and iPod perhaps because they don’t support the calling and SMS functionality. But it does support the iPhone as long as it runs iOS 4.3 or later. That’s iPhone 3GS, iPhone 4, iPhone 4S,iPhone 5C, iPhone 5S, iPhone 6 and iPhone 6 Plus. Those of you who like jailbreaking your iDevices, Whatsapp can run on them, but isn’t officially supported on jail broken iThings.

Windows Phone

Whatsapp also runs on Windows Phone devices. However, your phone must be running WP 7.5 or higher like Windows phone 8 or 8.1 else it won’t run Whatsapp. That’s mostly all latest Windows Phones released after 2013 such as the HTC 8S, HTC, 8XT, Huawei Ascend W1/2, Nokia Lumia 520 series, Nokia Lumia 525 series, Nokia Lumia 620/625/720/810/820/822/920/925/1020

Blackberry

If you’ve a Blackberry, you will probably use WhatsApp more than Blackberries Messaging service itself. WhatsApp supports Blackberry OS 4.6, OS 4.7, OS 5, OS 6, OS 7 and 10. Just head over Blackberry World and download the App. If you’ve a phone running Blackberry 10, you’ll need 10.0.10.82 or later, otherwise known as BB OS Version 10.0.10.648, for your BlackBerry device. Then don’t forget that WhatsApp works with a functioning data plan, so make sure you are subscribed to BlackBerry Internet Service data plan from your network.

Nokia S40 and Nokia S60

The great thing about WhatsApp is that it works with feature phones. Nokia has some great feature phones supporting S40 and S60 operating systems. Devices running the S40 OS include Nokia 206/208/301/515, Nokia Asha 201/210/230/300/311/500/503, Nokia C3-00, Nokia X2-00/01/02 and more.  Created in 2001, the Nokia S60 is  a software platform for smartphones that runs on the Symbian operating system such as Nokia C5-03/04, Nokia N97, Nokia X6-00, Nokia E7-00, Nokia 600/700. WhatsApp has done really impressive work with porting its application across various platforms.
