After Lumia 640 LTE, Microsoft lists Lumia 640 XL for pre-orders online in the UK

Microsoft has listed the latest Lumia 640 LTE and Lumia 640 XL for pre-orders in the UK on its official portal. Last month, the company had made the Lumia 640 LTE available for pre-orders and now has listed the Lumia 640 XL as well.

The Lumia 640 XL has been priced at £219 ($323) and the smartphone is likely to be released in retail stores on 28 April.

However, those who are on the look out for a better deal to buy the Lumia 640 XL, can check out third-party online stores that are offering the smartphone at a significantly lower price.

The UK's major wireless network service provider EE has also officially announced that it would make the Microsoft Lumia 640 LTE available in its retail stores after it launches its Wi-Fi calling service across the country.

With Wi-Fi calling, users of the Lumia 640 LTE (and other smartphones) will be able to make voice calls over Wi-Fi even in the absence of a wireless network signal.
