If you have 4G connections available to you, but you’re let down by the iPhone’s lack of 4G connectivity, Korean Telecom has unveiled its new Egg Series iPhone WiMAX Sleeve, the KWF-B2500. This innovative accessory might help, as it allows you to add 4G connectivity to your iPhone 4 together with a little extra battery power in the process.
The new iPhone WiMAX Sleeve adds an extra 1500mA battery power capable of providing up to an extra 5 hours of 4G surfing. But it also brings with it a little extra bulk, adding 2.4 ounces or 68g in extra weight and a third of an inch, around 8mm in extra thickness. This additional weight and thickness might be a small price to pay for the enhanced connectivity and extended battery life, especially for users who are constantly on the go and rely heavily on their devices for internet access.
Enhanced Connectivity and Battery Life
The iPhone WiMAX Sleeve is particularly beneficial for users in areas where 4G networks are prevalent but the iPhone’s native capabilities fall short. By integrating this sleeve, users can experience faster internet speeds, which is crucial for activities such as streaming high-definition videos, video conferencing, and downloading large files. The additional 1500mA battery ensures that the device can handle these power-intensive tasks without running out of juice quickly.
Moreover, the sleeve’s design is sleek and functional, ensuring that it complements the iPhone’s aesthetics while providing the much-needed technological boost. The extra 5 hours of 4G surfing can be a game-changer for professionals who need reliable internet access throughout the day without constantly searching for charging points.

Alternative Solutions for 4G Connectivity
If you’re not so sure you would like to add the extra bulk to your pocket-sized iPhone, the other alternative is to use the new Egg Series 4G Hotspot also unveiled by Korean Telecom. This portable hotspot is now 60% smaller than previous Korean Telecom WiMax portable hotspots and will provide you with up to 4 hours of continuous WiMax experience on a single charge.
The Egg Series 4G Hotspot is a versatile solution for users who need 4G connectivity across multiple devices. It can connect several devices simultaneously, making it ideal for families or small workgroups. The compact size means it can easily fit into a pocket or bag, providing a convenient way to stay connected without the need for bulky accessories attached to your phone.
The new Egg Series iPhone WiMAX Sleeve (KWF-B2500) is available to purchase from Korea for around $120 or ₩129,800. This price point makes it an affordable option for those looking to enhance their iPhone’s capabilities without investing in a new device.
The iPhone WiMAX Sleeve and the Egg Series 4G Hotspot offer practical solutions for users seeking to overcome the limitations of their current devices. Whether you choose the sleeve for its integrated battery and connectivity boost or the hotspot for its versatility and compact design, both options ensure that you can make the most of the available 4G networks. These innovations by Korean Telecom highlight the ongoing efforts to bridge the gap between existing technology and the ever-evolving demands of modern users.
