Getting reliable, affordable data while traveling abroad is often a headache. While international hotspots like the XCom Global are a good solution, they're an extra device to charge and carry around, and higher data speeds tend to be expensive.

KnowRoaming offers a good solution with its SIM Sticker. It attaches to your existing SIM card and allows you to get data abroad with very little hassle. The company has also brought unlimited data to more than 80 countries and partnered with TCL Communications to bring virtual Soft SIM's to Alcatel phones, providing global roaming without the need for any physical hardware.

Now KnowRoaming is bringing 4G LTE roaming to 60 countries, including Albania, Australia, China, India, Oman, Sri Lanka, the UK, and many others.

KnowRoaming users with a device capable of 4G LTE data can tap into 4G LTE for a $7.99 per day unlimited package, which is cheaper than you'll find on many competing hotspots. If you don't want the unlimited package, there are per-MB data rates and the company offers free, unlimited WhatsApp data for all messaging, voice, and video calling.

"We are excited to share our 4G LTE network with everyone," said Gregory Gundelfinger, KnowRoaming CEO. "Our team worked hard to build and deliver a robust network supporting 4G LTE that our customers can enjoy. We will continue to expand our LTE coverage across the globe, with a priority on destinations where our customers want to use it most."
