There are a lot of options available for people who want to stay connected with their cellphone while overseas, but none of them are simple. International talk and data plans are expensive, and the most common method of purchasing a SIM card with a local carrier can be a hassle.
Designed to seamlessly transition your phone to a new network, KnowRoaming is actually a sticker that sits on your existing GSM SIM card. While on your home network, the sticker remains dormant, but when you cross into a new territory’s network, the device activates and sends you a text detailing local rates. The company also offers an unlimited data plan for $7.99 a day in more than 55 countries, mostly in Europe and Asia.

KnowRoaming’s value depends on how much you travel and how much you care about a seamless transition between networks. For travelers who go through a few countries in a short amount of time, KnowRoaming can be a boon, especially if you are entering remote areas where SIM access is limited. If you’re planning on spending more than a few weeks in one spot, your best bet is to get a local SIM.
