Krimston TWO hands-on

The iPhone is renowned everywhere, especially the latest iterations of the phone. If you’re a global trotter, it’s particularly nice that Apple equips it with the necessary radios to make it compatible to use around the world. While you can use your normal SIM abroad, it usually means incurring additional charges, just so won’t be charged extraordinary and surprise fees when your bill comes to you. Others, however, opt to pick up a local SIM and use it with their iPhone.

Well, there’s a simple solution for these particular global trotters. At first glance, the Krimston TWO looks very much like your ordinary battery case for the iPhone 6/6S, but it’s the world’s first dual-SIM solution for the phone. Dual-SIMed smartphones are nothing new, however, we still yet to have a dual-SIMed version of Apple’s beloved iPhone. This nifty accessory solves that!

Best part about the Krimston TWO is that it fashions together a case, battery, mobile hotspot, and dual-SIM functionality in one simple, solution. At the core of it is that SIM slot on the side of the Krimston TWO, which is where you place your secondary (local) SIM. Therefore, when you’re abroad, the iPhone will be leveraging the local SIM, as opposed to your usual one from home. Phone calls and text messages are all nicely handled by the accompanying app, eliminating the need to swap out your SIM card.

The Krimston TWO also acts as a mobile hotspot as well, allowing other devices to latch onto the data connection you’re using with the secondary SIM. And finally, if you just need to top off the battery, you can enable charging using the Krimston TWO’s own internal battery source. In our quick time checking it out, we realized that the Krimston TWO is definitely a product that targets a specific demographic – those who travel a lot abroad.

Right now, there’s a Kickstarter campaign where prospective buyers can make a number of pledges to pick up the Krimston TWO at a discounted rate. These early backers will be delivered a unit in August, while it’ll hit mainstream retail come November for the full outright price of $199.

Great hands-on, John Velasco! Hope you aren't going this early. It's too soon to say good bye, PhoneArena legend! :-)

Looks awkward... But cool functionality nonetheless.

Personally, I think that this is a good concept but the way they made it actually is rather "dumb". :\

Haha exactly, not to mention the fact that it won't really work well as a case since it only touches the sides of the device and there is no shock absorbent rubber or anything AND most importantly, you need to have a spare charger since from the pictures you can tell that it uses Micro USB connection...

Still worth a shot, thought.
