Roaming charges are among the biggest pains in the neck of international travel. Heaven forbid we just use our phones on a compatible network owned by the same megaconglomerate that owns our network elsewhere. Noooooo, they have to charge us through the nose to make a phone call. Which is where KnowRoaming comes in.

Solve Your Problems With A Sticker

Essentially, KnowRoaming is a SIM card that piggybacks on your SIM card. Whereas before you had to buy a phone with dual SIM slots and arrange for a carrier while on vacation to make or accept calls, here you just apply a sticker with the applicator and slot it back into your phone. It stays inactive until you leave the country, and then the magic kicks in.

Paid To Prepaid

Essentially, when you arrive in a new country, the KnowRoaming sticker becomes a prepaid carrier’s SIM card. Just fill up the card, with $50 or $100 increments, and you don’t have to worry about roaming; as far as the network is concerned, your phone is legit, just probably unusually fancy for a prepaid phone. You can make calls and send texts without worry. Yes, you can even use data. KnowRoaming administers the prepaid network, so you don’t need to worry about customer service in a language you may not be great at.

Handle With Care


However, the service isn’t quite launched yet. This was originally intended to be a Kickstarter, but prototyping problems and a few other issues led them to decide that a pre-order system was a better idea. And this isn’t going to be ideal if you visit one country consistently; in that case, a dual SIM phone and a subscription are probably going to be a better idea for you.

But if you’re just going overseas occasionally, and don’t feel like worrying about your cellphone bill, this is just what you’ll need. Preorders start at $35 and arrive in February.
