One of the most exciting hacks available for the older 3G-capable Amazon Kindle was the ability to use its global SIM capabilities in an emergency via SSH.
As US telecom companies shut down their 3G networks over the years, that capability died out.
However, there is a way to get a genuinely global SIM for £22.99 (about $30): here is how we did it.
Meet RWG
RWG is a mobile virtual network operator (MVNO) based in Wales that specializes in IoT (Internet of Things ) connectivity. IoT is the umbrella term for connected things like e-scooters or smart meters, many of which use data-only SIM cards.
The one that caught my attention is the 5-year SIM data only
Now, 100 MB per month doesn’t sound like a lot. Netflix, even on its lowest settings, consumes 170 MB of data per hour , but if all you want to do is send text messages (not SMS) or small data packets (which is what IoT is all about), then this is a great solution. 1MB is enough to send about 10,000 WhatsApp messages if that’s your thing (or about an 8-minute voice call in our rough test). Videos and pictures consume a lot of data and should therefore be avoided.
Global? Really?
In a short conversation with the support team at RWG Mobile, we were told that we could use the SIM in most global territories, except for several countries (Iran, Iraq, North Korea, Venezuela, and Yemen). Russia and Cuba are not on the list, while Venezuela is a surprising addition.
Since you can buy more than one SIM, you could technically get two of them in a mobile device (there’s no restriction about using it in a smartphone or a tablet, we’ve been told) or in a Mi-Fi /4G Hotspot device and swap them (although that could get messy).
Anyone, even those living outside the UK, can buy the SIM, and the only constraint is that it must be activated in the UK before leaving for a foreign country. It accepts a variety of international credit cards (JCB, Discover, Diners), but not American Express.
You also don’t have to register the SIM card, which means that you don’t have to pay extra if you go over your 100MB limit.
How do you use a global SIM?
The obvious answer is that you can use it as an emergency data SIM, but bear in mind that it will be useless in feature phones as (a) it is a 4G SIM card and (b) it cannot be used to make calls or send text messages.
If you are a frequent traveler, it will provide you with a transient SIM that will be handy for booking a cab or finding your direction, but just bear in mind that it is no substitute for Wi-Fi if you can find it.
A global SIM can also be used inside a GPS tracker for a variety of things, like luggage tracking, should the worst happen.
