I might be missing something here, so please correct me if I'm wrong.
This is essentially a portable router? You buy a SIM card with a data plan, and it broadcasts a WiFi network for you to connect your devices to, right?
In that case, how is this helping poor people access the internet. They have to pay for your device, and they also have to pay for either a phone, tablet, or laptop to use that WiFi. Why, then, pay for your device at all? Phones, tablets, and laptops can all accept SIM cards directly and also be set up as a WiFi hotspot, meaning your device is entirely unnecessary. You can also buy USB dongles which give internet access for a few dollars a month. I can also do all of this with bitcoin, using either companies which accept bitcoin directly, or a service like Bitrefill to top up my SIM card.
You say the cheapest your device will cost is £30, which is around $40. For $40 on Amazon I can get a phone which will access the internet via a SIM card, whilst also performing all the functions of a phone and internet browser.
I don't see the point in this device, I'm afraid.
