In times of forced two-factor authentication mechanisms for corporate VPN networks, community portals and online banking, the need for a SMS receiving device is unavoidable. Yet, there is a huge discomfort by entering your private mobile phone number in every form that asks for it. Pages get hacked, companies get sold,...

Maybe a prepaid SIM, a small WIFI device with SIM card holder and a neat browser based interface might be the perfect solution.
