While you&#x27;re right, depending on availability of Wifi is not very portable, which decreases its utility.<p>Not sure how it is in the US, but in Romania we&#x27;ve got pretty good and cheap 4G-only Internet pre-pay cards. You can&#x27;t call or receive phone calls, you cannot send SMS, all you can do is to connect to the 3G&#x2F;4G network. The price is €5 for 1 GB, €7 for 3 GB, €15 for 13 GB of bandwidth. And you recharge whenever you want, as this is not a monthly plan. And I have an Android that I use with such a pre-pay card. It&#x27;s like my personal 4G modem that I can also use for Skype and stuff. And I was actually thinking of giving up my phone number. If it weren&#x27;t for my parents which are old-fashioned, I would.
