Here is my situation. I go abroad from the USA for long stretches of time. I currently use Tracfone, but since the baseline cost is about $8/mo, I stop buying time (even baseline time, i.e., no usage time) when I go away, and simply get a new (free) SIM card from Tracfone when I get back. Tracfone requires me to such a new SIM card and won't let me use the SIM card once baseline time expires. I get a new phone number every time, but that barely matters at all since I broadcast my new phone number to all my friends/family once I get it.
This has not been that big of a deal as I have an internet phone line as my main phone number, and only use the mobile phone when I happen to be away from my home - or when I absolutely need to make a call when my internet is down.
However, with Uber and the like getting to the situation in which I could realistically use Uber to get home from my airport (which is about 75 miles away
and currently requires me to use expensive ground transportation, although not as expensive as hailing a cab from the airport), I would like to be able to use Uber from the airport. But this would only work if I actually have a working mobile phone at the airport, and my current situation forces me to at least wait until I get home and get the SIM card from the mail. (Currently, Uber does not work on a regular browser and requires a smartphone.
I haven't looked into it, but perhaps I could buy a SIM (with minutes) from an airport store; this would solve my problem, and since I really rarely use the phone to *make* calls, it could be more expensive on a usage basis, so long as the baseline charge is not too high (it seems rather high for Tracfone).
Anyway, this is my situation, and I am open to any recommendations.
