How can I get a number?
I bought this it was a tracphone many years ago to use as a podcast holder for my car.
There was probably a phone number that came with it.
Where?
TracFone may be able to sell you a pay-as-you-go plan; it’s not much more than $26.00 for 2 months and you get a limited number of calls/data/texts, that accumulate if you don’t use them. But you have to remember to renew it or you’ll lose everything you’ve saved up.
I’m not sure if there are limits to how old your phone model can be, but I doubt it.
