This is a 2-part question: Let's assume that it is possible to obtain a discarded AT&T or T-Mobile smartphone that somebody is no longer using.....perhaps because s/he got a newer fancier one. In all likelihood the discarded phone will now lack a SIM card, can be "unlocked", and presumably be wi-fi enabled. So, here are the 2 questions:
1. Are my above assumptions too ridiculous and outrageous?
2. If my assumptions are not "too ridiculous", wouldn't one be able to take the "old" smartphone, insert a SIM card from a previously owned T-Mobile dumbphone, go over to a Starbucks, and get on the Internet?
Please advise, and also send copy to: email@example.com
