I got a new one, now working seamlessly
I got the secure SIM with no problems. I was going to use my MasterCard debit card but apparently I have to connect it through American Express Serve, which is a slight annoyance. Then I thought, why not get a credit card? I currently don't have any but if my goal is "secure" payments then that's a better idea than linking my debit card.
Can you actually tap and pay with it? So far I've only seen 1 confirmed report of tap and pay actually working in real life.
Get the Serve card. You can drop cash into the account at the cash register at any 7-11, Wal-Mart, etc. It's instantaneous and secure since there's no link to your bank.
Got my secure SIM through AT&T, free of charge and no questions asked.

Looks like I'll have to head to an AT&T store too. I have a ticket open with Softcard, but there's been no response on their end. Maybe somehow it is the SIM that's the problem.
