Add SIM card outside of a product

It seems that recently, the ability to add/register SIM cards outside of a product was taken down - is this correct? Or did it just move locations?

I am trying to add a SIM card I can use for debugging purposes/dev purposes outside of a product, but am relegated to adding a dev device within a different product which is less than ideal.

Have you tried setup.particle.io?
When you then select Electron/E Series you get this

When you hit the Activate a Particle SIM you should be able to activate a Particle SIM even without assigning it to a device.

Ahh okay, that seems like it will do what I need. Thanks!

Essentially, I’ve got a stack of about 50 “broken” electrons in various states and am trying to see how many I can get re-working…
