I see from the JMP chat blog that you’re preparing to launch data-only SIM cards and eSIMs for Canada/US and potentially Europe. That’s awesome news!
To follow up here, I got a JMP account, and quite enjoyed it on Android. I think I’ll keep it. However, using it on the Librem 5 was a pain, and SIP phone calls barely worked (most people calling me went straight to voicemail even when I was on WiFi).
I attempted to port out my number to a few other providers from my SIMple plan, but none of us could figure it out (xfinity, JMP.chat, numberbarn, purism). Purism maintains that I didn’t need a PIN to port out, though all these providers claimed I did. When I threatened to contact Better Business Bureau, purism got me a PIN that day, but–surprise–it did not work.
I gave up and lost my number. I’m still quite bitter about it. And I will contact BBB, but I’m still not sure how I’ll word it.
Edit: I’m only just now learning that the BBB is nothing official, not a government department, but basically an alternative to Yelp.
