I know just about zero except the name Karl Seelig - which I'll certainly remember - and it brings to mind:
There seems to be a type of man that is able to do these sorts of things - over & over.
Once I knew a couple whose husband was such a man - and he always had these brilliant plans - managed to get other folks to throw $$$ his way - always failed after putting on quite a show - then usually relocated the family at quite a distance - and did it all over again - and his failures were always 'not his fault'.
This worked until he ended up in prison, then divorced - he then switched to religion...
I have also been pretty much outright robbed by other folks in different way & times & the single common denominator, looking back - was that they all had some strong religious leanings (I do not though) which they used in making themselves seem pious & truthful when in reality they were anything but.
The only claim I make from such exposures is that it has shown me that I was too trusting in the past, and to be more careful with folks or deals that seem too good to be true.
That is actually exactly why I avoided ringplus for a couple of years after hearing about it - because it was just too far out for me to imagine it was real enough to trust - and it did turn out more or less that way too, but at least we got over 8 months of use out of the $$ it cost us to get.
What did I learn from this ??
To be EVEN more careful nowadays.
The next 'free' cellular service came along with a $29 activation fee, so it was NOT OK - but then it waived the fee and went 100% free - a serious change in status - and thus far is OK.
I don't know about Mr. Seelig & his future plans - but if I catch so much as a hint that he is involved in any company I ever use after what happened at RP, it'll be time to RUN AWAY from whatever it may be !!!
If he starts another wireless service I'd still use it if it was cheaper than what I had been using. R+ relied on people paying for extras such as more data or plan upgrades. People didn't HAVE to use their phones as much as they did. We didn't HAVE to keep upgrading to bigger plans and paying more fees. But many of us did. We also didn't HAVE to pay Member+ fees but many of us did. We chose to give R+ money. We didn't have to sign up for service with them. Was he perfect? No, far from it, but many of us got a lot out of the company for little money, and for that I'm grateful.
I don't mind paying for cell phone service as it costs companies money, and there's no way I can convince myself that a company can give that away for free year after year and still manage to pay its bills. I got about 10 months of service from R+ and paid around $200 total (one line ), so $20 a month seems reasonable to me considering how much I use my phone. I don't expect to use gigs of data every month and make phone calls and get texts without forking over any money. So yes if Karl comes up with another wireless service and I'm looking for one, I'd consider his new company as an option just as I'd consider other companies.
My guess is he'll come up with another telecom service but I doubt it will be just like R+, maybe even something for VoIP, although there is already a lot of competition in that market. It's especially hard to compete with Google Voice.
