Our experiences with ting were all consistent AND disappointing.
Their line fee does indeed make it uneconomical - but that is not the worst of it IMO.
A combination of their tiers and the ways they handle accounts assures overbilling in their favour.
Ting delays things such that is is highly likely for users to be billed another line fee for a line that has ported away; they also seem to sort of accidentally delay port outs.
The extreme disappointment we had over the reversals of the various 'bonuses' they offered, then withdrew was bad enough - but then seeing how much it cost for the least amounts of usage was shocking - and finally getting away from there AND getting billed again for lines that no longer existed there...sheesh.
The amounts of time required just to get them to release lines for porting, reverse over-billed charges and verify that the account was closed with no further billing possible was yet another very poor 'feature' of this service.
Last of all was the line we sort of inherited from a friend who no longer wanted it that went there from rp...
It had a $40 top-up on it, and combined with the various offers of goodies from ting - should have been free long enough to see that post as a credit...sure, uh-huh.
No such luck.
The phone had maybe 20 minutes of usage & maybe 3 SMSs, and that gobbled up most of the join-up credit; month 2 had zero usage and that ate up almost all the rest - so rather than pay to see if they'd honour their top-up transferral offer, it was time to port out (to Cellnuvo, of course...).
Oddly enough the port-out was delayed long enough for billing to occur - which then takes days to appear (assuring that you'll stay another billing period as the $6 charge happens immediately), and no amount of cajoling them got that port to finish - so that line had to be cancelled outright to avoid the $6 charge for nothing - and even THAT was a hassle.
Good thing that the phone used for that line is essentially a throw-away that we do not need, because it may or may not still be tied up there or caught in-between porting out and porting in.
All things considered - we would ONLY recommend using ting for someone who has a really nasty temperament & enjoys yelling at others - thankfully though, we have no such folks that we associate with !!
At the end of the day perhaps karma will find its way to visit some deserved balance upon that company;
I can say with a clear conscience that such a visitation would be good for a snicker or 2.
