Free mobile phone service

Any one signed up for this free service?
FREEDOMPOP
They are offering 200 min, 200 text and 20 gigglybits data for free!
I've signed up for 2 sims for Mrs & me, sounds simple BUT BEWARE, they will put this 'voice premium' thing and give you the next up-grade (£4.99) for free for the first month giving you 500 of everything, but you need to cancel the free bits before the start of your next billing month if you don't want it, 'down grading' back to Basic 200 scheme.
Easier said than done IF you can see how to do it on line, if not ring them on a VERY difficult land line number to find on their site 01138870823. 02038189419 also works.
I phoned them, very helpful and got back to the basic 200, so in theory I should have 200 mins & 200 texts for free for the rest of my days!
Turned off the automatic top-ups too so I cant 'over spend'. (Nor can the Mrs!)
Their other options for higher levels don't seem too bad, but I make very few calls & texts p.m. and don't use web anything on the Phone, when she asked me if I had a Smart phone I said' its nothing special, quite nice but not what I'd call smart!'.
Sims on the way, but they may not work on my phones as they use 3's VOIP system, not cells so we will see, but its costing me nothing to try, if not back to Talk Mobile, who have been pretty good.
Freedompop might be of interest to other members, so I put it up on here.
If you Google them most of the links detailing postage, sim & connection costs are out of date as, now there are no costs what so ever.
