Yep, and as original poster, I'll be trusting Piranha for trip to UK Wed (though also going to try out the TMob US global roaming network).
As I've posted before, Piranha has some issues texting and switching from US to UK primary numbers. But best rates out there.

More Aggressive data pricing, just received this message.

You created a whole forum account just to share that? Some people have too much time on their hands :whistling:

Whats important to some maybe not as important to others, maybe this will be more important to you:rolleyes:, just received this message.

"As from today Piranha significantly reduces call costs in may countries with Data now billed in increments of 50kb per session.:>)"

Nice news, thanks gkeeper :D On to the 10kb increments :p Piranha is getting better and better, can't fault them in any way so far :)

still some reliability issues, and texting doesn't work on UK number. Needs a cleaner way for user to decide which number is primary - I'm mostly using in Europe where people want to call and text to an EU number.

I just ordered another one. My husband is now using one as his "regular phone" (he only makes calls in semi emergencies anyway) and one for me when I'm travelling, also it will be useful on our Alaska cruise to check the occasional email when we're in ports. Hope they'll stay in business for a long, long time as I have abandoned the Truphone SIM by now....

Piranha versus Canadian Prepaid Plans
 

How well does Piranha compare to Canadian prepaid options? Same rates from Canada to Canada and the United States.
Better expiration, I imagine.
Certainly beats AT&T and T-Mobile PAYGO rates. Callinng to the USA from Canada:: AT&T's rate of 39¢ per minute and T-Mobile's rate of $0.59 / min.

Prepaid rates in Canada are around $0.25/min and $10 per 100MB on most plans. But he is such a terribly light user, that this is overkill for him... Telus is the only provider to offer pay per use data at $2 per MB and local calls are $0.30, LD $0.70.

This means that Piranha is actually cheaper considering the nationwide fee and per MB usage... and yes the no top up requirement (Telus has $100 per year or $10 per month as an absolute minimum) made it an easy choice :) He can now check the very occasional email or make the odd call which is all he needs!

Canadian number with Piranha?
 

Does he have a Canadian number with Piranha or just does not need one?
Do you happen to know what Piranha charges for a Canadian number?
