pennytel far to tedious, have to wait days for your charge to show up then use the code they need to make it simpler--gave up
truphone easy set up reasonable rates
tada what i've used and happy with
CALLGLOBAL APP from ideasforiphone, neat interface once their server accepted my number (4 tries) worked great to my call to finland mobile phone, no echo, very clear, just a little less quality than landline.
and i'm giving it 5 stars........4 for their app and an one extra for their customer service i sent them a email for support and they shot back a quick reply very helpful and walked me through actually i just gave them my number and next time i "registered" bingo. my wife says it sounded great.
pennytel needs to buff up their app and customer support make it easier to set up
at there website http://www.callglobalapp.com/blog/
it says it uses att lines how i don't know but the call quality is great, no wonder
so long as their rates are competitive
rates for callblobal to japan and finland mobile is 11cents 25 cents for truphone
