[YackieMobile]

Hi bbob,

Thanks for your time in reviewing Yackie's product, I just wanted to clarify some issues here.

1) It's not necessarily fair to compare GSM and VOIP (look at the price difference between fixed line and mobile) To begin with, the $0.29 incoming fee does not provide Yackie with any revenue. It was a special case where it was more important to provide you with good service than make money. If Yackie was to only charge you $0.29 + a voip call then it wouldn't make commercial sense (look at what's happening around us in this market, i.e. some of the IOM products being shutdown).

2) Mexico incoming DID costs $1.54 due to the surcharge imposed on roaming customers there.

"Example Germany
Incoming =free or 0.29 through DID number
Calling France from Germany is $ 0.59 to fixed and mobile
Making a yacki voip call to france is $ 0.024 for fixed line and 0.271 to mobile.
So I would think the rate would be $0.29 + $0.024 / 0.271 = $0.314 / $ 0.561"

3) The Germany example is $0.56 for mobile, (sounds like a lot in USD) which is €0.39, lower than the new EU maximum rates.

Calling UK from austraila is $ 0.49 to fixed and mobile
4) €0.34 to the UK from australia roaming is a bargain in my opinion.

"Because of the many free incoming countries I will probably use the sim in combination with pbxes and voicetrading and setup my own did forward and callback.
Using this solution forwarded DID calls will only cost me euro 0.114 / $ 0.16 per minute."

I would like to explain here. The cost of running a GSM worldwide roaming network is very high. All we need for VOIP is a PC with some software and an internet connection. This is not the case for GSM. The infrastructure and switching equipment required is very expensive (€100.000 is pocket change in this world) Apart from that, you need interconnect and roaming agreements and quality SS7 termination worldwide. By using your international prepaid GSM phone for your own callback, you make it impossible for your operator to make any money, which is not sustainable long term.

I can only ask that anyone reading this who uses international prepaid roaming SIMs for their own callback solutions remember that if everyone were to do so, their operator would not survive.

We strive to provide high-quality worldwide roaming in 190 countries at low cost. We welcome any suggestions as to how we could improve our service.

Many thanks,

Yackie Tech
