I think some here are being "unfair" in criticizing Yackie on their pricing. Charging 24? for incoming is very reasonable since there is NO charge incurred on the back end.
Eg. It would cost 20 to 25? or more to call a UK mobile number used by many of these intl. card purveyors. Besides that, I have to maintain an account w. Kall8 (albeit only $2/mo. to forward calls to a UK (or Iceland) number. We all know what many of the charges are to call a Lichtenstein (United Mobile) number
I will definitely give Yackie a try. (Probably won't be for a few weeks.) I agree w. the statement in the "card review section" that the initial "set up" is high when compared w. some of the other offerings. It is not outrageous, tho.
As for latency - wouldn't there be some delay, for example, when - a call comes in, forwarded to my Kall8 number, forwarded to my UM number in Lichtenstein and then "forwarded" on to me when I was in Australia? I didn't notice any problem. There would have to have been more delay than if someone simply dialed my roaming T-Mobile phone directly (or an Oz prepaid). The delay wasn't noticeable to me. I didn't use UM much there last summer because of their non-functioning VM system at the time.

Make use of T-M's UMA/wifi free calling from any place in the world with access to wifi. I use an LG G6, wife an S7)
A/o Oct 20, 2013 no need for intl prepaid as T-Mobile U.S. includes voice roaming at 20¢/min (in and out)., unlimited text (in and out), and unlimited data in 140+ countries.
My Plan -[6 lines] U.S. T-Mobile unlimited minutes (incoming and outgoing), unlimited text, fast data on each line. that $145/mo. total! . (In U.S. no surcharge for calling a cell.) If a line exceeds 2G of data in a month, pay $10 more for that line. [That only happens a couple times/year.
