They say that 1mb is enough for a Skype call with Skype Mobile. I think I should try it on my Android...

P.S.: The difference between Standard and Express is only the delivery time. I got the package within 3 days because Milan and Vienna are "close" ;)

Skype to skype calls use more bandwidth than skype to phone calls. Skype uses a broad-frequency-bandwidth codec for on net calls for better voice quality.

Just made a test:
1 minute on-net call to Echo service: 550 kbyte
1 minute call to phone: 490 kbyte

One thing to note:
When talking skype-to-skype you only transmit data when you actually speak, inbetween the data rate drops significantly. While speaking i saw 50-70kbps
When talking to phones the data rate is constantly 33kbps, no matter if speaking or not.
So you can calculcate skype2phone=66kbps + overhead -> about 450kbyte/minute

Chris -
Sounds like you got the same results as Tux. Basically, 2 min. +/- per mb. Using this SIM for voice would pay in some cases. I don't know how/why they made the statement on their web site that a user would get 4 minutes/mb on Skype.

Just a note: on their Facebook page I read that they charge per 128kb increments.

What is the definition of a "session"? If you were going to make a series of calls, is that one session or several? Or, if you do a Google search and click on a series of links - is that one long session or a series that can each make you round up a bunch of short downloads?
I think I'll ask them.
I often am on a "session" where, for periods of time, no data is going up or down.

...mike

usually a session is defined from the time where your phone connects to the GPRS service (when the G, E or 3G or H symbol appears on your screen) to the time where you disconnect the GPRS service again. Most providers still have some smallprint like "at least one session rounding per day / per hour" etc.

Chris

That makes sense. Also, they should count it as a single "session" if you lose signal and reconnect within 2 or 3 minutes.

...mike

It would be nice to see, but I wonder ...

That's where unit sizes in the billing will come into the picture, and might affect people's decisions on thing like leaving an email client constantly checking or just doing manual updates a few times a day

yes, depends on the settings on the providers APN. For example T-Mobile germany holds the session open for up to 60 minutes in case the subscriber is getting out of service area and re-entering. Other providers can set different times of course.
