Thanks for the quick answer.
- Is it correct, that the package oriented data services GPRS, EDGE, UMTS and HSDPA cannot be used to connect two smartphones (except using CSD)?
- Is the data for CSD modulated by a modem like on analog telephone lines?
- Why is the maximum speed that much limited?

Hi

Is it possible to call an other smartphone by its phone number from a smartphone and then open an IP connection between the two devices using UMTS?
