* IP addressing -
Those new IP adresses will take care of every larger combination of molecules on the earth, but those who don't, can do OK with NAT for a while, just like DSL providers do.
* Network congestion - an 'idle' GPRS terminal will still consume network resource even though there is no exchange of data.
Luckily there are simple, adaptive and dynamic ways for this ancient problem.
* Handset issues - it appears that some of the early handsets (even so-called Class B handsets) do not have the in-built functionality to maintain network sessions when non-data features are used.
Yes, early handsets are never something to profit from. For those with limited software resources, buggy organisations and software, monoslot GPRS is a way to seemingly be proud of themselves, without the capability to produce their own DSP-code in time.
It takes some basic economy of scales to produce new generations of sillycones and DSP-mips, as well as a history of actually ordering, paying for what one allocated a couple of years earlier.

However, few will actually demand GPRS services while using the voice service, tough stuff for live, pay by the minute, visual and steaming services. |
