An alternative to prepaid SIM cards?

Depending on the VoIP application, one should be able to circumvent blocks by creative (non-standard) port assignments. I think snidley's point was not that T-Mobile's free (but slow) international roaming data was so fantastic but rather that it was at least good enough to support some VoIP applications to provide free voice calls. Things have indeed come a long way from when I was using pay phones, triggering callbacks to make calls home. Or even going to the telephone office and being assigned a booth to make my brief and expensive call home, for which I paid the attendant.
