VOIP Calls – Part 2 (retro)

So whilst looking at roaming sims, I thought I would also see if VOIP call technology or services had been updated. As well as the previous VOIP Call services I listed previously, I found 2 new ones (for me anyway): http://www.rebtel.com and http://www.jaxtr.com. Both work in roughly the same way (and there are other services that do the same thing too). Doing a quick browse it looked as though rebtel was the one that had been out longest – but it was a close contest. Of course both have iPhone and Android applications to simplify the process.
