WorldSIM - cheap(er) calling when roaming?
More evidence of operator disintermediation...... WorldSIM have recently launched a SIM that is available to UK mobile users, to reduce the cost of making and receiving calls when abroad. Using callback technology, users can place a call when abroad and the the service will intercept the call, detect the destination number, then call the caller back while at the same time calling the B-party locally in the UK. Sounds quite complex, but it is currently quite a fashionable use of old technology to address a growing customer need for cheap international calling (the much PR'd Jajah works in a similar way). WorldSIM also makes it cheaper (and in many European countries FREE) to receive a call when abroad, something that all mobile operators currently charge for. In most cases, these propositions are possible by intercepting the customers call and routing the main leg of the call over IP. It then hooks in to local networks to initiate the connection at either end to the callers and recipients numbers, and connects the two calls together.
There are some significant usage and behaviour barriers to overcome with this product but provided you dont mind swapping SIMs and getting used to the caller experience, this is a great solution for saving a few quid. Also take a look at jajah, rebtel, and dialabroad.
