Obviously a handset will be useless on the Vodafone network if the user reports it stolen/lost. Vodafone will block the IMEI from accessing the network.
But what is going to happen when Telecom comes into the market with the same sought of network as Vodafone? Are they going to share a blacklisted IMEI database?
What is the case with this with places like Australia with multiple network providers? if one of their user reports a phone barred will it be barred across all the other competitor networks?
