Bulgaria’s three wireless operators – MobilTel (MTel), Cosmo Bulgaria (Globul) and BTC Mobile (VivaTel) – are unlikely to be able to begin offering mobile number portability (MNP) to their customers from 1 January 2007, as required by current telecoms legislation. The trio have until the end of today to submit their joint proposal on how to adopt MNP to the telecoms regulator; if they fail to do so, the regulator is expected to draft the procedure itself, but this is likely to delay the process beyond the 2007 deadline. The telcos are reported by local daily newspaper Dnevik to have failed to agree on two key issues: how to route incoming calls to ported numbers and whether to establish a common database of ported numbers or allow each carrier to have its own. As it stands, Globul and VivaTel have stated their preference for the all-call query method, in which the originating network uses the routing number to route the call to the new serving network. MTel, meanwhile, has remained tight-lipped on the matter, stating only that the technological cost of the service will be unjustifiably high.
