Local number portability (LNP) was once thought to be an imperative regulatory change to spur competition in the voice services market. While the service has allowed countless number of Canadians to move without having to change their phone number, the ability of LNP to spur competition, especially in the residential local competition segment, has been abysmal.Since it was introduced in the wireline world there has been little change in the residential local calling competitive landscape. No one can deny that the ILECs continue to dominate, but a lack of competition is a factor.In the wireless world, Microcell Telecommunications was the great defender of LNP for wireless operators. Its attempts to convince the CRTC to mandate the service, however, were thwarted three years ago when the commission determined that only CLECs, including wireless CLECs, could have access to LNP.Despite Microcell attaining CLEC status, the idea of offering wireless LNP fell off the radar screen because the other carriers didn't want it introduced.While there doesn't appear to be a regulatory will on the part of Microcell or any other wireless operator to re-open the wireless LNP issue, new research data may give the wireless community something to think about.A Decima Research survey of Canadians found that more than two-thirds believe carriers should be required to offer the service. What's more is that a full 35 per cent of respondents indicated that the availability of wireless LNP would be a big factor in switching to another provider. Whether a correlation can be made between wireless LNP being a factor in switching and the number of those who would be willing to switch to another provider is at best unclear.While there may be public support for the introduction of the service, it's highly unlikely that wireless operators have the financial wherewithal to implement it. Estimates have pegged wireless LNP implementation south of the border at US$1 billion.It's hard to believe that even the country's biggest supporter of wireless LNP may now be inclined to support its introduction. It could simply give Microcell's subscribers more reason to leave.
