The opinions expressed in this editorial are those of the author and do not necessarily reflect those of Decima Reports.  Canada’s wireless carriers and the Canadian Wireless Telecommunications Association must be as transparent as possible about the cost of implementing wireless number portability (WNP), now that they’ve taken a huge step forward in deciding to move ahead on their own instead of waiting to be mandated to do so by the CRTC (see article in this issue). While the move is certainly laudable and should be applauded by consumer groups, the industry has to make sure that the process of setting implementation milestones and the subsequent costs of making WNP available are crystal clear.  Informing Canadians about when WNP will become available is the easy part, it’s letting them know that in some way they will have to pay for it that will be much more difficult.  Report on Wireless isn’t suggesting that the carriers should report the actual costs associated with upgrading equipment or opening up customer databases to make WNP possible. But they should, at least, help their subscribers and the general public understand that having this feature available will add to the monthly cell phone bill.  The carriers did the right thing in inserting a specific line item for emergency calling service charges. The same reasoning should hold true for WNP, but logic hasn’t always ruled the day for wireless carriers.  They are currently under the threat of a massive class action suit, launched by Saskatchewan lawyer Tony Merchant, against their system access fee (SAF) practice – a single charge that encompasses a number of charges including spectrum licences and contribution, among others. It has in the past been described by some analysts as an easy way for the carriers to raise prices without actually raising prices.  Wireless operators should learn from the SAF snafu that they can’t hide charges in a single all encompassing fee and that they should be upfront with consumers on the services they are paying for.  Having a separate line item for WNP on consumers’ bills, as was allowed for contribution but never implemented, will go a long way in making sure that this is as transparent as possible.
