Holy Shit! A valid point from a Mobile Network!
Vodafone actually have a valid objection to this.
I was involved at one of the networks in setting up the current 5-day transfer some years ago, following the debacle of the original system that took week after week after week with no-one having any real idea what was going on. The current system is a huge, huge improvement.
Attempted slamming is a problem under the current system, and under the previous one. But, it can't actually occur (without fraud where someone impersonates the customer) because:
* the customer has to request the PAC from current provider, which is then provided by the customer to the new provider within a 30-day validity period.
* the current telco **HAS** to have contact with the customer in order for the above to happen, and has the opportunity to attempt to "retain" the customer by making offers etc.
* the customer takes the PAC provided by his/her current telco to the new telco, and sets up a new account with them.
* the number is ported 5 business days following.
At any time during the process, the customer can cease the process. Because the customer MUST have contact with the current telco in order to initiate the process - no one else can do that "on their behalf" the way energy companies, landline companies etc can - it's pretty good at being proof against slamming fraud.
If the Ofcom-proposed reduction of timescales comes in, you can guarantee that they will "remove the burden of initiating the transfer from the customer" - duplicating the way things work in the energy and landline markets where customers are suckered into "just sign here to confirm I've given you a quote" and find out when they start getting bills from a new network what's happened, and that they're now in a new 18-month contract. It can be remedied, but it's a pain - both for the customer and the telcos involved (especially O2 and Vodafone who have a lot of their customers through intermediaries).
I hate to agree with Vodafone, but, well, in this instance I have to. OK, so they're only doing it to avoid costs and pain, but even so...
