About those great new cap plans with Telstra... yeah, you can't switch to them if you're a long-standing existing customer. For a while, anyway.

You know those great new Telstra mobile cap plans we wrote about
on Monday? You know, the ones that actually make Telstra price competitive with all the other networks?
Oh, "about time", do I hear you say? "I've been a Telstra customer for ages and I've been waiting for them to bring pricing up to date?"
Bad luck, buddy. Chances are you're on Telstra's old billing system, not the new Siebel system that was instituted by Sol Trujillo and co, but has been an IT implementation nightmare that drags on to this day. And if you are on the old system, you can't get on the new cap mobile plans.
Instead, you have to ring customer service and make an "expression of interest" in the plans. Telstra's IT team will then -- at some point -- migrate your customer account to the Siebel system and let you get on the new plan.
In the meantime, you'll be stuck on the old plan with half the call credits and no data, and Telstra won't give you any compensation for its own internal system issues.
Telstra spokesman Craig Middleton pointed to a line of fine print in Telstra's advertising of the plans: "Next G Cap Plans only available to new customers or customers with a 13 digit account number."
So, if your account number is one of the 10-digit ones, indicating you're on Telstra's old system, prepare to be shafted for however long it takes for Telstra to get round to migrating you to their new system.
We asked Telstra for further background to the issue, and Middleton said: "We are nearing the end of our migration and the reality is that we have a small proportion of customers remaining on our old systems."
"We will work with individual customers to ensure they are able to connect to the plan that suits their needs," he said.
Just as long as customers don't want to change to one of the new Next G cap plans immediately, that is.
Telstra would not comment on why it could not change existing customers in the old billing system to the new plans.
Telstra is able to sign up new customers porting from other networks to the new plans immediately, however.
