My new FTTP product switch

[#1]

I'm about to switch to Plusnet's FTTP product next month. Can anybody tell me officially, that my existing telephone number would be held for 30 days in order to 'port' it?

Thanks

It's part of OFCOM's rules, so that's pretty official.

Thanks for the reply.  Are you able to provide a link detailing this ruling please?
