I want to move to TalkTalk, but they say I don need a MAC, is that correct?
If TalkTalk has unbundled your telephone exchange, then since they use a fully unbundled service to provide their broadband and telephone services you do not need a MAC. Migrating to a fully unbundled line is simply a case of telling your new broadband provider that you want to move to them, and the new provider will arrange everything. After the migration has happened it is very important to ensure your old provider knows you’ve left and the final bill needs to be settled.
