Switching to a cheaper deal with another network is easy. Here's how to switch providers and keep your number:
Request a switching code by text. Simply text 'PAC' for free to 65075 on any network and you'll be sent your 'porting authorisation code' (PAC) immediately via text so you can keep your number. To get a new number, text 'STAC' to 75075.
Its text must include important info, such as any exit penalties, outstanding handset costs or credit balances.
You need to give the switching code to your new provider within 30 days. You'll then be switched within one working day. You won't need to contact your old provider again.
