Jordanian registering for UK personal allowance then transfering to husband

Can a Jordanian resident with a Jordanian passport register for the personal allowance (despite having no income in the UK) and then transfer part of the allowance to their husband? It keeps saying the only way to discuss marriage allowances for overseas applicants is to call, but when you call it doesn't get answered by a human even if you wait.

Hi,

Yes, you are entitled to personal allowances and if not fully utilised, you can transfer 10% to your husband.

Thank you.
