Hi. . Could you send me pac code please

Just text 'PAC' to 65075 and you will receive your PAC.

If you follow this link: https://smarty.co.uk/dashboard/settings/manage-plan

then you should see the option to leave and this should generate a PAC for you to pass on to your next provider.

You would be better contacting customer support via the online chat function in the SMARTY APP. This is a customer community with only a few moderators, no customer support.
