For a 27 minute call I was charged £80. Is it possible to do an international call Bolt on for this billing cycle to apply for that call?</P> Fri, 26 Jul 2024 16:05:15 GMT https://community.o2.co.uk/t5/Pay-Monthly/Retroactively-apply-Bolt-on/m-p/1736227#M279846 medway 2024-07-26T16:05:15Z https://community.o2.co.uk/t5/Pay-Monthly/Retroactively-apply-Bolt-on/m-p/1736229#M279847 <P>Bolt ons become active when you take them out and are valid for a month so the answer is no.</P> Fri, 26 Jul 2024 16:09:44 GMT https://community.o2.co.uk/t5/Pay-Monthly/Retroactively-apply-Bolt-on/m-p/1736229#M279847 Enlli 2024-07-26T16:09:44Z
