I have an old PAYG phone (not a smart-phone) bought 2009 to replace one bought in 2008, but keeping the same sim.
I received a new sim today (4 Aug 2020) from Virgin Media, as part of their wide replacement exercise. Inserting it required Subsidy Password, which I did not have, so I filled up the web-form at www.virginmedia.com/help/unlock-code-request1 in which I listed the mobile number.
The screen reply asked me to "Please keep an eye on the phone you gave as contact number as we don't want you to miss our call". I put the old sim back and it now says "unregistered sim" and texts don't get through. How can I give a contact method?
In addition, my account now says that my plan is now Simply 8P. It used to be Daily Bonus. Is the change connected with the sim replacement amd/or with the message of 3 August 2020 saying that a mailbox had been created for my number? (I try my hardest to prevent voicemail via the mobile, but presume there will be some way of turning it off.)
