Thanks for that correction, I also thought that there was a distinction between SIMs registered before 1 Feb 2019 and after. However, using the myAIS app on my phone I can see I have a monthly limit of 7.5 Gb before reduced speed service kicks in. I can also see from the app that I have been using this number for 11 years and 1 month, so my registration certainly pre-dates the 1 Feb 2019 date. I wondered if it might be a function of using the app (i.e. it defaults to the new limits) so I also logged into my account on my PC and both the 11+ years of service and 7.5 Gb limit are there. I have no idea why. If you have any insight I would be please to know.
