I don’t change phone as often as most people, so the tech may have changed since last time I did it. I’m moving from a Samsung on Android Gingerbread to a Moto on Pie, so it’s quite a leap and I needed a new micro-SIM, but I’m sticking with GiffGaff. Neither the instructions for changing SIM or for changing phone with the same SIM make sense. I have numbers in the phone, the SIM and Google.
My first thought is to temporarily synch everything I can to Google and see what’s missing when my number arrives on the new phone but that sounds like it might involve some future pain with no way back to rectify mistakes. I think I have some ancient Windows software to move to a new Samsung phone. I refuse to do the naff “Send me your digits” thing. I’d be grateful for any advice.
