Yes, the SIM was activated. I’ve spent a number of sessions with the live chat to customer services but the technical support ticket they raised didn’t appear to provide any help - I only received details via customer services when I specifically asked them for a progress update. The live chats also ended up being very repetitive each time I contacted them.
The last one advised me to visit Currys so that they could check my phone - during my first visit they initially said my phone was faulty but when I asked them to test it with a SIM that was already activated, they decided that my existing SIM was the problem and replaced it. When I revisited the following day to let them know I was still only receiving an H+ signal instead of 5G they suggested I return my phione to Samsung to be checked for faults.
As part of Samsung’s pre-collection instructions I had to do a factory reset of my phone, and it turned out that this cured the problem and I’ve since been receiving a 5G signal and can access the internet using mobile data.
To recap, my wifi connectivity always worked but I was unable to access mobile data (intermittently at the beginning), reset the mobile network settings multiple times, had 3 replacement SIMS and ended up with only an H+ mobile signal.
The only fix ended up being the full factory reset of my phone with the downside being restoring the apps and settings afterwards, but at least its working now.
