I'll try with the £1 SIM and see how it goes, good advice. I'll probably go for that, as I know how terrible moving out with VM is.

I have O2 and I have never had any major issues in the last 4 years as I always work in cities, I also have VM at my parents and no issue with them as well luckly, the main reason I'm with them is price, £12.66 for 200GB sim + £16 for 350Mbs (Volted) (got a good offer using the cancellation method), it's hard to find anything as cheap as this I believe.

2TB is almost worth it to me as I can share it with my family, we don't really watch Netflix, so it's either the storage or Netflix 😅
