I have a Moto E phone which I bought from Tesco in the UK. I assume it is unlocked as it doesn't have any Tesco mobile branding on it when I turn it on.
I have already tried the manual way and it says it's up to date. But I know that a Lollipop update is coming soon, so I'm not sure whether it is available and I need a SIM to download over WiFi.
Can I upgrade it to Lollipop without the SIM card?
