Upgrade Android OS without SIM card 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?
No. You won't need a SIM card. Simply connecting to a working WiFi network is all you need to check and update your Moto E. Here is a post from an user on Androidcentral claiming he updated without a SIM card.
