To aks how I find out what model my Sony phone is?

[ArsenalsPlayingAtHome]

Looked in settings, threw packaging away about a year ago & can't find this information anywhere!
TIA

In settings it says that the model number is G3311 but there's no other relevant information, & I need to select an option from a drop down menu - no idea which one to select.

look in 'Settings' therell be something like 'about phone ' in there
if you want imei seach in settings and it should come up

Xperia L1
