I have a Xiaomi Redmi Note 3 Pro with Android 5.1.1 and MIUI 18.104.22.168. In my settings I have the option to choose a network type. The options are "2G", "Prefer 3G", and "Prefer LTE". I only use WiFi to connect to the internet so my mobile data is off all the time although my phone automatically turns it on while downloading/sending MMS, then turns it off again). In my APN settings I have set the APN type to "mms" to ensure that my mobile data can only be used for MMS (so only my Messaging app can use data).
Does choosing LTE only affect mobile data?
I read that LTE is a faster network than 3G. Will I notice any improvements in my phone if I switch from 3G to LTE? (faster MMS download?)
Will it consume more battery?
Is my signal strength more likely to increase or decrease?
