Internet option for mobile?

[464]

My mobile has two option of connecting to internet thru wifi & gsm SIM connection. When i am outside and if i dont get wifi connection, I use GSM (SIM) connection. When i am at my WIFI ENABLED home, i use my wifi connection and dont use gSM (sim) connection.
My question is "consider both wifi & GSM (sim) are enabled". If i try to browse internet then thru which connection the browsing will happen?will it happen thru wifi or GSM(sim)? Which connection will be given first preference WIFI or GSM(sim)?

if you're at home and you have both wifi and mobile data on it will ALWAYS use wifi
