I was really surprised when I couldn’t find the 3g connection when sliding the top bar.
Samsung Galaxy Pocket has the “silence mode” option instead of the 3g connection from the top sliding bar.
To enable the 3g connection, go to “settings” > wireless and networks > mobile networks. From there, enable “use packet data”. That is the 3g connection.
Don’t touch the other options from mobile networks.
