Can you switch to 3g only on a S5 with lollipop?

My wifes phone craps out a ton of calls when its on 4g. I could swap it to 3g only on kitkat but cant figure it out on lollipop.

I didn't know how to do it before. But to address your problem, what size card does she have in there? When I had no card, mine would do the same. I just put an 8 gig card in it and it seemed to stop. I've got a 64 gig in it now.

Should be able to go into mobile network in settings then hit the more option. Then mobile network then preferred network type.
