Make hand hold imported model?

[jeffrey.reinoso]

Hello I imported a fbx hand and an iPhone model I’m trying to make the hand hold the iphone how do I do that?

[Parmenides]

Hello Jeffrey, are you asking how to make the hand grip the phone or how to make the phone move around with the hand?

Hey! Yea how do I make the hand grip the phone 

[Parmenides]

You will need to rig the hand. This requires making joints and skinning the hand to them. Rigging is a fundamental skill necessary in Maya.  There are many tutorials on Youtube. Here is one:  https://forums.autodesk.com/t5/maya-forum/make-hand-hold-imported-model/m-p/11201001#M93568

Click on each bone joint and rotate it there.

You may have to use wireframe view or go to Shading/Xray Joints to see the rigged bones. .

Hello. @jeffrey.reinoso 
Did you Bind skin joints to model?
I can see the joint but I don't know if it already does Bind skinned. and also painted weight.

[Parmenides]

For the fingers to move with the bones you will need to bind the mesh to the bones. You mentioned the hand was already rigged. Have you tried rotating the joints? If the mesh moves with it, yes the binding is done. If no then you need to follow a tutorial for skin binding/painting.  Too complex to cover here and there are many tutorials available.

you replied to the wrong people.
If the model was rigged(Bind Skin done)joint color will change from blue to multiple colors and select object mode and the right click marking menu shows up Paint Skin Weight Tool.
