I believe that your problem related to the model size, because the mesh may have more than 65000 vertices. you should read each chunk of 65000 vertices and put them in a mesh peice then collect all the mesh pieces in one mesh which is the sharedmesh,
i highly recommend use this asset Simple .OBJ, it will save your time

The problem is that the script uses meshes with 16 bit indices, which only support models up to the size of 2^16 vertices. Unity however supports 32 bit indices which supports up to 2^32 vertices = ~4 billion. All you should need to do is add this line:

mesh.indexFormat = Rendering.IndexFormat.UInt32;

After this:

Mesh mesh = new Mesh();

Inside the function ImportFile.

Note that some mobile devices do not support 32 bit indices.
