How can I transform all row nested rows back into normal rows bigquery?

I have a table that look like this:

Row id  edad    nombre     sector          contacto.telefono    contacto.correo 
1   275  18   dozolme      El Golf         5555555          [e-mail]
                                           123456789        [e-mail]
                                           35161631

How can I get it back to this?

Row id  edad    nombre     sector          telefono             correo  
1   275  18   dozolme      El Golf         5555555          [e-mail]
2   275  18   dozolme      El Golf         123456789        [e-mail]
3   275  18   dozolme      El Golf         35161631         null --> ? maybe null? 

The schema is:

id                  INTEGER NULLABLE    
edad                INTEGER NULLABLE    
nombre              STRING  NULLABLE    
sector              STRING  NULLABLE    
contacto            RECORD  REPEATED    
contacto.telefono   STRING  REPEATED    
contacto.correo     STRING  REPEATED    

EDIT

This is how I’m getting the output now

Answer

select * except(contacto, telefono, correo),
  telefono, correo
from `project.dataset.table`,
unnest(contacto), 
unnest(telefono) as telefono with offset
join unnest(correo) as correo with offset
using(offset)
