Can I upgrade any HP Notebook to support WWAN Service?

Not every model of HP notebook can be updated to support WWAN. New units of specific notebook models may support WWAN, however, the older unit of the same model may not have a WWAN antenna, SIM slot, or WWAN module slot installed. You can refer to the user manual if your model can be upgraded to support WWAN.
