In my opinion , the best kind of Cellular Data Plan for an    " Android  5G/4G  Cellular Laptop that can make phone calls and answer phone calls like a  5G/4G  smartphone " ,  is a package that offer       " Unlimited 5G Data "   , which is    reasonably/moderately   priced  by  the  Telcos/Network Provider . This is a good move to increase the adoption of   " Android  5G/4G  Cellular Laptop that can make phone calls and answer phone calls like a  5G/4G smartphone "    and to accelerate progress and development in a country in the field of Education , On-line Education , etc., etc.  In my opinion , the potential of  5G/4G is fully utilized more on a  5G/4G  Laptop (especially INTEL-based 5G/4G   Laptops that run INTEL-based Windows  10/11  Operating System like for example the  MICROSOFT Surface Go  3  4G  LTE    machine , not  ARM-based  5G/4G  Laptops that run ARM-based   Windows  10/11  Operating System)  when compared to a 5G smartphone . Anyway , opinions may differ .
