I was thinking about something.
What if you will get 100 mb of data monthly for each customer you convince to join to PM.
Of course people will be eligible for that reward only if their plan are I don't know 80 $+ and ofc as soon as they are active customers.
Also to make a competition reward:nr.1 at bringing customers to PM will have a free month of services, or maybe he will get 1-2 GB of Data .
What do you think?
