Zong’s book your number (BYN) is among the popular feature offered by Zong. I think that the combination of book-your-number and mobile number portability (see the my number my network ad above) has contributed immensely to Zong’s growth. With the introduction of new numbering series Zong’s BYN will continue to attract subscribers. BYN is a good example where technology and marketing can help a company with direct growth and customer retention.

Note the limitations set by Zong:

• You cannot port-out this number to any other operator within 18 months of the purchase
• You will have to purchase and load a scratch card of Rs 300 with each SIM, you can also recharge the same amount through miniload.
• You can make a maximum of  Five bookings against the same ID.
