Mobilink has apparently adopted a policy to preserve their existing customers, instead of fetching new ones. In an effort to retain their existing customers, Mobilink today announced an offer of free minutes on first five credit reload for all Mobilink Prepaid Numbers.
For first five credit recharge through scratch card or Jazz Load (but should be more than Rs. 50) you get free minutes depending on the amount of recharge. This offer is valid until September 25, 2008.
How to Claim your Free Minutes
You can subscribe by just sending a blank SMS to 150. It is a one time subscription and will be charged at Rs. 0.25/SMS + tax
Note: You will not be able to get free minutes until you have sent the subscription SMS. So you must send it before recharging.
