What is Mobile Number Portability

Sometimes mobile subscribers are not satisfied with the services of their mobile service providers but the subscribers are compelled much against their wishes to continue with the service provider as their mobile number has become very popular and they cannot afford to change their contact number as it may adversely affect their business, personal relations and may be registered with their bankers, Gmail accounts, ICRTC and in-numerous other utilities and facilities enjoyed by them to receive one time passwords.

Advice from the author

Never change your mobile number as you may lose your unsaved contacts, business, personal relations and even SMS alerts from your bankers.
If you lose your mobile set do not forget to get the SIM blocked along with IMEI number of the mobile set so that it cannot be used by criminals. Ensure lodging FIR with police
On the basis of FIR get fresh SIM for the same mobile number without effecting your business and personal contacts.
Avoid selling your old mobile set to strangers without verifying the antecedents of the purchasers beyond doubt and without valid sale agreement as whenever the purchaser uses his/her SIM with the sold set, its IMEI number gets automatically registered with the SIM user. Unsalable Mobiles sets need to be damaged beyond reuse and recycled as per law of the land.
