Title
What is Mobile number portability?
Mobile number portability (MNP) enables mobile telephone users to retain their mobile telephone numbers when switching from one mobile network operator to another.
Since its launch in Singapore in 1997, over a hundred markets allow MNP. Most MNOs offer this service for free or at a nominal price, enabling users to change numbers or switch operators effortlessly.
Infobip’s service Number Lookup can conduct automated number portability checks to service optimize routing and charging for a range of companies and industry verticals. For example, call centers seek to automatically optimize routing and costs by checking number type before establishing a phone call or sending an SMS to cut costs.
What happens to SIM after porting?
After number porting, your old SIM card will stop working, and soon your new SIM card will start working. To check if your old number works, put your new SIM card into your phone and have someone call you.
