Detailed Answer: Once our external client had a problem of mobile number swapping for the mobile sims we provided. I was given the responsibility to solve the issue. I first contacted the service provider and came to know that the sims provided and the number allotted to those sims didnt match because of some technical glitch. The solution was to resend the sim cards with correct mobile numbers. But by this time the old sim cards have reached all the cities of our state and only one day was left to close the sim cards delivery deadline. I immediately contacted the service provider and asked him of possibilities of activating the sim cards in their own locations. this facility was available, hence I gathered the details of all of our engineers to who sim cards had to be provided. I took the help of two of our team members and started calling each and every engineer and asked to go to the nearest store and replace the sim, for this we had to even co-ordinate with the central team of network provider and we succesfully closed the replacement of sim numbers in their respective locations only. By evening
we were able to close all the replacements and thus completed the task in time."
