I have triple checked, I have a sim with no. +9189022 03*** of West Bengal circle on my name, As I have job here at andaman and 4G services are active here so im willing to swap my 3G west bengal sim by staying at Andaman, I have Got an empty 4G sim from Andaman’s bsnl office which is “NOT registered” in sanchar soft. Then as per self registration process i have send the SMS RE4G(SPACE)New 4G sims 19 DIGIT NO.
