Sir, my sim card had been deactivated without my permission. I am staying in my my native so whenever i use to visit there, i use my docomo sim but now suddenly when i entered my number to get it recharge it gave me a pop up message that "the number is not valid". I am npt able tp recharge it. Please activate it soon. Its really very urgent. How can they deactivate my sim without my permission. I know i use that sim oftenly but that sim number is very important for me because i have many accounts linked on that number. I just want my number to be activate thats all.
Thanks a lot, if this platform helps me to resolve this issue.
