Hi, my mtnl dolphin sim card from the past 10 months i.e. From march 2021, i am not receiving coverage in kerala.
Due to study related reasons i had to stay in kerala for a while and my cellphone has went to emergency mode in spite of having mtnl dolphin sim card in it, and at the same time two other devices with us using mtnl dolphin has no issues regarding network connection or network coverage
