My note 9 is a year old and it was working perfectly fine until yesterday when all of a sudden the data just won't turn on for the 2nd sim. It's not a network issue as I swapped the SIM cards in both slots and the data works only from slot for sim 1....
BSNL. Data limit is off. when swapped the second sim to 1st slot, the data works. It was working normally till yesterday. It has this issue all of a sudden.
