i got two sim. zym and eight.
i set mobile data to Zym.
then, i made a normal traditional call via phone app.
I called the bank, when i wanna update something in my bank, it sent me a push notification for the 2FA, i never receive coz zym signal suddenly gone, no internet.
den i tried setting mobile data to eight, called the bank again. zym no signal again, but this time, i can receive the 2FA push notification to log in coz i set data to Eight 4G.
why like that siol!
why when i make a call, i cannot use internet ah?
