MCK Code needed

[Is57]

I'm Niharikaa from India. I purchased my Samsung J610F (J6+) plus phone from Mumbai (India) in 2019. Now I'm in Dubai since 23 March 2021. But since I have inserted my new UAE sim card from etisalat company. The sim card is not working in my device Samsung J6+ & it's showing a regional difference. It's showing to enter a MCK Code. It's an emergency & I need to make calls. It's a really bad situation. I need help. Please help me as soon as possible.

You can make emergency calls without a SIM

try checking to see if your phone is locked to the old company , some of them do this when they should'nt , mine WAS , it was locked to EE , which is naughty if them , & if so you might have to get a code to unlock it , but first try taking your sim card out & put your phone in wifi & send a quick text , then switch off & put sim back in & see if that helps .
