Airtel — Network connectivity issue in Oman

Address:

Falaj Al Qabail, Sohar

I bought new replacement sim card on April, last week i came to oman for 1 month stay, when i reach muscat airport i got network connection, after i left muscat airport to another area "sohar", i lost the network connection. When i raised the complaint with Airtel, they said issue will be resolved within 1st august 2022, without any further intimation my complaint closed. Today they are telling my sim card damaged due to circuit issue, am not understanding what they are talking, am using iPhone, if circuit issue means how the phone will be in usable condition. I have enough balance and annual pack subscription with roaming pack. My mobile number [protected].
