My skitto sim otp problem

Hello, I am using an eskitto SIM and I am not receiving any verification codes (OTP) from WhatsApp and Facebook. I have already checked network, tried in another phone, verified message settings, and still the issue is not resolved. Please check if there is any issue from your end regarding OTP delivery or international SMS blocking. My number is: +8801306263619. Kindly resolve this as soon as possible.
