If I call one particular mobile number, its constantly engaged. I have no problem calling any other mobile numbers.
I can call the problem mobile number with no issue at all using any landline phone, another mobile phone using a different network provider or by using a different mobile provider on my own mobile phone.
This has been an ongoing problem for many months. I/m seriously considering leaving ID mobile because of this. Its an important contact number that I must be able to access.
Just to mention, I can’t successfully text the problem mobile number, though no issue by any other means as mentioned above.
