My calls have been dropping for the past month and half. After contacting telus they sent me to apple and apple gave a replacement device . But it is still happening and telus doesn't wanna do anything about it. All they are is sorry . If I wanna cancel the contract they even want me to pay for the cancelation fees. such a stupid company . i have been with them 4 years .
There are a number of different things that can cause calls to drop. Your post didn't include any details.
