I use the call forwarding in caller setting to call forward the phone number to my home. However, the reception is unstable. Sometimes my clients/friends need to call me 3-5 times to get me. I called my network provider and the technician said it is the problem of the phone. Also, the feature can't remember my "always forward" phone number. I have to do it everytime, enable it, then disable it, pretty inconvenient. Any tips to solve this problem? Thanks!!!
