Call drops or goes straight voicemail

I have a huge problem with my network signal. People will claim that theyv called me and I would only find a miss call message without a missed call icon to show that I missed a call. The calls will either cut b4 I answer or I will only receive voice mail messages. This goes hand in hand with my data connection whereby I consistantly lose signal and internet pages will take too long to load.
