The last 2 days I have been having major issues with coverage with one or no bars showing on my phone at home, normally 2 or 3 bars. This is impacting on my business as this is the phone I use for work calls and many are done from home. I have been forced to communicate with customers via text which is terribly unprofessional. I have checked the coverage issues page and none are showing in our area. My postcode is 3385 Taupo. Help please.
