I have always had great Optus coverage at my home in Moana St, but for the past few weeks it hasn't been anywhere near as good as it was. I have also noticed the bars on my phone never go above 3 now, generally only 2. Pretty sure that work was done on the tower very close to our place only a few weeks ago, would this have something to do with it? Or are there more people using Optus in the local area?
We don't have any reported network issues at that location. Customer can check this on our site at anytime.
Generally work on a tower should improve the coverage, not the opposite.
Are other family members/friends/neighbours also on the same network experiencing the same problem?
Have you tried restarting the phone, resetting the network settings, trying your SIM in another phone, any other troubleshooting?
What phone do you have?
Nice phone, generally a restart takes care of resetting the network.
Did you try the other troubleshooting steps and checking with others?
Phone restarting makes no difference, and I have spoken to Optus but they said no errors at their end although they were the ones that told me that some work had just been done on the Optus tower (which is only in the street behind me - hence why I probably had a nice 5 bars until I didn't). Our local facebook group is full of complaints over the mobile and broadband service so I know it isn't just me.
Okay, I'm afraid there's not too much further we can do here, particularly if Optus technical support has already looked at it.
Like you said it still sounds like an issue though, suggestion would be for yourself and members of that group to lodge a fault online.
