Hi all we moved into a new house in an established suburb last September. The phone signal is terrible and calls either drop out completely or lose connection regularly until w-fi calling kicks in. I have a weak 4G signal most of the time but get a weak 5G at night. I want to install a booster but I know it can be an issue with the provider (Telstra) and I think only Cel-fi are approved for use.

Can anyone shed any light on the best way forward please? We only need to boost the voice calls as our wi-fi coverage is very good and very fast. We had 2 repeaters installed when we built so at least that works well! I can go through Telstra but the cost is high and I hate paying money to that organisation if I can avoid it!
