I have no indoor signal and limited outdoor signal (1 bar). This has been constant for 15 years. The O2 ap does not recognise the problem. How can I source a booster to collect signal from an aerial mast and make the signal available indoors? WiFi calling works for some outgoing calls: not for incomings and text messages often arrive after 10 mins which is no good for two factor authentication.
There are no legal boosters available to consumer contract customers.
If you are in a poor signal area the only option is to move to a network who gives better coverage in your area.
