I am on Three and am generally very happy with it, but I have an ongoing issue with losing signal when I am at home or in some other places.
When I have my phone set to have WiFi on, it automatically switches off 3G data when it is able to connect to the internet via WiFi. As soon as that happens, and I see the "H" or "H+" disappear from the display indicating that the connection to the Three network is no longer HSDPA, then what also happens in quite a few locations is that the signal strength really drops. Sometimes the signal drops to zero bars, and I no longer receive text messages. If I then turn WiFi off so that the phone re-establishes data packet access, the signal strength recovers to two, three or even four bars.
Is this expected behaviour? Is Three using different cell towers for 3G data connections and for other, voice/text-only connections? Are they piggy-backing on another operator as soon as the phone is not asking for data connection?
