You got a poor signal at home on the THREE Network?
Spoken to THREE yesterday (I'm on the 3,2,1 pay as you go plan) and told them about the poor signal at home and asked them about "HOME SIGNAL", they informed me that this is only available to people "on contract".
They offered me an APP (Which is still in the BETA stage), called "THREE IN TOUCH", which allows you to call and send and receive texts over a wi-fi connection ) [using your phone number]. (They send you a text with the appropriate link).
They informed me that whilst this is in BETA stage, calls and texts are FREE, yes free. The APP goes live on the 27th July 2014. After this date, calls and texts will be charged at standard rates (i.e. 3p / min, 2p / text).
So just to let all the THREE pay as you go people know about this, thought I'd share.
