3 different handsets, 3 different similar. Someone calls us we can't hear them, they can't hear us. Meaning you have to immediately call them back if it's someone you know, private number, forget about it. Now a quick search online shows this isn't an isolated thing, and vurhin are aware, bit zero fixes for it. Tried the different suggestions made, change to 3g etc but nothing helps. Rather than the usual line of its a foreign network answer, tell me why friends with us on O2, Vodafone and EE have no issues, but us, with 3 virgin contracts all have the same problem?
