Hi,
My mum and my sister are both on Vodafone. Recently, and for no apparent reason, they suddenly became unable to text each other. The texts simply aren't delivered. They can send and receive texts with everyone else just fine, but not with each other.
Both have complained to Vodafone, who's only response is to establish that since each handset can send a text to itself, then it's a handset fault, not a network issue.
My sister uses a Nokia (6500 I think, but not sure) on a contract, while my Mum uses a Samsung D600 that I donated to her when I finished my Vodafone contract, although my Mum is PAYG.
If my Mum takes her sim card out of the D600 and puts it in her ancient Nokia, the texts from my sister will get through - suggesting it is indeed a handset issue.
But what on earth could stop the D600 from receiving texts from one specific number, and is there any way of resolving it?
Thanks in advance.
