We were being plagued by cold calls and, by coincidence, needed new phones which included a 'safeguard' system where callers have to identify themselves. Absolutely brilliant-no more cold calls.
I do like to chat to my dear sister and, if she's in the mood, we can chat away for ages (up to an hour for free then ring back).
I text and email a lot which is brilliant, so quick and convenient. Can't think how we ever managed without mobiles. I insist DH and I keep our mobs charged and switched on and on our person all day-just in case!
FaceTime is wonderful for DD who lives away so we can see each other and our dear GD too, she's only 2 but is getting used to face timing so when we do meet up, as often as we can, she knows us instantly.
