Random I know... but Mumsnetters know everything.
My parents are going on holiday to Goa for 3 weeks and my 92 year old Gran is so upset because she thinks they won't be able to talk to her. She doesn't have a mobile, only a land line. Using their mobile phones when out there is not an option (they've checked on the o2 website and I think they had to add something that cost £120 a month?!) or something daft like that.
I'm hoping they'll be able to maybe get a phone card and call on a phone box like everyone else used to. However my Gran is convinced it'll cost loads so has resigned herself to not hearing from them for 3 weeks 
Anybody any experience? if like to reassure her. thank you!
