Hi
Can anyone advice me one this please. My Parent are travelling to Thailand on holiday soon. My Mum is on a O2 Pay as you go sim and her phone is a Nokia 3100 which i believe is a Tri-Band phone.
My question is: Is it possible her to make or receive calls or text messages to/from the UK using the O2 sim while she is there? I have been trying to find this out on the O2 site but am a little confused.
Any advice would be gratefully received.
