My dd is going to USA with her bf next week for a month to stay with his extended family.
She says she doesn't want to pay for roaming, she won't need it. Fine but I still pay her phone bill so apart from a spending cap, is there anything else settings wise she needs to do? What if she gets a voicemail left, will she be charged for it?
She's on O2 SIM only. I've tried looking on their website but it goes round in circles.
