International Study abroad...
Suggestions for the month she's there...maybe get a local handset with a local sim?
She does have Skype on her macBook...but I'm talking about daily use..like texting and calling around in Ireland...
Do you have the unlock code for this blackberry? If you unlock it you can use an Irish SIM card for while you're over there and not have to deal with verizon's global charges.
If you go this route, you should also take the bbery off your account and replace it with a dumb phone to save you $30 for that month.
Hope this helps
Verizon has a global loaner phone program if you want her to still have her same number overseas. You can only borrow a global phone for 21 days though. probably wouldn't be ideal for you.
i think your best bet is to have her get a cheap prepaid handset and use a local sim card.
