Hi. We have a Bali SIM card from our recent trip to Bali and are happy to lend it to someone going in the next 5 months (as they expire after 6mths) so they can have the use of it (with the benefit of being able to get others their contact number before they leave) plus help us out by keeping the phone number active for our next trip :-)
I'll post the SIM card (which still has a small credit on it) to you with a self-addressed envelope so you could return it to us after your trip. The card will work in any NZ vodafone - just take out your existing SIM card and use this one instead while in Bali. The calls are VERY cheap and WAY WAY cheaper than roaming etc!
I will contact the first reply to this post (so please remember to include your email address)
Cheers
Sheryl (Huntly, NZ)
