I 'm trying to get information about ideas to get wireless while cruising for 40 days ( New Zealand , Australia , Pacific Islands etc . My iPad is the AT&T 3G and wireless but using the ships service is really expensive . You can roam on the ships tower , but that is also pretty expensive . I just need to be able to check email and do some occasional browsing . What would be the best plan? ( get a sim card from overseas , and if so which company would serve these areas? Would it be better to just roam on the ships tower with AT&T ? Thanks for any information you can give.
