Vodafone New Zealand has released new prices for mobile data roaming. It's a good step, but in my opinion it's still too expensive. The best alternative in terms of cost is always to get a local SIM card.
One of the thing in the press release though was an infographic, saying that 100 MB is good for about 400 web pages. This would be an average of 250 Kbytes per page.
The problem is that 250 Kbytes per web page is not a realistic number. Just have a look at the HTTP Archive, run by Steve Souders: the average web page size is actually 1.239 MB, about 4.95 times the number quoted in the infographic.
I looked around: Vodafone's own homepage is four times that at 1.1 MB. The NZ Herald frontpage is 1.6 MB.
The survey was conducted with Flight Centre agents who travel abroad. Their own home website is 1.3 MB.
Surely numbers sent out in an infographic should be a bit more realistic?
UPDATE: Here is Vodafone's comment on this:
As I'm sure you will be aware, the size of a webpage not only depends on the page itself but also the device you are using to access that page. For example, if viewing a media rich webpage on a laptop it will be larger than if you were browsing it on a mobile phone. I suspect that the webpages you reference in your blog were viewed from your laptop or desktop.
The stats we used in the Data Angel infographic were constructed using average values as outlined in the TCF International Mobile Roaming Guide which you can view here http://www.tcf.org.nz/library/e836af40-54d2-4f0e-9098-a69d93305282.cmr
This graphic is based on estimates, as we clearly stated in the graphic itself: "Data usage varies by device. The above examples are based on averages and are estimates only."
