Should the download size, measured in KBs, of a downloaded Web page be 
the same regardless of the carrier and cellular phone model used?

During a trip to Israel in November 2006, I rented Motorola i760 
phones from Amigo, which provides cellular service through MIRS 
Communication Ltd, a wholly-owned subsidiary of Motorola Israel. We 
were quite pleased with the quality of service and the coverage 
provided.

Unfortunately, I just received a bill from Amigo, which charged me an 
astronomical amount for Web surfing (yeah, call me a junkie, as does 
my wife, along with some other choice names).  At my request, I 
received a detail for the data charges, which indicates that each 
visited Web page equaled exactly 4KB of data.  Most of my browsing was 
BBC-Mobile News, where the standard format is primarily text, with 
maybe a tiny graphic.  I was not downloading music or video files.

I used my US cellular phone -- a Samsung A707 Sync, with service 
provided by Cingular -- to download many of the same (or similar) 
pages as listed on Amigo's detail, and my phone indicated that these 
pages seemed to average around 1300-1500 bytes, less than half what 
MIRS/Amigo claimed.

Is it possible that the size of the same (or similar) Web page could 
vary so much between carriers and cell phone models?  If not, I think 
MIRS or Amigo may be engaging in some questionable billing practices.

Thanks in advance.
