This is what I found for Orange Romania...
The Internet Mobile Access service is charged differently depending on the connecting technology (CSD / 3G / EDGE / GPRS).
Connecting over the CSD technology:
* charging is made for connection time
* charging unit: the first minute is indivisible while the following minutes are charged per second
Internet (545)
charging per connection time
(EUR/min) peak 0,04
off-peak 0,02
peak: Mondayi-Friday, 08:00-20:00;
off-peak: Monday-Friday, 20:00-08:00; anytime on Saturday andSunday
Connecting over the 3G / EDGE / GPRS technology:
* charging is made per traffic volume
* charging unit: KB (Kilo Byte)
o 1 KB = 1024 Bytes
o 1 MB = 1024 KB
o 1 Byte = 8 bits
* tariff per MB: 0.9 EUR
What is CSD technology? Does the iPhone even do that? I assume I will be over 3G/EDGE/GRPS so it looks like it's around $1.00/MB, give or take.
How much data does a text message use? I did a quick search and found a simply text email is around 20KB so can I assume a text is the same or less? If so, I should be able to send/receive ~50 text messages for $1.00.
In comparison, sending a text message from Romania to the US is $0.16 for outgoing and incoming are free of charge, so the same 50 messages (assuming 25 sent and 25 received would cost about $4.00).
