last month (just ended for me, my plan resets on the 15th every month)
I had 542mb down and about 18mb upstream, but considering it's the first (complete) month I am using the n900 I guess my usage will shorten down to 300-400mb a month, maybe even less
This is also my first month with the N900. I have installed every possible application and manually reinstalled most of them after upgrading firmware. Like Rapante I also think my traffic usage will be lower in the future.
I have a 50 MB/day for 30 days for 10€ on HSPA. How are your data plans?
My dataplan costs 4€ for 1 GB/month, if i use more it's 4€ for each started GB.
Until now i used ~550 MB, but i'm not really sure if this is for january only or dec too...
Will see after the next bill comes.
Ususally i'm always online, i did both updates via umts, installed/reinstalled lots of progs.
i didnt count my wlan traffic, but with umts it is nearly 200 MB per month. I pay 10 € for 200 MB traffic at the umts net after that it is slowed down to normal speed
