My sister bought an iphone 3G today (Not a 3GS, it was 2nd hand. I know the previous owner though so it has been looked after etc). Anyway, put an XT sim in it, installed the carrier bundle, and the best download speed she could manage with the speedtest.net app was .7mb/s down and 70kb/s up. The first couple of tests were less than that. I have seen people consistently hit 3mb/s+, so was wondering if anyone had any ideas. Maybe a software thing?

It is being used in Lower Hutt, with full signal. If anyone has done tests in Lower Hutt it would be great to compare! I will endeavour to add some pics of the tests tonight.

Cheers guys.

First of all narrow down the issue does the slow speed happen no matter what cell phone is attached to?

I dont have a spare xt phone that i can test the sim in. I will try a voda sim in it and see what happens. Otherwise i guess i could try it in my v3x if i get 2100 coverage on voda, will have to see...

I noticed very slow speeds on XT with my iPhone 3GS on August 14, the date you posted your message. Download speeds are back up to around 2-3 Mbps now (at least in Dunedin) on August 15. Maybe the network was taking a nap on Friday.

lol, it says I posted it on the 14th at 22:07, but I actually posted it on the 15th at 19:07 (the dates are out)

Anyway, have tried a voda sim (and had 4 bars of 3G reception apparently) in it and this is what I got:

Now I have no idea why it says about 200 miles because is I do the test on my landline it says <50 miles. Guess the traffic is being routed somewhere.

These two were taken on the wifi (with no other devices connected), which by wire gives results of about 3mb/s down and 0.7mb/s up:

Finnaly, here are two of the promised XT results:

I also have a 2degrees sim but don't really see a point in testing that....

I am wondering if it may be the test server. I notice though I am very close (20km or so) from the test server in Wellington, I always get significantly faster results on my landline connection if I use any other server in NZ. Its strange...

Did you try rebooting the phone in order to recycle the network connection?

I have since tried a server in both Christchurch and Napier. It is much faster on the wifi (about 2500kb/s down 500 up), but still only just hits 1000kb/s on 3G.

What speed are you expecting? How much speed do you need?

Now that it can (mostly) hit 1000kb/s using the other servers that is probably sufficient, but it still sometimes struggles to get up to 200kb/s, which is quite slow really. I was hoping for 2mb/s given we get such good reception here, and it is certainately not unheard of for a 3G to go that fast...

If you are curious about how fast your connection will really go try repeating the speed test at 3am. There is less chance of you having to share bandwidth with other active users on the same cell

1-1.5Mbps down and 70-100kbps up is about what I get on my iPhone 3G (2.2.1) I've gotten ~2Mbps down a couple of times but it is not common.

And I would not call 1 mbps down really slow either take the clock back a few years and these speeds were still in the lab for a mobile data network

the 1000 tests are not a problem - it is just when it is below 200-300 that the youtube seems to not stream too well. But at least it doesn't sound like there is a problem with it

That's so lame, I'm gutted you don't get massive speeds. I still can't think why? After trying my XT sim in it and getting 2.5Mbps? Weird...

Still at least you're not stuck on Voda's crap 3G which drops back to GPRS on Lambton Quay! And peaks at 500kbps in full 3G coverage. I thought the 3GS would make Voda's 3G coverage/speeds bearable but alas...
