T-mobile K850i 3G Internet Connection Problem

Hi,

I wonder if anyone can help. I have just upgraded to a SE K850i from a
K800i. In certain locations I am having problems connecting to the internet
on 3G most of the time where the K800 is fine. In other locations it works
fine. It doesn't seem to relate to signal strength - just area.

The difference in these locations based on a smallish sample is the phone
works reliably where an 'H' is on the display (presumably HSPDA) and
unrealiably where it displays a '3G' symbol. It could be conincidence but it
is in several loactions.

Can anyone shed light on this ? particularly as I was lead to believe that
the whole T-mobile network supported HSDPA, although someone in the
tecfhnical department say they are rolling it out.

Technical are unsure about whether it's network or phone and I only have a
couple of days if I am going to reject it. Maybe someone has some knowledge
or experience of the same. I would like to keep the phone if its not faulty
but an erring on the side of sending it back in case!

Thanks

Tony

Guy cool down, is not phone becos its work in some places. what happen
is that 3G technology expense therefore they can cover uneccessary
place like rural area so don't be afraid.

Hi, thanks for the reply but I meant it was in a good 3G coverage area and
the alternative 3G (but not HSDPA) phone worked fine. However, as you say it
works fine in some areas. Odd.

This really sounds like a signal strength thing, despite what you say
above. HSDPA requires a better signal level than 3G, so it should be
falling back to 3G only in those places where it has too little signal,
or too much noise, to run HSDPA. The difference between the two phones
would then be explained by the radio in the K850i being inferior to the
K800 in marginal signal areas.

If you are judging relative signal strengths by looking at the number of
bars on the display, it might be that the number of bars displayed is a
bit bogus and the HSDPA versus 3G thing is actually a more reliable
indicator of how good the signal is in the area you are in. It certainly
sounds more like a marginal signal problem than anything else I can
think of.

Thanks, the only odd thing about that is that throughout some areas it
always dispalys 3G and in others always H. I'm suprised the RF performance
is so different when one phone works fine and the other is unusable in the
same place. Having said that I have got a reliable dowload speed of 1.2Mb/s
in some areas!
