I used to own a Motorola V6 Maxx phone and I always noticed that the 3G symbol would display on my phone, but when I received a phone call, and even if I was just sitting on the couch, by the time the phone call ended it would be displaying the 2G symbol. After several seconds on standby the symbol would change back to the 3G one.

Now I own an iPhone and from what I can tell it does the same thing. The 3G symbol displays, but sometimes by the time the call is finished it just has the small circle besides 'VodaNZ' which I assume to mean is the symbol for 'not 3G' (please correct me if I'm wrong on this).

I live in Takapuna, have a strong 3G signal, and work in the inner-city suburbs which also generally have an excellent 3G signal except for a couple patchy areas which soon disappear as you drive through them. But regardless of whether I'm at home or at work or driving around it's still the same.

I can put the speakerphone on which allows me to watch the phone to see what's happening, and the bars don't drop down to nothing then spring back up again, it's just the symbol that changes.

So is someone able to explain what is going on here?

This is more common on 2100mhz and not a fault. The smallest change in radio conditions will take the call to 2g.

+1 happens to me on winmo too. Can't wait for the touch 3g that covers both the 900 and 2100

So is there any way to help stop it falling back to 2G by changing any settings in the phone? Will selecting 'VodafoneNZ (3G)' instead of 'Automatic' help to fix this?

It isn't just your phone, both my Nokias do the same.



Very annoying when you have a data session active as that disconnects as it drops to 2G (you can't have data and voice simultaneously on 2G)



Corksta try the manual selection of Voda 3G. Otherwise look for a generic (non network specific) option to only use 3G / UMTS. Just remember if you do this and go somewhere without 2100MHz 3G coverage you will have no service at all.

The NZ software for our phones are branded and you can't select 3G only (can't speak for the iPhone or the odd unbranded model). Frustrating. Anyone familiar with changing your Nokia version code (country code) can do so, then update the software if there's a new version. This will enable the option again but the process will void your warranty.

Since using 3g only I have had minimal droped or useless calls, yet on my prepay gsm phones they still continue when driving around. Often cant hear properly or they cant hear me properly and the signal is stuff all and when I hang up it comes back to good signal. Calls dont drop, they just seem to hang on to useless signals on 2g so IMO a 3g only mode is essential on a handset.

This explains the problems that I have at home.  5 bars of 3G/3.5G coverage, but poor GSM and crap voice calls.

If I bought a parallel import Nokia, could I set it for 3G only?

If it was a Symbian Series 60 (S60) one then probably. These are the mid to higher end phones.

scottjpalmer: If it was a Symbian Series 60 (S60) one then probably. These are the mid to higher end phones.

I currently have an S60 phone (6121) but there are only 2 network options - dual mode and GSM.  I had an E51 but lost it a few months ago and replaced it with the 6121 from Vodafone.  So I may get another E51 (maybe an E71) and sell the 6121.

I guess the other question is what difference does it make to have a 850/2100 dual band phone instead of one customised for the VFNZ 900/2100 frrequencies?

If you debrand the UMTS only option will come back, and all the live crap will go, so its win/win to do it.

1) Plug it into your PC with a USB cable and download and run this, it will put the newest firmware on your phone and that re-enables the ability to choose UMTS only (well it did on my VFNZ 6121c)



2) This has been answered elsewhere on the forums but . . . Vodafone NZ has 2100MHz 3G in the main cities / towns and 900Mhz 3G in the rural areas. Telecom is going to have 2100Mhz 3G in the main cities / towns but their network is going to be predominantly 850Mhz 3G. In summary - if you only want 3G in the main cities it doesn't matter for either operator, if you want the best 3G footprint NZ wide then choose 850 for Telecom, 900 for Vodafone. Note this is totally different from 900Mhz GSM which most/all GSM phones have.

Thanks Scott.  The firmware upgrade worked fine and I now have V5.11.  But I still don't have the option for UMTS only.  I note that the updater doesn't give you the option to choose a firmware version, so maybe you have an earlier version with the UMTS option?

Most annoying.

Sounds good - how do I "debrand"?

Edit:  OK, I've found a wiki on Whirlpool with all the info.  Did you use 0550551 as the product code?
