Topic # 87754 5-Aug-2011 23:41 Send private message

I found a website that lists the frequencies for cellphone networks in NZ, and it said:

Telecom New Zealand Limited - 3G 850/2100
Vodafone Mobile NZ Limited - GSM 900/1800, 3G 2100
2degrees Mobile Limited - GSM 900/1800

But then in the text it also mentioned 2degrees have a 3G (WCDMA/HSPA+ 2100 Mhz) network. And Vodafone's 3G network requires UMTS 850 or UMTS 2100.

Finally Telecom use 850 Mhz , and in some major cities 2100 Mhz but it's for capacity only (?).

I work in a store where we sell 2degrees and Telecom phones, but people always ask will this work on Vodafone or Telecom or 2degrees, lol.

I got a Telecom branded cellphone to work on 2degrees today and was surprised.

I wonder, what UMTS is? But I guess 3G phones that work on 2degrees may not support 3G on Vodafone then.

And only phones that do WCDMA 850Mhz will run Telecom XT.

Would that be correct?

It seems often people won't be able to pxt or use internet when using a phone on a different network too.

Any thoughts / links / advice would be great. Thanks very much!

Vodafone NZ network

GSM 2G 900/1800mhz and UMTS 3G 900/2100mhz

UMTS / WCDMA / HSPA = 3G

LostBoyNZ: I found a website that lists the frequencies for cellphone networks in NZ, and it said:

Telecom New Zealand Limited - 3G 850/2100
Vodafone Mobile NZ Limited - GSM 900/1800, 3G 2100
2degrees Mobile Limited - GSM 900/1800



That list is incomplete. It should be

Telecom New Zealand Limited - 3G 850/2100
Vodafone Mobile NZ Limited - GSM 900/1800, 3G 900/2100
2degrees Mobile Limited - GSM 900/1800, 3G 2100, 3G 900 MHz when in a Vodafone roaming area

LostBoyNZ: Finally Telecom use 850 Mhz , and in some major cities 2100 Mhz but it's for capacity only (?).


Never count on 2100 MHz for Telecom coverage. For all effects it's a 850 MHz network only.

LostBoyNZ: I got a Telecom branded cellphone to work on 2degrees today and was surprised.


You shouldn't. Most handsets have 2100 MHz support in common. If you buy a Telecom handset it will have support for 2100 MHz, which is the main frequency for 2degrees, so a Telecom handset should work fine on 2degrees. It will also work on Vodafone, except no 3G in their 900 MHz areas.

LostBoyNZ: I wonder, what UMTS is? But I guess 3G phones that work on 2degrees may not support 3G on Vodafone then.


UMTS is 3G. WCDMA is 3G. HSDPA is 3G. HSUPA is 3G. Different names for the same thing. Long explanation, no need for it here.

LostBoyNZ: And only phones that do WCDMA 850Mhz will run Telecom XT.


Correct.

Thanks very much for that detailed reply, VERY helpful!

So for example I see the Telecom R101 does...

850 | 900 | 1800 | 1900 

So that will work on XT (850), plus 2degrees and Vodafone (both 900 / 1800). However it won't receive 3G on 2 Degrees (2100).

Since it supports 900 / 1800 though, I would have assumed it supported 3G on Vodafone (and 2 degrees when roaming in a Vodafone area), but that's not correct?

Finally one last question, do SIM cards usually automatically change the settings for internet / PXT use? I know they change the message center number automatically. But do people have to do the others manually?

Thanks again!!

If you're going to quote specs and bands you also need to compare technologies.

850MHz or 900MHz by itself means nothing as networks use both UMTS and GSM in those bands.

Sorry, I found a better website for specs on that model now:

http://www.zte.co.nz/main/R101.htm

UMTS 850, 2100 MHz
GSM 850 / 900 / 1800 / 1900 MHz

The phone only supports 900/1800 GSM, not 900 UMTS and 2100 UMTS used by Vodafone and 2degrees.

The phone will work on GSM but won't work on 3G on either network.

You are quoting the 2G (GSM) bands. You have to look at 3G (UMTS/WCDMA) bands.

It means, yes those handsets will work on 2G for those other networks, but that's just part of the story. Also  a 2G 850 MHz handset WILL NOT work on Telecom XT because it needs to be 3G 850 MHz.
