Is it possible that those funky, predominantly Asian-owned parallel import places would have CDMA phones yet to be released in NZ? And if so, would they work?

Cheers :)

CDMA mobile handsets need a telepermit to be connected. Telecom resellers will not connect any import to the network.

It is naive.

They won't connect it because it was sold outside of NZ.

Move along.

(Just joking, not trying to be a troll)

Thanks for that guys. Can Vodafone do it because GSM is more 'standard'?

Indeed. Software on the phones differs from country to country too.

Telecom tests and certifies each mobile handset connected to its network, and suggests changes and fixes to be implemented by the manufacturer before its release in the country. There are differences in CDMA implementations from country to country, but most of the times it's a guarantee that each specific device will work.

If you purchase a GSM handset and it doesn't work, Vodafone may try and help you with some basic configuration, but they have no obligation to.

Yes GSM is a standard like 3GSM as well (W-CDMA) and HSPDA HSPUA

Also, with CDMA phones, all the legit handsets have their ESNs loaded directly into Telecoms system.

If you try and connect a phone that hasnt had its ESN loaded, the connection will be rejected.

The possibility of connecting a parallel import CDMA handset in this country is virtually nil (and you would have to defraud Telecom and break the law to do it).

1) Are the ESNs like a MAC address hardwired onto each individual phone? Maybe a hack can be made to "trick" the network into thinking the overseas phone was just the old phone, and noone would even know about the overseas phone?

2) If we had a phone that was not country/service provider locked (or we knew the SPC), would we then be able to load the NZ software loadset onto the handset, and from who?

Thanks

I think you're venturing into some dangerous territory here. It is already established that Telecom will not connect imported devices without a Telepermit. And if anyone tries to do it Telecom will be free to seek legal action.

No No No No No & No.. sorry.

I tried this recently both here and australia just to see if they would connect an overseas phone used all sorts of differerent methods to try.. all not go.

Not only will ne network not connect a CDMA phone which is not "home'd" to their 027 network, the actual phone network access methods and settings are very differerent from network to network so if you DID get it to work, it would't know what channels etc to even access.

GSM is a global standard and networks onlt vary slightly hence the ease of connecting imports. (just change the data setting and your'e away)
CDMA phones are heavily customised to the sold network are are usually network locked anyway.

Phones are not network locked. Access to foreign networks is based on the Prefered Roaming List that is embedded into the device. Each network is identified by a SID (System ID). Generally primary and secondary A/B channels do not change. The ESN is hardwired into the phone or device and this is not something that you can generally change or fake. The other part you are all missing is the AKey which is assigned against the ESN. If the 20 digit AKey does not match the 8 octet Hex ESN you will not be authorised to use the network.

From a standard voice/data/SMS perspective handsets do not really vary from network to network. What is different is the services P2T/MMS/Java or BREW.

There is a large project underway with Qualcomm and the CDG (supported by all the carriers) to standardise CDMA handsets.

Standardisation would be EXCELLENT!

I'm meaning "locked" in the form of the HOME MIN being restricted to 173XXXXXXX and there being a SPC code.

When I was in Australia recently, I just updated the Home SID/NID list to think telstra was a "home" network. It works perfectly.

thes CAN be changed among Voice codec and other neat tricks on most phone but requires a level of knowledge too beyond most users and probably most dealers too.

I HAD Successfully "migrated" a CDMA phone to the NZ 027 network on launch by simply changing these but it worked once only, they seem to have stopped allowing these foreign ESN's onto ICMS now.
