Hi, not sure if this is the correct place to post or not but.....

Just bought a parallel imported Z1 Compact online ( reputable dealer in AK ) and it doesn't appear to want to connect to the Spark network with my Sim. Well I say does not but it has a couple times and then the network drops off again. Have sent a text, made a phone call but then it drops off again. Sim worked fine in my old Z1 ( before the screen cracked ) and in the Motorola Defy I used in the interim.

It doesn't appear to be locked as it found the Spark network a few times, Skinny, Vodafone and 2 Degrees also. Checked the IMEI number out, all fine. Factory rest made no difference. Am I missing something blatantly obvious here?

Searching for network operators turns up 2 Degrees in 2G and 3G as well as VF 3G, sometimes Telecom(?) and very occasionally Spark. But never long enough to be reliable. I have tried all modes for searching for networks, but Spark popped up on WCDMA preferred which is correct I think?

Before I send it back is there something else I can do?

Cheers
Chris

The handset needs to support 3G / WCDMA 850Mhz for Spark coverage I suspect the handset is only seeing limited 3G 2100Mhz capacity sites

Thanks John, any way of telling if this is the case?

I also have Z1C and have no of the issues with connectivity, even 4G (tried on both vodafone & spark network)
I suspect you have either a faulty device, or (not sure about this) a version that does not cover the frequency that johnr mentioned.

If they have a physical store it may be worth visiting them and mention the issue.

Check the specs for the model Z1 you have

850 2G / GSM or 3G WCDMA?

If the handset supported 3G 850 then it should see the Spark 3G network fine

GSM Arena seems to support the theory that the phone supports HSDPA 850MHz, so it should work. Try a different Spark sim, or take it back as defective are my suggestions.

Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

Going from the link you posted above, it does support 850 3G.

Also, putting your IMEI into the box on this page also says it'll work just fine on Spark: https://www.spark.co.nz/shop/mobile/whyultramobile/joinultramobile/phonecompatibility.html

Yes I got the same results....looks like an issue with the handset itself. I'll send it back to the supplier for replacement.

Maybe they have sent you the model that does not support 3G 850Mhz

So...update, sent it back to the supplier in Auckland who tested it with their Spark Simcards and says it goes fine. They suggested it might be that I live in Te Anau and Spark's network might be weaker. Ummmm. Seems to work okay right now on my other Spark phone and everyone else in Te Anau seems okay. Thoughts?
