Hi,

I have a Motorola Defy+ with the specs:

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 2100 or HSDPA 850 / 1900

And I am on Vodafone NZ...

On start up, with mobile data off, everything is fine with calls and sms.

If I try and turn on data connection over mobile network, the signal strength remains but there is no data connection, nor infact any mobile connection (calls/messages cannot send), despite the 'signal' being ok (signal strength -83dB 15asu). I have to restart to get "working" mobile reception back.

Also if I set it to use only 2G networks, same problem.

I am thinking it is perhaps the bandband or whatnot is incorrect...

Looking at this: http://www.geekzone.co.nz/forums.asp?forumid=85&topicid=78215 specifically the last post "You can go to XDA and download the baseband of Defy to swith between 850-2100 or 900-2100" -- the phone has a bandband switcher on it...

When it boots and is working, mobile network type is, according to phone status, UMTS.

But I don't know what settings I should choose for Vodafone NZ.

Any ideas / advice most appreciated.

Thanks
Rob

Hi, I will have to do some checking about as to if the Defy+ supports both 850 and 900 UMTS something makes me think it may, but dont be surprised if thats one issue. Other is, the APN, you will get no data through if the APN is not set correctly, check below.

Just looking through that thread, I think the reference to the baseband switch refered to selecting the correct setup for the particular hardware you have. So if your hardware supports 850 or 900 you must select the correct baseband firmware to correspond.

So I guess the question is, where did you get your Defy and either what network was it destined for or what RF hardware does it have, 850 or 900 UMTS.

Hi,

It was imported from the UK, under the "Vodafone/2Degrees" suitable, so presume 900... is there anyway to check the hardware?

Cheers

So again have you checked the APN settings as that sounds to be a potential issue.

Yes, APNs are correct.

If it turn on / enable data over mobile network, no data connection is made, and I loose the ability to call /sms.

Odd...

Having reflashed the phone it's working fine now, so is not a hardware issue with the VF NZ network.

I figure a setting somewhere I made in the ROM sent it down a bad path...

seems fine now, so far...

Hi again,

Contrary to previous post, all is not fine again...

And I have since discovered that they have indeed send me a WCDMA 850/2100 device instead of the 900/2100 they promised me and convinced me I had... It wasn't until I got the packaging out of the bin and read the side...!

So, am I right in concluding that the fact WCMDA hardware in the device is 850/2100, 3G will not work (and cause these connection drops)?

I'm in the outskirts of Tauranga, which I think varies between 3G (2100) and 3G extended (900), so that would explain the 'sometimes working' -- i presume it would be working when I can get 3g (2100) but then fail miserably when moving to 3GExtended...

So, just before I go and shout at the people who sold me the device, is all the above sounding right and the most probably cause of my issues?

Thanks for your help, appreciate it!
Rob

Hi, yes what you say is correct as per our previous posts. You could port to XT but that may obvioulsy not suit you.

Cheers
