I'm sure this topic has been flogged to death, but I cannot search for a similar answer as every topic that gets locked ends in phrase "locked", and thus it brings up every older thread on Geekzone.

Anyway, I bought a Samsung A411, which was on Telstra's Next G network in Australia. When I put my XT sim in or a Vodafone sim in, it says a message when it starts up of "Incorrect sim, network lock".

So question one is (silly as it may seem), is this phone locked to Telstra's next G network? I'm guessing it is, but want someone with Telstra phone knowledge to confirm thats whats going on.

Question 2 is, the box says 850MHz HSDPA, the Samsung website said nothing regarding the phones frequency, I looked up the IMEI and it said GSM 900/1800/1900MHz (no mention of the 850MHz HSDPA that the box clearly states on it).

So if it is locked, and I go to the effort to get it unlocked, will it work on XT and/or Vodafone?
As in is the 850MHz the phone's frequency period, or is it only for data and GSM 900/1800/1900MHz is for the other phone functions like calls/texts?

Yes, it's locked.

Yes, it will work on XT Network.

Because it's a Telstra handset it may have some customisations that are specific for that network. You will have to change the APN configuration, but some of the firmware things may not be changed. If the firmware for example "calls home" to check with Telstra for updates, or anything else then your account will be charged accordingly for data usage.

Hmmm, I don't like the sound of this "calls home" idea...

I only want to use it for texts and calls not data. But if its likely to do things by itself that may ultimately land me with a large bill, then probably best I ditch it now before it gets me in trouble. Hence why I thought I'd find out if unlocking it was worth the expense. I just wanted it as a cheap work phone, so that if it got trashed I would not be as upset as I would be if it happened to a phone eight times the value.

The person I bought it off seems very vague about it, I think they either genuinely don't understand or just haven't used it on an NZ network since moving over from Australia.

I am not saying it happens to all devices, but it happens. I know someone who complained here on Geekzone about his bill showing data usage - after Vodafone investigations it was found he had a Chinese handset from China Mobile and it was connecting every day to a Chinese server looking for updates.

There you go... Better safe than sorry later.

Just had a thought, if I used it on prepay, there would be no fear of huge bill? Ie if the phone decided to "call home" and I get charged, worse that will happen it prepaid credit is drained, rather than huge end of month contract bill?

Thats just an academic question seen I'm on the subject.

I've contacted the seller for a refund, but they dont understand the situation, so probably will be a difficult process.

I bet you'd be pissed off nonetheless if you see your money going away...

i bought a Nokia which was Telstra branded, I changed the product code after a bit of looking then hit it with generic Nokia software (??) and all is good. It works fine with XT and Vodafone now.


BUT my phone was already unlcoked, so no dramas there.

Can you change the data settings within the phone to false/invalid values so it's unable to connect at all? Obviously calling and SMS would still work.

Does anybody know:

A) How much it costs to get a mobile (Samsung A411) unlocked by Telstra?
and
B) Where else I could buy one to use on XT?

Thx

I changed product code with a Nokia phone and it bricked upon the update sequence, be warned, probably better just buying a local phone. You may be able to set the default "APN" as something invalid to attempt to avoid data charges but it could have an "internal" or "secure" apn which may still override it.
