Help Unlocked HTC Desire HD

[jflong23]

I have a HTC DHD that was locked to the Telus network, I went through an online company to get it unlocked. They gave me the unlock code and now I am using the phone with a Rogers SIM card.

I am assuming the phone is unlocked because I can use the Rogers SIM card and the available networks I can see are Rogers, Bell and Telus.

I want to switch my network provider to either Virgin, Koodo, or Fido etc. I have been to each store to try there SIM card and my phone doesn't recognize the 3 Networks.

Is my phone really unlocked?
Is there a way to reverse the unlock?
Is there a function that I have to change on the phone before the other networks work?

Thanks,

I'm not familiar with those networks, but if it really is unlocked, it should work with any of those.

When you say it didn't work, did the phone load and you couldn't make calls or did you get any error messages before you logged on?

When I try to put in a different network SIM card (Virgin, Koodo), the phone does not pick up that network. On the top right corner it shows the "No Signal" Icon.

When I go to "Wireless and Networks" and to "Mobile Networks" and to "Network Operators" and then "Search Networks" it only shows 3 available networks:

Rogers
Bell
Telus

Sometimes when you do a search you get 0 networks.

If it is unlock shouldn't it show all networks like Virgin or Koodo.

I would've presumed unlocked, meant unlocked.

If you change it to automatic, does it pick up the new networks SIM?

 

[jflong23]

No, if change it to automatic, it does not pick up the new networks SIM. It says it is unable to connect to this network at this time.

I don't know what to do.

I'd hazard a guess and say it's not really unlocked then, sorry.

 

[jflong23]

Is there a way to reverse the unlock and re-enter another unlock code?

 

[El Presidente]

Not to my knowledge unfortunately, sorry.

You can fully unlock by rooting etc, but I don't know if that's a feasible option for you?

 

[jflong23]

How do you root the phone and what does it do to the phone?

Xyro does a pretty good job of explaining the benefits and detailing the risks involved here: http://androidforums.com/desire-hd-all-things-root/400056-rooting-dhd-worth.html#post3106892

Could it be that the phone just isn't capable of picking those networks up? Take a look at Koodo, it lists the frequency used as HSPA on 1900, yet from the DHD Spec page, it can only pick up HSPA on the 900 & 2100 frequencies.

I could be totally wrong. It might be worth giving HTC a call to see if it's compatible with those other networks.
