How to unlock Lumia 820 from AT&T?

[Charkatak]

Hi I use T-Mobile USA as my cell phone company. Recently I was able to get a hold of Lumia 820 that is locked to AT&T. T-Mobile for example always unlocked my phones if they are locked to T-Mobile, but looks like AT&T is a different story. I have even unlocked my Android phones through rooting and so on. I have searched some paid unlocking sites, although they do have Lumia 820 listed, but AT&T is missing in the list of carriers. Is there a way to somehow get/extract the sim unlock # from the phone?

A customer in good standing with AT&T USA, can try calling customer service and ask them to SIM unlock the phone so that you can use your own SIM card while travelling to Europe. They may do this or they may try to sell a discounted Europe travel plan that uses your existing SIM card. If you don't get the answer you like, call back on a different day.

Good luck with any other tactic until Q2 2013.

Thanks for the info! I never had AT&T and with T-Mobile it is easy, just like you suggested about calling AT&T. So you are saying that while the phone is exclusive to AT&T for 6 months, then I won't be able to unlock it for the time being?

I called AT&T USA today and asked them about unlocking the Nokia 820.

I told them I was travelling to Europe on business and wanted to be able to buy an local SIM at the destination airport upon my arrival rather than pay for an international plan on the AT&T SIM. The rep said OK, checked a few things and told me that my phone was already unlocked and that I need not enter a code to unlock it.

I asked if I could test this out by popping in a T-Mobile SIM tomorrow just to confirm and he said it should work no problem.

I don't have a T-mobile SIM to try. Can someone please try one in their phone purchased and activated on the AT&T network? Can someone please call AT&T with the same line about travelling to Europe as above and see if you get the same info from the customer rep?

I wonder if folks trying the get their USA-sourced phones online outside of the USA first need to activate the phone on a USA carrier. Maybe it does some magic over the air.

I'm in Argentina, bought the phone full price a couple weeks ago. Two days ago tried with a different sim and the phone asked for unlock code :-S

If you need for example, T-Mobile sim card, then just ask them. It can be deactivated or brand new sim card that doesn't have service. If you phone is locked it will show you the box to type in the code. If unlocked you shouldn't get that.

I bought broken Lumia 820 from Ebay. Repaired it but after inserting my sim I got "locked" message. Can´t get the unlock code from AT&T also as I am not their current or previous client. Also I live in Europe. Seller was not able to get the unlock code also ( electronic shop)...
Tried to make FW upgrade but no go.

Any help ?
Unlocking via PUK code?

PUK codes are for sim cards, won't help with the device. When a non ATT sim is inserted it should ask for an unlock code. You'll have to purchase one online. If it does not ask for a code and just states the device it's locked that means the incorrect code has been input too many times. At that point there's nothing that can be done.

Have you all try to flash your lumia with other firmware?

I think flash your lumia to other firmware can unlock your lumia,

 

[MontyMontie]

If it were that easy would it already have been done? Has anyone tried flashing?

I think your phone is flashed by your carrier, they was modifying the firmware, so it locked and you can't use another SIM Card

So I say again to try flash your phone with another firmware, try global version like APAC, etc, . . download your firmware and flash it with Nokia Care Suite, if you want back to your stock firmware just use Nokia Software Updater for Retail and it will select, download, and flash it automatically with your stock firmware
hope it work

no, unlock the locked phone is not easy like that
you don't need (can't) to flash the global fw
all you need is the code to unlock from locked carrier to make it accept other carrier (for me is AT&T)
the unlocker code is differnce on every phone
here is my unlocked AT&T 820 running on Viettel (Vienamese carrier)
