[Q] Internet Sharing on unlocked ATT Lumia 900

It may be too soon to ask but what the heck..
I've bought the ATT Lumia 900 and am waiting for it to arrive. I plan to unlock it to use on Telus Mobility in Toronto, Canada. I currently use the ATT Titan unlocked on Telus and sadly Internet Sharing is locked still ATT. Kinda silly considering I'm not even on ATT.
Wondering if anyone can report if it's unlocked on the ATT Lumia 900 once carrier unlocked..

Internet Sharing
I'm with you pistol44, I need to have internet sharing unlocked! Please, if anyone has any solutions to unlock this, post it here so other developers/people can view it. I might go back to my Samsung Focus if this is not unlocked soon.

We may need to wait for Tango in hopes to debrand it. When you "force" an update to the phone it actually debrands it unlocking this feature. It worked for me on an old T-Mobile HD7.

I really hope that forcing tango will do it! Just got my 900 shipped from US arrived today in UK such a great phone, need tethering unlocked though :/

Nope am using my trusty Lumia 800 still, am waiting for the unlock code, but have been told it could take a while :/
With the tango build for the 710 surfacing, might not have to wait too long before a flash could be attempted on the 900!

I generally use Blackberry and Android phones (work/play) so please excuse my ignorance, but I recently came across a pretty cheap Lumia that doesn't want to cooperate with me at all.
I'm unable to update it without errors, and so I'm wondering what you're all referring to when it comes to flashing WP7. I know how to do all this with Android/BB, but have no clue how to completely nuke this phone and start from scratch.. Is this even possible with it so locked down and if so, does anyone have any advice?

That's a strollen phone from store. That's why it is so cheap.
The only way to override it sto find a factory firmware and flash it yourself. There is NO way you can use normal Zune update to recover from this.

I have a developer unlock (I ponied up the $99 to join the developer program). If I register the 900 as a developer phone, and then change the carrier, is that all that is needed to unlock internet sharing?

No. As I understand it, there is no way around this unless you flash to a non-AT&T firmware to replace the internet sharing software with the generic non-carrier version. Dev unlock only allows you to side load apps. That's about it.

That makes sense but it was the place itself that sold it.. A ma & pa type shop. guess they knew it was loaded w/ all the crap. If they couldn't get it off I doubt I'll be able to tho..
How do I flash firmware without zune? Or is it too difficult? Should I just go try & get my money back

First you will have to find a copy of the firmware from somewhere. Then you need find some Nokia utility to flash it to your phone. Each manufacturer has their own method. Who know if it its easy or difficult. Good luck.

its not that difficult actually. search for a software called Navifirm , it should allow you to download firmware for any Nokia phone and you will find all the firmwares for the lumia 800 by network provider. then you need to search for Nokia Care Suite (the latest version you can find). that will allow you to flash the phone.
both softwares can be found on the web.
good luck.

i have to tried to flash the Rogers firmware on the AT&T Lumia but i get an error that the signature file of the firmware is not valid.
i have been able to flash any firmware on the Lumia 800 but it seems they changed something with the 900.
that's really the only option. but right now only the AT&T and Rogers firmwares are available for download. I suppose as soon as the Lumia gets released to other markets, other firmwares will show up. a european or australian should resolve the problem as they are usually very close to stock.

Hi Pistol - I just used this site:
http://www.remotecellunlock.com
For Rogers Nokia Lumia 900 unlock code was $8.79 !
Now lest's hope they can actually send a code in decent time. I have used them before for other phones and they were quite quick.

Wow.... unlock code received ! 35 minutes ! Punching it in now. Seems to have unlocked the phone, but I don't get a signal.
Could it be my Mobilicity SIM is not compatible ? Or maybe something else? Thoughts.... ideas ?

Well as far as I know the Lumia 900 is not compatible on Mobilicity/Wind as they operate on different bands than Telus/Rogers/Bell/ATT. That's my first guess. Unless it's quad band like the Lumia 710 from Rogers but I haven't heard of that.
But thanks for the website referral!

funny, it won't let me buy an unlock code from that website. Doesn't give me the option to fill out a payment form

Cellphoneunlock.net
First time using Cellphoneunlock.net
Ordered my code on April 9th (Launch day, yesterday, after I bought the phone) at around 3 P.M.
Waited a day and a couple hours before I called them to see whats up.
I called and they said I should get it in about 5 business days.
So now it's a waiting game. It seriously sucks having to look at this phone and not being able to use it.
P.S. I called At&t before using Cellphoneunlock.net to take a shot at getting a free code. They were willing to help me. Took my IMEI number and all, then put me on hold. Came back saying exactly this: "At&t is in a contract with Windows Phone which prevents us from unlocking their devices. Ever."
Try it. Maybe your carrier will go through with it. You never know. You'll have to wait until you actually have the phone though.

I called ATT today and they said that they don't have the unlock codes for the phone yet (which is probably bs)

It is complete B.S.
They just don't want new flagship phones being used on other networks.

Hmm..
I had similar issues unlocking my Titan as I got it right or just days before release. It took me a few days to get the unlock code as well. I recall the unlocking website saying the codes weren't available yet. I called ATT who said they couldn't help me. Then about 4 days later the unlocked emailed me saying he had new codes and wanted to try again and we unlocked it.
This may be a situation where we need to wait about a week for the codes to be released.

Yes... it was looking promising as the bands on the Rogers Lumia 900 are the same as the Rogers Lumia 710. In fact the Lumia 900 actually has 900 listed under WCDMA/HSPA bands. Unless the label is wrong? See pic of the Lumia 900 I just bought from Rogers.....

You need to make sure that like the Lumia 710 it supports 850/900/1700/1900/2100MHz. The 1700MHz specifically for Wind/Mobilicity. Rule of thumb is usually anything on T-Mobile works with Wind/Mobilicity, ATT is everything else.
EDIT: Just saw attached pic, didn't work for me when trying to view till now. Interesting.. Not sure in this case. Only thoughts are being LTE perhaps you require a different sum. Telus requires a newer sim than my existing one in my Titan to work on LTE. Otherwise I'm stumped.

Now that you mentioned it, when I called the Cellphoneunlock.net, the guy that I spoke to said that the Lumia's take quite some time to generate codes for. I just realized that the phone is not even 3 days old yet. So how has he unlocked it before?
I have a strong feeling I will be receiving a refund.

Yeah it's very possible.. I had a few refunds before I got my Titan code. I also had trouble unlocking a friends Lumia 710. Got a refund for no return code and I emailed asking why and he said there's no code and there never will be for the phone. But before I had my friend return their phone I tried a different unlocked site and got the code within an hour.

Yes ... I'm thinking the SIM is old? Or in fact the phone is LTE in those bands, but the label is stating different.

For my Titan I believe it was mobileincanada.
Sadly I couldn't find the receipt for the other site so I can't recall that one. What I do recall was that it allowed you to input your IMEI # before submitting and it confirmed if they actually had the code first so you're not wasting time or money to get a refund with no code.

Oh well. Got my fingers crossed for a return code from Cellphoneunlock.net

woah .. did some one beat me ? i thought i was the first one to get this in GTA . i got this on Monday at 10:45AM lol ..
Now can everyone see the voicemail icon working ? for me its not .. just missed call and a txt saying there is voicemail ..

Nissan350, please keep us posted on the unlock code.
As for trueblog's issue.. Not sure. I know on Wind they would text me everytime I had a vmail. That was an exclusive yet annoying feature with Wind. On Telus I don't get those texts.

Hi Nissan 350 any updates on your unlock code??
I found someone on ebay selling unlocked lumia 900; (i cant post url here but you can easily find it by searching keywords lumia 900 cyan unlocked) I sent the seller a msg and asked him if the device in a lumia 900 at&t device and also asked about the method used for unlocking? he replied back saying that it's actually an at&t lumia 900 and he did a developer unlock? I replied back asking for details; I'll post again when I get it... but if this is true it gives hope that the lumia 900 can be unlocked...

Buying a used Lumia 900 for use as PDA.

I personally do not have a cell phone, only an iPod Touch. However, I am interested in possibly getting a Lumia 900 used off eBay for purposes of using it as a WiFi-only PDA device. Plus, the Lumia 900 has one thing my iPod Touch doesn't have: GPS and turn by turn directions with offline maps. That, and a better camera.
One question, though:
Are all software and firmware upgrades handled by Microsoft/Nokia?

Yes, sort of. All software updates (OS and Firmware) are pushed by Microsoft through the Zune desktop software. But they have to be approved by whatever carrier is locked to the phone. If it's a carrier unlocked phone, then one less approval in the process.
With that said, there is more than one way to get needed update to your phone if you don't have the patience to wait for a carrier. My Surround (SIM free) does everything my Lumia can do except make cellular phone calls and send/receive texts.

Can you provide a picture of the email they sent with the unlocked device? Can blur out the code if you want. Just before everyone rushes there.

And Here we go again...

I mean people have unlocked at&t Lumia 900s. At least they posted pictures of them running on other networks but no I don't think the OP with only 2 posts is the person that found a reliable third party to unlock the at&t Lumia 900. It's possible... but highly unlikely. I will wait for pictures.

I've found in the past if you are on contract and have your phone for a reasonable amount of time (8 months) they will unlock it for you if you have a reason (traveling overseas). To be honest I've only done it once and they didn't give me any hassle.

8 months seems long, it's only 90 days on T-Mobile. I'd guess they are around the same timeframe, unless it's an iPhone they may be more strict.

Thank you for your attention friends.
I realize that in fact, there are no certainties. just guesses, and frustrations can occur in October, note that there is nothing official and I've noticed AT&T based on Iphones, they do what they want. Soon will launch Windows Phone with Windows 8 and if AT&T follow only what they say, that the devices will only be eligible for unlock only when the contracts are fulfilled, only in 2 years, the Lumias 900 there will have become weights of paper.

At&t is 90 days as well. Must be post paid and account in good standing.

Lumia 900 ATT unlocked!
Hello! I've followed for a long time the thread named "Recommended website to unlock Lumia 900 (AT&T)" and I've tried also some of these websites without any luck until TODAY \o/
I've used Unlock Liberty and passed my order on july the 29th and I was about to call and ask a refund but after talking to one of the guy working on Unlock Liberty, he told me that some code may take up to 4 weeks to get it. Well it took more than that obvisouly but I fanilly got it.
I got the Lumia 900 from my parents when they were visiting LOs Angeles ( I live in France, but one of my brother lives in Los Angeles and have an att account, that's how I could get one). I didn't at first I wasn't able to unlock it, it's after visiting this forum and reading the thread above that I realised I may be scr*wed.
I even tried 3 days ago to call AT&T and explaining my case (present from my parents, and not beeing able to use it in France with my current carrier), she asked my my IMEI number and told me that her computer was saying that there is no unlock code for this phone yet, they will be released October the 10th, so she said the best I could do right now is to wait for this date and call again then!
Well, I'm glad I don't have to wait that long anymore
I know it's my first post here so you might think I am not trustworthy (plus I am french so my english is not perfect so sorry for the mistakes), but I am posting a picture of my unlocked ATT Lumia 900 and I can even take other pictures and post them as well if you want me to show you that it is not a picture I've taken from another website

Thank you for using Unlock Liberty.
We will appreciate it if you leave us feedback comment on our testimonials page.
What I found weird was that they gave me 4 eight digits code... i've only used the first one of the 4 they gave me and it worked immediately, I didn't had to enter the other 3 eight digits code...
Anyway, since October the 10th is coming quite soon now, I don't think it is usefull to use one of this site anymore, since it is taking very long to get the code (or maybe they have some now, so it might go faster).
Well, maybe the thread saying that ALL these websites are scam etc should be corrected Plus it's full of false informations (stuff like ATT has no intention to give unlock code ever...).
If you have any questions, I'll be glad to answer them
Good luck!

How much did you pay for the unlock code?

any way to change the branding on a Lumia 900

Is there any way to change the carrier branding in WP 7 on the lumia 900. I understand you can do it for other devices like LG so I was wondering if I could do it for the 900? I want it to point to Tmobile instead of ATT

Not too sure if T-Mo had the 900 on their Network so not sure a T-Mo ROM exisits, What you could do is find out the code on the sim tray and find a relevant Stock ROM on Navifirm and flash using Nokia Care suite, This will NOT Unlock the phone however but just rebrand it with stock generic firmware.
Code on the sim tray should be similar to 059P6N9 etc, There are a few threads on XDA explaining in detail on how to flash a New ROM using Navifirm and Nokia Care suite, Good luck.

I got it sorted out enough to allow for my wife to use the store without issues. I am not sure you can use a stock rom on a ATT 900 due to inclusion of LTE radio...
Thanks for the help
