I have a Lumia 900 and when i try to use internet sharing its telling me to contact AT&T to add it to my plan. I live in New Zealand which will mean I cant add it to my AT&T plan since they don't exist here.

Is there anyway for me to unlock it? Ive seen a mention of 1 person who called them up and got a code but I dont know if it is possible. Would explaining my situation likely result in that or are they just going to tell me im stuck with it because im in a different country?

I know its a long shot but is there any other way to access it? It's a feature I really want from a phone.

no you are screwed.

by chance did you download the Nokia Network Setup app?

[Andrew Allman]

It appears my brother did (he has a 800 and downloaded a bunch of apps that he said are good to have). So that means a call to AT&T wont do anything either?

if you got any solution for this please let me know, i have the same problem here in Egypt and i called at&t and i got nothing :(

There are other threads on this forum which indicate that flashing the TelCel Mexican LTE variant ROM will result in a working Internet Sharing function, with no bloatware, refer the posts by tomcahill. I have read reports on these threads about some people successfully flashing ATT devices (with working LTE), while others have not, so YMMV.

ive got a Rogers Lumia 900 rm-808 ( i know its not AT&T ) but you can try , internet sharing didnt worked either ( i use my phone on Fido network) ,
1.i called my carrier to activate internet sharing in my carrier account (no cost )
2. go to your phone: Settings , About , reset your phone ( it will erase everything on it ) and thats it! now it works even without network setup app!

windowsphone must store settings from simcard on first time use, and keeps em! so you need to do a reset!

well based on that thought one could throw in a SIM from a fully activated ATT account with sharing then pop in say a ST SIM that doesn't allow sharing but that is certainly NOT the case!

Had to pull this thread back up. After todays update that got pushed through Zune my ATT unlocked 900 is able to access internet sharing on T-Mobile!!!
OS version: 7.10.8862.144
Firmware: 2175.2307.8862.13100
hardware: 112.1914.2.0

But do you have MMS working? I'm wondering why the .144 update is still rolling out, since I got all excited there might be a newer update coming..but sadly I already had the .144 and still having trouble getting both MMS and internet sharing working simultaneously.

Yes, MMS still working

It's not just about the .144 OS version, but also the firmware that comes with it.

It's also about the .13100 revision of the firmware that has now been made available via Zune, which does make a difference. That's something you wouldn't get through earlier methods such as 78er.
