1. Go to https://www.att.com/deviceunlock/?#/ , check and confirm at bottom of the page.
2. On next page at Customer Type , tick the "Non-AT&T Mobility customer
" selection , fill in your IMEI , a first/last name , and a email address. ( note: John Smith works fine. I'm sure he has requested a lot of Unlock Codes )
3. Check your email for request confirmation and then wait. In another day or so you might get an initial email saying they are "investigating blah blah blah...".
Wait another day or so and you should receive your Unlock Code or Denied.
4. Unlock Code in hand, boot your phone (no sim installed) , click on Phone icon and click past the "no sim" error message, click on Dialer icon , type in ##7820#
5. Enter your Unlock Code and hit enter. Wait about a minute or so and you should be presented with Unlocked screen.
6. Reboot phone and get back to the Dialer and enter ##7820# to verify Unlocked status.
GSM Worldwide: Yes, this phone will work on supported GSM bands in other countries AFTER you unlock it from AT&T.
I've tested it in Singapore's telco - user TGS
Unbranding (NOTE: TRY AT YOUR OWN RISK):
Follow the instructions on this page: Windows Central
Unbranding removes AT&T's software and reverts the phone to Microsoft's ROM.
You get updates from Microsoft instead of AT&T.
MS's rom appears to run smoother than AT&T's.
Alternate deal -- Lumia 640 @ $46.99
The MSRP of the AT&T Lumia 640 is now $59.99, and it's not the $30 & $40 Black Friday prices we've seen, but at an extra $20 over the 635, it's an upsell worth considering . Main benefits -- Larger higher-res screen, double the system memory, higher-res camera with a larger sensor, larger battery. The Lumia 635 is also missing a few basics that the 640 has -- LED flash, front-facing camera, and ambient light sensor. Perhaps most egregiously, the 635 is missing a proximity sensor. It uses other sensors, including detecting your face touching the screen, to detect when to turn off the screen when taking a call. You can also press the power/lock button to turn off the screen when taking a call. The 640 has a proximity sensor. (Sorry to editorialize in the wiki -- I still gave this deal a thumbs-up.)
