[Q] Nokia Lumia 810

hello, I wanted to ask if anyone knows any method to unlock lumia 810 (sim unlock)

Depends who it's locked to, but the usual approach is just call up the operator to which your phone is locked (or check their website) and get an unlock code...

Unlocking Nokia Lumia 810 is turning out be a nightmare. Tried bunch of unlocking sites. No luck so far. Only possible solution seems to be asking T-Mobile support to provide it, though highly unlikely as I am not their customer. IMEI is clean, so it wouldn't hurt to try.

Unlock Code for At&t

Has anyone been able to successfully unlock the sim for this phone, I'd like to use it on T-Mobile and At&t wont help me out. I have read into several unlocking sites but wanted to know if there were any that can confirm that WILL unlock the Moto X.

Nokia Luma 520 Network Unlock

Hi all,
I have a Nokia Lumia 520 locked on the orange network. Is there any possible way to get this phone unlocked to use it on any network?
Don't mind if have to flash with new rom etc.
Thanks in advance

Ask the carrier or ask Nokia, or buy an unlock from somebody. To the best of my knowledge there is no pure software/firmware fix right now. These days, there usually isn't; the SIM lock is implemented separately from the rest of the device firmware.

[Q] WP 8.1 dual sim function

hi guys
i saw the review of nokia lumia 630 dual sim (passiv dual sim. only one sender/receiver built in)
plus i saw that my nokia lumia 920 just received an sw update regarding "being able to handle dual sim.." (net+).
=> so i wonder if it would be possible to change any lumia into a dual sim phone by using one of those dual sim adapters.
(of course you can use these adapters since ever but you have to switch between the sims manually)
would that work?

Lumia 640 Unlocking problems

1) AT&T Lumia 640 GoPhone
I get code from at&t but it does not work. I put in my new zealand sim and turn it on and try unlock code on 10 attempts remaining screen and it says incorrect code then puk required, I then input sim puk then it says sim error.
I also try ##7820# method and it accepts code and padlock is opened but on reboot it is locked again.
2) Cricket USA Lumia 640
I paid for unlock code on eBay and it does not work on 10 attempts screen or ##7820# screen.
If anyone could help with either problem or point me to a guide to hack a registry or whatever I would be very grateful.
Thanks.
P.S. what happened to those little black multi -unlock sim things you could buy back in the days that slid in between your sim and the phone and could fool a phone?
Do they not work in this day and age?
Thanks.
