[Q] Probme with sim unlocking HTC S620/Dash

Hi there.
I have a problem with sim unlocking my phone. T-Mobile already gave me my unlock code.
I entered it once, and it told me wrong code. I don't know if I typed the wrong code or if they sent me one. I swear i only did it once.
Anyway, my problem right now is that when I insert a new sim card, it does not prompt me for an unlock code.
My sim card is unaccessible plus I don't have any signal.
I already have done a hard reset twice, and still not prompt.
Can anyone help me how to make the phone prompt for the sim unlock code?

did u buy it off someone?

Nope. My service provider, T-Mobile gave it to me.
I also have flashed to the phone to the latest ROM here. Still no go...

You need to flash to a 6.0 or 6.1 rom so you can get the sim unlock message. If you flashed a 6.5 rom this will not happen.
This is something that is on the sticky. On that note, thread closed.

but everytime i call out that lady speaks!
i have a SE xperia arc LT15I can anyone help me please?

You posted a link to the unlocking process of the bootloader which has nothing to do with a simlock...as i had some problems with a simlock message appering after installing FreeXperia on mit Xperia Pro i searched the Forums this is something lowlevel and you can't do anything about it aside from get an unlock code when you really have simlock...but since you can actually make a phone call and get a message from your provider i think you should contact them

Bootloader unlocking and SIM unlocking are two separate things.
If you phone was SIM/network unlocked, it is ONCE and PERMANENT. It will not relock.
Contact your carrier.

ok im not going to start other thread now im getting this error
"Your SIM card does not allow a connection to this network"
i tried other sim cards too. but i read here http://forum.xda-developers.com/showthread.php?t=1252019 at post #2
2. Write a Working TA backup from another phone (same model)
3. Restore Security Units.
Thats all, now your phone should boot well but is 90% possible that you dont get Signal so for fix that we need to unlocking.
If this last thing is needed you can refer to this thread:

[Problem] No signal/sim card inserted error after unlock!

Hey guys, i have a complicated issue with my newly brought Galaxy Nexus SC-04D, here we go:
1. I got it on 4.0.1, so upgraded to 4.0.4 and rooted and installed ****docomo v3.1.
2. It said phone is locked, selected unlock, phone rebooted twice then FC.
3. Reinstalled and opened it, showed phone is unlocked, congratulations.
4. Put in my sim card, phone shows no sim card inserted.
5. IMEI is the correct one, not generic.
6. When i put my Sim card before unlocking it never asked me to put in a code to unlock it.
7. Tried to restore it to 4.0.4 using Odin still no hope.
8. Tried the theory of unlocking it, still no hope.
9. Sim card slot is functioning because when i search for networks, it finds them.
10. ****docomo still shows phone is unlocked, tried locking and unlocking, still no hope.
I know the issue is not familiar, searched for hours but couldn't find any answer...
Any ideas how to get it to work would be very appreciated
Update: Doubted if the IMEI is blocked, but it's not, if this might help..

Noticed this strange network activity!! http://www.youtube.com/watch?v=DnHsB8ya-H4

What were the terms of you buying it? Used? I.e. why was the seller parting with it? Did you read through both the fdocomo.apk thread and permunlock thread? You're best help would be there. I know I looked at them at one time, and the permunlock thread was referencing an earlier version of fdocomo..

It was used yes, and i looked at Fdocomo & permunlock thread of course but still can't get any signal, not even for once!!

How to unlock LG-VS870 4G LTE by Verizon

Hello XDA community,
I have Verizon's LG-VS870 4G LTE smartphone [http://www.lg.com/us/cell-phones/lg-VS870-lucid2]. Now I'm in Canada and would like to use this phone instead of buying a new one, therefore I was told to unlock it. Apparently it's legal to unlock your phone now: http://lifehacker.com/you-can-now-legally-unlock-your-cellphone-heres-what-i-1614787933
So I searched online for how to unlock my LG phone. Found many results that tell me the first half of the steps. Found a couple of threads here too about it, but no concrete solution. Some people said this phone isn't going to work on GSM after you unlock it, but I found this patch thread here that says otherwise: http://forum.xda-developers.com/showthread.php?t=2394689
I have the original Verizon SIM card with me too.
Won't ya kindly help a bloke out and tell him how to get the unlock code for his LG-VS870?

So, I tried to root it and was successful with Framaroot. Then Installed Clockwork. Then attempted to install the above mentioned patch using Clockworks recovery mode, but it didn't appear to fix the GSM lock. Whenever I insert my SIM card I get an icon that looks like a SIM card with a question mark inside a red circle at the top right. And when I try to dial a number, any number, I get some chineese lady saying something.
Any idea what does that mean?
I just unbricked/unrooted my phone back to 711A firmware and 4.1.2 Android as it was all the way from the beginning.

Here's the vocaroo recording of the chinese lady(WARNING! TURN DOWN YOUR VOLUME FIRST!): vocaroo.com/i/s0C5ObqOLK6Y

Is the phone unlocked or locked?

I am buying a Samsung Galaxy note 2 from craigslist. The post said the phone was locked to telus/koodo and so I messaged them saying that my simcard is from fido and would like to buy it than
unlock it so I could use it. He messaged saying he tried Rogers/bell and it wouldn't work and he doubted it would work with fido ( I don't know if he knows what he is talking about
because the post said it was locked ) and so I asked him if it was unlocked already or was it just locked to telus and koodo because I heard you could put a koodo sim card in a
Telus phone. He also said maybe the sim card reader is broken, but I thought if the sim card reader was broken it wouldn't be able to read any sim card at all not even telus sim card that it's supposedly
locked to. The phone is model SGH-I317M. I really want to buy this phone and it was the best one I found on craigslist. I am thinking of going to test if it is unlocked but how do I tell? Will a message pop
up when I put in my fido sim card in and boot it up saying "phone is locked, put in unlock code" ? :crying:

Yes a message will pop up asking you for the sim unlock code if it's locked. If it's not locked then you'll get signal. You also need to ask them what firmware is on the phone, cuz you can possibly unlock it from the hidden menu. Just search Xda for that.
Good luck on your new device ?
