Does anyone know if you get any kind of signal with Verizon sim card in? I only need it to be able to send otp and unlock the bootloader so I don't need strong signal.

How can I tell if my SIM is unlocked?

I am S-off and Rooted. How can I tell if my SIM is unlocked? I will be traveling to Amsterdam this week and want to verify that my phone is ready. Do I still have to call Verizon for an unlock code?
Thanks!

Moved to proper forum.
I am not sure if the s-off and root alone are enough to unlock the phone. I had to call verizon to unlock my phone. It was a very simple call to verizon global department. The regular call assistants are useless so make sure you get transfered to the global department.
you must have either used an xtc clip or called Verizon to be sim unlocked.

To check if the phone is SIM locked, do the following:
Secuity==>SIM Lock==> if there is a cell to enter unlock code then the phone is SIM locked, otherwise the message will be "The SIM lock Disabled" Good luck.
I am not sure about this but i do not think that is true for some phones because if you root and unlock it with some of the procedures here for some phones it still will do that but your sim is unlocked in the actual hardware and not a software unlock someone correct me if im wrong.

Ive recently unlocked gsm , but can't change to GSM mode ( always show CDMA mode)
change to GSM mode , Incredible 2 show
"there is no Sim Card on your device . Your device will switch to CDMA mode now"
try another Sim card , change to GSM mode ,still show ""there is no Sim Card on your device . Your device will switch to CDMA mode now""
My incredible 2 , new in a box 100%
Unlocked by code
Solution ??? help
In order to switch to GSM you have to have an activated SIM card in place from a local provider (AT&T or T-Mobile); otherwise, the phone will not stay in the GSM mode and will default into CDMA.

[Q] SIM-Unlock without foreign SIM

I am sending my phone to my friend in Ireland, and I wanted to put CM10 on it and unlock it before I send it to him. I need to unlock it now before I send it. Is there any way I can unlock it without a foreign sim card? (btw, I have an unlock code)
Edit: Never mind, I managed to use the micro-sim out of my ipad.

[Q] How to verify a working sim slot on LS980 phone?

I get a used LS980 and It havn't activated with Sprint yet. No Unlocked yet. No Sprint sim card handy. Normally, it show NO Sim card on the phone, but when T-mobile or ATT sim card inseted, it still shows "NO SIM Card" I remove the sim card completely, and reboot the phone and insert Sim again. It still show No sim Card?
Don't they support to show invalid Sim Card if insert ATT or Tmobile sim card in a locked Sprint LS980 phone? I have a Sprint Samsung Galaxy locked with Sprint, If sim card inserted, it show invalid. Same with Verizon locked phone show invalid sim if ATT or Tmobile inserted.
Now, it seem likes a defective sim slot on the phone. without activated or a Sprint sim, how to verify it. Please be advice?
inserting any sim besides sprint will show no sim card message

yup.. insert any sim beside sprint show No Sim Card message. is it normal for anyone?? or the sim slot defective?
I'm planing to use it on Freedompop. Order a sim from Tint.com could take awhile. While i'm wait for sim arrival, please tell is the sim slot defective or normal?
No one can help? Or test on your LS980 to find if it support to show invalid sim card on your locked LS980?
BTW, This device here still JB 4.2.2 with some of VZ8 firmware. Do I need to unlock for further test?

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 ?

Can a network unlock code screw up your phone if done wrong?

My UK Vodafone 815 only fully works with certain sim cards. I used an unlock code from ebay and have zero issues with O2/GiffGaff sims.
Now I wanted to use a Life Mobile (EE) sim but the data speed won't go beyond E yet the same sim gets H+ in other phones. After the unlock iD Mobile/Three sims wouldn't make calls.
Can the network unlock have gone wrong somehow?
Still struggling with this....let me ask another question.
Is it possible to flash the original vodafone software (assuming I can find one) to re-lock the phone so I can start again with another unlock?
