[Q] Sim Card not working!!!! Sim Network unlock Htc hd2pin????

Hey guys i need help.
i have android 2.2.1 installed on my hd2. it worked perfectly fine with my old simple mobile sim card. now when i changed to another sim card of another company, it doesn't work. it prompts for a sim network unlock pin!!!
wat should i do to unlock the pin????
p.s the new sim is fine and works perfectly with all other phones

You need to phone your old service provider and they will give you the unlock code so you can use different sim cards on your phone .

and dont keep trying till you get an unlock code! you only get so many attempts at entering a pin before the phone locks up for good.

[Q] Simcard not recognized anymore

Hi, I messed up my brandnew D802 LG G2.
I used a Nano Sim before and took a cheap adapter for Micro-Nano-Sim. Unfortunately my nano sim inside the adaptor moved a bit inside the G2 and I couldn´t get both out. I had to pull it with force and now all Simcards are not recognized anymore .
I´m on Stock rom but rooted the phone.
What would you say, should I send it in?
Should I remove root before?
Thanks

Remove the root and send it to service center

[Q] "No Sim" message with a specific sim

Hi,
I got a very strange problem.
When I put my sim inside my Galaxy s4 I get "No sim - please Insert sim" error.
When I put my sim in other devices - Everything works fine.
When I put other sim cards inside my Galaxy S4 - everything works fine.
My sim and my galaxy simply do not get along.
I tried to replace my sim - Didn't help.
I tried to flash my rom and modem - Didn't help.
What can i do?
Anyone has an idea how I can debug it?

LG G2 D802 Sim locked after Rom Flash

Hi all,
I have a LG G2 D802 ( bought it year ago , no provider, installed my old T mobile sim) and i installed a new ROM but after the reboot it was asking my PIN
So i used my PIN that i always use and it denied it. So i tried the original PIN from the SIM Card holder but stil denied. Tried using PUK code and recover the PIN also denied.
No it says SIM LOCKED all the time.. Please help with solving my problem i tried searching on forum and google but its all for network locked phones like T mobile

ok so i installed a other ROM and its working again. So maybe the other ROM was missing files or something for proper network.

[Q] Can't unlock Sim card VS980.

I am traveling in Europe with my lg g2 and bought a Vodafone Sim card. When I put the card in it asks me to put in the PIN which I do and then it tells me that the Sim unlock operation failed.
I have tried both the pin and the super pin and neither work.
I am on AICP 9.0 nightly. I am going to try to flash the stock ROM that I found to see if that helps.
What can I do to use the Sim card?
