hi giuys like the header says i would like to sim lock my phone... what i mean is that i want my phone to work only with my sim... i've tried to search on the forum for it but with no results... can you help me???
thanks in advance
hi. first of all, if your phone is sim locked, it not gonna work only with your sim but with every sim card of your network ( vodafone in your case); secondly i've never heard about something or somehow to sim-lock again a phone!!! ask Olinex, may be he knows!!! good luck
i didn't mean the general sim-lock like the branded phones have i mean maybe a lite app that runs when you start the phone and blocks you from using the phone if there is no sim or it isn'tt the sim you've previously registered...
aahhh okayyyy, you mean something like the nokia's phone locking if the sim is changed! i've understood now! i was looking for it me too but i've never found a bit! we'll stay in touch, if i find something intresting i'll tell you ciao

I got what you need but it is shareware [you have to pay for it].
It is for Wm 5 but i think that it will support higher too.
Did you search on google?
Here is the link: [click].
I searched for the "cra**ed" version but all links are dead or fake.
hi thanks for the reply guys
if you can use password protection why bother such thing!!!
okay, password may be broken by software, but same thing for any kind of security also.
anyway, a program can be written such as:
small memory residence program which will check the sim nr. in every few min.
if not matched, will enter into Airport Mode + screen lock
keep checking every few min.
if it matched the nr. stored before (encrypted) will unlock airport mode+screen
or the program will only trigger at the stratup or sim change
hey, new to the site and new to the wildfire and im already having a few problems.
i just bought mines off my uncle, who always used it on o2-ire without any problems. he never used any uk simcard because he thought the fone was locked.
i tried my simcard and it says "your simcard does not allow connect to this network" or "error while searching for network". as it wouldnt find a network i figured it was locked, so i went and bought an unlock code.
problem is, i cant find where to put it. i turn the fone on with a simcard (ive tried a few on different networks), and it never asks me for the code, yet it still cant find a network.
ive tried my girlfriends mothers o2-ireland and that still works.
just wondering why it works for o2-ireland and not on my o2-uk or vodafone-uk and doesnt ask for the network unlock code.
sorry if this seems jumbled and rambeling, im just trying to explain everything.
thanks in advance for any help.
Get a different carrier similar card. Not the ones you have been using. Put it in and boot the phone, it should come up with a screen telling you to input the code to unlock. Some Sims just don't give you the screen
Try a 3 sim if you can.

crap, everyone i know is o2. ill ask about, ill see if someone has a different sim network, i think my girlfriends sister is vodafone-ireland, i could try that and see. thanks for the fast reply, ill give it a shot
Hello. I've read many threads like this but didn't find a solution for my problem, so I start a new one, my first thread.
I've bought a Note II (N7100) international version months ago and suddenly I got the message "not registered on network", "no sim", can't access to mobile networks and so on. Further, it is impossible to access to settings>more settings>mobile networks> "INSERT SIM CARD TO ACCESS NETWORK SERVICES". For a better knowledge I found a video on youtube it explains the exact issue I'm suffering.
I got this error when I was on stock rom, so in order to fix it, I thought it was the modem, so I rooted it, installed the criskelo rom v.17 and v 18 and didn't worked. Then I installed the file "modem.tar.md5" and no results. When I try to flash that file trough odin I got a message "removed" and then the phone reboot before the "pass" message.
I have tried my sim card on a S3 and it works, have tried the s3 sim card on my note 2 and it works too. It is like my phone does not match my own sim. When I went to the carrier they tried another sim and it works on my device. I have bought a new sim card and it DOES NOT WORK. I think it's a software issue because the phone worked with other sim cards. It is quite frustrating 'cause I have this issue for about 5 months and no solution come to me. I'm consider the hammer test for my Note II if I don't fix it during this month. Can't sell it, rent, borrow or give away because the phone DOESN'T WORK AS A PHONE.
Please, some kind soul, HELP ME!!!
Sounds like a hardware issue with the SIM card reader in your phone, not making a good contact with the first SIM.
Can't you just get the first SIM replaced?
Indeed, I thought it was the sim reader so I changed it, didnt worked. As I said the phone read some sim cards so I think its not a hardware issue. Please check the vídeo I left. Thank you for your response.

the SIM it's new, got it 2 weeks ago with another new phone i bought from metropcs, but do you know what that error means or something ? because i've seen different ones, like MM#6 & MM#4
Is the phone blacklisted?
Not a clue on the error. Never seen anyone else report one like that before.
the phone it's not blacklisted, everything it's clean

I'm in Canada and I use this website to check for black lists: http://www.protectyourdata.ca/check-the-status-of-your-device-in-canada/
If you want, could input your imei as another check.
I see Metro PCS uses AWS bands which the i747 and i747m does not natively support (http://www.tech-recipes.com/rx/1498...-network-frequencies-and-phone-compatibility/).
Yeah.wanna to unlock your phone try galaxsim unlock apk from play store.

GalaxSim Unlock is*. Even with recent ICS or JB roms update, your GS2, GS3, GS4 or Note2 won’t relock after reboot.

Hello there, this is my first post here, I searched all the forum but could not find any solution to this.
I have a Optimus G E987. Unrooted, unflashed, with original rom, didn't do anything to the phone yet as I recently got it from a friend.
My friend was under a different carrier that I am. Since his contract had expired I was free to contact his carrier and get the unlock code to unlock my phone by IMEI. After succesfully unlocking the phone, I inserted my old sim card, it was a Standard Sim so I had to trim it to fit on the Micro Sim slot the Optimus G has.
Everything worked beautifully until I started having signal issues, both data and phone.
It does not happen everywhere, but it definetly happens at places I had perfect signal with my old device like my work place. To solve it, most times I can go to the network settings of the phone and choose the auto select option. This restores the service but I lose it again in a few minutes. Sometimes this does not fix a thing and I can not recover service at all.
I know its not a hardware issue as my friend had no signal problems whatsoever. Maybe I need to set up something in my phone to get it to work properly but I am completely clueless. I suspect it may be the sim card as well.
Any help will be greatly appreciated.
