[Q] How to Unlock Sim Card? - XPERIA X10 Q&A, Help & Troubleshooting

Hey guys, I'm leaving the country for a bit and want to bring my x10 for the camera / wifi. If I leave my sim card in there I will get charged for roaming.... Just wondering if anyone knows where a guide is to make it so I can use the phone without my sim card in it so I can just use the wifi and camera.
I look around a bit but the ones I found were for different phones =/
Thanks Guys

You can just disable roaming in settings.
Settings »» wireless & network »» mobile network »» then disable data traffic and roaming etc and you should be fine

You can use your phone fine without a SIM card in it aswell. Just take it out and turn on your phone.
But as the above says, you can just disable Data

Just enable airplane mode

This is not always true....AT&T's branded firmware will not let you do ANYTHING with the phone without an active sim card. After powering it on the phone locks up and tells you to insert a working sim card. You can't even get to your home screen or app drawer.

Yup, same thing with an Orange locked X10i.
If the phone has a sim lock, you can't use it without a sim.

However if you have had the phone for six months you can try to ask att for the unlock code. They are supposed to give it to you.

yeah, they are supposed to do lots of things lol...don't forget this is at&t, after all. if your bill is current, youve had the handset for 6 mos and they won't give it to you, call better business and the fcc. i can almost guarantee they will fight you though :-\

[Q] Need help, bricked/nonworking WIFI after succesful sim-unlock

Hi guys,
i used a sim unlock code to unlock the ATT locked Atrix 4g, for use with a european sim card (mobitel, slovenia). it unlocked fine and i could call, but the wifi stopped working it just didnt scan/find or even connect to remembered wifis (home router), which worked perfectly before the unlock. so than i thought it might help to factory reset it, and now the problem persists and i cant even finish the wizard, cuz it wouldnt connect to the cellular (which we have 2g and 3g here) and the wifi has the same problems (so initially it finds all wlans, than after like a few secs it looses them all, i can turn off the wifi and turn it on again and the same thing happens). so i am wodering if anyone has any idea how i could rescue the phone ...
thanks in advance
ok guys i did a hard reset and put in a nonworking sim (doesnt connect to network) and i got the wifi back to working and managed to activate motoblur again. so after that ive put my working sim card in again (3g+ hsdpa+ able), and the wifi stops to work again/behaves the same as i described before. terrible ... anyone has an idea how to fix that ?
ok, more problems, now after ive put the working sim inside and the wifi stopped working, i tried with the nonworking sim (that wifi worked great before with), and the wifi isnt working with the sim it was working before either and even if i try without any sim it doesnt work... ill try with a third sim now and if it wont work ill hard reset it again
Same problem
I have the same exact issue. Anyone know what to do? I can't imagine that this is "bricked" because everything else works fine... thoughts?
where did you guys get the unlock code from?
Actually, I have a similar problem. After entering unlock code the phone accepts my SIM card, but I cannot activate 3G connection. GSM is working, try to call my other phone. APN settings are correct.
In the "hidden" settings menu (*#*#4636#*#*) I cannot chose between radio bands, but only the USA radio band.
Any ideas? Will I need to root it or even put a custom ROM (if it exists)?
So you guys used an unlock code from someone other than the carrier and are now having issues?
Wish I could help on this one. If you used an unlock code from someone other than the carrier, I would contact motorola support.
If you used a piece of software, I would wager that the software broke something and you might as well warranty return it for another.

Don't be offended, but I don't think this is the case. AT&T locked their phone to their network with standard network code (as seen in many other phones for years) so that "alien" SIM card would not work. But, additionally, since the AT&T has some value added services on their data plan (like wifi tethering) they made some accommodations (read: locked parts of the android configuration).
I am not a developer, this is just my guess, but it seams sane and probable.

No offense taken. This is why I asked about a program. Using an unauthorized code to unlock it may over write a.setting or file. Its also possible that someone broke something using adb.
Best solution, warranty it and try again

can you guys tell us what website you use to get your unlock codes from so we can avoid them? thanks
man.. this forum is dead.
even the OP stopped coming here to check his post :/
Based on your replies, I'm guessing you've never unlocked a phone before...
Unlocking a phone to be used for a different carrier affects nothing else but the ability to only use the SIM Card of the carrier you bought the phone from.
To unlock a carrier-locked Motorola phone, you simply need a "Network Unlock PIN" which is an 8 or 16 digit code that you enter to unlock the phone to any network. There is no software installation ivolved in the process.
A 3G issue will occur when your carrier doesn't support the 3G bands that the Atrix supports. Which would be: 850/1900/2100. If your carrier doesn't use any of these bands for their 3G network, then of course you are going to have 3G issues.
The Wi-Fi problem that the OP is having may be as simple as him having an antenna QA issue. But it could never be the Unlock Code.
Unlocking your phone and using another carrier other than AT&T has nothing to do with Wi-Fi issues...

I got my unlock code from cellunlock.net. It unlocked my phone just fine. Don't use that as a reason to avoid cellunlock.net. Unlocking is unlocking.
I have swapped back and forth between my prepaid sim and My AT&T SIM about 5 times so far.
WiFi disconnects almost immediately when I try to connect with my prepaid sim inserted, but I can make calls. (Atrix also displays H+, which can't be right)
With my AT&T sim everything works fine, solid as a rock.
I may do a factory reset to test things, but I have a feeling it has something to do with drivers or the network stack on the atrix, or perhaps because my prepaid sim has no data plan. It certainly isn't a hardware problem with the antenna. I am afraid to do a factory reset on the atrix while I am out of the country, considering that it requires network access to unlock itself.
To the original poster:
When you put a non-connected SIM into the phone, if you do a power reset again, the wifi comes back up solid again.
Also, is there some way we can request a merge of these two threads?

I was merely suggesting that it could be a multitude of things, but never the unlocking code or the process of unlocking itself.
Also, it can't be your SIM because your SIM has nothing to do with Wi-Fi. If we were talking about GSM and 3G then SIM cards come into play. Other than that, no way.
Have you tried using the phone without a SIM? Do you get the same problems?

I agree that it has nothing to do with the SIM or unlocking.
I just tested. I get the same problem with no SIM inserted. Screw it.. doing a factory reset and seeing what happens.
Edit:
Still does the same thing. But now I have to re-activate app sideloading.
Also, you can reactivate over wifi, which is nice.

[Q] unlockable from network?

Hi all
I am thinking of getting rid of my Galaxy SIi to get one of these. One of the ones I have seen to buy is locked to T mobile so I was wondering if it is possible to unlock these phones as I am on vodagone. If so is it a fairly easy procedure?
Thanks
Impossible at the moment. XPS is a mighty fine device so try swapping w/ some1 or something similar
Impossible? I'm chatting with my phone operator (Telenor) about operatorunlock-code. And as far as I know, the operator-code will make the phone accessible for other operators.
But the issue I got right now is there is no place to enter this long operator-code
I mean: impossible to unlock by yourself if operator doesn't allow unlocking or bills it insanely, and you don't have the money/don't want to pay such amount.

Put in a different operator's sim card and restart the phone.
It'll automatically ask you for the code

I didn't happen to have a microsim from another carrier so I decided to cut one up. For my first attempt I did a pretty damn good job since my phone recgonzied it!
Got prompted to enter an Unlock code.

My problem is that when I use a SIM from another carrier and boot my phone up, I do NOT get this: “SIM network unlock PIN” message. My phone only says "SIM card is locked" and want me to type in PIN.

Seems your SIM card is locked. I remember old phones gave you an option to add a pin code onto the sim card itself. There was a warning that if you forget it you're screwed. Try getting a new SIM from the carrier

[Q] Phone goes into "Emergency calls only" mode ?

It seems that everytime I plug my phone to the charger for few hours, it goes into Emergency calls only mode where I have no data and no calls incoming nor outgoing. Only way to solve it is to restart the phone or turn Airplane mode on and off to reset. Is this a common problem ? Could it have happened from unlocking my boot loader and rooting ?
I'm considering switching to the custom ROM "the base" in order to maybe solve this
Well I think this is new. Could just be a bad sim card. I don't have this problem and I haven't seen anyone else mention having it. I'd go to where ever I got it and have them swap the sim and if that didn't work the phone.
I would open the sd card/sim card cover and make sure sim is inserted fully. It should lock into place and need to be pushed in further to eject. I used a paperclip to push it in.

I actually had this happen to me like two days ago. I had just texted someone before walking to the lower level of a mall to go shopping. I took a look at my phone a little later and my phone was stuck on Emergency Calls with no data coming in. The carrier on the status bar wasn't even there anymore. Restarted my phone and all was fine. Not sure what caused it.
I've had this the last two days in areas I've always had great service. Wonder what's up with it.

Base rom has this enabled, or you need to be rooted and edit build prop.
I had this happen last week. I did the airplane mode toggle to clear it... but it freaked me out for a few minutes.
Running The Base, sk8r's kernel during install, no change to the LTE setting, no crazy mods applied.
I also sit in a nearly-dead-zone at work, and I have lost the data connection. Moving into the clear does not fix the issue. Reboot has been required.
This Android App Might Help
I had just the same problem with my Samsung Galaxy S2 with UK mobile provider Three.
I eventually wrote an app called which reconnects whenever it detects that the phone has got locked into Emergency Calls Only.
Maybe it will be of use to you. Search Google Play for "Cell Reconnect". Seems I'm not allowed to post links here yet...
Figured it out for my phone
I got a refurbished LG optimus G E970 from a seller online and had this issue the second day of using it. I checked to see if it was the SIM or SD card by putting them into my old phone, but that wasn't it because the old phone still functioned properly making calls/messages. I even did a factory reset on the phone. Still didn't work. I finally just decided to change the mobile networks to my provider's GSM network and it worked. Not sure why it didn't work in the first place since I never changed the network, but this did the trick.

Hello. Could you please elaborate on how you fix that issue? I'm currently on T-mobile and my unlocked AT&T LG E980 is losing signal like crazy, just briefly loses signal and goes into emergency mode only. It is so annoying though. Would really appreciate any insight on it. Thanks.

AOSP tried to *228, failed and lost LTE

As the title says I tried to reprogram my phone to see if it might pick up new towers with *228 while on an AOSP rom, the message said it was unable to program the phone and now it will only connect with 3G. I figured I could flash a TW rom and reprogram it there, however the TW just pops up a quick message saying the SIM is programmed without actually placing a call.
Is there any way to restore LTE once lost in this fashion? I've googled but couldnt find anything, I even reverted to stock in Odin hoping it would reprogram at boot but it did not solve anything.

You're never supposed to dial *228 from a LTE phone, it screws up your SIM card. The only way I have seen the problem fixed is to get a new SIM card by either going to a store or calling 611 and getting them to send it to you.
The correct way to force it to update, instead of calling *228, is to power down the phone, pull the SIM out, power on the phone, let it sit for 5 minutes, power it off and reinsert the SIM, and boot back up. Thats what works now with LTE SIMs.
I dont know if your SIM can be fixed or you will have to get a new one before LTE will work again but every time I have seen this happen the person always had to replace the SIM.

As stated above, you never use the *228 function to update an LTE device. A new sim is the solution.
Thanks guys, replacement sim is on its way.

I take it you mean a completely new SIM card, if the SIM card has already been used (like in your old phone) and you want to use it then just insert it into the phone. If its a SIM card thats already been used and you want to switch it to a new num ber you're **** out of luck. VZW only activates each SIM once and cannot, or will not, switch it to a different number.
If it is a completely new SIM card the call VZW and tell them you need to activate a new SIM and give them the info they need, which is usually just the number on the SIM card, and once they finish with it just pop it in your phone.

Disabling the radio/SIM but not the wifi

Need to disable the sim so the i717 no longer acts as a cell phone so I can give it to my daughter (who is 6). Dont need her to start calling and texting just yet :silly: and no longer use the i717 since I have a Nexus 5 now. Just wondering if there was a way of disabling it or the no sim card warning permently.
Remove the SIM card?
Or put in an old non active sim card.
I bet the screen is smashed in lest than a week.
Why do want to keep sim inside? Any specific reason?

Put it on Airplane mode and then you can just turn on the Wifi or bluetooth too if you want.
Also if you reboot with airplane mode on the missing Sim card error won't show up
