Smartphone with every kind of SIM ? - General Questions and Answers

Hi everybody,
I have already flashed a new ROM (ICS 4.0.4) and I have superuser permissions (root) but,
Is it possible to use my smartphone with some other company SIM card? My mobile phone is an Lt15i (Xperia Arc) and i bought it in Spain (with vodafone) ... now i am in germany and i want to use my new FONIC SIM...
What can I do?
Thanks in advance.
Fernando.

If I install a custom ROM, will i get make it? Which custom ROMs do that? What unlock Bootloader means?
Thank you.
Please help me. I'm a bit lost.

If it's an unlocked GSM phone, it will work with any GSM carrier. I don't know if your phone is carrier locked or not, though. Also, custom roms don't control which carrier you can use.

You don't need root or ANYTHING to unlock your phone.
1) get SIM that is not the network the phone was originally on
2) buy unlock code from local dealer or trusted ebay seller. You have to give them your IMEI I believe
3) put that SIM in and when prompted, enter unlock code. Phone is now unlocked for any SIM card for eternity

[Q] Help!!I have atrix 2 AT&T locked

I have a Atrix 2 AT&T sim locked .If I install a custom rom like Supercharged Atrix, will be unlocked to any network mobile ? I live in Costa Rica, I bought my phone on ebay like new, unmodified and without contract,but I dont have money to buy the unlock code in cellunlocker.net. It is necessary to unlock the bootloader to unlock the sim card ? I Search in all the forum to see if the doubt was resolved but did not find anything.Somebody help me please!!!
No, it's not necessary to unlock the bootloader to have your sim unlocked.
That is a network provider deal.
Our bootloader is currently "UNLOCKABLE".

I don't think installing custom ROM will unlock the phone for all carriers. You have to do unlock separately if you want to use with any provider other than AT&T.
SIM unlock is entirely separate from changing roms, the bootloader and all that stuff.

Currently our bootloader is LOCKED. Installing the SC ROM will not unlock your phone. To unlock it search on eBay for an unlock code. This right now or the only way to unlock your phone.

He means to SIM unlock the phone, not bootloader unlock....
a sim unlock is about $16.00 USD, just search ebay for atrix 2 sim unlock code.
I got mine from here

[Q] HTC J ISW13HT - any japanese here?

so the HTC J ISW13HT was released in Japan 10 days ago, and I'm eager to get my hands on it. Only I am not in Japan.
Are there any people in Japan here on the forums that can answer some questions for me?
Is the phone locked to au? And does the phone in fact support GSM sim card at all? I know it has a card slot but since au is CDMA I wonder if the phone accepts sim cards (it has GSM functionality).
cheers

Hmm, I suppose when I get my hands on one, I'll be able to answer this question. I'll try to stop by an au shop to poke around one of their display models.
I'm assuming the phone is locked to au, though.
nice, thanks. Does au sell phones without contract at all?

I think you can purchase the phone outright but to get it unlocked you'll have to pay for the unlocking fee which is about ¥3000. Even then, I dunno if it has a removable sim card

Any more info?
It's been about a month now since this was posted, any new info?
I live in Japan and have the phone, but can't find much info for Root yet (in English at least) or Sim Unlock if it's possible or not.

Have you downloaded the ruu for it?
If you get that you can probably add su and busy box to it and maybe look at the one s threads for a root method

It does support GSM/CDMA/WCDMA/WiMAX
But the GSM/WCDMA function seemed to be locked by AU.
You could not use GSM/Wcdma network when you insert a GSM/Wcdma Usim.
I have this phone, unlocked the bootloader, root, but can't make sim free.
I can't post links, only after 10 posts.
I have translated scripts for one click root.
Does anyone know sim unlock is possible for this phone?
Now the J is also in the market of HK and Taiwan. Hope someone can cook ROM for us.

Are the HK and Taiwan versions of J also simlocked?
I made ROM for J based on MIUI for One S. But I still can't unlock simlock.(
Taiwan versions of J does not have simlocked.

Anyone can translate this into English? Seems a fair amount of info in Japanese, but nearly nothing in English... Google translate works very poorly from Japanese, don't really trust it for this.
Also, once you've flashed the radio from the Taiwan version, does it still work on AU? I don't want to change carrier to Docomo/Softbank, but I want to use local sim cards when I travel.
So whats the steps to unlock this little guy?

Root, Custom Rom to Unlock?

Hello,
From what I have read if I understand correctly if I root the verizon droid 2 global, then install a custom rom the phone will be unlocked and I can use any provider outside the usa.
Can you confirm if this is in fact correct?
Also I live in Florida but have a german cell phone with a german chip that I use here in Florida. If the above does unlock the phone, when I put my german chip in the phone will it work in the usa or do I need to also do the band unlock first?
Thanks
JB
No. Custom ROMs don't support the SIM unlocking mechanism of the D2G, nor they disengage the SIM lock.
You have to unlock the device with an unlock code to use it with SIM cards that aren't Verizon-issued.
Thank you for the information.
I guess there is no way someone can shoot me a bone and provide the unlock for free since ive been a member for 3 years? It would be appreciated greatly...

The unlock code is specific to each handset, so no-one has one that they can give you.

It should be sim unlocked out of the box. Have you stuck a sim in the phone and tried to add Telus APNs?
The only root exploit available for the VRUDNE1 4.4.2 OTA is to use Towelroot. There is no bootloader unlock available for this OTA which means there is no chance for AOSP nor downgrading the firmware to anything prior to 4.4.2. Safestrap is available but you would only be able to dual boot another VRUDNE1 based rom, nothing else.

Of course it didn't, the sim card would belong to the previous owners phone number etc. You need a sim from your carrier with your info, phone number etc. See my post http://forum.xda-developers.com/showthread.php?p=58582227

Unfortunately I can't. I think the true owner of the phone is required for unlocking it. I need different ways to unlock it. Can I just install another samsung s8+ firmware to this phone?

No. There's no firmware or ROM that will SIM unlock it.
You'll need to have the original owner unlock the phone for you OR purchase the phone already unlocked - no software can unlock it for you.
Docomo and Softbank are extremely strict when it comes to unlocking a phone, you need to have an account with them for a few months, pay off the phone, and you'll be able to unlock the phone. If you don't then having it unlocked *remotely* is out of the question unless you sent it to someone who can unlock it for you.
Sorry to revive the thread after so long.
I have similar situation. I have a NTT Docomo s8+. I have unlocked it as well, it now works with my ATT sim in USA.
problem is the annoying Docomo apps in Japanese.
I am not able to rid of it completely.
Can I flash a US-Unlocked stock ROM or any custom ROM ?
pls let me know how.
Pls note my phone is Snapdragon based, (unfortunately most ROMs are for Exynos version).
