To my knowledge that won't work. He will have to insert another carrier's simcard to get the unlock code prompt.
I just received my Samsung Galaxy Tab (AT&T). I am reading various posts before I start unlocking the tab and loading new firmware.
Just 1 noob question: can the euro firmware work with original SIM card that only supports data?
Thanks,
Yes it can. Make sure you write down your apn settings and skip flashing a new modem. I would recmend Roto JMEv4 rom. I am running this on my att with no issues.

Thanks a lot for the response.
If I do get a new SIM card with voice and data in the future, do I need to re-flash the Tab to allow the Tab work with the new SIM card? Can I just flash the new modem?
Thanks in advance.
oh. I haven't actived the data-only SIM card that comes with the Tab yet ( there are 2 of them. 1 is already inserted ).
I went to check the APN settings, there was none probably because the SIM has not been activated.
Another noob quesiton, do I have to active the original data-only SIM card first because I try to flash the Tab and other SIM card with data and voice?
Hi, all,
I'm using a xt902(201m), when I inserted the gsm sim card, it can make a call, but don't have a data connection.
I have tried many methods, and now also can not solve. Any one who can help me? Thx

I want to be able to remove Sprints crapware. Should I unlock the bootloader before inserting the sim?

I might already be locked being it's a Sprint variant. Boot it up without the sim and if the unlock switch isn't greyed out then flip the switch. After that no sim can relock it

Bootloader is unlockable regardless.
From the way I understand it, if you boot the device with Sprint SIM, it will carrier lock the device. Meaning you will have to wait for Sprint to push updates for OTA.
But I am on Sprint and can confirm you can still unlock and root the device as normal instructions for the device state. And also sideload updates etc with no issue.

What are you talking about? There is no "crapware".
I bought the phone at Best buy and use Sprint. It locks as far as roaming and it hides the tethering option but I did switch the Sim and it worked on FreedomPop fine

A question: may I have the update OTA even if I am in another country? without the sprint sim card?

Is your phone the Sprint variant? If so, what did you have to do to get it to work with a Mexican sim?

If you boot into the bootloader, the phone will read "Sprint" or "OpenUS" next to variant.

no.. flashing stock firmware does not "magically" unlock a device.. if it were that easy then thered literally b no point to carrier lock anything...

Same here locked with globe, hoping that flashing thru ODIN will unlock my s10+ but sadly isn't, btw there was a group offering unlock from the carrier with 2 methods price range from 1.2k - 3k.

is your phone unlock now?
Have any of you tried the *#272*IMEI# method to change the CSC? Globe is not locked, it just appears to be because it is loading the Globe customization since it is detecting the Globe CSC. I changed mine to XTC.

This is the one that I used, but still I have to insert Globe sim card on the Sim 2 for able to use Smart on Sim1 with LTE/3G/2G
P.S. I've use TM on Sim2 and disabled it, still Smart on Sim1 is working.
