[Q] Is it possible to unlock my Xperia C (Sim1 is carrier locked)

Can you help me guys? is that possible? Please note that i am not talking about the bootloader. I got my phone free when i got a postpaid plan on my carrier. the SIM1 is locked(not openline). SIM2 is unlocked but its GSM only(2G). i need to insert a different carrier sim on SIM1 which is WCDMA/GSM(3G) to use it for internet. i'll put my postpaid sim to SIM2 because it's internet connection is crappy. thanks!

When you flash generic firmware with WMShua Flash Tool, your SIM1 and SIM2 will be unlocked. You can use any SIM Card you want.

You should follow 2.14.J.0.68 instructions and just do first 3 steps. The others are for custom recovery, you don't need to do it.

^This. You need to sim unlock before converting to international, or you will be unable to unlock the bootloader and have OEM unlocking. At least until they fix the MSM to be able to skip sim unlocking.

Yes, you can try it that way. If the device is already fully paid off you can also simply contact Tmobile and they will be able to sim unlock it for you already as well, or if you haven't paid off and want to chance it, you can try contacting them on twitter or through the tmobile app and try to get the customer service rep to unlock it. Though if you haven't paid it off it's probably easier and faster to DM the OP from that thread.

I have the international version and am also stuck with the greyed out OEM Unlocking option. My bootloader is also still locked. Any help would be very much appreciated. I have tried using fastboot to oem unlock but I get this error
FAILED (remote: Please enable OEM unlocking in developer options first)
finished. total time: 0.007s
It was on a Chinese ROM before and I did use https://oxygenos.oneplus.net/Fulldowngrade_wipe_18821_190425_0253_user_fix_revision_MP_release.zip to downgrade so I could switch to the English ROM.
I also have a one plus 7 pro. It has been carrier unlocked but still the OEM unlock is greyed out. It is running Android 10. Is there a way to 'ungrey' the OEM unlock option? Thx
Do a search for this "The T-Mobile OnePlus 7 Pro’s bootloader can be unlocked by flashing Android Q" and fallow the instructions. Instruction are on xda.
There is no need to unlock the sim on the T-Mobile phone to unlock the bootloader.
Phone needs to be on the international firmware. This can be done with the patched msm tool. Then downgrade to android development preview 3 using local upgrade on phone. Unlock via fastboot and finally root and install a working rom or do the rollback to android p via local upgrade. Search for the guide and fallow the instructions. It really simple.
Kind of related. I converted my t mobile oneplus 7 pro to the international version and am eligible for a sim unlock. I tried to do it over chat but they said since it's not their version of android I would have to do a factory reset (which wouldn't convert it back to t-mobile stock) in order to sim unlock it, does anyone know how to sim unlock it on the international version with t-mobiles help. I would have thought t-mobile could just do it on their end but I guess not, and I guess they are kind of idiots over there to, because initially they had no idea what i meant when i said i converted it to the international version (heck they still didn't understand that I changed the firmware/ROM) so resetting it wouldn't make it a t-mobile phone again.

Backup everything you might need and revert back to T-Mobile stock firmware with msm tool. Use the provided app by the T- Mobile stock firmware to unlock sim.

You either didn't follow the correct guides. Or did something incorrectly. I bootloader unlocked my t mobile sim locked device

T-Mobile version

Can the T-Mobile 7 pro be converted to international and utilize dual SIM? Yes would need a dual SIM tray but would it activate the feature?
Yes, the tmo version is dual SIM after international conversion provided you sim unlock via tmobile first.

No need to wait 40 days, go here or here to get the unlock done for you or go here too use the dp3 bypass.

Can't unlock T-Mobile device network

Just a noob question?
Long story short I haven't had success unlocking T-Mobile..
I think I can unlock boot loader with msm tool.
My question is if I successfully unlocked Boot loader and flash any custom ROM will I be able to use any SIM?
Thanks

Yes, your warranty will be void but unless you're really rough physically with your phone, there's almost nothing you can do to it that the folks here at XDA can't fix!

If nothing else, you can always use a separate MSM tool and revert it back to the T-Mobile version. No harm, no foul.

I think I read something about using MSM tool to flash EU or GLOBAL firmware and not need to request unlock code (which voids warranty) because I can unlock boot loader on the spot.
Can I revert to T-Mobile firmware with locked boot loader just I case if I have to return it for warranty
Thank you very much

The link I provided will convert your T-Mobile version (KB2007) to the EU version (KB2003).
If you need to go back to the T-Mobile version, there is a separate MSM tool to do that, it will also relock the bootloader at the same time for warranty purposes.

Another question
Can I convert T mobile to global firmware directly or is there any special process?
Thanks
Use the link I sent you. That will convert it to the EU version. Setup your phone using just the defaults. Then download Oxygen Updater from the Play Store and within the app you can choose what version (Global, India, European) you want to install/upgrade to.

I just got my unlock stuff from OnePlus and I know there is a thread on here for converting but from what I see it is to go to EU firmware and has some other steps I assume that are for rooting. I don't want to root I just want to install the USA...

Flashing to a different firmware does not alter the SIM lock/unlock state. If your device is SIM locked to T-Mobile, it will remain SIM locked to T-Mobile after flashing to the Global, EU, or other regional firmware. T-Mobile devices can only be SIM unlocked on the T-Mobile firmware.

No. You can only SIM unlock the device on the T-Mobile firmware. Flashing to EU or Global only allows you to unlock the bootloader.

You need to meet the SIM Unlock requirements for T-Mobile to process the SIM Unlock for the device Then using the T-Mobile Unlocking app, go through the steps and select Permanent Unlock. If it completes, the device will restart and will work with any carrier SIM.

If T-Mobile doesn't want to unlock my device. There is no other path? I have tried a lot of times with a T-Mobile rep they say it wasn't purchased at T-Mobile directly. Please help?
Thanks
I think they are websites that supposedly unlock Sim or devices.
Any ideas on that?.
