Unlock T-Mobile

Is there anyway to unlock the phone without paying to anyone?
I bought the phone from aboard and it is locked to t-mobile. And I am on a different carrier.
Can I unlock it?

I'm assuming you mean carrier unlock so it can be used with a different service provider. You have two options that I'm aware of.
1) Purchase online unlock code ( which you already know about )
2) Call T-Mobile and explain the situation and also ask for the unlock code.
If either possibility pans out, I should mention that you will only be able to unlock the phone from the stock ROM. It requires access to the stock dialer app to actually activate the hidden Unlock application.

You can use a Tmobile sim card. If the underlined portion of the serial number on the card is 260 you can just toss that in it.

It a 103 or 104 for at&t. This also is the MMS issue root problem if you are familiar.

[Q] Modem issues - cannot make calls or connect to 3g.

Yesterday, my 2013 Moto X (international model) started behaving VERY strangely. My 3g connection just died, and I stopped being able to make or receive calls - SMS works fine though, and my signal is very strong.
I can't make calls, the call just dies before even trying to ring, and people calling me just go straight to voicemail. Also, in the status menu my Network Type and Phone Number are listed as Unknown. I also tried rebooting into "Factory" mode through the Bootloader and found that my phone ICCID is also listed as Unknown. IMEI is fine though. It's so weird and frustrating.
I called my cellphone service provider (Movistar Chile), and they reset my network profile and gave me a new SIM card as well, to no avail whatsoever. The problem still persists even after a reflash (through fastboot) of the stock 4.4.4 firmware.
Is my phone dead? Or could it still be a solvable issue, be it network or phone fault?

If sms works and not phone, it's not your radio connection to the carrier, so sounds like a carrier issue if reinstalling firmware didn't help.
Did you do anything at all to your device before this happened? Though reflashing firmware should have corrected anything.
I'd be calling the carrier again.

If it were hardware, Usually sms wouldn't be working either.... Usually.

No, that's the weird thing. I hadn't done anything to the device before it happened, I was literally just chatting through the Facebook Messenger app when my data connection died and it hasn't reconnected since then.
I did call my carrier again, and they issued a ticket to tech support, so I guess I have to wait for their resolution as well.

Wait, sms works... But not phone calls Or data?

Precisely. I can SEND and RECEIVE text messages, but I can't MAKE or RECEIVE phone calls, and data is completely disconnected.

Not sure about phone, but for data... Google your carriers APN settings and see they match yours. In mobile settings, access point names.

Did you completely flash everything with fastboot and mfastboot?
Have you tried RSD Lite? Same Android version for your exact model of course. (this will wipe your phone completely.... Do backup anything important and transfer off the phone)

1. Yes, I already tried that. APN's are correct, I deleted and re-entered them just in case anyway. No change.
2. Yeah, I actually reflashed twice with different stock firmwares for different carriers with fastboot and mfastboot.

Well, it's sounding like hardware failure then unfortunately.
The only other thing to check, is that you have the correct radio installed. If you flashed stock, you should... But I'd double check. I don't have the answer to which is the correct one for you, you may need to search on that, or hope you can find someone here to compare too.

If you are within warranty period... You may want to go that route.
With sms working, I still suspect sim/carrier issue... But if they are no help, what can you do.

Yeah I know, I starting to fear hardware failure myself. I guess I'll wait to see if the carrier fixes it, otherwise I'll have to get a new phone :/

It could also be an issue with your SIM card. Maybe try turning the phone off, removing SIM and booting. Then Turn it off again and re-insert the SIM and boot again. You can also see if your local carrier store has another SIM card that they can test it with.

I got a new SIM card from my carrier yesterday, after I complained. Problem persists.

Finally, I took the phone to the official Motorola service where I live and they confirmed it was a hardware fault, and as I had unlocked the bootloader I'd have to pay an outrageous amount for them to fix it (motherboard had to be replaced). So I decided to get a new phone instead, and now I happily own a brand new Nexus 5.
Thanks for the help anyway

Is Huawei using a CSC system as Samsung? Could you enable the stock Call Recorder?

Hello,
I would like to start by saying that for several years now I have been using only Samsung Note line. I am thinking on switching to a new Huawei phone, and i was wondering if Huawei is using a similar CSC system as Samsung does.
For example, on Samsung, each country/operator has a different CSC, and each CSC enables or disables some embedded features. THL (Thailand CSC) has stock Call Recorder enabled, alongside with VoLTE and VoWiFi.
Recently it was discovered that if your phone has a more restrictive CSC (part of the big OXM CSC group)and if you do a factory reset with a Thailand SIM inside, after reset you have those extra features enabled.
Is there a similar way with Huawei?
Thanks for the support!

I am asking because i noticed that some Huawei phones have the embedded recorder activated on indian phones, while in Europe ... this is deactivated.
The same is similar for Samsung, but reseting the phone with a Thailand SIM does the trick and enables the native recorder (which by the way works flawlessly in Android 9 Pie as well!

You need root in order to have a built-in call recorder. Or, you can buy an app for recording calls from Google Play.

Thanks for replying. I would prefer not to root the phone (actually .. if i am thinking about this now .. i realised that I do not know how it is done on Huawei ... I guess you can revert back to stock and there will be no difference after you un-rooted? I mean .. there is no e-fuse that will trigger when you root it, as on Samsung?).
Also, on PIE, the call recording tools from play store will not work as before, due to Google limitations.
I was interested if the SIM reset will work for Huawei as well mostly, but i will try to get more informed about the other methods as well.
Edit : i saw that unlock code is needed for the boot loader, which leads to waranty void. I would not like to use that for now, but thanks for suggesting.

Install ACR. I have the PRO version, I am not Pie and it works like a charm.

I have used ACR previously on Oreo on Samsung devices and it worked ok. But i am more looking into P30 PRO, which will came with PIE ... so Oreo is not an option for me :|.
Thanks for the recommendation though.

I meant that I am on Pie and it works perfectly. Sorry for the typo.

Thanks for the heads up. I will try now.

Don't trust aka.petteri. It does not work on Pie, this is clearly written. Unless you turn your speaker volume to the maximum and in this case the phone will record from the mic

Same thing here ACR Pro not working.

What the...? I am talking facts. No need to turn it on speaker at maximum volume. All you are saying is nonsense, dude.

For me, ACR Pro is working fine and I am on Pie. No problems. I use it day by day.

Magisk module for EMUI 9 can be downloaded from this thread https://forum.xda-developers.com/huawei-p20-lite/development/mod-callrecord-t3798123

Thanks, but i do not want something that requires unlocking the bootloader.
What i was saying is that for some regions, this is activated by default.
The same is for Samsung, only there, if you reset the phone with a SIM from that region, then you have the inbuild call recorder, without root or unlocking bootloader.
This is what i am searching for.
THanks!

Phone is not showing built-in call recording option

I and my friend bought two Samsung Galaxy A30 devices, oen is showing the built-in call recording feature and the other is not. Let me know how do i get the built-in call recording feature?
I've googled about it, i understand it is stated that due to policies of countries this feature is blocked in some countries and is allowed in some. I am from Pakistan, and there is no such policy here. Also, why it is working in one device and not in another.
Is there any work around to get this with out rooting? I saw one solution for rooted devices of updating a file to enable this feature. But i'll need to root for that. Is there any other solution?

I am guessing one of the phones came from a country that does have a no call recording policy and the other phone didn't? Or at least the firmware originated with call recording turned off.
You are probably at this stage going to have to wait until a way to root the A30 is found imo

Don't be misled by statement above you, Phone call recording works on Samsung devices but in select countries like India and some other few Asian countries. Its a CSC feature, Once you insert a foreign or unsupported carrier SIM its disabled automatically even if the firmware region supports i.e for me I flashed a combination firmware, successfully changed csc to read INS,INS,INS and saw the feature then after just inserting my SIM it disappeared along with Data saver and Sbike and changed to INS,AFR,INS.... that's about it. My phone is not A30 but I assume its the same case.

Thank you.
So there is not any workaround discovered?

LG V40 (verizon), rooted with Android 9, no wifi calling

I got my V40 remotely unlocked and rooted. Having issues with BusyBox saying it's not installed. I'm not sure what device I should say I'm using on TWRP.
More importantly, I no longer have wifi calling and that renders my phone useless to me. At home I have no service so cannot call or text.
Can I use another ROM or a stock ROM to get the wifi calling and retain the unlocked bootloader and root?

ditto in the same boat. i also lost access to visual voicemail.
subscribed, will update you if I figure it out

Try enabling it in the svc menu and see if the setting for it comes up. Y'all are on US carriers so I can't really help much, not familiar with most of 'em. Short of it is, some options only show up when carrier and phone model jive. i.e. carrier supports the setting and phone model. Some are just simply carrier specific, meaning if you're not using the carrier fw, you're never gonna see the setting.

Sometimes you can get the options to pop up with a couple build prop tweaks. Ive used am on my mate se and my S8. But even then its hit or miss.

I'm not sure if you figured it out (I'm still trying to get wifi calling back), but I found a great visual voicemail app called youmail. It lets you do a lot of neat stuff the stock visual vm doesn't.
