Okay, so I'm pretty sure when I bought this phone with contract it was network restricted.. I changed my carrier yesterday to t-mobile, so I bought a sim unlock on the net. I received the SIM unlock code, I couldn't get to the input field though (I'm on CM10), but then I was playing with settings and I could successfully connect to T-Mobile, however the signal is weaker than it was before and it has disconnected twice, but still.. so I don't need the unlock code no more am I right? It was cheap so it doesn't matter, I just don't understand how can this phone can be unlocked.
Just curious, what was your original provider? I don't know specifically about T-Mobile, but some carriers allow other SIMs to be used, because they are sharing networks. For example, if you have a locked Rogers phone in Canada, you can use it with a SpeakOut SIM, because SO is riding on Rogers network. Could it be a similar situation for you?
But it's strange that you don't see a prompt for a network lock code when you insert a non-original SIM... I also had to unlock my phone by code, and I got the prompt right after putting in a different SIM. Could it be because you are on CM ROM? A general recommendation is to always unlock you phone from a stock ROM, before flashing a custom one. I am not sure about this, but just thinking out loud...

I was on Telenor Hungary, now it's T-Mobile, they are whole different providers, no relations at all. Well yeah, I've thought about that stock ROM thing too, but I still don't think it would connect to a different carrier because of the custom ROM. But it works strangely though, couldn't set up mobile net yet, and when I was on the T-Mobile hotline, it disconnected and the phone said the SIM might be corrupted.
So I tested, I can make phone calls, but everytime I reboot the phone I have to connect to the network manually from settings.. So I'm gonna try with stock ROM, and use the sim unlock code. Can I also use stock-based ROMs? Thanks.
Hi. I have a GB xt1068 (dual SIM) and am wondering what the second SIM will allow me to do. It it simply like having two mutually exclusive phone lines in one handset (e.g. need to activate one or the other) or can they work together (e.g receive call from either)

Dual SIM is useful for various situations. I personally use it to both have a cheap 3GB mobile internet (tablet contract) and a cheap phone/SMS (prepaid), since there are no contracts for that much data+phone for a low price where I live.
When you are travelling a lot, you can use the second SIM slot for a SIM from a local carrier, so you don't have to roam but still can be contacted with your number in the original SIM slot.
You can also use it for your work SIM, if you don't handle crucial company data, so you don't have to carry around two devices. After work, you can easily disable the SIM, if you don't want to be contacted any more.
However, AFAIK, the Moto G 2014 only has one GSM and one HSDPA modem for both SIMs. So you can not have two calls or two data connections at the same time. But it is easily possible to switch the SIM (for example right before a call, you can decide from which SIM to call).
Hope that helped
Note that one sim will use 3G only and the other will be 2G for phone calls. So if you plan on use a three network sim for phone calls then the other sim will be downgraded to 2G so you will not be able to use data on that at the same time.
N-920C Region lock asks for Sim network pin.
I purchased Note 5 model N-920C from Saudi Arabia but when I came back to India with an Indian simcard it asks for Network Sim Pin and if I discard it says invalid sim card or network locked sim card inserted.
Can anyone please help..
Thanks in advance
i have the same prob... anyone pls help
Saudi phones are region locked to prevent theft and black market sales. In order to unlock it you should insert a Saudi SIM like zain, stc or mobily and place a 5 minute call (whilst in saudi).

I bought my phone too in Saudi online but my sim works from my country in Philippines.. I did some tweaks on my phone but when I flashed a stock rom, it now asks for a network pin unlock ?. Help! (I don't know how to start a thread ?)
You have basically 3 options here to get rid of the region lock.
1. get a SIM from the country the phone originates from. Make a 5/6 min call to a mobile number. That should remove the region locking after this you should be able to use any SIM you like.
(note) You must call a mobile number from the phone and NOT a landline. And secondly if You do this procedure from outside the home country of the phone that call will be considered to be a roaming call and will cost more than a regular call.
This procedure is intended to be done to activate a phone with a local SIM while STILL in the country of origin and may NOT work if the phone was NOT activated with the original SIM of that country. It may be possible to still make this work by performing a factory reset and using the correct countries SIM card and performing the above procedure.
2. Look for one of the many phone unlocking web sites that offer a regional unlocking code and buy that code. (Note) the region unlocking code and the network unlocking codes are NOT the same thing so even after you have gotten rid of the region lock you may still have to get a network unlocking code if the original network operator has locked the phone to their network.
The code you need is the RGCK unlocking code. You maybe able to also get this code from the Samsung agent for the region the phones is from.
3. Speak to Samsung for the region that the phone was sold and intended to be used in. You maybe able to also get the RGCK unlocking code from the Samsung agent for the region the phones is from.
(note) this option will may require that you return the phone to Samsung for that region and they can remove the lock. This is likely the most costly option.
I hope that this info is of use to you guys.
1) My friend (U.S.) gave me (Canada) a T-Mobile Galaxy Note 4. I am trying to use it with Wind Mobile.
2) He claims that T-Mobile performed a carrier unlock, which seems to be confirmed because putting a foreign SIM card in does not ask for an unlock code.
3) My Wind Mobile SIM can't register on network. I tried a Rogers SIM as well and a different Wind Mobile SIM and they didn't work either.
4) The Wind Access Point Names have been entered, but manually selecting the network does not work either. It just says "Unable to connect, try later".
Am I missing something here? Is there another type of lock I need T-Mobile to remove? Do I need to flash the ROM? Thanks in advance.
If same sim cards work in other phones i would think that phone is blacklisted. On the other hand nowadays tmobile can issue temporary unlock codes for international travel. I dont know if Canada is considered international or not. Tmobile will permanently fully unlock device when paid off.
Hello,
I have just acquired a new (never used) T-Mobile Revvlry Plus XT1965-T, and it seems to be network locked. (Note: I was able to get an OEM unlock code from Motorola, haven't tried it yet, but right now I am only asking about the network lock issue.)
My goal is to install LineageOS 18.1, and use this phone with other mobile service providers in Canada.
I want to understand how to deal with the network lock, and get past it -- I have some questions...
1. If I simply follow the official instructions for installing LineageOS, will this result in a network unlocked phone?
2. If just installing LineageOS won't remove the network lock, why is that? How is the network lock implemented on this phone?
3. Is there any way to clear the network lock, without going through T-Mobile?
4. If I must go through T-Mobile and use their unlock app, I assume that I had better do this before I do anything else, and once the phone is network unlocked using T-Mobile's app, then the phone will remain network unlocked after installing LineageOS, is this correct?
5. I get the impression that there are actually two different phones with the same model number XT1965-T, being the T-Mobile version and the Motorola version, is that right? What are the main differences?
Any other comments, insights, or links are also appreciated. Please keep in mind that while I am highly technical, I am not an expert on Android or smartphones.
Thanks.

1. No, network lock is related to the carrier. If it's a TMO Revvlry+/Revvlry Plus, then it's locked to T-Mobile. This means it can't be used with another carrier essentially. Network lock again just means if a TMO sim is installed (and it's locked to TMO) it will work. If another carrier sim is installed and it's network locked, the sim won't function.
2. If the phone came from TMO, they would lock it to their system.
3. Removing the network lock allows other carriers to be used. There are pay to use services that will network unlock the device within 24 hours. Manual methods exist, but will require more in-depth knowledge. Otherwise, TMO is the one to network unlock it but could take 30 days and may require service with them.
4. Once unlocked it should remain unlocked, regardless of stock or custom ROM.
5. The TMO Revvlry+ (Revvlry Plus) and Moto G7 Plus are the same devices hardware wise. The main difference is the boot animation and logo branding. The Moto G7 Plus is also carrier unlocked.
How did you determine the phone is network locked?
Is the phone tied to a network carrier already?

Thanks for your reply, here is some background...
I bought several of these phones on eBay, they were advertised as network unlocked Moto G7 Plus phones, but the seller instead shipped me network locked T-Mobile Revvly+ phones.
My first step was to test a SIM chip from a local mobile provider, and the phones show a message saying they are SIM locked.
The phones are clearly new and unused. The seller claims they are open-box returns.
I called T-Mobile, and T-Mobile says these phones are registered to active accounts, and they can only be unlocked if the account holder requests it. T-Mobile reps also say they are unable to identify the account holder, and offer no solution. The phones are not blacklisted or reported stolen. If I had to guess: most likely, the phones were purchased, activated, and returned to the store, but the T-Mobile account registration was not cleared in their database.
It seems that these phones use an unlock app, rather than an unlock code, and from what I've read, it may not be possible for any third-party unlocking service to unlock these particular phones.
Getting back to my questions in my original post:
- How is the network lock implemented on this phone? (I mean this question from a technical perspective)
- Is there any way to clear the network lock, without going through T-Mobile?
The network lock must be a setting somewhere in the firmware... I've heard people talk about flashing the baseband, but not being a phone expert, I don't know much about that, or if it might apply here...
So again, I am asking: is there some way to network unlock these phones, and make them usable with another service provider? Can I somehow just reflash whatever area in the phone holds the network lock setting with stock code that doesn't have the network lock setting enabled?
Thanks.

If they are registered and active, they may have to wait out the time period from T-Mobile to be Network SIM unlocked, depending on when they were originally purchased by the original owner.
If they were returned to the store, how did the eBay seller obtain them?

If an unlock app is needed, this may be built into the phones firmware that only T-Mobile can use. It may still require a code to be passed to the unlock app.

It's implemented by T-Mobile. T-Mobile is going to be your best shot. You may have to make multiple calls to get through to someone where you can explain the situation and see if they will network unlock the phone.

Baseband typically indicates the frequencies the phone can use to communicate with different networks. If you take a nandroid of the phone, you can always try to flash a new baseband and test. If it doesn't work, restore back.

You can try to flash the T-Mobile Revvlry+ into a Moto G7 Plus: https://forum.xda-developers.com/t/revvlry-to-moto-g7-plus-conversion-guide.4136355/ That would get rid of the T-Mobile software. It's not clear if that would remove the network SIM lock, but if you take a nandroid backup, you can always revert back.
EDIT: I was doing some additional research, and flashing the modems/baseband or converting the TMO Revvlry+ to Moto G7 Plus won't affect the network SIM lock. The app is in the TMO software and you'll have to use that app with the code either TMO provides or an unlock service gives to network SIM unlock the device.
EDIT2: After booting into the phone, do you have the options in the following settings: SIM unlock phone. This link is only for info and reference: use any network provider’s SIM card in T-Mobile REVVLRY+

As mentioned, the phones are clearly brand new and never used.
I would also like to know how the seller obtained them, unfortunately the seller is non-cooperative.
T-Mobile is also curious about how the seller obtained them.

I am still not clear as to why the phones can not be unlocked by replacing certain firmware/software. The lock is a setting somewhere on the phone, why can this setting not just be manually changed/cleared?

The app is provided via TMobile. This is not provided via software/firmware except by TMO.
Your best bet at this point is to try a pay to unlock service that will provide instructions on unlocking the SIM, if TMO is unwilling to do it.
(Modems change the baseband used by different providers so changing/updating it via firmware isn't going to unlock the SIM/Network. If you get the SIM/Network unlocked and THEN have an issue with a network carrier, flashing the correct modem for that provider would allow the SIM/Network to communicate.)

Do have service with TMO? If not, you might try getting a SIM/Network card from them and inserting it to see if the in-phone options appear so you can unlock it. You might also try escalating the issue with TMO if you are only getting to first line technical support personnel.
The phone is obviously locked to TMO as it's a TMO phone. It's different than the Moto G7 Plus which is already unlocked for all carriers. If you can't get the phone Network/SIM unlocked, maybe return it to the eBay seller and look for the Moto G7 Plus which will give you less headaches.
