Hello- I have a Samsung Infuse (Galaxy S Android) which used to be on AT&T. I rooted it and have been using Cyanogenmod ROMs as a Straight Talk Wireless customer with no problems. I recently got a t-Mobile prepaid SIM card. But when I install it in the phone I get the "SIM network unlock PIN" message. T-mobile is support is telling me its because my phone was never unlocked.
So my question is about what are my options to get this going? Can someone give me some ideas. Admittedly, I only know enough to be dangerous, so details on what to do would be great.
Thank you.

So I've done a large amount of searching, not only on XDA but elsewhere to find a real 'answer' to my question, but I haven't found anything concrete, hence this thread.
I have aquired a Droid 2 Global from VZW for free, and I want to use it with my US ATT SIM, on the US ATT GSM Network.
Things i have done:
- Flashed the phone to the stock OS in order to....
- Flash the radio so it accepts ATT GSM signal
- Aquired the sim unlock code from ATT for my current phone/sim (I'm unclear on exactly what this whole sim unlock process is about, perhaps why I'm asking)
The phone boots, but when I have my SIM inserted, it asks for the unlock code.... What exactly IS it asking for?
The SIM unlock that I recieved from ATT doesn't work.. (I assume this is the unlock for my sim, in my current phone?)
What is the next step, if this is possible? I've looked at getting the phone unlock code via ebay, or one of the piggyback devices like TurboSIM, but I'm unsure what will work, if anything will work?
Help??
Thanks in advance for any info provided
It asks for the unlock code you can get from VZW's Global Support if you are a VZW customer.

Well, since I'm at ATT customer, how would I go about getting this code? I do have a friend that works for VZW, which is how i got the phone, and he is willing to assist me. Can he provide it?
The phone must be on an active line of service, and the billing history must be clean for the past 6 months.
If your friend works for Global Support, then maybe. If not, I doubt it.
Hmph..
I guess I overestimated the difficulty of getting this to work. It was just another case of having to get the unlock code from the phone itself via IMEI number,and yahtzee, working as I had hoped.
For some reason I had the notion that it was significantly more difficult after reading all of the posts about trying to get other SIMs to work.. but its actually very very straight forward and easy.. it just seemed that nobody had ever really made it clear that a US ATT sim could work on a VZW D2G handset with US ATT service.
Thanks for your input!
I asked this question a few days ago & no one answered, so I will try a different way.
Verizon tells me that my phone that is "unlocked & rooted" with CyanogenMod 10.2.1 is not truly unlocked.
So how do you completely "unlock" a phone so that it will work on Verizon's CDMA network?
Is there a different way to unlock for CDMA?
Thanks.

If your running cyanogen mod your bootloader is unlocked. There's two different kinds of unlocked, one is sim unlocked which means it can run on almost any carrier and bootloader unlocked meaning you can flash custom roms
As far as CDMA not that I'm aware of

Thanks. I couldn't understand how a phone can be unlocked & rooted & still not be unlocked. The salesman at Verizon told me on the phone that whatever company originally sold the phone would have to unlock it. I forgot that this was a T-Mobile phone. I use T-mobile sim via Straight Talk. If this sim is removed then would the phone be able to work on Verizon network? Verzion is telling me this is a GSM phone & not CDMA & won't work unless unlocked by carrier. Which makes no sense if it isn't a cdma to begin with. I assume that all Verizon version of phones are made for them as CDMA only?
If this is so, then Verizon should not be advertising "bring your own device" as it won't work. It should be "bring your own Verizon phone".

Verizons idea of bring your own device really isn't what it should be. It should work on the vzw network but all phones should be sim unlocked by the carrier as a law was passed to do so, however verizon won't a lot of times sim unlock it like it should be until the contract is fulfilled.
And yes there bring your own device is irrelevant because most gsm phones won't work like they should on this crappy network because they are the only CDMA only network left.

Thanks ShapesBlue. I assumed it was not really bring any device to play as they state. My phone came from T-Mobile from the original buyer, so I don't know if T-Mobile would till unlock it or not since it isn't stock any longer. I have a friends that use Verizon & they get good service in our area. Mine is limited on T-Mobile, lot of dead spots especially where I work & slow data. I had a non digital CDMA phone that I used through Straight Talk & it used Verizon network & I got good phone service in places way off the beaten trail, so that is why I wanted to try Verizon again.
Where can I find a copy of the "unlock law". I searched for it but didn't find anything. I would like to print it out & take with me for proof.
Thanks.

Hi Everyone
Heres a neat problem somebody may be able to shed some light on.
I have a samsung galaxy s2 hd lte I757M , it just expired off of contract from bell.
I wanted to unlock it and was ready to when I decided to check if the phone was locked by using *#7465625# and it says that everything is OFF so that means its unlocked, from what I have been reading.
I bought a sim card from roam mobility and booted it up. It did not ask for any code for unlock. It only says "No Sim card Emergency calls only. I installed it properly exactly the same way as the original one came out. Its clean to.
(Keep in mind I bought this phone brand new from bell never serviced or rooted)
I spoke to roammobility and they say the phone is supported on their network.
I thought the sim maybe defective so I tried it in a locked samsung galaxy s2 i9100m and right away when booting it asked for a unlock code, so to me it sees the sim is there. . I also tried it in a locked moto g with the same results..
Can anyone tell me why my phone does not read the sim or see it? Could this be some other type of lock?
My stepson got my wife a Samsung Galaxy Mega 2 SM-750a for Xmas because we are switching from Verizon to Ting and our old phones are locked to Verizon (plus they are old).
When I put the Ting GSM SIM card in the phone is prompting me for an network unlock PIN, I requested an unlock from AT&T, and after 5 days they came back with this.
AT&T said:
Thank you for contacting AT&T about unlocking your mobile device.
Unfortunately, your unlock request was denied because:
Your device is no longer supported, and we can no longer obtain the unlock code from the manufacturer.
Questions? Please call 800.331.0500, or dial 611 from your AT&T wireless phone.

What are my best options to get this phone working?
I called Sprint and had them unlock my rooted, stock-Android 6.01 (G900VPU3PCA) SM-G900P Galaxy S5 for domestic and international. Sprint also gave me a 6-digit MSL unlock code.
I inserted a new, T-Mobile SIM card into the unlocked S5 and I activated the SIM card on T-Mobile's website. However, the phone displays "Invalid SIM Card" in the notification area, and I get no voice or data. I tried restarting a few times. I also tried dialing ##72786# to reset the PRLs a few times. It won't activate. It still displays "Invalid SIM Card".
T-Mobile reps say to call Sprint.
Sprint reps double checked that it is unlocked and said that:
1) For Sprint phones built prior to February 2015 (like the Galaxy S5, but not the S6, S7, etc.), unlocking only truly works for non-US SIM cards & international use.
2) Domestic unlocks only work if the domestic carrier is willing to work with you to reprogram your phone using the "unlock" MSL code that Sprint gives you when you have them unlock the phone. T-Mobile is not willing to help me reprogram the phone.
3) I did find a site (idoneapps.com) that claims to be able to unlock the phone and fix the "Invalid SIM card" error for $35. But for that price, I'd rather just sell my Sprint GS5 and buy a T-Mobile GS5 because the Sprint G900P doesn't support T-Mobile's LTE bands. (It only supports HDSPA+, which is probably fast enough, but may not be common throughout the USA).
Can anyone help me figure out how to get this phone activated on T-Mobile without paying a fee?
I struggled with this. Idoneapps used to have a free version that worked for unlocking but it has since been scrubbed from the web. I went ahead and paid for the service, and it workeds well.
Since you got the unlock code and already performed the unlock. I recommend getting the free galaxy tools app that was made prior to it becoming idone.
I used version 3.12
Check sim lock status, if still locked go ahead and unlock then use idoneapps recommended steps to enable tmobile service.
You need to change the gfc settings. This might let you use another sim card.
