I purchased a used S4 from Tmobile from a guy who say he broke it so just upgraded. It's a Tmobile phone but is locked to Tmobile at least it seems. If I put a Metro pcs Sim in its not saying locked lije it does with my At&t Sim. So does this mean it's locked to anything other than T mobile and metro ?
Also Swappa says the following can somone explain ?

I just bought a brand new Samsung Galaxy S3 with a contract from ATT&T, the 747 model Without attempting to unlock it, I stuck a prepaid redpocket SIM card and the phone works. Does this mean my phone is unlocked for all carriers? I don't have any other SIM cards to check. I searched on here to get confirmation on how to check if phone is locked, the *#SIMLOCK# does not do anything on my phone.
Anybody else bought the phone from Att&T and it happened to be unlocked?

Red Pocket is an AT&T MVNO, so it is still locked.
Hello,
Lately I bought a Galaxy S4 AT&T carrier, but the guy who sold me did not say to me that the phone has bad imei, so i was unable to use it because my AT&T Sim Card when I try to call on this phone said that the network was blocked......
So I return this S4 and I return to use my Original phone back, (a Galaxy S3 AT&T) but when I try to used the phone, said the same thing that the network was blocked for Network use on AT&T.
The thing is, I unlocked my own S3 for used with another carriers just for fun and I rooted it, if I go to AT&T to solve this problem can I had a problem with they? because you know, unblocked phones is illegal.
How I can have network again?
Please I hope an answer, I am 3 weeks without phone
I'm a Canadian (Rogers) customer. I just picked up my TMobile (bad IMEI) Note 3, that I purchased off EBay, hoping to unlock it and use it on the Rogers Network back at home. I was told that the IMEI is bad. I'm staying here (USA) for a few days so I bought a TMobile Pay as you Go Sim for my Unlocked S4. Experimentally, I slipped the SIM card into the NOTE 3 that was supposed to have BAD IMEI, and it works!!! Is it supposed to? It's on 4.4.2, now i'm hearing its not unlockable.. true??? HELP HELP HELP!!
It's not supposed to. Keep using it and see what happens and report back to us
This worked to unlock mine. I'm on T - Mobile and I'm no longer carrier locked.

Try checking the imei on T-Mobile USA website it should tell you if bad, swappa lags behind on status. If it is bad it will probably take a month or or more to actually register on the network and get flagged
Hi
I have a carrier unlocked T-Mobile s8+ and need to use a Verizon SIM in it and am getting errors trying to use a verizon SIM. The Verizon SIM is from another phone and is already registered. I put the IMEI number of the phone into Verizons web portal to test compatibility and it failed. Does that mean there is no way to get this combination to work? Does the IMEI need to be in the VZW database for this to work? Will flashing XAA guarantee this to work? Thanks for any help and advice.

do u have a tmobile phone, it is different than the carrier unlocked phone, those are 2 different models,
the carrier unlocked.. the sim is unlocked..
the tmobile is not carrier unlocked, and by flashing the firmware of the unlocked version, will NOT unlock the sim.. u will need to device unlock app with the tmobile phone 1st... and usually tmobile will NOT unlock unless u have paid it off and using on their system for 40 days..
others like me had it unlocked with days of service, cause we are tmobile customers for years already... I on the other hand bought the phone on ebay from someone who bought it from Samsung and the imei was not added to tmobile system and I had to call tmobile to add the imei which took about 3 days, then to call back to request the sim unlock which took another 3 days, the device unlock app unlocked the phone instantly...
that was my process for me to get the sim unlock... but if urs it not unlocked and is paid off, another way to get it unlocked it to give it to someone u know, let them use it and call tmobile to start the above process...
Hope that sums up what must be done...

Hi thanks for the explanation, I am pretty familiar with the differences between carrier (SIM) unlock and unlocked firmware as I have flashed Android in the past. I had the phone carrier (SIM) unlocked by T-Mobile through their app and I was still not able to use the Verizon SIM in my phone (not registered error). It turns out (and I found this out by reading through the many messages in this forum) that T-Mobile firmware apparently disables some frequencies that other carriers may use. Once I flashed the XAA unlocked *firmware*, I popped in my Verizon SIM and it worked like a charm. I hope this info is useful to someone at some time and I thank all of you for your contributions to getting this working. KUDOS!

Good to know, but sound weird, thought T-Mobile phones work for all gsm Sims just needing to change apn,
But now cdma merging with gsm, that's so much better as far as phones go, use any phone now from any provider.
Look how the s8 plus is all the same software and the same hardware, just different carrier stuff..

I thought it was weird too. Busted my head for a couple of days trying to figure it out. Is Verizon still CDMA? *scratches head*
Yes, their 3g and 2g networks are CDMA.
If you insert Verizon sim into T-mobile phone, you'll get LTE data, but you won't be able to make calls. Only data will work. T-mobile firmware support band 2, 4 and 13, so you should have data, but not phone service. If you don't have data icon, you'll need add Verizon apn.
FYI
Flashing the phone with G955U1 firmware fixed this issue. I am now able to use this successfully on Verizon.
Ok long story short I got the phone off fb marketplace supposed to be unlocked but of course mt att prepay sim says invalid... and does not prompt for unlock code
looking into the phone it doesn't have a sprint rom as the rom ends in JETER_NA_CUST and not sprint... plus there is no sprint bloatware or anything.
but going to UICC Unlock it does say it is locked to sprint....
and it does say sofware variant sprint and software channel sprint
anything I can do to get my att sim to work
Nope. You bought a Sprint/Boost Mobile device which uses CDMA like Verizon. AT&T, as well as T-Mobile, use GSM.

I have mine on boost and the basband still says jeter_na_cust just like yours. It's a sprint/boost rom. You definitely bought the boost/sprint variant. It won't have sprint bloatware but it should have boost Mobile bloatware. If not the person you bought it from tried to flash the retail version from Best buy onto a sprint/boost variant. I hate to say it man but the person you bought that from definitely just scammed you. Because if they did take the time to try to flash the retail firmware then they knew it wouldn't work on att to begin with. Best you can do is either flash the proper firmware on it and activate it on sprint prepay or boost ( which tbh there both better than att despite what sprint has said about there own network lately) or you got a WiFi device. actually. Do you know the device model like mine for example is the xt1922-7 which is for sprint/boost.
It is the xt1922-7. There is no bloatware from boost either

Well either way the best you can do is get it activated on Sprint and or boost Mobile. It won't work on att.
My G6 Play is disconnecting Bluetooth all the time.
