Galaxy a71 won’t connect to SIM card? Help please! - Samsung Galaxy A71 5G Questions & Answers

I just bought galaxy a71 5g and guy said it was Samsung unlocked. I went ahead and ran it through multiple imei checks even payed ones and it has never been blacklisted and it is indeed unlocked carrier. I put my T-Mobile sim in and all it says is no network connection but about says my phone #. So it’s reading SIM card but no connection. I will post baseband and build number. Does anyone have an idea of what’s going on?

[Q] NOTE 2 - SGH-T889V - Unregistered Sim

Hi all,
I'm having a serious issue with my phone that just recently bought off kijiji, I suspect that my phone could be blacklisted or blocked.
So, heres the issue we, me and my friend went and tested this phone out. Since my sim was too big for the Note 2, my friend tried his and worked fine with WIND. After the person who's selling to me swiped the note 2 and gave to me. Deal done. Ok, once I got home, I cut my sim to size and tested it = invalid sim. Asks for unlocked code, but when i called the guy (person who sold it) he told me originally the phone is factory unlocked and suspected that i may have damaged the pins but wait if i did damage the sim slot pins it would've said NO SIM. Went to the store got it unlocked and still have the same problem. Went to a virgin store gave me a new sim that's actually to size and same problem. After virgin told me that on their records the IEMI # - listed a completely different phone like Galaxy Ace S6802 but the serial number on the phone is registered as a NOTE 2. So that's major red flag. Next, went to Wind, they said their going to charge me to get the phone registered on their networks. But there's the thing the phone worked with Wind sim card but after unlocked NO SIM cards work. I went to the settings of the phone and it supports multi band network so LTE and GSM and all the others should work. Also, when i use my friend's sim it says roaming but still doesn't work.
So, i'm assuming the original person stole the phone and it has been blacklisted and maybe he got some hacked to make it work for himself. By the way i do know where this person lives and i have strong evidences to support my claim against this person and will file a report against him if necessary.
SOOOO...any ideas guys?
Anyone got any input on the topic?

Please Help, I don't know what provider my phone is locked to.

Hello,
I received a phone a few months ago for free from a woman I used to babysit her dogs for. The phone is a Samsung Galaxy S4 and it has the original SIM card in it, but under the about phone, it says Network Unavailable and No SIM card inserted. The lady does not remember where she got the phone from, and I don't know what to do to find out what provider it is locked to or if it even is locked. I live in Texas, and the phone came from Oklahoma. The lady used Pioneer Cellular then right before giving the phone to me, switched to US Cellular. She had the exact same type of phone from both companies. Both was contract as well. Anyone please help me. I want to use it for Straight Talk, cause where I live is a country road and the service is sucky.
If you can root the phone you might be able to unlock it, making the carrier useless. Or you could try to Google the IMEI and see if that yields any results.

Completely lost. Samsung Galaxy S7 bought off eBay for "Verizon" not working.

Completely lost. Samsung Galaxy S7 bought off eBay for "Verizon" not working.
Ok guys I'm completely lost here on what is going on and hopefully someone can help. I've flashed tons of firmware, rooted and unrooted several times.
I bought a Galaxy S7 off eBay. The model number on the back of the phone is SM-G930V, the box says SM-G9300 on the back corner.
I thought it would be good, put my SIM card in it, and it won't recognize it, says "No SIM card - No Network Connection"
So I did and IMEI check, and it comes back:
Brand: Samsung
Phone model: Galaxy S7 G930P
Blacklist status*: CLEAN
So the IMEI is actually coming back as a Sprint IMEI. *#06# come back "Not Registered on Network"
In the about phone settings the IMEI matches the IMEI on the back of the phone.
currently I've flashed the latest Verizon firmware using the Verizon software upgrade assistant.

My main goal here is to get this phone to work on Verizon. Any help is appreciated.
Boot into download (Vol down + home + power) and get the model number from there, can be faked in the OS.
Sounds like it's a different carrier model and is still carrier locked to me.
Yep check download mode for actual model, but if a Verizon SIM isn't working and IMEI says G930P, then try putting a Sprint, Boost or Virgin Mobile SIM in it
You might need to pay to unlock it for Verizon
Download mode shows that is it a G930V, and that is what is on the back of the phone as well.
I'm not sure how if this phone is a G930v and it has all of the IMEI and G930v markings how the IMEI is registered with Sprint.
I used a co-workers SIM FOR some pre-paid plan that works on the sprint network and it did show signal
It has the Verizon OEM ROM on it though, how can I get it on for Verizon? Do I have to flash a sprint ROM or something first?

Strange one, unfortunately flashing different carrier ROMs doesn't switch it over to be open for that carrier, you'd need to SIM unlock it with a paid service, but as it is a G930V it should be working with Verizon SIMs unless someone has somehow modded it for Sprint, not sure if changing the IMEI (Which is not allowed to be discussed here) would do that, no idea
Personally I would give a SIM unlock service a try, or try another Verizon SIM in it in case it just doesn't like yours
Is starting to sound like it was originally a 930V and someone has changed the IMEI to Sprint, and that IMEI is still carrier locked to sprint.
Unless Sprint offers a service where they change other carrier phones onto their service?
bump, anyone?
It might be a damaged device.
Eureka!
So, something is definitely funny with this phone, i hope this can help other people who bought a phone from an eBay seller that might be less than reputable.
The Phone is IDENTICAL to my OEM purchased from the Verizon store S7. literally perfect, but I think it might be "fake". For one, the wireless charging does not work. and for two, the IMEI when checked definitely comes back to a G930P, however on the back of the phone, underneath the glass it clearly says SM-G930V and has the IMEI # engraved that matches the phone, which comes back as a G930P.
That being said, here is what I did to fix it.
I flashed the G930PVPU4APL6 Sprint 6.0.1 ROM
I then used Zx3 box to root the phone
Once rooted, I used ZX3 box to unlock the phone
Then I flashed the VZW-G930VVRU4API3-20161121101036 Verizon 6.0.1 ROM
and boom, it works on Verizon!
I do have another question.
If I go into the phone and do a "Factory Data Reset" will I lose my unlock?
No. It's safe to do a factory reset.
Sounds like a damaged ROM (possibly damaged SIM).
You CAN do a swap to a different firmware, though.
True story - my current S7 had VZW firmware (from the jump); however, the original owner blew up the phone and left oweage on it; therefore, it was "network locked". Basically, I was not supposed to be able to take it anywhere.
How I end-ran the network lock - I put T-Mobile firmware on it. (Permissible - the phone itself has a universal SoC - I downloaded T-M firmware via updato.com, installed it using the current version of Odin, and plopped a T-M SIM from Tracfone into the phone, and migrated it to the T-Mobile side of Tracfone - replacing my VZW-hosted Tracfone handset - a Galaxy Nexus. Absatively legal.) End result - VZW (supposedly) S7, running T-Mobile firmware, on the T-Mobile side of Tracfone - as legal as an American eagle. I have LTE and VoLTE working (in fact, I have it set to use LTE right now, since I'm at home; however, were I too far from a T-M tower, I could use VoLTE (this is, in fact, explicitly supported by T-Mobile as a standard feature for this phone - even for their MVNOs - such as Tracfone)). Not perfect - however, blame the carriers for not following the MVNOs and allowing non-stock firmware; VZW, for example, REQUIRES stock-only firmware on their sold-by phones - their MVNOs don't. Do the other carriers - including AT&T Mobility, T-Mobile, Sprint, etc., have the same policy? I get WHY VZW has that stock-only firmware policy - their-in-house support folks know diddly about third-party firmware - how can they be expected to know anything about all the various sorts of third-party ROMs? MVNOs don't have in-house support folks the way VZW, etc. do -most of them don't have their own retail locations, either. (Tracfone, for example, is JUST starting to deploy branded locations.)

Unlocked note 8 AT&T but no gsm sim works

Hi everyone
I’m kinda puzzled with this note 8 and need some advice. Recently got a note 8 from AT&T and since I was traveling I had it unlocked to use by a third party company ( since att doesn’t unlock until Device payment is complete)
I got the code, unlocked the phone successfully. Before I left USA I put a working T-Mobile sim to test if connectivity, no luck, it doesn’t work, I tried a Verizon sim, nothing works....
Note... this T-Mobile sim and Verizon sim if I put it on a different device it will work...
any reason why this is happening

The phone is not unlocked. Seems like an error happened when you got the unlock code. I'd try again.
Did you use this device on the att network? I mean, do you have it activated?
If you unlocked it by codes and the message after inserting the code is something like "unlock successfull" then your device must accept other GSM SIM cards.
Also, I would recommend you place a 5 min call with your device, with the att sim card and then insert again the tmob card.
What is the message when you insert the tmobile card in this device?
I did the same thing by using a Tmobile SIM during the unlocking process, and it worked on TMobile right after I unlocked it. It sounded like you did not unlock it using a different network SIM but using some other method. I am not sure if that mattered or not.
I then traveled to Asia, and I bought and used a local SIM card with zero issues. The 4G LTE was faster in that country than AT&T... LOL

Can somebody answer a few questions I have?

Hi,
I have a Samsung Galaxy S7 that is listed as a SM-G930P on the back of the phone however when I check the "about phone" section it shows as a SM-G930T. Why would this be? I am assuming due to a firmware flash or something of the like. My question is what would be the advantage if any for doing that? Also when I called T-Mobile they told me the phone has a clean IMEI and is able to be activated. However when I check my IMEI # using their online IMEI checker it states that they do not recognize the IMEI I entered. And last but not least how can I check to see if my phone is unlocked with and without a sim card? One last question the T-Mobile customer service rep told me that if I activate my phone on their network and maintain service on it for 40 days I can unlock my phone myself using their app. Is this correct?
Any assistance answering these questions would be greatly appreciated.
Regards
George

some times phones get repaired and tech could have put 930P back cover, also if you flash 930T firmware it will also change the model,
run your imei here
https://www.t-mobile.com/verifyIMEI.aspx
if its detecting there then its 930t phone, you cant check your phone without sim, you can put Verizon sim or someone else other than Sprint and tmobile to check the unlock, yes you can unlock the phone if you stay with Tmobile stock firmware then you can use builtin app for network unlock if its not unlocked
