Just bought an unlocked SM-G960U1 from Samsung.com. I used my active SIM card from the old Moto G4 on the S9 and it didn't work. Checked IMEI with Verizon and it said the phone should work perfectly with their network. I talked to tech service by phone and they told me to look for LTE/CDMA in Settings but I only have LTE/3G/2G and such. in settings. What is wrong with the phone? Is it a real unlocked one or they shipped me a wrong model? Please help. Thanks.
Reset the APN settings
then reboot the phone
and make sure you have store bought sim, they do update SIM models and sometimes it can matter.

Thanks for answering. I reset all APNs to default and reboot but it didn't work. It seems the phone does have any setting related to CDMA network.
That phone is perfect for Tmobile and Metro PCS ...
Is Verizon using GSM type phones ?

Yep there is definitely something wrong. Maybe I missed it but I don't see where you mentioned getting a new sim. The best option would be going into a Verizon store and getting them to put in a new sim. If that isn't possible get them to send you a new sim.

Thanks for the reply. I am using my existing sim card which was purchased two years ago. I will visit a Verizon shop and see if a new sim can do the trick.
New sim card is the solution
Thanks all. A new sim card from Verizon activated the CDMA connection of the new G960U1. I am a happy S9 user now.

Does your model number change to SM-G960U, after activation with a Verizon SIM or does your ABOUT PHONE section list your S9 as an SM-G960U1?

Im new to this phone
So the original carrier is Claro PR. I have succesfully unlocked the phone cause im using AT&T SIM on it and it has signal and all but it wont make/recieve calls, nor text and wont go on the internet.
Anyone have had this happen before on unlocked phone? I was thinking on rootinh it and throwing a AT&T rom to see if it fixes it but im asking first before trying anything that can brick it
Did you unlock it using the free method or by a code?
For data, did you check the APN settings? Under network preferences, did you select auto? Are you sure the SIM is registered on the network?

The phone is unlocked.
When I put the sim card in, in both global and GSM mode, I get an error of an invalid sim and it won't let me edit the GSM settings or apn.
Has anyone done this? I just need a phone for the time being. I'm using the sim card in a different phone to type and post this, so I know the sim card is good and active.
Any ideas help? Phone is stock 2.3.4
Thank you in advance.

Alright, sounds like it should be gsm unlocked. Are you sure the cricket sim is GSM? I thought cricket was cdma but I might be wrong. If you can, try a tmo or att sim in the phone and see if you get signal. Also next time can you quote me so I can see your reply? Thanks.

Cricket is owned by ATT, I think they phased out CDMA in 2014 or 2015. They use all ATT towers now.

Just try to RUU to stock and factory reset. Sometimes you need to wipe everything after entering the code so the phone will autodownload the apn settings.
Hello, I'm wondering if anyone has tried this. Obviously, the bootloader would need to be unlocked.
It works but doesn't. You'll still be locked to Sprint and the T-Mobile ROM will see that and you won't get service until you unlock the SIM. Other than that, it seemed okay when I tested it. Only tried it for a quick 15 minute boot though... Tested my flat mate's T-Mobile sim and my Sprint sim. Both wouldn't work.
Actually, I forgot to mention that Sprint has already SIM unlocked my phone. Knowing that, I could in theory at least flash the T-Mobile firmware and then with a TMobile sim get Tmobile wifi calling and VoLTE? Also would the phone then automatically get Tmobile software updates?

I wouldn't know. It's worth a try. You won't brick your phone. If it doesn't work, the switch back to Sprint firmware is just another flash all away.

I may do so. The only risk is that I'd have to open up a new T Mobile account to fully test, and then I'd be scrambling (and out of pocket) if I couldn't get the tmobile flashed sprint phone to work. Do you have a link for the T Mobile and Sprint firmware?

That thread has all official Oreo flash-all
So - this is my 1st Dual-SIM phone, and I'm very happy to get away from having to carry 2 different phones (personal on T-Mobile; work on AT&T - in the USA). I thought that everything had been working correctly - until I was away from my Wi-Fi signal. If I have SIM1 selected for data (T-Mobile), everything is fine. If I select SIM2 - I get nothing. It always shows 3G for AT&T even though I'm in a very strong 4G area for AT&T.
I've been through the Access Point Names settings for AT&T and they matched what I found on AT&T's web site. I even duplicated them with a new name to make sure that they were correct - still nothing. I've played around with which slot the SIM card was in as well as only installing one at a time (just AT&T in SIM1, just AT&T in SIM2, etc.) rebooting the phone each time - still no luck.
Hoping for an assist or "things to try" from the community as I don't expect much help from AT&T on an unlocked phones. Any help is very much appreciated!
Thanks!

Welcome to the DS family. Does SIM card manager show 4G/3G/2G enabled for both SIM's? On my older Note 8 4G wasn't supported simultaneously so you had to manually switch the 2nd SIM to 4G but on my Note 10+ this limitation doesn't exist but still worth checking.

That would've been too easy. Do you observe the same behavior if you swap the SIM card positions? Also what if you put in just the AT&T SIM by itself (i.e. does it ever get 4G in either slot)?

I've tried both slots with just the AT&T SIM - never get data and never anything but 3G. Strange thing is calls and texts go through...
Hmm, that sounds like it's missing an LTE band it needs to get 4G with AT&T. I don't have an AT&T SIM hand to test with but for the non-US Samsung phones don't have full support for the frequency bands US carriers use (I'm assuming you have an intl phone so correct if wrong.).
I have the dual SIM and get LTE on ATT. I reckon you need to contact ATT and tell them you are using a note 10+ and need LTE enabled.

Spent 2 hours on the phone with them last night. They had me set up the Access Point names over & over - no luck. They suggested I buy an AT&T branded phone. Big help...
I once came from another device to another device and had the wrong kind of sim for 4G/LTE. Or maybe the sim is damaged, or it's just registered wrong.
So: try Hard reset the device AND get a replacement sim card from ATT (can get them at the store and don't let them sucker you into paying for it). Perhaps that will do it.
Came across the post below - I do have an old AT&T SIM card (6 or 7 years?). Looks like an Android 9 update at some point caused issues with older AT&T SIM cards. I'm heading out to get a new SIM from AT&T tonight... Thanks for the attempts at helping - I'll update tonight and let you know how it goes. May be in for a fight - it's a corporate phone and I'm not authorized on the account...

So - I was able to get it working. I had been using the same SIM card for 6+ years. However, getting a new one didn't fix the issue.
They said that the IMEI number wasn't coming up as a valid number. I had a One Plus 7 Pro laying around, so I had them register the new SIM card to that phone, and it magically started working (the old Sim didn't work in it, either). After getting that working, I just moved the SIM to the Note 10+, and haven't had any issues, since.

Hi guys,
My Samsung Note 10+ stopped making receiving calls about two weeks ago.
I have no option for VoLTE if that was the case; I updated my firmware to the last available (Android 12). I called customer service, and they did their "magic" with my IMEI and ID e t. c. I also went to their office, and they said they couldn't help me, but they have customers with the same issues with non-att phones.
Any solutions?
Thank you!
It's whitelisted.

Was this originally an ATT phone?
No, originally Samsung US version, unlocked.
I have a N975U1 and a new N975U. These are both 4G only variants, no 5G*.
The N976U however is whitelisted by AT&T and should work.
I haven't fully configured the unlocked variant so after reading this thread I was wondering what it do. It hasn't been booted since the switch.
Slammed it the sim card and booted; it's working the same as it's sister.
Try clearing the system cache.
Network reset.
Reset on AT&T's side.
*5G Versions: SM-N976F (Global); SM-N976U (USA); SM-N976N (South Korea)
Thank you. My version is the US version. All those things are done. I think I will change the carrier. ATT is just doing nothing.

Something is misconfigured.
It may be the new sim card or ithe sim card may be damaged; install a new one yourself and handle it like a stick of ram, it's ESD sensitive.
Talk to Advance tech support at AT&T, get someone that knows what they're doing... may take a few tries.
Also clear the data in the sim toolkit app in addition to what I already suggested.
Try a hard reboot as well.

On my unlocked new N10+ variant all I did to set it up was slam in the sim card from my other AT&T N10+. I didn't touch any settings on it.

After reading all of this, the only thing I have seen in regards to ATT not making calls is with WIFI calling if it does not have the carrier bloat.
You may have fun trying to find the user data file for ATT to flash for N976U.
If you could, load the carrier bloat U package and see if it resolves the issue.
The only other thing I have seen is when ATT deems a phone incompatible, they just suspend the SIM card and make it inactive. If the phone is whitelisted it shouldn't do this.
The best thing would be to go with someone like T-Mobile who won't mess with your SIM etc.
