Exynos s10+ does not get 4g in USA on at&t - Samsung Galaxy S10+ Questions & Answers

Has anyone else experienced similar issues? I had the same problem this summer but then it started working. This time it doesn't work. Using an at&t prepaid sim.
Have reset network settings, tried some different apn settings, and put the sim in tray #2. Nothing works still only get H+.
I called at&t and they said my phone is registered as a gsm phone, and does not come up as an S10+.
Does anyone have a solution.
Thanks!

AT&T is like that if you're not using their branded phone you don't get their LTE speeds but just regular 4G. Even the rep says your phone is recognized as a GSM phone, i have the U1 International unlocked s10+ on Verizon and i have LTE+ find someone with tmobile or verizon service try their sim card i'm sure you'll have LTE on their network

AT&T is horrible with BYOD, this is well known.
If you gave AT&T your EMEI number on your account for your current device it will not be recognized. You have to go into AT&T, find the branded S10+ model for AT&T, grab the EMEI off of that one and have them put it onto your account. You can not ever give AT&T the EMEI number from a BYOD, it will not work properly.
This is one of the reasons I left AT&T years ago. And you can forget about using Wifi calling or VoLTE, it's locked only to their devices.

[Q] Verizon's Galaxy Note 3 technical and general disadvantage?

Hello,
I am considering buying this phone from Verizon. I have been looking at the phone spec, and found that its technical model is SM-N900V. Is it inferior to the international model N9005 in anyway?
Since I travel a lot, will the difference in the network band prevent me from using this phone in certain countries? Can this problem be solved by rooting and installing custom rom/software?
Thank you!
I don't know what the complete differences are. However I do know it's an unlocked phone and can be used with other Sims.
I have a ATT phone and switch the Sims out on a regular basis.
You shouldn't have any problems traveling with this phone.

No problem at all. Just change the apn settings after you insert the sim and you are good to go.

Really? SO since we are in a Verizon thread, I just want to make sure. If we bought the retail Verizon Note 3 and have a Verizon 4g SIM in it, we can remove that, put in a ATT SIM, change the APN settings, and it will work on ATT network? Calls and Data?

Correct. hspa but not LTE I haven't seen LTE yet but then again I haven't tried an ATT LTE apn either. I believe LTE is on a different band anyway.
But it absolutely gives people in my contacts the impression that I'm calling or texting from my ATT phone. It's sweet.

Thank you for your reply. This definitely make me feel a bit better if I need to change carrier in the future.
In the mean time, can anyone here with technical knowledge tell me if there is any disadvantage in choosing Verizon's N900V over N9005? Especially for using them outside the US?
Thanks!

Can you activate a verizon s5 on tmobile?

the title says it, i kind of want to do this, maybe not for that long, most likely it would be temporary.

No. Google it and you will find that Verizon and tmobile networks are different. Verizon is CDMA and tmobile is GSM. Or something like that.

If you are able to use other carrier phones and just pop a Sim card in and your good to go, then in the future can I buy a variant of the phone I want with an unlocked bootloader and be rooted with no issues?

Nope, i'm actually surprised that Verizon didn't lock the phone if what the above poster said is true. The bootloader isn't what you need unlocked to move from carrier to carrier. Phones with sim cards are generally GSM and phones without sim cards are generally CDMA. GSM phones are normally locked to the specific carrier that you bought it from. CDMA phones are not usually taken on any other networks unless you are moving to a network like cricket which takes what it can get

As he said, Verizon 4G phones are all sim unlocked. Phones like this and the Note 2, which I just came from, have the CDMA and GSM bands. It is just as simple as putting in the SIM, change the APN, and be working. That said, the Note 2 could not get a 4G GSM signal only HSPA+ because of the bands it supported. I haven't checked the S5 yet, but I do believe I have seen that it does support some of the 4G GSM bands.
You are right about the CDMA part which is why it wouldn't be wise to buy, say a Sprint S5, and then come to Verizon because it does not support any CDMA bands.
so you guys can confirm that it is sim unlocked?
They always are. All Verizon Wireless 4G phones are SIM unlocked.

Bare with me if this seems like an absolutely stupid question.
When I travel I have a GSM HTC One S that I pop in a pre-paid SIM to use (say, 3 in Ireland). I believe this was a T-Mobile phone previously that I carrier unlocked. If I have a Verizon CDMA S5, I could pop in the 3 SIM and be able to use it (maybe not 4G depending on the bands) provided I updated the APN information?

Correct. I used my Note 2 in multiple European countries, lastly in Rome where it was stolen. Take your Verizon sim out at the airport, put the new one in, change APN, and voila.
(carriers I have tested with - Orange, Vodafone(multiple places), 3, Rogers in Canada)
Your S5 on Verizon isn't solely CDMA. If you look up any website with the bands it supports, you will see the GSM bands.

More than welcome. And here is the link so you can check the bands when looking at foreign carriers.
http://www.phonescoop.com/phones/phone.php?p=4408
And even without 4G, it is still plenty fast enough to use the internet, google maps, and stream music.
What if you canceled your service and went to tmobile. Would it still work?

Looks like the One S and S5 share the same GSM bands... I'll definitely have to try it out. I know my 3 SIM works here in the US too on the phone. Thanks again, really helpful.

That wasn't the question. The question, as posed, was would it work? It absolutely will work with speeds up to HSPA+.

VZW CDMA Compatability?

All,
It seems that the only way to get the XPE working on the Verizon network is to use an already activated SIM.
If I'm not mistaken, this is only for the LTE portion of the radio (since LTE is a GSM derivation).
To activate a phone on the CDMA network, I believe its IMEI has to be whitelisted.
So, my question is, can this phone use Verizon's CDMA network?
This is important because, while I do get some LTE service at work, the CDMA repeater network typically picks up my phone so that I can receive calls.
Thanks!
CDMA works fine. I don't get LTE at home, and my MXP works fine there.

Great! So nothing more than a SIM swap is needed for CDMA activation?

Easiest way definetly is sim swap. That being said. Being that i wanted a fresh sim. Went to store. Official vzw. All that needs to be done
If you don't have a activated nano or want to cut your micro. Go to store and let them know you wish to activate new MXP. Have them call level 2 tech and they can take care of it pretty quickly. Activated in hand. Or call #202 and explain samething and they will send it. Either way mine is activated and everything works great.

I ran into trouble with Verizon activating my device. Apparently the IMEI wasn't white listed yet.
What I had them do is use and already activated S6 on my account (wifes device). To issue a nano sim. Then plugged into my device and that got it working.
Really not impressed with Verizon not having the devices white listed already. Not sure if it's because mine is custom (64gb/ leather). Either way, I'm activated.
Does tethering work fine for those of us on the UDP?

I had LTE once I got a nano sim. They couldn't issue me a nano sim. I'm coming from a galaxy s4 so needed to get a nano sim. Took almost 1.5 hours, but this was the employee calling someone and trying to find a way for a while. Then after all that I suggested using wifes device imei (which is on same account and takes nano sim). Which that process took maybe 10min tops and plugged the nano sim in and worked instantly. On my account shows my device as "non Verizon device". Didn't even know it is the moto x pure

They used her devices imei to issue me a sim. They can't just give you a sim. Need an imei to assign it. They won't do a random imei or one off another account. Then they used a sim that was assigned the imei of my wife's device. Then the sim updated itself with my devices imei and everything.

Verizon Use

T-MOBILE S7 Edge works on Verizon, ATT with unlocked Sim card! I also have LTE on All 3 Networks.
First question is how did you get your phone unlocked? I thought tmobile made you wait 45 days before they would unlock the phone

A lot of times if the phone is paid off, it'll unlock as long as it meets 1 requirement.

Verizon uses a lte sim card for data only. There will not be(shouldnt be anyway) any call support because the 935t does not have cdma, unless verizon is using different bands on newer devices like tmobile(band 12 - 700a)

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel 
 @T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.
