I am 420 friendly but I dont smoke. I didn't root my phone. I honestly dont even see a reason to do it either but you can find anything in here or youtube. OP has made phones to be unlocked easy but OP3T has DRM key verification which locks you from modifying system/data in TWRP recovery but of course there are some tips and tricks on how to do it without pain in the '@ss

Im only getting 3g!

I just got this beautiful phone(one plus 3T) and I come to find out I cannot get 4g speeds at all only 3g. I am also on Tmobile and in New York. I spoke with Tech support from Tmo and they are trying to say the phone is not 4gLTE capable which we all know is a joke. One plus support says its definitely an issue with the APN but they(t mobile) need to give me support with that. If I pop my sim card back in my Nexus 5 of course I am back on 4gLTE no issues. At this point One plus wants to remote into my machine and do a wipe of my phone and install a newer OS but Im not crazy about that idea. I tried with the first tmobile tech to add a new APN but it didnt work out. I was still getting the "H" icon on the 3T status bar. Any ideas? At this point I am almost willing to return the phone to ebay but they might bang me with a 20% restocking fee which I do NOT want to pay but it seems to be for sure its a carrier issue. UGH.

please help

can someone please help walk me through this? I am not very knowledgeable with all this stuff. I hear about OTA fix that might work?

phone is Verizon Galaxy S5

I just ported my number to T-mobile and got a T-mobile SIM card in it. I guess phone was post some 2015 law of being unlocked so it seemed to accepted to SIM card in store.

I am now getting very slow hotspot AND directly to phone in small Colorado town, Lamar. Seems to work better in Denver, but not fantastic. Lamar is supposed to have good coverage. I am getting a few bars strength and H+

I am mentally exhausted reading fix threads dating back to around Thanksgiving 2016 on multiple forums.

It seems some benefited from "OTA fix"? Do I need to cancel T-mobile and go back to Verizon? Get new phone through T-mobile?

as far as searching for updates on this forum, do I type in S5 Verizon or S5 T-mobile?
[OnePlus 3T Questions & Answers] Frankenscript:
First step would be to post in a forum dedicated to your Galaxy phone not a One plus forum, but the short answer is probably that your Verizon phone doesn't have the radio configuration for optimum use on T-mo's GSM based network. Verizon uses CDMA technology. So, sell that phone and get a T-Mo variant. Or better, get a OnePlus 3T and join us here! Good luck.
[OnePlus 3T Questions & Answers] mx_599:
I wouldn't be opposed to getting a new device. Who makes onePlus 3t? I am trying to find website for it...
[OnePlus 3T Questions & Answers] SpasilliumNexus:
OnePlus makes the phones. http://oneplus.net
[OnePlus 3T Questions & Answers] Frankenscript:
To add to what [MENTION=5083335]SpasilliumNexus[/MENTION] said, the OnePlus 3T (the focus of this forum) is last year's model and was discontinued back in May or June. It was replaced with the OnePlus 5. However, the 3T is still available from various outlets, and many of us, including myself, bought one used at swappa.com. Swappa is a great place to buy used phones, because they check the IMEI to ensure the phone isn't blacklisted. Buy from a seller with good ratings and you will be golden.

If you buy a OnePlus device for use in the US, be sure to get the right model, since models made for China or EU won't work properly here; basically the same "wrong bands supported" issue you are experiencing with your Verizon phone. For the 3T, the model number is A3000.

Good luck whatever you decide to do.
[OnePlus 3T Questions & Answers] mx_599:
oh man, I feel like an idiot! I just spent hours backing up my phone, going through kies, then smart switch, then CC++++ freaking updates, countless errors, etc etc. I thought I could put the Oxygen OS onto my S5. I didn't know about one+

So is one+ like independent of the major cell carriers? I thought main players like Samsung, apple, lg, Motorola, htc were only choices? or is One+ sold at stores and I never noticed? so you get One plus and choose carrier? any preference to carrier? just dependent on location?

no drawback to just getting the one+ 5? or is 3t more desirable?

and in the end, are people getting good tmobile speeds now on One+ phones???

Seems like tmobile has best unlimited plans, no? I was hoping to make it work, not opposed to new device.

so no way for a guy like me to put new OS on my verizon S5? just want to make sure before I get new device
[OnePlus 3T Questions & Answers] Frankenscript:
Right. OnePlus (One+) is just another manufacturer. They sell internationally, including US. Not affiliated with the carriers here. The A3000 3T and whichever model of 5 is intended for US work great on the GSM carriers in the US, like T-Mo and ATT.

Putting a new OS on your S5 wouldn't help with the radio mismatch. Also, Verizon and ATT tend to lock down the bootloaders on the devices, severely limiting what can be done. I had an S4 years ago, and swapped out my ATT version of S4 (locked bootloader, only allowed Touchwiz ROMs... yuk ...) for a T-Mo version of the S4, which was not bootloader locked and allowed AOSP and the like.

The OnePlus phones are designed for people who like to play with stuff and do custom ROMs.

Come on in, the water's fine. If you consider the OnePlus 5, read various reviews. Some people are bothered by the "jelly scrolling" reported by some people. The display is actually designed to be in upside down and some people notice an optical effect caused by this. I haven't seen one personally so can't comment. For now I decided to hold off on the 5 and trade up from my LG G3 to a OnePlus 3T. Couldn't be happier!
[OnePlus 3T Questions & Answers] mx_599:
how do you know what you're getting with the OnePlus 3t? did you find a good source? can you still get new old stock? what did you pay? I would hate to get a piece of crap
[OnePlus 3T Questions & Answers] Frankenscript:
Check out swappa.com. I didn't find new old stock anywhere at reasonable price so I went for used on Swappa. You see picture of the phone, description, etc. before buying and can ask questions of the seller if you need more detail. I got a mint 3T with extra cases and stuff for $370.

Probably we should let this threat return to it's original purpose. If you need more info, start a new thread! Hit thanks if I've helped you, and good luck.:)
[OnePlus 3T Questions & Answers] mx_599:
okay, yeah sorry, didn't mean to hijack thread.

but actually, it kinda is pertinent because I think I am going to buy one of these and I have tmobile :)

but before I buy one, I need to know if things are okay for people now? I am having a hard time confirming this.

my speeds are so slow, some pages do not load. If I am using the phone a lot as a "hotspot", shouldn't I at least be able to expect HD stream type speeds? My signal looks like it should be good enough.

last question, I just got this SIM t-mobile card in my S5...if I get this One+3t unlocked, I should basically be able to take SIM out and stick in new phone? how hard is it from there? Are there steps I can look for here to walk you through set-up?

thank much
[OnePlus 3T Questions & Answers] SpasilliumNexus:
I'm happy with T-Mobile on the OnePlus 3T. A screenshot of current LTE speeds I'm getting at home attached. Results may vary depending on your location. And yes, I can stream HD when tethering too.

For the SIM card, the S5 uses a micro-SIM. You will need to either get a nano-SIM from a T-Mobile store (for free maybe), or buy a new one cheap from somewhere like eBay for like $1, then call T-Mobile and tell them you want to transfer your service to that new SIM card. They will want your phone number, verification of the account, and numbers printed on the new SIM card.

After that, pop in the SIM and it's ready to use. The phone sets up the APN to use the current LTE APN automatically.

IMEI bug

AT&T chat rep did a great job of cleaning up the mess that the in-store AT&T rep made of my account. Found a bug in the OnePlus ROM at the same time. It looks like under About -->Status --> IMEI the OS only shows the first 14 of the 15 character IMEI. That is most likely the issue I had in store. Chat agent had issues with the IMEI I provided and stated it should be 15 characters. I checked the sticker that came with the phone and sure enough. Sounds like OnePlus needs to fix this in the ROM to display all 15 IMEI characters.
[OnePlus 3T Questions & Answers] worldsoutro:
This is concerning
[OnePlus 3T Questions & Answers] someone0:
from the look of the screenshot, both the upstream and ping time are in range of each other, they are both definitely on LTE, but my guess is that OP3T may be missing one of the LTE channel that T-Mobile use.
[OnePlus 3T Questions & Answers] kirdroid:
Yeah that's what it looks like.
[OnePlus 3T Questions & Answers] Xdpker06:
My OP3T shows all 15 IMEI characters in the About--->Status--->IMEI information section

The OP3T definitely has all the LTE channels that T-mobile use. In my screenshots of LTE discovery in the OP, you can see it switching from band 4 to band 12. The problem is with 4G+ or Carrier Aggregation. The phone tries to use both bands at the same time to increase speed. This is when the speeds drop down to very low numbers. Instead of speeding up, it is slowing way down for some reason.
[OnePlus 3T Questions & Answers] GiSS88:
Hoping this is a software issue, as all specifications show it as working perfectly on T-Mobile's bands. Would definitely be an issue for me if I'm not getting decent speeds. Currently getting 30/12 in South Jersey, which is fine if it's solid and not jumping around.
[OnePlus 3T Questions & Answers] Xdpker06:
Yeah, that's the result of your Pixel using carrier aggregation correctly and the OP3T not.

Does your phone jump between 4G and 4G+. If so, can you do a speedtest and post your results?
[OnePlus 3T Questions & Answers] hachamacha:
Despite my not knowing much about the 3t or the pixel - xl, I happened across a thread that does seem related. Maybe there's some info in it that could be of use. Good luck,

That sucks. My 3T is running 4G+/LTE on att. No edits or att store visit required. I just popped Sim card out of op2 and right in OP3T
[OnePlus 3T Questions & Answers] Xdpker06:
I saw that and I don't believe that's the issue. The problem isn't that I cannot connect to any LTE bands. It's that when the phone tries to use multiple bands at the same time, it fails.
[OnePlus 3T Questions & Answers] robdam1001:

I won't get it until Monday, I'll do some tests when I can.
[OnePlus 3T Questions & Answers] Xdpker06:
I'm guessing you're on ATT? Please don't say T mobile haha. Yeah when I'm on 4G+, speeds drop to ~4 Mbps.
[OnePlus 3T Questions & Answers] robdam1001:
Yes, att. That sucks. For your sake, I hope OP or Tmobile improves the speed.
[OnePlus 3T Questions & Answers] cousinit99:
I'm on AT&T. Right now, I'm not getting any mobile data when using the "NXTGENPHONE" APN. As soon as I switch to the "Phone" APN though, it connects at HSPA+ instantly. No LTE yet, unfortunately. I'm hoping it's just an LTE provisioning issue. I was using an n900 for the past three years, which is 3G only... :eek:
[OnePlus 3T Questions & Answers] kirdroid:
Wonder if they test out the phones in their labs, they are selling directly in North America so I assume they would have tested it on the compatible networks. Looks like something that could have been caught easily with a simple test. Not sure if the have teams here in the north America to do the local testing and other fine details. Or they just let us users report issues and fix them hoping it fixes in the next update?
[OnePlus 3T Questions & Answers] unknown00:
same problem here with t-mobile. so what's the fix :( ?

I'm on AT&T, this is roughly what I see as well.

Perhaps, the question is does OP3 does the same thing or not or T-Mo?
[OnePlus 3T Questions & Answers] Jeff_in_LA:
I just got my phone and I noticed with WIFI the speeds are slower then they should be.

My old Nexus 6 gets 130mps and the 3T sitting right next to it gets around 35.

Interesting...
[OnePlus 3T Questions & Answers] someone0:
OP3/3T doesn't have the same MIMO antenna as the one in Nexus/Pixel. While the SoC on the OP3/3T does support MIMO, the rest of the hardware do not. Still it should definitely be more than 35. I know it can go to atleast 70mbps leaving my house. I gonna try iperf and see what it look like locally.
[OnePlus 3T Questions & Answers] Xdpker06:
I feel like I'm wasting my time. I just got off the phone with Oneplus support and they're not even acknowledging it's a problem, blamed it on the low signal in my area. Such BS, if you're getting 45 mbps on band 4, logically you'd expect it to go up or stay the same when aggregating right?? Not drop down to close to zero. Am I totally wrong here?!? Mb I'll tweet at Carl Pei and Oneplus or something.
[OnePlus 3T Questions & Answers] jtfan:
Thanks for your work OP. Whether they will acknowledge the issue, your efforts are not going unnoticed. Many like myself are reading this thread basing our purchase decisions on the outcome and response of oneplus support.

I'm in suburban Indiana where T-Mobile is pretty bad. My old Galaxy phone had little to no LTE but now I'm getting LTE (Band 12) at about 8-12mbps and sometimes even CA LTE with Band 4 and that boosts me up to 8-20mbps. My upload does act a little weird when CA is on and 4G+ shows. Not any big issues to report though.
[OnePlus 3T Questions & Answers] Xdpker06:
They aren't even acknowledging it's a problem when I talked to their level 1 techs support on chat and over the phone. I'm going to call T Mobile to see if it's something on their end and then mb tweet CarlPei + Oneplus and/or blast them on Facebook. I encourage all of you to do the same.

Odd, getting way better speeds off my router from the OP3T vs my pixel xl. I'll test cell networks tomorrow.
[OnePlus 3T Questions & Answers] trentonite:
Same deal here. Sitting on 4G when not running a speed test. Upon starting a test you see the icon go to 4G+ and the cell network switch to LTE_CA. Once it's done it switches back to 4G. Best Speedtest thus far was 13 down, 1 up.
[OnePlus 3T Questions & Answers] Xdpker06:
Are you on T mobile or ATT? Seems like this issue is affecting mostly T mobile users.
[OnePlus 3T Questions & Answers] trentonite:
T-Mobile. On idle the icon shows as 4G but any time there is something loading or downloading it flips to 4G+ and is noticeably slower.

Attached were the speed test results. Managed to get the upload slightly better but still nowhere near my old S5 sitting next to me. I played around with the network I was connected to and results for the most part were the same.

I have same issue in Toronto, Canada with Rogers Network. All I see is 4G and 4G+. I assume 4G+=LTE. The maximum speed I am getting under 4G+ is 32gb.
[OnePlus 3T Questions & Answers] Xdpker06:
I could not find an option to turn off Carrier Aggregation, only to turn off 4G completely and use 3G/2G. In any case, that would not be an ideal long term solution. We shouldn't have to handicap our phones because Oneplus can't figure it out.

I think you are fine if you are getting 32 Mbps under 4G+. I believe this is a issue isolated to T Mobile users in the U.S. I don't think ATT users are having problems with 4G+ carrier aggregation either.

What is this Rogers network?

I just spent 2.5hrs in a T-Mobile store. I tested the employee's sim in my 3T for a little and it does indeed go between 4G+ and 4G every couple seconds. They still got me to buy into their service for $60 unlimited data but I'm praying for OnePlus fix. The way it is now, I'm reaching 6mbps down, roughly the same mbps up on T-Mo. With my Galaxy s5 VZW edge to edge with the 3T, the s5 got 20+mbps down, similar up. (edit: and the phones had similar bars, nearly full)

Anyone else the same?
[OnePlus 3T Questions & Answers] Xdpker06:
Rogers is a wireless carrier in Canada. Yeah it seems like you're having the same issues as the rest of us on T Mobile US. If you can, try getting a speedtest on 4G and one on 4G+. They should be drastically different.
