Carrier detects as a 3G device - OnePlus 6T Questions & Answers

Hi guys,
My OP 6T is being recognized as a 3G device hence loosing all the benefits given by my career for 4G devices.
The model number is A6010. Any solutions for this?
My sim is 4G and I tried both sim trays. But none of them works.

Which carrier are you on?

[Q] Galaxy S5 G900f LTE support

Hi, I am using Samsung Galaxy S5 G900f. I was wondering if my phone supports LTE/4G ? My network opperator still doesn't have 4G network, that is confirmed info, BUT does my phone support it? For example if I went somewhere where there is 4G support and insert that SIM card (I unlocked my phone with codes). I did get the S5 through my carrier so is it also possible that since my carrier does not support 4G they could have ordered S5 without LTE/4G since it wouldn't have point to have it if the network doesn't support it? Is there a way I could check if the device itself has support for LTE? I network modes I do not have LTE.
My network operator: mt:s Serbia
Country: Serbia
This is my first post to XDA EVER and virst post on any forum in a few years probably so excuse me if I made some mistakes and sorry, also sorry for my bad english.
Help?

The G900F version is the internatioal LTE variant, so yes, it supports 4G/LTE. Inserting a SIM with a 4G plan will work.
If you can't see/select LTE mode it may be because you got a specific carrier rom. Changing your rom to an open country on should enable it once more.
Thank you! That's a relief. Won't change rom yet because of warranty and no LTE here either way but good to know.
Thank you again.

Yes, it supports LTE.
You're not seeing the LTE option under network modes because the option is disabled for your Carrier, thus it will not show up when you have your SIM inserted.
If your carrier does not have LTE yet, then it is turned off in the firmware by Samsung for your carrier SIM. If you were to insert a SIM from a carrier that has LTE, you may be able to use it. (Depending on how long they've had LTE and if it was enabled. Each carrier has to be enabled in a list.)
Enabling it is done via firmware update.

Carrier compatibility.

Hello! My question I've nexus 6p 32gb Unlocked purchased from New Jersey.. But I'll be using it in India. So will it be compatible with all the carriers present here?
Thanks!
Depends what kind of bands your carriers use in India

Thanks for replying. ..Does the unlocked version contain both the American and Global bands? Coz I see there are few bands missing in American version which are there in global and vice versa.
Thanks!
No it does not, the American version is missing the global bands

Okk..thanks...Got my Jio sim...Signal looks solid...for the first few minutes... but then it started fluctuating very much .. maybe changing bands every now and then coz jio operates on 3 bands 3,5and40. But as 40 is not present in American model, it switches between band 3(1800) and 5(850)very frequently...I got to know this from an app... So should I lock the band on 3/5 any of them(from network signal guru app) ? Will it stop fluctuating then?
Thanks!
What's the name of the app you use?

Thanks... There are few issues I'm facing.... Got two more Sims voda and bsnl ... Voda gives no signal as soon as I insert it and bsnl is working well but most of the times I cannot place/get calls.... And according to that link these two are fully compatible with American model..:crying:
I've noticed in bsnl that as soon as I toggle the mobile data ON, then I can get/make calls but as soon as I put if Off, again problem starts.

Carrier Aggregation on S7 Edge Exynos Unlocked version (SM-G935F)

I recently bought an S7 edge unlocked SM-G935F Exynos version. I am currently using it on T-Mobile and have VoLTE and WiFi calling after flashing the TMobile CSC. However, I cannot get the right bands working for Carrier Aggregation. When I go into ServiceMode, the only CA combinations showing are :
7C(A)
7A-7A(A-n)
There's nothing about bands 2, 4, or 12 that T-Mobile uses. I've tried using various ROMs and CSC tools to try to get the correct bands for CA to show up but nothing. Does anyone have any insight on how to get this enabled? I saw something a year old on reddit but the details were a little vague.

Tried what was mentioned in that article. It didn't work. No idea why the CA is also only showing Band 7 when T-Mobile only uses 2,4,12.
What's even more strange... I brought the phone overseas to Taiwan last week, popped in a Chunghwa Telecom SIM, and all CA band combos for LTE bands 3,7,8,28 showed up without any issues and the phone was lightning fast.

Check with another US SIM card and see if the T-Mobile card's behavior or the Taiwanese one is replicated.
Try with a Metro, Cricket or AT&T card.
Also, on which network was this phone previously used? Because I am not sure if I'm right but if it was used with a CDMA network, it might not work with GSM US networks (not sure about it tho).

I know the previous owner on Swappa said that he used the phone with Cricket, but no clue if he checked if CA was working. Also I thought the Exynos varieties didn’t have any support for CDMA.

Is LG G6 H870 Eropean model region locked?

Just as the title says, is the H870 region locked, can I use non-european sim cards?
To be more specific, can I use Japanese sim card?
Phones are not region locked. The real question is does the phone support the bands available in the region that you want to use it.
Hey, thanks for clarification, I just heard something about lg blocking foreign sim cards, but I couldn't find anything about it. Also, as far as I know, bands shouldn't be of any problem.

If you got it on contract from a carrier it could be carrier locked. I am on EE UK and my G6 H870 is sim locked to EE.

LG doesn't block anyone's SIM cards. Only carriers lock phones.

Exynos s10+ does not get 4g in USA on at&t

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.
