[question] gsm 3g switch to 4g network - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

Hi Guys, I have a new Samsung galaxy s5 from Sprint SM-G900P.... It's unlocked gsm networks the thing is when i buy mobile network it just work in 3g and i want it to work as 4g lte im from Dominican Republic i use Claro Dominicana Company and my Sim Card is a new technology from the Company and the sim card work for 4g .... How to make the switch? ??

If you're rooted, you could possibly force it with xposed. Dialing ##data# will give you options to adjust. I know I use it for cdma. I don't know if it will show options for GSM tho.

Answer
Hey bro! I have an g900p too here in orange. The thing is that in the stock sprint rom it doesnt have the option to select 4g in our local bands, so you will have to install a custom rom for G900F, rom only, no kernel. For the kernel flash the ktoonsez kernel. The rom i have been using is called xtrosolite or something like that, you can find it in the samsung s5 development forum. When you install it, if you cant enable 4g lte yet, ( im supposing you already have a 4g lte sim card) you will have to unlock the lte bands using qualcomm programs QPTS and a few others, there is a thread for that here in the forums, just look for ''how to unlock lte bands''. I hope it helps you.

AT&T Samsung Skyrocket able to work on Australian Sim card

Hi guys not so sure if I'm posting in the right place but I was wondering if Australian sim card can work with the skyrocket?
Many thanks!
As long as its GSM, and your network is running skyrocket supported frequencies (gsmarena.com > search skyrocket) you should be fine.
Basically, if you have what's called a gsm carrier you're golden.
With that said, your carrier/phone service provider may not have LTE or even 4g (hspa+) capabilities, meaning 3g only.

[Q] Photon q european 4g frequencies

I own a photon q 4g and did the sim mod
i live in the netherlands where the 4g frequencies are at 800mhz,1800mhz and 2600mhz
when i use the *#*#4636#*#* code i can see the different bands you can select but there is no EU setting
but if i look at screenshots of QPST i can see that the frequencies are usable.
Does anyone think it is possible to get the phone working with dutch 4G?
Is it possible to use QPST on a modded phone with cyanogenmod?
Greetings
Mafradon
What you are looking at is the UMTS and GSM Part, not LTE.
So that's nothing that tell you about usable frequencies.
Besides the LTE part of the Photon Q is using the "flashed" SIM-ID (or whatever name it has).
It can't use the SIM-card from the SIM mod.

but you remove the sim ic in the mod you substitute the sim card for the ic dont you?
Afaik the SIM-IC is/was used for GSM and WCDMA only.
LTE, CDMA etc. is using some in the phone flashed entries.
If you can correct me, please do it. I would love to be wrong.
what rom u are using? and what was your base (cspire / sprint) ?
rom
right now i am using the gsm version of cyanogenmod 10.1 the phone was a sprint phone originally.
I would love to now how the phone ties up the customer to the lte network (aka 4G) as all 4g phones over here do that with a sim card not through the system cdma uses. Or am i wrong altogeter and is an american lte network compleatly different as opossed to a european one?

Unlock 4G lte bands verizon M8?

Hi,
I'm using a verizon M8 on a non-verizon network. The Verizon version should support 4G LTE on band 3 and 14 (the hardware should even support 3,4,7,13). My provider supports 4G LTE on band 3 and 7, yet i don't receive 4G.
I'm guessing Verizon locks 4G to their network. Is there any way to unlock my phone so i can use 4G LTE with my provider? (T-mobile NL)
I am willing to do anything. Already reflashed my phone with verizon ROM but that doesn't help obviously because it's not a stock rom..
Thanks!
There is a working solution for the Android:
http://forum.xda-developers.com/verizon-htc-one-m8/general/lte-band-7-2600mhz-finally-guide-t2992523
I think, there IS a way to adopt it to the Windows Phone.
htc m8 for windows verizon
Any news how to activate lte band?
looking for this too. In my country there are 3/20 bends and verizon edition has that band but I cant use 4g

S6 Edge - G925R - US Cellular

I have a rooted S6 edge unlocked for US Cellular (G925R). I see a lot of ROMs here on XDA but moslty for other variants .
Is there a way to safely flash a ROM belonging to different version for the version that I have ? Is there a workaround that can accommodate this ?

I assume the G925R has an unlocked bootloader, which is how you got root.
You should be able to modify the updater-script in a ROM to allow it to flash properly on a G925R (zerolteusc), I guess a ROM for the T-Mobile S6 Edge could be edited to work on a US Cellular.
Don't try it without confirmation from a more experienced member though. I'm just saying, editing the build prop will work, but T-Mobile is a GSM based carrier whereas US Cellular is CDMA, so not sure if the ROMs for the G925T will work on your phone.

Thanks, I will look further. Pardon me if I am asking a silly question but I see an option to choose the preferred network mode as LTE/CDMA or LTE/GSM. Also my device has a SIM card slot so is this device capable of both CDMA and GSM ?Currently I am using a Tmobile SIM in it and I have also tried an AT&T SIM, both worked as I could make calls. I am asking this as I am planning to use this phone outside US and if the device is CDMA only it will not be able to work on the networks outside.

No problem.
Pop in a SIM Card of your choice and you can use the phone on most GSM based carriers even abroad.
You mentioned that AT&T and T-Mobile were working, so you're all set.
Verizon, US Cellular and Sprint devices are CDMA but they have a SIM slot. So they will work with GSM carriers provided they are unlocked.
Oh, and about the network mode, select the right one depending on your network. If you're on a CDMA network, choose LTE/CDMA or if you're on a GSM carrier, choose LTE/GSM.

AT&T LG G3 850 Unlocked - Won't give 4G speed

Hello guys
I tried searching for this problem but got nothing that would help, so am posting here.
Issue:
I recently bought LG G3 from someone. The phone is unlocked to work on all networks (AT&T branding on the rom exists though). I am using it outside of USA and it works fine. However I am unable to get 4G speed on my 4G enabled sim. I tried this sim on other phones, and other sims on mine. It is evident that it's my phone that is not supporting the 4G speed, despite showing the 4G logo up top, when data is enabled.
Things I've checked:
I have checked the bands (1800) that my model support and verified it with my network to confirm that it should run their 4G service.
The phone is not rooted.
The sim is functional and has no lock on it.
Checked with hardware checker apps to confirm that my phones supports these bands.
I am not sure if it should root it, or what. I would really appreciate your guidance on the matter.
you need u-sim and 4g data plan for make 4g work, check if u have all of this.
Hello
Yup, as mentioned in the details, I all of that.
Make sure ure apn is for lte or 4g i got stuck with a old apn from my provider once and only edge speeds
