My phone is sim unlocked, using viper one rom, i'm always stuck on gsm even though my carrier "ooredoo algeria" supports 3G, i have checked and the cdma network frequencies are well supported on the device, how do make i the phone use 3G.

Have you tried going into *#*#4636#*#* and scrolling to the bottom, and changing the frequency to WCDMA only? Also, if you have a SIM card, your phone is GSM. CDMA phones are always without SIM cards, unless they support 4G (since 4G needs a SIM card to work)
ooredoo dz network mode switch must be Automatic

Hey Abdou, you have to put your network mode on "automatic" and ooredoo's network will choose the right netmode for you
Problem solved

Thank you for the reply, but i already fixed the issue, i was a noob when i asked it and i didn't understand what cdma and gsm meant i thought cdma meant 3G, but now i know that UMTS means 3G haha, and that i am on a gsm network, i figured it out.

Using the Telstra based roms, I can turn 4G/LTE off and my battery easily gets me through the day, with 4G on, I have to recharge by 1pm.
On at&t based roms, there is no way to turn off 4G/LTE when you are in Australia, as all of Telstra's APN's support 4G/LTE, there is no apn you can select which disables 4G/LTE, in the Telstra roms there is an option under settings > Mobile Network which allows you to select 3G only, *#*#4636#*#* forcing to wcdma works but doesn't stick.
is there a mod that could disable the 4G/LTE modem or is this something that needs to be cooked into the ROM?
Maybe I could just kill the 4G/LTE modem "device" via a script in the console?

Get a non LTE enabled simcard, or use hdspa apns and delete the LTE apns, this will disable lte.

Why, especially when the carrier Tel$tra doesnt do non
LTE apns
Stock ROM from this carrier gives the option to just switch it off
Surely this can be cooked into other ROM's
in Australia, all SIM cards from telstra allow for 4G/LTE and all APN's use 4G, the only "odd" sim cards are the iphone ones or the ones that were 2G only, the only way to force LTE to stay off that I am aware of is either using the MIUI rom that doesnt have an 4g/LTE modem driver and so wins by failing, or using a ROM based on the Telstra rom which has an easy switch to turn off 4G/LTE

I'm no ROM developer, I don't know the first thing about the internal devily going on inside a handset, I am only aware that the MIUI ROM is incapable of 4G which to me would point to some difference in the drivers or config, whatever.
The Telstra ROM can turn 4G off, the MIUI rom doesn't have 4G and the at&t rom defaults to LTE as much as you fight it in Australia.
Now that everyone is done poking holes in my knowledge, does anyone have anything constructive to add or should I just give up
i have mine set to GSM auto.
what does that mean? i want to save battery
where do you have that set, under *#*#4636#*#* ?

For some reason my sprint HTC ONE m7 can make call and recieve gsm data but no 3g or 4g. I have to set phone prefrences to gsm only, anything else and it wont even recieve gsm data.

Could it be that you have a CDMA phone running on a GSM network? You phone does not have the correct bands to get the higher data speeds on a GSM network!

Agreed. All other threads have been deleted.
Now you really should do your research before getting a device. You have a CDMA device and the best data you will get on a GSM network is Edge as the sim slot is only for data roaming.

Hello, I have gsm unlocked my sprint htc one and I'm now using Metro PCS network. Calls and Text work just fine but, when it comes to mobile data it runs super slow and I have no clue why. Any help appreciated.

Check your APN settings in Settings > Mobile Data > Access Point Name to see if they match these: http://unlockandrepair.com/metropcs-internet-mms-settings-for-android/
The other thing is that the Sprint HTC is primarily a CDMA phone with GSM cabability and the GSM bands may not get you fast data. For instance Sprint LTE band is 1900 whereas T-Mobile's LTE bands are 700, 1700/2100.

Yeah I'll give those APN settings a shot, I'm using T-Mobile's apn settings. Yeah I had read about the radio frequencies , when I first unlocked my phone to gsm no network providers other than Sprint would show up ... So I flashed a T-Mobile radio through twrp.

The bands are hard wired into the phones, the Radio you flashed just enhances the bands capabilities but can not add bands.
Oh I did not know that. Imma try out the settings.

i am having the same issues but with a different provider. i installed a custom rom now it shows 3G and H but it moves no faster than GPRS/EDGE. anyone?
I tried searching it, but I kept finding it for other phones and then answers that did not fit what I have. The most common answer is, if it has a sim card, it is GSM. Sprint is CDMA though, so is it CDMA and GSM? When I took the SIM card out, it said that I would not be able to use 4G LTE without the SIM, but I still had full bars, so does it use GSM for 4G, but CDMA for 2G (calls and sms). I was told that the Google PE RUU did not work on my phone because it only works on GSM, but then when I ran MSL finder, it told me it had no MSL (ie not a CDMA phone) and I have en IMEI, not an ESN.
This should be in q&a
If you're on Sprint or Verizon, you're using a CDMA carrier. Since CDMA is too old to support LTE, they used the SIM card to access access GSM technology (LTE) To keep up to date with the new carriers that are running insane download/uploading speeds using LTE.

Yup, if you choose GSM/UMTS, you won't be able to receive data at all since Sprint isn't a GSM carrier.

On that note, it has several options, including CDMA only, GSM only, and then gsm/cdma/wcdma/lte (ie all of them). Is it prudent to just leave it on all, or since I am going to use it on Verizon and/or sprint/ting, just leave it cdma/wcdma/lte? If I choose the catch all one that includes gsm, will it affect the phone negatively, as in extra battery usage, overheating, no signal, etc?

If you switch to CDMA Only, you're gonna get a much longer battery life than if you were using CDMA/LTE since your LTE service will be disabled. This means that you will only get 3G but your battery life will last longer since LTE requires more power than 3G
Hi guys,
I bought a SM920P Note 5 (Sprint) in , I could use 3G at VietNam without any problems but when I arrive at Japan, I can't use 3G anymore, only ordinary phone calls and SMS. The phone keeps alerting this error : lte:esm - 29 emm - x unable to stablish a wireless data connection.
I have entered the APN setting of the carrier. I tried to put the SIM into another phone and it works without problems.
In the settings>more>about device>status : the networks says HSPDA. So I changed the Bearer in the APN setting to HSPDA but still no luck !
My OS now is Nougat, and I don't think the phone is rooted because I'm receiving auto updates.
Does anyone know how to troubleshoot this problem?
Forgive me if there were missing information, just ask me and I will provide, sorry I'm not very "technical" !

I only have 4 mode in my network mode :
- CDMA
- LTE/CDMA
- GSM/UTMS
- Automatic
If I chose CDMA or LTE/CDMA there won't be any signal at all, the working options are GSM/UTMS and Automatic which I assume is the GSM/UTMS itselft.
Any ideas ??

Did you get Sprint to unlock your phone for a different carrier before you left? Those APN settings have to be set exactly right and you must save it. Once you change your network mode it may take a bit to get signal.

I do not know if rooting it would do you any good. I am not sure if changing the firmware would allow you to change carriers. I am not even positive that's the problem. Did it ask for some kind of code after you inserted the new SIM?
Is it a data only SIM? I think it needs to be a data only SIM being a CDMA phone.

No it did not ask for any code when I inserting the SIM, the SIM is capable of Call and SMS.

No problem. I could be wrong but I am pretty sure your Sprint phone is CDMA and I am pretty sure that the only thing your phone uses your SIM card for is LTE data. So if I am correct you need a SIM that is data only. The other phone it works in, is it CDMA or GSM?

Actually I don't know anything about the CDMA or GSM things. Here is the result I got from googling the spec of the other phone :
Technology
GSM / HSPA / LTE
So, assuming you're right, can I just "disable" the calling and SMS function of the SIM, make it to become a data only SIM? I already got into a 6 month contract here, so I can't change the contract type in about 5 months !!!

You are welcome. I do not think you can do that to a SIM. The other phone sounds like a GSM phone and if the SIM works in that phone it will not work in a CDMA phone. I would go to your new carrier and ask if there is anything they can help you with. That's assuming that you are not carrier locked to Sprint. Then you have the fact that the CDMA SIM will not work in your other phone.

Yes I am sure. I have seen CDMA carrier phones that were refurbished by third parties that "claim" they are unlocked for GSM carriers. I am not sure how much I trust that. You may hit up Sprint support and see if there is something they can do for you. If you bought it on contract from them they may not do anything for you.
Good luck.
