[Q] LTE on One X International

Anyone manage to get this working and do speed test? Im about to get an LTE enabled sim with MTN SA and test if it works, opening up phone information, you do get an option for GSM/WCDMA/lte auto.

There is no LTE Modem for the Tegra 3 so no chance
cheers

we can't use LTE (4G) on our international phones regardless of the sim card... that's why carriers like t-mobile and orange are offering to part-exchange our one x (international) for the one xl which can use 4G

[QUESTION] LS 980 on GSM?

I am considering to buy this set.
G2 Ls980.
Will this set work with GSM frequencies?
Does 2g/EDGE/3G/4G work on it? (GSM)
Thanks in advance

Thanks a lot. It works supports GSM fine.
What about 3g? Does it support that as well? It says CDMA while other mobile specs mentions UMTS.
If you own this set. Can you confirm if the GPS works without internet?

Hi AhmedRana
I have ls950 and am using in India with GSM operator Vodafone. Both 2G and 3G data work fine.
I could not test 4G As India is using LTE band 40 which is not support by ls980.
I think the phone GPS needs data connection to work.
Hope it helps

i m using this phone in india with cloudy g2 2.2 works good on all networks 2g 3g .. gps works without data connection..
buy it .

I am using this phone on Cricket in U.S. which is ATT (GSM) and I'm getting HSPA+ speeds.
Sent from my LG-LS980 using XDA Free mobile app

The LS980 (Sprint G2) works fine on 2G, 3G/UMTS, and 3.5G aka HSPA and HSPA+ networks here in the U.S. for AT&T and T-Mobile - it will not work on any LTE networks in the U.S. except Sprint's network because it is limited to using their particular LTE bands (bands 25, 26, and 41) which do not have any crossover for AT&T (bands 2, 4, and 17) or T-Mobile (bands 2, 4, and 12).
With the last G2 I had (might be getting another one later today, another LS980) I was easily pulling down close to 39Mbps using T-Mobile's HSPA+ without issues which is just shy of the theoretical maximum of 42Mbps so it worked great for me, YMMV as always.

for 3G, isn't LS980 limited to UMTS band 2100 ?
what about the other bands 850/900/1900 ?

Back of phone's box. See by yourselves.

Not enough info. Need the phone's CID, and what 3G (UMTS) bands used by your carrier.

I Google and found this CID for my phone spcs_001. I got to know this from terminal emulator. Sorry but I don't know what band is used by my carrier.but I recently took 4g sim from my carrier which is working great on my brothers phone but not on my phone。I am using Airtel's 4g SIM and not able to use even 3g on it .

Call your carrier and ask them, they can answer this.
Nobody here can help you, if you don't give this simple information.

Thanks, I have called my carrier and they advised that 2100 for UMTS (3G) and 2300 LTE (4g) band is used by Airtel.

You have the Sprint version of the phone (based on CID) which should be compatible with 2100 MHz (UMTS). This phone does not support 2300 LTE, but you may already be aware of that.
Are you sure your carrier's APN info is entered correctly?
You sure 3G worked for a week? Any changes that happened that could have have changed that?

Thanks for sharing this detail, I was not aware about the 4g which you mentioned. Yes my APN is correct and i have crossed checked with my carrier as well. And yes i have used 3g for a week and after that I took another SIM from my carrier(Airtel) 4g sim and just after that my 3g stopped working.
And I have checked my new sim in another phone so it's working fantastic but not in my phone. and I have checked my brother SIM in my phone so even that sim's 3g is not working on my phone. I could not understand all of sudden what went wrong which it stopped working.

Check the APN again, and that is the currently selected, active APN. All I can think, is that inserting another SIM changed the APN.

I checked again, but still same issue. What should I do any suggestion. Or could this be a software or hardware issue how to know this. Any idea

Data issues

So I have a Verizon model M9 using it with a GSM sim. Its a data sim which can roam on both T-Mobile and AT&T.
Here is my issue, T-Mobile is only EDGE in my area, and the phone works perfectly fine on that, but for some strange reason on AT&T HSPA+/3G It will work for a few min and all the sudden stop working even though "H" will still be at the top of the phone like data is there when its went away.
Its not the carrier, or the sim as this exact sim works perfectly fine with my Verizon G4, iPhone 6S, iPhone 5, and so on with no issues.
Any suggestions for those who use this model on another carrier? Or any suggestions what May be causing this?
I've changed my SKU, S-off, root, etc even running stock roms (non verizon roms) , same issue so its not Verizon software causing it. Also tried setting it to WCDMA and other settings and the issue still occurs.
Any ideas would be great! I really like this phone and hate to have to sell it and go find something else or may end up going back to my G2 for my 2nd line. Could Fast Dormancy cause this?
Thanks!

You're going to be handicapped by the physical limitations of the Verizon M9. Check out what bands T-Mobile & AT&T use and see which ones match up with your moel. The bands that the Verizon HTC M9 supports are:
LTE Band 13/4 (700/1700MHz),
CDMA/1xEVDO Rev. A (800/1900 MHz)
EDGE/GSM (850/900/1800/1900)
HSPA/UMTS(850/900/1900/2100)

Thanks but it's not a matter of being supported. It supports AT&T 100% 2G and 3G wise. I get HSPA+ just fine without issue its a matter of the phone some how loosing data connection randomly until putting it into airplane mode or rechoosing the network under network selection. But it's fully supported AT&T 3G wise.

There is a thread in the forums by stifilz to enable more bands but if that's not the issue than something that worked for me was here

Thanks I might try that. Yeah it's not the matter of the bands is the issue.
What's strange is I'm not having signal issues as signal is perfect it's just the weird loosing data issue while signal is perfectly fine. But worth a shot.

My phone will only work with GSM.

My internet works only with GSM.
When I change to LTE / 4G it will not work.
I flash back to stock.
It has worked LTE 4G earlier.
I have the correct APN set.
Could it be a setting in my phone or hardware?
