Problem with 1900 Mhz Band (GSM and UMTS) - LeEco Le Max 2 Guides, News, & Discussion

I recently own a X829 variant with 16S stock rom. Use dual sim feature and this is all I can get in data usage (voice works ok do):
SIM 1: 4G 2600 mhz OK, 3G and 2G 1900 mhz NOT WORKING
SIM 2: 4G 2600 mhz OK, 3G and 2G 850 mhz OK
The phone detects 1900 mhz band (either 2G or 3G) and I can use it for calls, but it cannot use it for data. I want to use the data plan of SIM 1 because I have much better data plan.
If 1900 mhz were not supported (Information says it is), even voice call wouldnt work, right?
Maybe I will need a unlock band feature provided by this user?: https://forum.xda-developers.com/le-max-2/how-to/guide-unlock-bands-leeco-le-max-2-fix-t3439154
Best regards to all

Your using T-Mobile in the states? ( location and available bands might be a factor)
Sounds like maybe just a settings issue. If you remove one sim, can you connect to these bands?
I'm using at&t in the states and specifically use one sim for data, and second for calls/texts, but can only use ONE at 4g at a time.... Can't have both at LTE connection.

I'm afraid not, I'm from Chile so I'm using local providers:
SIM1: Entel
SIM2: Movistar
I already test switching SIMs trays, I know I cannot use tray 2 for 4G/data. but it's funny I can only use 4G in both SIMCards in tray 1, but not 3G/2G in Entel carrier.
So If I use SIM1 in tray 1 only I get 4G, wich is good, but as I move far from city and 4G is not available, it will switch to 3G/2G (it appears in phone tray) and data will not be available anymore.

Install official Chinese s23. From the official leeco page. That will upgrade radio firmware and fingerprint firmware, from there, then you can flash any other custom ROM or stay with s23. Which is stable and good. Also full date wipe is recommended.

I'm not familiar with those carriers, but google says all those bands should be supported. My only other suggestion would be to upgrade the firmware like already suggested.
16s on x829 was made for the states, not sure if that's what's holding you back,
Remember to backup, save your data and modem files.

Ok, so I tried Indian 16s, and a (slighthy) moddified chinese 23s without success, same issue: can call in 2G/3G 1900 Mhz Band but data doesnt work in that band.

3g problems

Hi. Newbie in this forum. Bought an htc tytn from u.s. but am from Phil using smart carrier with gsm band at 1800. after going thru sev topics, properly identified device as Herm200 rom:1.18.255.3 07/22/06 extrom:1.18.255.106 radio1.03.03.10 protocol32.34.7010.01H.
All phone features working perfectly except for 3G. Smart carrier people cannot help. What could be wrong. Vendor says 3g works on 2100 band. Confusing statement. What can be done? Connects to umts but when video call is pressed will not connect.
Which carrier are you on again? Smart Carrier? .. From what I know no carriers in the US support video calling .. Also, Cingular is the only GSM carrier in the US with 3G which runs on the 1900Mhz band ..
also .. what does your phone display while connected "G" or "U" ... what are your phone band settings .. can you also goto dslreports.com/mspeed and see what speeds are you getting ..
According to GSM world SMART (a Philippine operator) uses UMTS 2100, which your TyTN does definitely support.
Have you checked if your SIM card is 3G-enabled? Most 3G networks require special USIMs for 3G usage.
I just learned, that Cingular uses UMTS 850 and 1900 to be exact. According to the American HTC website the Cingular 8525 supports "Tri-band UMTS/HSDPA high speed wireless data network support (2100MHz and 850/1900 MHz), Quad-band GSMĀ®/GPRS/EDGE worldphone".
Does anyone know if there is a special hardware version, that supports UMTS850 & 1900 or will my European TyTN work on those networks, too?
TyTN is tri-band UMTS .. 850/1900/2100 .. so it should work on these networks without any issues ...
And my bad .. didnt realize that you are trying to use the TyTN in Phillipines ..
You should also check, if the called party has a 3G signal, while you call him. Further make sure video calls are activated by your network operator.
3g problems in the philippines
Everything you guys mentioned in order(am in a 3g area calling a 3g enabled party with a 3g sim card). Even the tech staff behind Smart Communications cannot make it work. Displays U and u. But video call cannot push thru even if pic on front camera shows. There is 1 thin line( or command?) stopping it from connecting. My last option is to borrow my friend's unit and see if her unit's 3g works here then it's my device that's a problem. Thnks for the input. Keep it coming.

Hi. I don't know how they did it but Smart Communications did it! Apparently and ironically their 3g sim card is not compatible with the htc tytn but their regular sim is. Thanks all.
are u using 3G now in Phil ?
Is there a Globe perpaid 3G simcard ?
3g problems no more
Hi everyone. After my first thread i have finally got everything on my tytn working: 3g, mms, internet, phone. The problem was on the settings. Smart and Globe, the primary carriers in the Philippines can both work on the phone if the settings are right.
sectorlord,
yes there is 3g and hsdpa along with gsm and gprs and wap in the philippines. and yes you can buy globe prepaid 3g sim card.
glad to hear you've got your problems solved jjc!

[Q] frequency on my GSM carier

hi guys
im from Israel..
i just got a new HTC aria device
i unlocked it with a code for any GSM carier for supported Israeli's network
now the phone is no longer under AT&T, it for Cellcom (an Israeli company)
the device support this:
HSPA/UMTS/(1900/850MHZ) GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ)
Cellcom SIM CARD support this:
HSPA/UMTS/(2100MHZ) GSM/GPRS/EDGE (Quad band 850/900/1800/1900MHZ)
when i entered a regular sim which is for GSM only the device worked just fine..
but when i entered the USIM (the HSPDA's supported sim card - that suppose to support the GSM frequency as well) the device couldnt recognize any carier..
what should i need to do?
is there a way for changing the sim card frequency settings from the Android's settings?
do i have any possibilty for using HSPDA supported sim card without supported frequency in Israel?? because the device soesnt know the 2100MHZ HSPDA freq.
cause i thougt that device will handle this issue (works for calls) and will block me only when ill want to web through the Cellcom mobile in HSPDA
but still will let me to web through GSM witch is more slowly..
HeLPPPPP
i think you're out of luck unless you get the proper sim card for the proper frequencies.
Since Cellcom uses UMTS 2100, you would have been better off to buy an Asian or European phone. AT&T doesn't use the 2100 band and decided not to include it in this phone. You won't get 3G on that carrier.
According to Wikipedia, another provider - Pelephone - has some of its 3G service on the 850 band which would be supported by the Aria. But in any area that is served only by the 2100 band, your Aria will not get 3G.
No idea why one particular SIM isn't letting you onto their GSM network.

[Q] D802 Not connecting network

My new LG G2 D802 seems to only want to conect to GSM, if I have it set to any other setting like GSM/Wcda auto, or LTE etc it wont even connect to GSM let alone the other networks? To be clear i can use the phone set to GSM, but not when set to the other settings, just keeps searching for network
I am in New Zealand on Vodafone network which is
2G - 900/ 1800 MHz GSM, GPRS
3G - 900/ 2100 MHz UMTS, HSPA, HSPA+, DC-HSPA+
4G - 1800 MHz LTE
so I think the phone should connect shouldnt it? I am in 3G/WCDA coverage (not in 4g currently to try)
Any ideas?
the phone is stock rom, rooted, Xposed etc, Kitkat 4.4.2
Thanks
Edit, I just clicked network operators and searched and it came up with Vodafone Gsm which i have selected. So i take it my phone cant see a 3g network?
I think I have solved it. I went into the hidden menu and changed the modem settings to my carriers frequency instead of auto. So fingers crossed. II havedone a reboot and it is still working too.
So I had 3g for the day or so and then its gone again, I tried my wifes sim card which is on a different network and seemed to work, so i will get a new sim card for myself and hopefully be ok. my current sim card works ok in her phone, it just struggles to find 3g in mine for some reason.
Got a new sim card now but it still struggle to find 3g maybe because I'm not in a main town centre but I should still have service here as I am in there coverage area and my wife gets coverage on her phone
Tried updating to lollipop but problemremains. It is disconnecting maybe because of poor 3g reception but then struggles to connect to 2g again. Only solution to have working phone is ro have it set on gsm only all the time. Not good

Problem with 4G signal @ Dutch vodafone 800, 1800, 2600 MHz

Hello,
I have the following problem: I can't get a 4G signal with my provider.
Vodafone Netherlands uses 800, 1800, 2600 MHz for 4G connection.
I have bought my telephone at flosmall . com
It should work, or do I forget something?
Can somebody explain this?
I had the same.
I tried some 4g signals apps to check my connection. This one seemed to fix it: https://play.google.com/store/apps/details?id=com.mcstealthapps3.networksignalsearch
Let me know if it worked for you!
I have trieded with the app but nothing changed.
But still on 3G...
I need to ask this.
Is your SIM card even 4G capable? If its older than 3-4 years it might not be.
I don't know anything about vodafone, but try googling, for one of my providers I actually needed to activate 4G on their website after logging in to my account.
Also. Settings -> Dual SIM & mobile networks. Is network mode set to 4G priority and Celluar data to correct SIM card if you are using dual setup.
Yes the sim card is capable with 4G (was using it on Lumia 950XL).
Have contacted Vodafone about the problem.
But the will only support devices that Vodafone Netherlands will be sell.
Have tried to flash lineage rom, but nothing change about the signal.
(stock Rom was from groschopp)
I also have a Le Pro 3 (x720) on the same network in the Netherlands and I have no issues with 4g.
I am currently using the Grossoshop-Rom (Build-number WAXCNFN5902011181S).
You can download several signal apps in the play-store to see if Band 20 is available to you, this is the one used in my region for 4g Vodafone.
I assume you set the preferred network type to 4G?
It's working now
Have called Vodafone again for some extra information about the frequency band for 4G.
But nobody could help me, there was one person that say i can give you a other simcard type maybe it will help. (I say how will it help if 4G works on a other phone with the same sim card, but let's just test it)
Afterwards the call, visited the shop for a other sim card
Doing the sim in slot 1 nothing changed, same 3G signal.
Was thinking this the last try and do the sim card in slot 2 and after 10 minutes i have LTE signal.
Trying slot 1 again but only 3G. changed back to slot 2 and solved.
Have earlier check slot 2 with me "older" sim card and only 3G was showing up.
I have noticed stock ROMs have better signals than say CM

You need to enter the APN settings for your provider's data coverage in the Mobile data section of Settings.

Are you on a custom ROM? Maybe it did something to the modem. If so, you need to return to a stock ROM and try.
The phone has all the bands it needs to work on your carrier, and my carrier as well. My SIM already had the APN settings for my carrier on it, and I connected to LTE right away on my x722. I'm on a vendor ROM, which is pretty much just stock eUI. I can't fathom why it doesn't work for you if you're still on stock. Have you tried the SIM in other phones?
I also have this problem in Romania with my LeECO Le Pro3, but with Orange 800,1800 and 2600Mhz. The only solution for this problem was to manualy search and select the 4G operator network. Although in settings/network operator it was on 4G/3G/2G(Auto) by default, my phone was stuck in H+/H/3G until i manualy search and select 4G. If you are sure your SIM is 4G and you have the corect APN you can try this but you will have to search and select for several times manualy to work. I find this solution very uncomfortable because every time you restart your phone or put it in airplain mode, you will have to repeat manual searches and register in 4G.
my x720 doesn't have the correct bands active. i activated them with qpst but only actived and running in sim2 (sim 1 actived but no gain lte signal)
ah! i'm on 20s
