Hello,
I have searched throughly for my questions but didn't find anything unfortunately...
Will the tab 3 SM-T217S be able to make calls? I am talking regular calls not using apps that use data.
I live in a country where there is CDMA network provider and heard that there is no dialer on this tab which is important for me to programme the tab into my country's CDMA network provider.
I also came across a forum where it said the call functionality is there in the tab 3 but sprint has blocked it because the will only give you a plan with data not voice, so does that mean that if the SM-T217S gets programmed to another CDMA provider the call functionality can work normally??
I appreciate any help guys and thanks in advance!

Hey, i was about to purchase this to flash to IUSACELL Mexico, but instead went with the ATT version with SIM card because i have a better data plan with GSM provider than CDMA provider.
But i did some research prior going with the gsm tablet, and it appears you can flash it with DFS cdma soft, and of course if the new plan has DATA/VOICE it should work like a phone and sms and all that, providing you download a dialer and use an external hands free headset (i dont think it has a speaker like the GT3 8").
You wont find much information, all has to be done with trial and error.
hello every one.
My lte doesn't work. I already test with the rom paranoid and CM.
I m from morocco our 4g is new and i think is the same as the europe 4g (lte).
Do you have any idea ?
Pls help
Thank you for your time
up
Help pls i need to flash modem ?
Which carrier are you using in Europe? Are you roaming from T-Mobile or have you purchased a different service/SIM card in Europe?
Also, what country are you in specifically?
There was a guide somewhere on XDA regarding Qualcomm processors and band unlocking using QXDM (LTE) and QPST (GSM/WCDMA) though I forget the exact name. I believe there was also concern that it could damage antennas. Also I have no idea if it actually works and mucking around in the NV RAM space is very risky. I would not advise it.
Is at least the GSM service working? If so, is it really that bad that you need LTE? Personally I would leave it at "oh the gsm works, I'm good". :good:
Depends on the carrier you are using, is your phone unlocked? I would assume that it is since your can receive gsm signal.... Anyways, what you would want to do is check your network's APN and check our phones APN settings and add the 4g/LTE APN settings to your phone manually... Then restart your phone and try again, make sure you select the apn after adding it so you know it's active. Try that. If that doesnt work, then go into your APN settings again and just do (reset apn setings) or something along the lines of that which resets/restores your apn settings back to normal/default.... either one could work, try the first one first ofc!

Hi,
I opened another thread regarding safest method to change from unlocked stock os to the T-Mobile release for Wi-Fi calling, possibly in wrong area as somewhat related to T-Mobile, however my main worry is ensuring I will have full 4g/LTE support, I am awaiting a sim card of a T-Mobile mvno, but I've seen several places I'd likely not be able to even use 3g without enabling the bands required, I've come across various guides .
Several said to use ##3424# or something alike(I'm out right now so can't confirm) to get into diagnostics, this does not work, I can however use the *#*#3424#*#*(again might be incorrect code) however this is self check options and to calibrate vibration etc, unable to connect with qpst with this.
Any help would be helpful, I purchased the phone second hand unlocked to use when I visit the US, I know it's unlocked and works in UK, just require it for use in US as I use an m9 as my main phone.
Would be nice to get the Wi-Fi calling function but not important.
Any help on how to go about this would be great.
Regards,
V4mpire

Well I Have A T-Mobile RUU Thread I Made That You Could Use, It's Not Set For The US Or UK, Just For The T-Mobile Carrier
You Would Need A Windows Computer To Do This Tho. Reply Back If You Want The Link
Hello.
AT&T has disabled all the international GSM\LTE bands on Z999, making it unusable outside of USA (at least in countries with GSM 900\1800, UMTS 2100 & LTE B3 & B20, like the one I live in). In order to change that, we need to turn on the Qualcomm USB Diag port, and for this, the phone has to be rooted.
I've been trying to root my AT&T Z999 for some time now, without any success, unfortunately. However, searching forums after forums, sites after sites, I've discovered the surprisingly easy method of turning on the Diag port without root.
It appears, that Axon M shares a lot with Axon 7, at least the secret key combination to enter Factory Test Mode:
Turn off the phone
Press and hold Power + Vol DOWN buttons until you see the screen "FTM" (see attached screenshot)
You have to press both buttons for the long time, do not release them when the phone starts - just wait until you see the screen. And that's it - you are now in Factory Test Mode and PC sees your phone as "ZTE Handset Diagnostic Interface (COMxx)"
Now, in order to change the bands, you have to follow these guides one after one:
Backup IMEI and NVRAM (ignore all the steps to turn Diag port on, you've done that already)
Unlock LTE bands
Mod edit: Link removed! (this guide in in Russian, but all screenshots are in English & every step is pretty clear)
You would need this tool also.
Please remember, these things are complex, and require considerable experience with Android & Windows. DO NOT START unless you feel confident that you know, what you're doing. I'm serious. Do not try this, if you're not experienced.
WBR,
Draco.
Why mods deleted the link? Google translate exists.
Edit:
I've managed to get the data from the phone using QXDM.
lte_bc_config contained the value of "2251800618993690" now I'm parsing the info how to edit this. Seems like the tutorials don't really match this device. Now I wonder if the chipset can handle invalid data and just input all 1's. Unsupported frequencies just won't work.
Edit2: Writing all 1's didn't work.
Edit3: I wrote this value: "2251802901219551" Calculated with CDMATool. But it seems like the AT&T firmware only finds edge network. I've double checked the bands to be correct ones. So now I will switch to the chinese firmware.
Edit4: Final edit. Turns out you cannot flash chinese firmware on AT&T device. Sigh so my unit is stuck to EDGE/wifi only.

can you repost the 3rd link?
I can't "repost" the 3rd link, but I can suggest you to open the well-known (and the best) Russian web-site with the name starting with "4" (and having something like "...pda" also), and then add this to the address: /forum/index.php?showtopic=546814&st=4640#entry35702698
Well that russian site has pretty good instructions on how to do it. I tried with one program and it didn't work on AT&T ZTE. I'll try with that qualcomm app again this weekend but if I remember right the last time it had trouble writing because it had no correct service mode code \o/

that website's address ends with ".RU", doesnt it?
i accessed that website as your given link, but i cannot see any related threads about ZTE on that, seems all they disscussed about is Lenovo K910SS. was something wrong with my searching?

Every Quallcomm device has almost the same NVram configuration rules, the difference is usually on how to enable diagnostic port, but for Z999 I have figured that out already. So, for the configuration process, every Quallcomm guide should work.
I've successfully enabled Z999 to work with 2G & Edge in my country using these guides. 3G & LTE don't work yet, but I'm sure they will eventually. I don't believe Z999 lacks the hardware ability to use LTE B3 & B20 (and other bands), it has to be something wrong with NVram parameters.
For me 2G and Edge worked out of the box in Finland. Tried to enable more but only thing that changed was power usage. Not worth it

It means success unlock 2G/EDGE, not yet with 3G and LTE? When buy the device, it can use other carrer to call and 2G.
When you finger out the way to unlock LTE, please share me.
by the way, do you have the way to enter fastboot mode? I tried the "volunm + &power button" but it just do a normal restart into android.
Fair warning to everyone trying this, make sure you actually do a backup of your IMEI. I didn't and after screwing something up my SIM is no longer detected, and my IMEI is no longer available.
Hello folks!
I have an AT&T phone. I cannot connect to ANY (even EDGE) network!
I modified the configuration several times:
---
I have EDGE with this config:
00441: 0 and 0xFFFF
00946: 0 and 0x06A8
01877: 1677472
02954: 0
06828: 524356
06829: 524356
I got no LTE
---
test2:
06828: 524485
06829: 524485
I got no LTE
----
00441: 0xffff (but 0x380 is recommended)
00946: 0xff8
02954: 0 and 805765120
01877: 3460734838925427584
06828: 1904863
06829: 1904863
I got no LTE, just continous dropping network, useless config.
----
00441: 896
00946: 0 and 0x140
02954: 0 and 131072
01877: 562949974393728
Only edge network, error while searching for networks.
----
06828: 524485
06829: 524485
I have EDGE with this config, but no LTE.

Anyone has a good and working LTE mode?!
edit: "The bands on the AT&T z999 are: 2, 4, 5, 12, 29, 30, and 66. "
So, there won't be any Band 1,3,20 for us?!
Thanks!
No one has gotten LTE work on AT&T model. I wouldn't try this.

Have you been able to make 3G & LTE work? I just got my ZTE AXON M from ebay and since I can't use data or make calls/unlock the phone I was thinking of trying this.

Can I describe in detail how to enable 2G?
Thanks !
Hello guys. I've tried all configs mentioned by @ugynok and some of my own - the result is still the same, no 2G network and all options in mobile connections are disabled not clickable. Can you please advice which config worked for you to enable 2G network?
Any luck?
Hi all. Was anyone able to get a useful set of bands working in the UK for this phone?
Many thanks.

It's the mistake. I don't know how to delete it, sorry.
Hello everyone, first of all I would like to apologize because I am French and I don't speak English very well, but I think you are my last hope for the trouble I am currently experiencing.
I own a Samsung Galaxy Note 10+ (SM-N975F) with a Rom Surcouche Operator Bouygues Telecom :
- N975FXXU4CTE9/N975FBOG4CTE9/N975FXXU4CTE9
I wanted to remove my Bouygues Telecom Rom Operator to install a Samsung Rom Stock without any overlayer operator. The operation is well finished so I am now on the Samsung Rom Stock:
- N975FXXS6DTI5/N975FOXM6DDTH7/N975FXXS6DTI5
Except that since this change of Rom I have almost no more 4G+ where I live knowing that before I was always in 4G+ So I would like to know why just by having changed the Rom I lost my 4G+. ( Worries which lasts since September 21st, 2020 ) I wanted to go back but I passed from a bootloader 4 to a bootloader 6
Knowing that I'm with the Free operator, I tested my Free SIM card in my wife's Samsung, I'm getting 4G+ so the problem is not my SIM card, I also sent my phone to Samsung, the phone has no hardware anomaly so it's from the change of Rom, I tried to reinstall the same problem, I also made the wipe I tried everything ...
I also have at home a 4G+ router with a 4G+ plan with the operator Free and I am in 4G+ at full speed ...
I hope to get some help from you because on the French forums I don't have a single answer ... Thanks in advance for your help and sorry again for my english
Test the internet speed on both phones using your sim's data plan with speedtest. If the speed is the same in both then the problem of the 4G indicator is only aesthetic.
Hello bigcalvin, unfortunately I have tested but the speed is not the same at all in 4G+ I go up to 235Mb/s while in H+ I go up to 3Mb/s so there is no problem with the 4G indicator

Have you tried in different areas? What it seems like, is that the stock Samsung ROM is not compatible with your carrier. With system on a chip (SoC), carriers can turn off bands that they don't need, or as a means of locking you into their network.

Honestly I'm not going to lie to you I've tried everything I've tried a Bouygues télécom rom (bog) a SFR rom (sfr) a France télécom rom (ftm) and a Samsung stock France rom (xef) with my old Bouygues télécom rom (bog) bootloader 4 I always get the 4G+ since I changed my rom and I switched to bootloader 6 I never get the 4G/4G+ again and I sometimes get the 4G+ logos but there are 10 seconds left and then switch to the H+. ..
Hello, sorry for the double post but I don't know where to find help you wouldn't have a solution to my problem? Thanks in advance
I don't understand anything anymore on this phone knowing that my wife and at free and I can receive the 4g very well. I have a 4g router, I can receive the 4g free and my phone since the update doesn't receive anything anymore, I have to go out of my house and walk a good 100 meters to hope to receive the 4g whereas I didn't have this problem before I made the really strange update...
No one would have a solution to give me or manipulation to do I take all the information.
Try a "reset network settings" if you haven't already.
Clear the system cache on the boot menu; it never hurts to do so.
Hi, thank you for your answer unfortunately I have already reset the network settings I have also done the factory settings system cache also reinstallation of a new rom I had to do it about twenty times but still nothing :/

Yeah pretty basic stuff... that's all I got
Most likely a settings issue but you probably know more than myself at this point to troubleshoot this problem.
Try doing Google searches and view the results for other Samsung phone models and years.
Most times I can find a solution like this or trip over it as an indirect result while searching.
Some of the Samsung software issues have been around for years...
I've already searched everything on google I'm French I've searched on English forums and everything but I can't find anything at all.
I am in France with the mobile operator "Free" which uses the frequencies 700mhz/1800mhz/2600mhz I would like to know if there is a possibility on this phone to choose the frequency that I want one by one I have the impression that it is my 700mhz frequency that has a problem on my phone :/
By using the free App 'Shortcut Master (Lite) from Google Play, you can get access to the Network Settings. In there you can make Band Selection, allowing you to test network connections and performance per band (=frequency) or combinations of bands.
See following thread: https://forum.xda-developers.com/ga...guide-hidden-network-settings-exynos-t3995501
Hope this helps!
Hello OnnoJ, unfortunately I have already tested with this application so it doesn't work. However I compared everything with my wife's phone a Samsung so I have exactly the same settings as on her phone ...
I have to go out of my house and walk a good 200 meters to hope to get 4G, however I specify that before I made this famous update I was always in 4G at home inside and outside of the house and this is not a concern of the mobile operator because otherwise my wife would have exactly the same problem as I have now and I would also have exactly the same problem on my 4G router ...
I think I've done everything and above all I've tested everything and unfortunately I had Samsung on the phone and they put the blame on the operator whereas as explained above my 4G router and my wife's phone have exactly the same mobile operator so they would have the same problem as me ... ...
I would try to revert to the newest firmware that your carrier uses, just to see if the issue is about the bands, search for the latest firm for your carrier, provided that it is of an equal or higher bootloader version to the one you currently have installed, that is what I would do
@thominekevin76000.
Not saying it may help you, but the application works fine for me to access network settings. I use it all the time, as it helps me at home and at work to make the optimum band selection for that specific location to prevent hopping between different cell towers and to have a stable and fastest possible 4G+ connection. CellMapper app allows me to see connection possibilities with the various cell towers and their power.
Hello winol, I can't go back to my old Rom because I had a bootloader of 4 and now I switched to a bootloader of 6 so I can't go back :/)
