Does anyone understand the cellular radio architecture inside the Galaxy Tab S2 LTE?? - General Questions and Answers

Hi all,
Could someone please help me understand how the Galaxy Tab S2 is unable to conduct itself as a cell phone??
Please no comments about how the carrier doesnt "allow" it, or directions to VOIP solutions like Google Voice or Skype.
Why the fsck cant I EXCHANGE MONEY FOR A LARGE TABLET DEVICE THAT HAS A CELLULAR PHONE ON IT????
Why is this so hard??
In the past, similar issues were hacked by this community to allow unlocking from carriers...
I am just surprised that no answer exists and not even a cogent explanation of why it cannot be done.
I.E. I remember on some of my old phones the radio chip was frequency-locked in the cellular radio firmware. Then I remember people produced hacks to unlock/reflash the radio firmware... etc...
Can someone give me a good solid technical answer, please?
Thank-you, in advance!
Sitting on a $650 device that is half useless to me. I thought for SURE this was just a small-mod fix.

Typically, tablets do not have cellular function in their radio, they typically only use WiFi and mobile data, not cellular signal. It's a hardware thing, not a software thing, it can't do something that it does not have the hardware for, whether you like it or not.
You can install apps that allow calling and texting over WiFi but that's it.

[Q] Wifi only model (GT-P6210) GSM/cellular capability?

Does the galaxy tab plus wifi model (GT-P6210) have GSM capability?
I've been searching/reading for the last few hours, but I haven't found a definitive product manual/spec sheet that answers my question... a lot of the spec sheets online have conflicting info.
basically, i'd like to get a tab+, and run it as a wifi tablet around the house, but also be able to run it through the tmobile voice plan as a cell phone (NOT DATA PLAN) after rooting/installed sim card. samsungs website only lists GSM band support for the GT-P6200 model, so i wasn't sure if the antenna was in the wifi only model (GT-P6210) and disabled, or absent completely.
sorry for being a noob about the devices' capability. i have genuinely searched around this forum and dealers websites but would appreciate confirmation from somebody that has actually done this (or something similar)
thx
No. It does not. That's why it is called wifi only...

thanks, thats what i initially assumed, but some tmobile tech support was trying to convince me otherwise and i didnt want to drop money for one without confirmation.
It has no cellular hardware. You can set up a pbx if you want to make calls over wifi, but that's about it. I just tether it to my phone over wifi

How to add radiobands to the Infuse

Of course, i don't have a clue how to :laugh:
I ask the community here if its possible, for the carrier T-Mobile, to add basebands to the Samsung Infuse 4G
Its very possible as the tech is closely related... but you have to program the modem... correct?
If this isn't possible..even to gain some sort of band... root... any sort of way to gain more then 2G speeds with t-mobile..yes im using att phone and yes its unlocked... im willing to do whatever to get better speeds xD...and not switchover to att..
It is my understanding that if you flash an improper radio you will hardbrick. Have read this in the N1 forums and would guess it would apply here. The problem is more so the different bands that T-mo uses vs AT&T. Others more knowledgeable than I hopefully will post. Regards.

Possible...yes-chances of it happening...most likely not
People are asking the same thing over in the vivid section (one guy offering a $100 to the first dev to accomplish it) after a little reading...I've found that "bands" are not really bands...its just deep coding that basicly tells what frequencies to use per channel and all that...it requires software hacking to the extreme...only very extremely expierenced/knowledgeable devs and Samsung themself would be able to do it...
Here's the vivid thread http://forum.xda-developers.com/showthread.php?t=1807740
And here's a link to another thread http://forum.xda-developers.com/showthread.php?t=1548553 (that was in the vivid thread op) with a guy explaining how it is possible and proving everybody wrong that were saying its impossible
Now...I can't be positive its possible but after reading that guys arguments I'm convinced it is possible...but only the experts would be able to do it...

[Q] Galaxy S3 R530U 3G connectivity problem

Ok so im a noob to US cellular, but had a At&t S3 and many other phones and have done alot of rooting, custom roms, etc. installing, and never had this happen, I guess i'm trying to say the development for this phone isn't as high as the other bigger carriers. But I had multiple issues with several of the us cell roms for the s3 and last night i tried to put cm10 stable from the official website and afterwards now my phone only gets 4G lte, and the data works but when i go to send a message or call someone it doesn't work! When i go to mobile networks in more settings and switch to cdma only, i get the circle with the line through it or my phone roams non stop! As i know the 3G antenna or what not is the voice and texting part and the other antenna is the 4G lte one, so i think when i flashed either the cm10 or the k747 kernel one or the other screwed up that part of my phone? Has this happened to anyone else and if so could u find a solution? And yes i called us cell and they went through everything and said it must be hardware related, so idk if i have any other option but to send it in or do a warranty exchange. Please let me know if any of you have had this happen, I miss my phone and have never had this happen Thanks! Let me know if you need more info also!

[Completed] Mobile hotspot boosting apparatus/Reception issues

Hello!
Is it possible to buy the following items and use them as a mobile hotspot boosting device?
- http://www.pcmag.com/article2/0,2817,2402900,00.asp
- http://www.verizonwireless.com/acce...ase-Affinity-Others__Also_Viewed-mls_acc40151
- http://www.verizonwireless.com/accessories/adapter-cable-for-usb-lte-modem/
- http://www.amazon.com/gp/product/B005NGLTZQ/?tag=lifehackeramzn-20&ascsubtag=
I am grandfathered on verizon's unlimited data still and I am constantly traveling around California. Specifically my room and other remote areas I visit for work I can pull down decent 3g and sometimes 1 bar of LTE.
((( I purchased this item almost a year ago and used the SIM card in my phone to gain 4G signal then I connected to the network via WiFi. Everything worked fine but it was bothersome to continuously switch out my SIM card between devices so frequently whenever I couldn't take the hotspot with me. Seeing as the present situation I am involved with needs the older setup I had before; convenience is welcome.
- http://www.bestbuy.com/site/verizon...spot/8939305.p?id=1218956066940&skuId=8939305 )))
So here I am trying to build a badass device and mount/carry in my bag while on the go.
Will the first parts I have listed above work? I am worried the boost in signal might not warrant the setup I have planned. Then again if it works as intended it could be extremely useful. Any incite is appreciated!
Furthermore, I have a software related question that could be an alternative solution to my problem.
-The ROM I am currently running is Gummy-M3.0-07-21-14-NIGHTLY-d2lte
-The Baseband version is I535VRUCML1.
Is there anyway having this firmware version is interfering with my reception?
The Gummy ROM is currently on Android 4.4.4. Is there a newer firmware I can flash to update the baseband to receive better signal?
Again thank you for reading and I hope to hear any advice or past experience that could potentially help me out!

[Completed] Noob in need of radio/modem flashing information

Hello,
I recently purchased a note 5 duos SM-N9208 from Taiwan. I was led to believe that the device was unlocked GSM, but had EV-DO capabilities. My understanding was that this would work on Verizon's network, because it had both radio chips inside. I was told by Verizon that "there is no approved way" for them to get me up and running on their network. The tech made a point of saying there is a difference between approved, and no way. This leads me to believe that something can be done. I'm wondering if someone would be kind enough to help me out. Phone is running original Rom, unrooted, and is basically useless to me right now, as I'm desperately clinging on to my unlimited data with Verizon. Is it possible to root the device, and flash the modem with Verizon note 5 baseband info? Any help anyone can offer would be very much appreciated.

Hi, and welcome to XDA!
When I looked up the specs on the Note 5 Duos, unfortunately it says nothing about CDMA. Having both "radio chips inside" can be taken two ways, in this case, this phone has the capability to handle two GSM carriers (and in this case, like most dual-sim phones, only the first SIM can do 3G/4G/LTE speeds).
Network Technology GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 1900 / 2100
4G bands LTE
Speed HSPA 42.2/5.76 Mbps, LTE
GPRS Yes
EDGE Yes

It seems the only option (if you want to use this phone), is to join a GSM carrier like AT&T, T-Mobile, or one of their MVNO's (like MetroPCS).
Hope this helps.

Thank you, Joel! I'm excited to learn as much as possible from tgis forum. I actually changed over to T-Mobile, and have been good for the most part. The problem i'm having now is related to finding a way to flash the radio to all of their Rf's. I rooted, and attempted to flash the modem and bootloader from N920T, but it failed. I am still having a hard timr understanding why the identical hardware will not accept firmware from different model numbers. Again, very inexperienced, so it may be something very obvious i dont know about. If could offer any assistance, or provide and thread links that may be useful, i wpuld very grateful. Ive been searching nonstop, reading, and still cant seem to find a way.

Well, the hardware (particularly the modem) is not compatible, hance the failed install. You are lucky it cancelled out as you could have had worse problems on your hands.
The way i see it, you will have to wait for other regions for the Note 5 Duos to open up before you get flashing options. I would even question the need for that, if you get a decent range of bands with T-Mo (I am assuming you can get 4G).
If you want to explore further anyway, please check out this thread:

It did, thank you! I get decent service (including LTE) almost everywhere. Problem is, once I get to my.house, I go completely out of service. No call.I no text. It wouldn't be a big deal, but the Taiwanese phone doesn't have a way to turn WiFi calling.

Aha. That and no sign of the 700mHz band (which may not be part of your phone anyway, not just hidden by the current firmware).
Since the firmware would need deep support of Wifi Calling (or VoLTE), as in more than just an App, I am afraid you will have to wait until the Duos releases into an area with that support in their firmware (and hope that, that area's firmware doesn't disable a frequency you use).
Makes scraping all the lead paint[*] off the house the more manageable task, doesn't it?
[*] I really don't know if your house does indeed have lead paint. I am assuming it's coated in something metal, or concrete, which avoids typically high frequency radio waves from entering. I never had that problem with my house (which may be strange, since it was built in the 40's), but maybe creating ways to boost the existing signal may be in order instead.
