I have an ATT Samsung galaxy tab 2 10.1 SGH-i497. I am trying to see if I there is a ROM that I can install on my device to make the GSM calls functioning just as in the Samsung tab 2 10.1 GT-P5100.
Please help...
Same problem with me.
Its hurting that even loading data packages becomes tedious.
I have to remove the sim card and insert it into some phone to do that since here in Uganda, Africa, we use codes to do that eg *100#
then reinsert it back into the tablet to use the data.

Add me to this request to see if we can make this Samsung Tab2 gsm calling capable.
Thanks
Voice Call Workaround
Sorry I'm late to this party. I recently purchased this tablet on eBay in pristine condition, and it is amazing. I started right away experimenting with voice calling. I purchased a SIM from Straight Talk with the usual unlimited plan (just like I would for a cell phone) and popped it in. The tablet had no problems recognizing the SIM and the phone number on it. Based on the hardware, at least from what I can see, the tablet seems to have the physical ability to handle calls so I suspect the inability to do so is software-related. However, I'm not a ROM expert (nowhere near - just a noob who knows enough to be dangerous), so I didn't feel like taking that risk. So, I found another solution - VOIP.
Since the tablet supports both WIFI and 3G/4G/LTE, a VOIP number that can be carried on those data streams would work. I tested this by creating a Google Voice number, and downloading the new Hangouts dialer app and got everything set up. Sure enough, I am now able to make and receive voice calls using this method. The SIM would ensure that I have data when no WIFI is available. Per the specs, this tablet should support HSDPA 850 / 1700 / 1900 / 2100, so T-Mobile's $30/mo 5gig plan seems like a good cheaper option as I don't need the talk minutes anyway.
I know that a native voice solution would be preferable, but, in the meantime, this is a decent workaround that solved my problem, and hopefully could prove useful to someone.
SGH-1497
DO I hate this Tablet?
I got it mainly for the sim. slapped a ST sim in and away I go. See a phone app in ROM Manager See all the would leave me to believe I can make in and out calls on this thing. As of Jan 15 is this a forgotten relic and a crock of stewed crap to mess with to get working? If so Im heading for ebay or so,ewhere I want a 10.1 that I can use ST on and have 4G LTE. Can anyone reply to me where and what I need to make this happen. I just bought this for 100 bucks and I wont smash it into the wall but not real interested in it. With GO SMS it gives me a Straight Talk number and I can text with it but no dialer with a phone app running in the background? geez kick in the purse anyone?
Pls i need custom recovery for samsung tab 2 sgh i497
First off, if this is the wrong place for device support let me know, and redirect me, thanks
So, I have a Galaxy Axiom, which as you may know is a US Cellular device. I mainly want this to work because it has band 12, and that'd be a really nice feature to have, as my main phone, Nexus 5, doesn't have it.
I have two activated sim cards, one for my Nexus and one for the Galaxy Axiom which I am having trouble getting to work. After inserting the SIM, all I can do is receive text messages. I cannot send texts, place/receive calls, or use data.
Some screenshots of the device status: http://imgur.com/a/vuCxl
Proof of texting "working" http://imgur.com/fvfFaVg
I would also like to note that in the mobile network settings, there are no APN settings, I was thinking that maybe it would fix it, but not if there are no settings to do that.
Another note: This line has been on the account for multiple years now, SIM mainly used on my Galaxy S Blaze as a spare.
Thank you in advance, everyone here!
I'm pretty new to both rooting and this website, so I apologize in advance for any newbie mistakes I'm gonna make.
Background:
I have a VS-996 which frankensteined and unlocked by following this post . After doing that I flashed pie and then flashed lineage os from here . That rom wasn't very stable and kept crashing, so I tried others. I wound up going with Havoc OS. I believe it was in 3.4 when I first flashed it. I've kept up with the updates up to 3.7.
The Problems:
Havoc OS works fine for me, very stable, except for some reason phone calls and messages(both sms and MMS) are spotty at best. Sometimes texts won't send at all, or they'll act like they sent but the text won't be recieved. Sometimes my phone will say I can make emergency calls only. Group messages and sending pictures don't seem to work at all, at any time. These issues seem most prevalent immediately after booting my phone up. Data works perfectly except sometimes when the phone doesn't like to register that the SIM is inserted for a little bit after booting up.
What I've tried:
I've tried reinstalling the rom.
I've tried installing different Android 10 roms.
I've tried going through the process again starting at the the Frankenstein method and going from there.
I've tried messing with the apn
If I flash back to a stock pie ROM everything goes back to working perfectly, and I'm using my sim in my old V20 while I try to sort this out, so I know the SIM is not to blame.
I've been unable to find anybody else with this particular problem, though that could just be because the problems cover so many different aspects that I'm not sure exactly how to search for answers.
Any help is appreciated, thanks.

Are you Verizon customer? You say you have VS996.
There's an LOS ROM bug for Verizon SIM card users where upon rebooting the phone you have to make a phone call first to then receive texts. This phone call "registers" the SIM card or whatever. Many people call their voicemail number to satisfy this requirement.
This bug affects all LOS-based ROMs.
Yes I am a verizon customer. I had noticed that making a phone call seemed to help things along when messages wouldn't send. I guess I managed to let my phone die or turn it off enough to hide the fact that it fixed me. Giving it a test just now it seems to be working correctly. I don't know if I'll be happy or mad if the solution turns out to be this simple.

Was noted extensively on LOS-16 ROMs, but not discussed as much with LOS-17 (Android 10) ROMs. But earlier this month someone in the Havoc 3.7 (LOS-17 based) thread did bring it up...

However, the larger problem is in six months you will not be able to use LOS-based custom ROMs with V30 on Verizon.
* As of December 31, 2020 Verizon is dropping 3G CDMA to repurpose bandwidth for 5G.
After that date, to make any phone calls on Verizon you will need VoLTE. No LOS-based custom ROMs have VoLTE. You will need stock Verizon firmware. It can be rooted stock firmware; you can use Magisk modules to add features -- but needs to be Verizon firmware for VoLTE.
* T-mobile users are in the same predicament.
In January 2021, T-mobile will be dropping 3G HSPA for same reasons. T-mobile users will need VoLTE, which only comes with V30 stock firmware. However, T-mobile is less stingy. They also allow US998 firmware to have VoLTE and Wi-Fi calling with T-mobile SIM. Whereas Verizon requires Verizon stock firmware, and it needs to have been activated on a phone with Verizon IMEI at some point.
* AT&T will also eventually drop 3G HSPA -- but not until February 2022 (18 months from now).
So, for U.S. V30 owners who wish to run custom ROMs a little longer, you should check out AT&T Prepaid. It's a lot cheaper than "regular" AT&T, but is only for people who own their phones.
18 months is a long time. Anything can happen in 18 months!
AT&T only gives VoLTE to AT&T IMEI phones, as well as iPhones and some other phones I would never own. I've never used an AT&T branded phone on AT&T. I'm an AT&T customer with three native US998 for myself, my wife, my mother -- so I'll cross that bridge when I come to it in February 2022. Will probably give my mother an AT&T V35. Maybe my wife, too. Also, LG may get their act together and produce a good phone fro the LG V70 or LG V80.
Any Verizon, T-mobile (and Sprint), and AT&T MVNOs (Straight Talk, Ting, etc.) will also be affected by these decisions.
I have a more extensive discussion of this issue here:
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?

Hello!
Can someone please help me with this?
Everything was fine until 2-3 days ago. When all of a sudden I was unable to send text messages or make phone calls. All the while I could access internet without any issues.
If I switch to 2G or EDGE for the Subnetwork, I can make calls and send SMS.
How can I fix this?
Could dropping the phone have caused this?
Dropping could certainly break something, of course, but let's assume that's not it.
What carrier? Is the phone officially supported by them (ie, IMEI matches the carrier)? Are you on their official ROM? Does/did your VOLTE work (before and after the "few days ago")?
Some carriers are switching over to VOLTE-only setups, so they may be testing that to see what works/doesn't before they make it final. In other words, maybe your phone is not "officially" supported by VOLTE on the carrier, which is why it's failing? Without VOLTE, I think text may fail as well (even if you're not actively on a call?)
That would be my first guess. In my case, for example, I was on a US998 phone (per IMEI) running VS996 on Verizon. Since the IMEI didn't match a VZ phone, they refused to say it was compatible (even though it worked fine for many years). The IMEI stuff is a bunch of BS, but that's a whole separate topic... but I wonder if this is what you're running into. It's the carrier's way to force you into "their" device, even though it's not any different from any other variant (when the proper ROM is installed).

Carrier texts should theoretically still work as they are "data". It's the "voice" part of VoLTE that won't work. That's why I can still receive carrier texts on my Galaxy Note 9 with AT&T -- which still has older firmware (so I can be rooted). A few months ago, I lost the ability to make/receive phone calls on my AT&T number when 3G towers were decommissioned in my area... But luckily I have Google Voice number, which also uses "data" (VoIP) so I make/receive all my Google Voice phone calls. (That's been my main phone number for years.)
However, I no longer can make/receive AT&T phone number calls -- which is fine. I switched Google Voice settings to data/Wi-Fi only instead of piggy backing on carrier phone number. Yet, I still receive AT&T texts, which is good because my bank insists on using a "real" (carrier) phone number for SMS security code confirmation.

I'm with a company that uses T-Mobile towers. I connect just fine with 4G LTE, and get reasonably good speeds over it. But when I'm on 4G, I cannot make or receive calls or text. It says Emergency Calls Only.
So far, I've tried everything. I resettled network. I looked for different APN values that may fix the issue. When I couldn't think of anything else, I did a factory reset. (I mean, I wiped Data, and all other partitions in TWRP except for System and SD Card.) There have been no changes.
I'm starting to think the issue may be hardware, I did drop the phone a couple of times the day it stopped working. Though I usually end up dropping the phone once a day or every two days. I can't believe the screen hasn't cracked yet, at all. Could a drop from 3-4 feet on hard surface like tiles damage the antenna in such a way that only 4G data works?
I'm ready to give up and buy a new phone even though I can't really afford it. It would be awesome if I can get this to work.

I'm on T-Mobile towers with the US998. I don't think there is an issue with IMEI. How would I connect to data with 4G if that was the case?
I never had Volte on this phone. I do recall seeing it when I first got it but I'm running stock rooted Android 9.
When I say it used to work a few days ago, I mean it just stopped working at one point. I wanted to make a phone call, and all of a sudden, I couldn't. I noticed then that it says Emergency Only sign, so I walked around the house for about 15 mins to try to get signal. Then I went to my car and drove around, but nothing.
I messed around with Network settings, and figured out that Voice and TXT worked when I switch to a lower 'Sub-Network' setting that says, "GSM / GSPR / EDGE Only".
To get 4G Data back, I have to switch it back to "LTE/Legacy 3GPP multi"
These two are found under "GSM/UMTS Settings", after clicking on "System Select" in "Mobile Networks ".
I want to also mention that my carrier website has been talking about a data migration that would affect phones using their old SIM Card.
When I saw that, I called them and had them send me a new SIM. I thought surely this must be it, but the new SIM works exactly like the old one.
Perhaps the migration or whatever it is they did that required new SIM cards just doesn't work well with my phone? Even though, before putting the order in, the rep I spoke to did check my IMEI and said that my phone is compatible.
Agreed, it doesn't sound like an IMEI issue.
FWIW, I showed a 4G connection on a phone (I don't remember if it was my V30 or a Galaxy S10+ that I was going to replace it with). On that phone, at one point, but there was no actual connection. So, the indicators aren't always accurate. That's why I thought maybe the data isn't really working, and if data isn't working then VOLTE won't work... and with many of the carriers switching off non-VOLTE calling, that could kill the ability to make calls?
In your case, you said data worked... but if VOLTE was never enabled, and the carrier dropped non-VOLTE, then, again, you may lose calling.
In any case, these were my theories. I think you're on top of the situation but I don't have any other ideas for you to try...
Instead of buying a new phone, have you considered installing and setting up Google Voice, as ChazzMatt said? I recently had to do that because AT&T's 3G shutdown meant that I could no longer place or receive calls. My quick guide on doing that is here: https://forum.xda-developers.com/t/...-based-custom-roms-when.4138223/post-87342453
I don't know why you can't also send or receive texts, but the Google Voice app has the ability to do that, so maybe try using that after you've set it up.

There's been reports T-Mobile which is now merged with Sprint has borked the ability for VoLTE/VoWiFi calling on US998 firmware phones (native or Frankenstein'ed). Apparently they only allow it now on T-Mobile H932, whereas pre merger they were happy to give VoLTE and voWi-Fi calling to "US998" phones
First, it was reported with new SIM cards they were distributing earlier this year. Then people who kept their old SIM cards found they didn't work after a forced "security update."
This seems to have also trickled down to the T-Mobile MVNOs.
This is why we told someone else recently they should probably convert their phone from US998 on T-Mobile to Verizon VS996 firmware.
Then get a Verizon sim card or Verizon MVNO SIM card, and activate it in an old cracked screen Verizon phone off eBay, then put that already-activated SIM card into their "VS996" V30.
They will have VoLTE and VoWi-Fi calling.
Alternatively, if you really want to stick with T-Mobile network, you can do what @osprey00 suggested -- which is get a Google Voice number and use it as a tool to forward your carrier calls to it.
You can read his post, see his experiences, and see if this would apply to you.
For ME -- I've been using Google Voice for the past 10 years as my main phone number. I ported my carrier phone number at the time to Google Voice. Then got throwaway carrier numbers (whoever had cheapest plan) but never gave those to my friends. To my friends nothing ever changed. I've had the same "number" for the past two decades.
But within the past couple years, I had to start giving my bank and my cable company my carrier phone number for SMS security codes. Very annoying, because in the past they used my Google Voice number to text me with no problem.
So, even though under my current firmware (on my rooted Note 9) I cannot get carrier phone calls, I still have LTE data. And with the LTE data, I can use Google Voice (calls and texts) because it's VoIP. I also get AT&t carrier texts, as that is also data. It's just AT&T phone calls I cannot send or receive.
AT&T deactivated the SIM card in my native US998 V30+ and sent me a replacement phone, which is a Samsung Note 9. I'm staying with AT&T for a reason. Otherwise I would probably pull the "V30" Verizon trick also.
I bought both my wife and my elderly mother 64GB V35 phones -- which is basically an upgraded 64GB V30. (They previously had native US998 V30.) AT&T gives V35 VoLTE and WiFi calling, and for them there was nothing new to learn.

I think it was a hardware problem, honestly.
No matter what I did, I even tried different ROM to ensure I didn't mess around with root settings and somehow enabled or disabled something that I should not have. I tried flashing stock radios, and no, nothing would fix it.
I took my brothers phone to see if the SIM card would work with his phone, an unlocked Google FI phone. As soon as I installed the SIM, and booted up the phone, I could tell it was working perfectly even on the lock screen. Right away the status showed the name of the wireless company, and active 5G data icon on the status.
I must have damaged the internal radio or the LTE data modem when I dropped the phone last. The screen of the phone never broke even though I dropped the phone countless times, though the back glass has cracked lines all over even if the surface is still smooth and the phone continued being waterproof (I tested).
Anyway, I have since bought a new phone and the Data/Text/Talk all work perfectly on it.
I'm not sure what I'll do with this phone, as selling it wouldn't be ethical. And I doubt anyone would buy a phone with the warning that service may not work.
Ah well, I may just keep and use it as a test device.
Thanks to all who tried to help.

tried a rom on a j7 2015 because android 6 is going to be left and I only get emergency calls on lte and on 3g, no problem. It's not imei problem maybe exynos processor. I went back to 6.0.1 and no problem with 4g lite. By the way, I'm not in the USA.
