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
Hello all, I'm hoping someone can shed a little light on an "interesting" problem I'm having with my new phone. This may be my first post on here, but I have scoured this and other forums trying to come up with an answer but alas have found nothing, so here goes:
I am currently using Simple Mobile which operates on T Mobile's network. I have near-perfect signal at home but can't seem to use the damned thing for Facebook, Tapatalk, Zynga games, internet, etc without my interent connection timing out on me. I recently switched from Comcast to Dish Network and no longer have wifi at home so this is killing me.
This phone screams on wifi, and it seemingly works fine everywhere else via my data connection except at home. I normally show an H or an E at home. From what I understand T Mobile is replacing all of its edge circuits with HSPA+, so I'm thinking they just haven't got around to upgrading the tower closest to my house as of yet. I decided to get my girlfriend prepaid service on T Mobile with that $30 per month 5GB plan through Walmart and slapped the sim in my old Motorola Defy and it works great. However, if I put that same sim in my phone I'm back to square one with the same data connection problems, so I know this is not a problem with Simple Mobile (plus like I said as long as I am not at home my phone works well, too.).
So here's the real kicker -- if I use the PDANet+ app on my phone and turn on the wifi hotspot, it works just fine when I connect using my home desktop computer! This is so aggravating, why would I time out with my data connection for my own phone but as a hotspot it work flawlessly??? I'm pretty close to giving up on T Mobile because what good are they if I can't get a data connection on the phone itself at home?
Also I should mention that all of the APN settings are definitely correct. Perhaps there is a baseband selection that I can't find somewhere in the Blu Studio 5.0 d530 that may help (I know there's one in the Motorola Defy). Maybe it's because T Mobile recognizes that my phone is not a T Mobile branded phone (but the Defy IS), and if so, how can they push the whole "bring your own phone" thing so hard?
In any event, I may try just switching to Straight Talk but I really don't want to go through the hassle of porting my number and all that -- plus I'm not sure how good their signal is in my area. A search online for closest cell towers to my address results in T Mobile by a longshot.
Any help is appreciated, guys -- I'm frustrated to no end here.

Use Google Translate, if needed. Basically it just says that is the stock 4.1.2 rom with no carrier bloat.
to day I stated to have problems with my internet on my SGP621 LTE I'm on T-Mobile and i'm getting the connect me messages basically t-mo want's me to get a separate tablet data plan. I was wondering if there is a work around so that I can use my tablet as a regular phone with data internet access without an additional data plan which I would not pay for. is there a way to make my tablet SPG621 to show as the regular Z3 phone and not as a tablet so that I can use the internet 3G/4G LTE thank you:crying:
I think that's just an offer. You don't have to do this. As far as i know you can use your SIM in any device you like. And ... Xperia Z3 Tablet Compact can be considered as a big phaplet.

I agree with nico_las. I use my SGP621 on T-Mobile USA as well, and it's not mandatory I switch over to a tablet plan. It's just an offer you can refuse.
Is there a way to refuse this offer? Like, my data no longer works as of maybe two hours ago, and I am not the only one reporting this. Can I refuse an offer and retain it? I called 611 but as usual the pre-paid support folk never know anything outside of their scripts...
the problem is that t-mo knows is a tablet and the internet wont work, calls ant and text does work but not mms and everything that requires internet, if any body know how to disguise as a phone/phablet like the z ultra by modifying the IMEI or something. thanks
Yes, I am currently Experiencing this Issue as well, and I told T-mobile Rep to stop forcing people like this. I can just sell this phone and buy a note 4, with smaller screen and it will work just fine.....but they basically want to force people into it, so they can make money out of it.
I am interested in how to disguise the tablet as a phone as well.
I really really want to kick Tmobile in the ass and never come back as a customer........but they know other carriers do the same thing......We are at the losing ends
we need to ask to devs if we can get help on this issue. what we need is to disguise out tablet as phone or phablet
I think you're being overly optimistic. I appreciate it. But we barely have support enough on this device to get a proper root, much less ROM support. I feel like it should be possible to pass this off as a normal Z3... But not sure. In any case it will take root at minimum and most likely an unlocked bootloader... Which I don't plan on pursuing until I know I can keep remote play, DRM, cast support, etc.
I hope it happens... And I'm with you... But I think it's a lost cause. I'd like to hear from an actual Dev about it though... Just not a lot of them in the English world with this tablet not on shelves outside of Asia.
Hey guys, a few thoughts.
First, there is chatter about this in 3 or 4 different threads. It doesn't have to be this thread, which I created yesterday, but we should band together and use a single thread for longer-term discussion.
Second, I actually don't think that this is an attempt by T-Mo to gauge more money out of us; we are a tiny percentage of their user base and are probably an attractive demographic for T-Mo in a sense. This is simply bureaucratic disorganization (I think they simply don't know how to provide 'free data for life' without considering the 621 a 'data only device,' damn you all who rallied for that), and unfortunately execs are not going to make an immediate priority of satisfying a tiny percentage of prepaid customers on cheap plans. What I personally expect will happen at some point, T-Mo will act in accordance with its 'uncarrier' mantra and be the first carrier to recognize that there is increasingly no difference between a phone and tablet. They will offer substantially the same plans for any data enabled device and will be the first carrier to officially support "phablets.'
Third, I am also very curious what can be done to trick T-Mo's system, in the mean time. I can say firsthand that altering the device model # inside your build.prop file will do nothing. Switching up the APN, nothing. But I didn't personally get that creative before giving up. One thing to note, on an older device, I downloaded a root app to ltyer my DNS servers (switched from T-Mo to OpenDNS). Within X many minutes of rebooting I could not make phone calls or receive texts and no data icon appeared either, but I did have data and T-Mo was probably unable to meter my data usage. Try at your own risk.
Fourth, *****ing accomplishes nothing. The great thing about buying unlocked, is the ability to switch carriers at the drop of a dime (which is coincidentally what T-Mo deserves from us right now). AT&T has LTE on four frequencies and the 621 supports all of em. I already made the switch to AT&T, and everything is smooth at the moment. And I can always switch back. As a light talker I miss my $30 plan (and the small $$ I had left over in my acct), but $60 for talk, text, and a tetherable 4 GBs of LTE isn't terrible when you can buy 5-10% off discounted refill cards from Calling Mart. Cricket is also on AT&T's network now and $60 will get you 20 GBs of <= 8Mbps LTE, $10 more if you want to tether without worry. I would be curious for an expanded discussion regarding our options, since I am only so familiar with the ins, outs, and possible pitfalls of them.
good one
Would anyone like to test for compatibility/pitfalls/etc on Harbor Mobile? $50/mo for unlimited talk/text/LTE and 3GB tethering on T-Mo's network, purportedly.
https://www.harbormobile.com/plans/
They also have a good looking tablet data plan ($15 for 5GB) that would be more useful if we had dual sim slots.
MetroPCS would be the other competitive T-Mo pre-paid option. Not sure how these companies detect phones/tablets. They don't offer free data for life, which might or might not make a difference.
Possible Solution?

I work for T-Mobile and have also have the same issues with my Z3tc I, being a store manager, have limited resources available to me but i plan to submit a ticket in hopes of resolving this issue, it would help if i had multiple issues to report however. If you folks are willing to help me out with this (power in numbers as they say) i think we may have a chance of getting a fix, what i need from each of you is your T-mobile telephone number that you've been using your Z3TC on and i can submit this ticket. Email your name and phone# to [email protected] and I'll do my best
I was about to e-mail Tyson, and just saw this posted (by a post-paid customer) to a T-Mo Support thread I had participated in:
"Just got off with customer service with the solution. To fix the problem you need to get a new sim card. The customer service rep said T-Mobile will provide them for free then everything should work fine. What happened is the info on the sim says its a tablet, once the sim info gets changed on T-Mobile's end there is no way to change it back and the only solution is to get a new sim card. Hope this helps you guys."

I don't think this is correct. I already got a new SIM for mine because that's what Tmobile support had me do originally. It didn't fix the issue. However I noticed under my account that it had my device listed as a Xperia Z tablet as in the old version when I got the new SIM. So maybe if you change it to a Z3 and get a new one it will work... But I doubt it.
The tech support I most recently talked to said they updated their systems with the Z3TC information and classified it as a tablet so the data won't work unless you get on a tablet data plan. But if I get on a tablet data plan then I can't have phone and text on the same SIM. He said there was no way for them to accommodate both.
And I tried explaining that the only difference between tablet and phone is phone capabilities... Which we have... So it should be a phone.
I see that more and more people are having this problem and being that t-mo knows that our SGP621 is a tablet the only thing to do is to disguise it as something else other then a tablet. I know that phablets do work fine like the xperia z ultra. we need some technical help on doing this guys.

I've got about 5-6 people's info so far, if i could get 10 or so i think we could make some headway here. I have tried SIM swaps, tried using a regular z3 for a couple days and switching back, tried rooting and IMEI changing nothing has worked thus far... this seems like the best chance here.

This won't be a problem on AT&T's network. Why not just switch? For high data users, Cricket has competitive prices, for low use folks there are several mvnos to choose from.

Does anyone have an update on this? I think I got hit too. My internet stopped working this morning and I've been calling T-Mo and they said they don't know what the problem is.
I have an Samsung S9 Plus that was an AT&T unit (I think) and I flashed it over to the global firmware so I could use it on Visible (Verizon). It has been working for months, but I have now had this problem happen twice. I get up on a Monday, and notice that my phone has no service. I think it says "No Network Connection" or something like that. The first time I tried many of the usual steps - switching airplane mode, resetting network, wiping the cache, long support chats with Visible. What finally got it working again was putting in another sim(from Red Pocket - AT&T). That made the phone go through a reboot to swap over to the new sim. Then I put the old Visible sim back in. The phone does another reboot, and now everything is working again.
Is there a way that I can get the phone to go through this process without swapping the sims? I would just like to know if there is a more efficient way of fixing this problem when it pops up.

Call your carrier and have them to a reprovision. I had this happen with T-mobile coming from Sprint.. They will have you turn off the phone, do something on their end, and after that it should work.
Just to update, I have switched over to ATT Prepaid. Since the change, I have not had the problem happen. I think it must have been an issue with Red Pocket. Either that or something that got fixed with an update. Just putting these data points out there for anyone else that is having issues like this.
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.

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 ".

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.
