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.

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
What's up everyone.
Quick question to see if anyone has tried.... If I put a T-Mobile SIM in the OPX and a Verizon SIM as a secondary, I'm wondering what will happen?
I have a work phone and a personal and am tired of carrying both. I need the Verizon SIM to get ONLY phone calls and text messages. I don't care about data. That's what the T-Mobile SIM is for. Also, how would the OPX handle phone calls? Will is ask me each time I make a call which phone number to use?
Will this work? Anyhone tried it? I've got a OPX on order via eBay and should be here next week. If no one knows, I'll have to post back.

I dont think the OPX supports CDMA networks... Only GSM and even that is not fully supported.
Well, I received the One plus X on Monday and have had a few days to play around. I am truly impressed. The build quality is fantastic and it the PERFECT size for me. Slightly larger than the iPhone 6 but a 5" screen. With respect to signal and T-Mobile Bands.... I haven't run into any problems here in Southern California. LTE everywhere.
Unfortunately, my simple experiment of getting verizon voice and text setup as a second SIM did not work. It does detect the phone number but no service. Oh well.
If you have an old Verizion (USA) unlimited data plan (or perhaps other "older" phone plans) that you've been holding onto AND you plan on buying unlocked phones you may want to read about what I learned today... This is mostly a PSA, but if anyone knows of a way to actually "fix" the issue please reply.
The short version is that apparently the old (original) unlimited data plans are setup to only work with locked down "Verizon" phones. I'm still working out all the ramifications of this and could use some help further down in this thread. What this means is that you can NOT activate a NEW sim card in an "non-Verizon" (unlocked) phone IF you're also on an original unlimited data plan (and perhaps any other older plans beyond a certain date?). You CAN; however, activate a NEW sim card in an OLD Verizon phone and after setup is complete you can then move that sim over to your new phone. This should not be a problem for NEW Verizon phone plans OR locked down phones that are considered "Verizon phones" by Verizon software.
As far as I can tell (so far), activating a new sim in an old phone and then moving to the new phone doesn't cause any issues with your service, but I could use some help testing this out in greater detail to confirm.
Here's my story:
I've been on a Verizon unlimited 4G data plan since they first offered them many years ago. I've remained on this plan through price increases and the removal of unlimited only to watch them return it (I almost switched to a new plan months ago... almost). I used to have a Droid Razr Maxx which got rooted and I enjoyed root for awhile. I eventually upgraded to the Droid Turbo (employee edition) which took a long time to gain root so I simply never tried. I decided I wanted root access again and all the joys that brings so after much research into my next phone I landed on the LG V30 unlocked edition. I got my order from B&H Photo a few days ago. I also decided that I wanted a new sim card as I've always felt my old one was "touchy". Could never put my finger on, but mostly I just wanted to start fresh with the V30.
A couple days ago I went into an official (USA) Verizon store and made my request to get a new sim activated on my V30. I didn't think this would be an issue as they sell V30s and I know others have been running "non-Verizon" phones without issues. The CS rep was supportive of this, but after inserting the new card and trying to activate it the Verizon software on his employee tablet shot back something about "this phone does not support this data plan" (or something similar). He tried to troubleshoot the issue for about 10 minutes, but then gave up since I was able to get the V30 working by using my old sim from my Droid Turbo. I accepted this and decided I'd just try again in a few days.
During this time I had no issues with the V30 using my data or making phone calls. I did eventually "kill" the V30 by exploring the band selection screen in the service menu, but a hard factory restore later and I was up and running again. Today I decided to try and get a new sim card again, only this time I decided to head to Best Buy since they sell the unlocked V30 online. My thought was "if they sell the unlocked V30, maybe they'll better understand my issue with a new sim activation"....
After finding the "sim card expert" I requested we went to work. He pulled our a new SIM, dialed up his Verizon contact number and we waited. Once the Verizon rep was on the phone we continued onto activating the sim only to be met with the same error "phone & plan don't like each other". The Verizon rep was stumped after many trial and error attempts on getting it to go through. My issue was eventually escalated to a tech that had more power to get things working and even he was stumped. After nearly 2 hours of digging into provisions and my account info he informed me that my "old" data plan was setup in such a way that it ONLY allows new activations with "Verizon" phones. Of course he suggested I move to a new unlimited data plan (with all the new fine print and prioritizations after 22GB intact of course, ha). He added that there was nothing he could do to change my plan settings to allow new "non-Verizon" phones. He was supportive of activating the new sim on my old Droid Turbo and then placing it into the V30 though. Once we did that the V30 was up and running again. On some quick tests everything appears to be working as well (would like some help to verify this though).
So there's the info I learned today, hopefully this helps someone else avoid any headaches later. How accurate this info is depends on the Verizon tech on the other end of the phone though as I'm only repeating what I was told. The tech did say that he never ran into this before (as I assume most people simply keep swapping in their old sim cards) and he did add that newer plans and phones shouldn't run into this issue and that it's strictly my old plan causing the hiccups on their system. He did check into moving me to the new data plan for activation and then putting my back into my old plan, but came back with "it's not possible".
Now then... all the above said I could use some help ensuring that my unlocked V30 is working correctly on Verizon with my current phone plan.
I've installed an run "RX Monitor", but what I notice is that I see no CDMA options listed under "operator" or "registered cells" or "Neighbor cells". All I see are "LTE" connections that seemingly only use "Band 13". I've driven between different cities from corn fields to the center of town and any time I check I see only "LTE" and "Band 13". Based on what I've read this seems odd... but I don't know enough about it to say for certain.
What I can say is that I can make phone calls (though they seem to be going over LTE and using HD Voice) and I send/receive SMS and MMS texts. I can go online and download and all the good stuff.
Is there a way to further test my phone? When I run RX Monitor on my wife Droid Turbo I can see a CDMA option and other LTE cells, but her phone does not report enough data to compare (ie, it doesn't list the band anywhere in the data) that I can see.
Is there another program or some other way to test or check this? My concern is that I've yet to see "3G" or "1x" on my V30 and I worry that if I end up in an area with more limited coverage that the V30 will simply not work vs switching to 3G or lower (something my Droid Turbo has done in the past).
Any thoughts?... and thank you.

I know it was a long read, but hopefully it made sense.
With full root access would it be possible to label an unlocked V30 as a "Verizon" V30 in software to trick the Verizon registration process into direct activation?
I don't know. The two have different FCC ID, so that would be one way for Verizon to tell the difference.
On the U.S.Moto Maxx 1225, people could unlock the bootloader, then flash Verizon firmware over it to turn it into a Droid Turbo XT1254 because they had the exact same FCC ID and were exactly the SAME device. Verizon just rebranded theirs as a "Droid Turbo" to pretend it was some kind of exclusive. It wasn't even exclusive in the U.S.!
Until Sunshine came along to unlock the Droid Turbo bootloader (a year after release), the Moto XT1225 served as the "dev" version of the Droid Turbo.

I assume I'm not the only grandfathered Verizon data plan with an unlocked V30... can anyone else confirm that simply moving the sim over from another phone allows the V30 full access to the Verizon network.. CDMA, LTE, 3G, etc?
As I've said so far I only ever seen LTE with 4G. Though I did see CDMA once shortly after activation.. but then nothing
I recently got a Note 8 (at best buy, 300 off,but a down payment, and device payment plan). The sim activated on the Note 8, but my previous active sim was on an Unlocked S8 Plus (g955u1). I then activated the Note 8 Sim on my wife's back up S5, and then put the sim in my S8 plus unlocked. Inhave used the Note yet, because I dont have a glass protector yet and in case I have buyers remorse, I can return the Note 8.
If you have the grandfathered plan (which I do), you jusy simply have to get a 4g Verizon smart phone with a nano sim slot , activate it in there and put it in the Unlovked Lg v30. You should be able to get CDMA and 4g LTE connection.

Hmm I've had the same sim (just shaved down) since my OG Droid. Would this make a difference?
Ooo yeah here we go
Per Verizon's agreement with the FCC when they purchased radio band frequencies, Verizon must allow any compatible device to work on their network. If your device has CDMA and the LTE bands (2, 4, 13) then it will FULLY work. You will be able to make CDMA calls, LTE calls if VoLTE is functional on your device, and use data.
It is true that they are stingy on activation and there is NOTHING the techs can do to activate an unlocked phone. They did't write any code to block it let alone are aware of it. Don't bother even trying. Just get an old Verizon phone that takes nano SIM or go to a store and find an employee willing to activate it in a display phone then give it to you.
I've been using the same SIM for years from my Droid Turbo. It's been in a Nexus 6, Nexus 5x, Moto G4 Play, and an HTC One M8 without any usability issues.

Yes, that SIM card you have is still considered a mini SIM and will not activate in newer phones that take nano SIM.
I shaved down a micro SIM to fit a nano Sim slot. I tried to have it reactivated and Verizon was unable to. I informed the tech that it was actually a micro SIM and he activated it in a dummy Galaxy S3 and it worked.

Verizon and probably the others use the IMEI number to check if it is a VZW or non-VZW phone before activation. Unless you obtained another IMEI number and used it, they can always tell it is a non-VZW phone. But I'm pretty sure that is illegal.
I'm on an unlocked/google Nexus 6. It wasn't purchased from Verizon. I also have an old unlimited data plan. Once a stockish rom comes out for the LG V30 I'll take the plunge and test this out. Hopefully my sim will work in the v30, since it already works with an unlocked phone.
All good info. Thanks everyone.
How could I test the phone though? Is there a way to force CDMA calling vs LTE.... Also... Using RX monitor why would I only be seeing band 13 with no CDMA listed?
I'll update here what I learn comparing a "Verizon V30" vs my B&H unlocked V30. I purchased a second V30 using the Verizon $300 off deal to combine it with the $400 rebate from LG. I know, I know.. it's locked down... but for a cheap backup phone I'm not complaining. I'll run as many comparisons for cellular service as I'm able to.
I know of RX Monitor... hopefully that will confirm or deny that my unlocked V30 is using the network in the same way as the "Verizon" V30.
Any requests or other programs I should use for comparison??
From what I understand, the grandfathered Unlimited has nothing to do with it. As far as I know, Verizon has only activated NEW sim cards on Verizon branded equipment. Once your number is provisioned on a Verizon phone, there is no issue moving the sim between unlocked phones.

THIS. This is what I've always been told the past few years. Recently someone said Verizon had changed their policies and they somehow activated a SIM card on a 2015 Moto X Pure, but I think that was some kind of fluke. I would still use this policy as the guiding principle for control freak Verizon.
AT&T and T-mobile don't care where your phone came from, they'll activate your phone. I'm on AT&T and have never had an AT&T branded phone. I even brought in two Moto XT1225 from other countries; the Moto XT1225 is the "international" version of the Verizon Droid Turbo XT1254. It was also basically a 5.2" version of the Moto Nexus 6. AT&T didn't have the XT1225 in their database. I said call it a Moto Nexus 6, which they did have in their database. BOOM. Activated. Two of them. And not just on AT&T, but AT&T Prepaid, because I own my phones and only want to pay for monthly service not pay an arm and a leg to subsidize some AT&T branded phone I will NEVER buy.
I'm not here to bash carriers (but I will bash most MVNOs), but the CDMA twins Sprint and Verizon are more trouble than they're worth, in my opinion. I want to use a carrier's signal, but I don't want to buy a carrier's locked down, often overpriced, devices. I don't want to have to buy a carrier phone just to be able to activate a non-carrier phone on that carrier. That's ridiculous.
Does the hot spot work out of the box on the unlocked V30 US998 on the old verizon unlimited plan?

yes, it does.
I have the B&H US998 V30+ on Verizon, but I gave up unlimited a year or two ago. Still not on the new unlimited yet.
Are you able to get any VM notifications on this phone?
I only get garbled text messages from Verizon, and there is no VM indication.
I have to check for missed calls and manually call *86 to see if I have any voicemail.
Other than that I think it is functioning fully. However I have never seen a 3G icon in the status bar.
I have a Verizon 4G Network Extender in my house, and I get good 4G at work.

I am a Grandfathered user with 450 anytime minutes and paying for text messages still. I moved from an LG G4 to an HTC 10 to an LG V30 just fine. Popped the simcard out of my HTC 10 and installed it into my unlocked V30 and it works perfectly. I don't have any wifi calling though and I'm assuming because I'm not installing any verizon apps what so ever. I don't require wifi calling so i'm good. But it drops to 3G when it has no LTE signal just fine and VoLTE works perfectly. Hope that helps you out.

It's the same for me... just messed up text messages. I even tried to source the Verizon Voicemail app, but it refused to install... sooo... I setup Google Voice instead and after some tweaking it's working great, Google AI or whatever even gives me its best translation of the voice mail too in text form so I don't need to listen
The one thing I have noticed with Google Voice and normal voicemail is that if I let the phone ring through Google voice works perfectly, BUT if I decide to swipe the "ignore" or whatever button, then the normal voicemail picks it up. It's kinda nice in a way having two voice mail boxes... but also wish I knew how to fix that issue and force everything to google voice.

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.
So I have an issue with my current tablet that is locked to T-Mobile not getting any data using a normal phone sim. I'm not about to risk buying a different T-Mobile locked tablet or even one with T-Mobile Firmware as I have a feeling I will run into the same issue, and I can't get any clear answers about it.
Does it make sense for me to buy an ATT Unlocked S7 and use a T-Mobile Phone SIM in it then? Surely an unlocked Tablet from another carrier wouldn't get caught in the data-only SIM mess right? Or are there other ways around this issue? Ironically all I really need is data, but I need to be able to use a normal phone sim from my T-Mobile plan.
Usually t-mobile doesn't care if you use tablet plan sim cards inside phones but it does limit the usage of phone plan sim cards inside tablets.
So with tablet from popular/well known brands, no matter if it's from another carrier or a factory unlocked version, you are almost certain to be detected by t-mobile and it will either block the tablet or limit the speed to 3g speed, especially with those free phone lines with unlimited data.
You would better go with an imported tablet not dedicated for US market.
