[Q] Just bought a used T-Mobile Note 10.1 - Galaxy Note 10.1 Q&A, Help & Troubleshooting

As the title says, I've been dying to get a Note 10.1. I finally got one but it happens to be a T-Mobile version and the sim card has been removed. I don't plan on getting 4G service ever if I can avoid it.
So now I have a few questions:
1. Will I be able to get updates like the wifi only tablets do or will I be forced to get T-Mobile service when updates come out?
2. I have these annoying notifications about the missing sim card. Is there a way around this? I have Sprint service for my phones so I really don't know much about sim cards. Do I need to go to T-Mobile and just ask for one to pop in without getting service? Are they free or would they send me packing because I don't have their service?
3. I also have the x'd out signal meter that I would love to get rid of.
Any advice you guys can give me as a sim card/carrier tablet noob would be very helpful.
Thank you

If you're rooted, you can use xposed mods to do almost anything to the tab you want. As for updates, I'm not sure about since I have the 8013 and Samsung has said fu to it.

if you are running stock rom. I would go to amazon and Order a sim card for data devices. I think you can get one for like 14.00 with 1 gb data PRE PAY. setup t mobile account and then change your plan to pay as you go DAILY . Your sim will not expire and if you want or need to use the devices on there network even once a year you can just jump on there site and buy a day or weekend pass.I have not checked this lately so the above cold be slighty different now. Good Luck

[Q] Android prepaid sim card issue, Sharp FX Plus asd1

Hey all, my mom just got an unlocked AT&T Sharp FX Plus asd1 android 2.2 phone to replace her old phone. She uses AT&T prepaid service so when I was setting it up for her I just used my T-mobile sim card with a data plan which worked fine but when I put her sim in all I get is a sim card icon in the notification bar with an exclamation point. But the weird thing is not only is it an AT&T phone but it came unlocked and I rooted it I even did a factory reset but still nothing. Her prepaid sim card works on my rooted T-mobile G2 no problem I'm not really sure what to do she could I suppose get a tmobile prepaid sim card but I don't want to have her buy more stuff for something she may not be able to use. I thought of updating it to 2.3 like my phone but besides rooting it there is little in the way of development I really don't wanna have to tell her she's gotta sell it to get her money back. This shouldn't be that hard I've done stuff like this b4 with no problems what so ever am I missing something? Any info you guys could give me would be awesome and thanks in advance.
Call att and tell them you are changing phones. They have been locking sim cards to IMEI as of late.

[Q] Verizon Samsung Galaxy S3-SCH-I535-Unlocking

I am by far no where near the caliber of technology that lie within this web site, however, I am simply trying to get some direction regarding my S3.
I purchased it from Verizon-2 yrs ago, contract expired 7/8/13; did not renew. I went with Consumer Cellular (more fitting for the older generation) but my S3 WON'T WORK ON THEIR NETWORK!
I have spent the last 3 weeks doing research on this phone to see if it can be 'unlocked' to work with a another carrier. The phone is like brand new and I don't want to get rid of it, I'd prefer to use it with the new carrier.
Is there anyone who can give me some direction to this issue? Can the phone infact be "unlocked' to work with Consumer, it has the Verizon SIM card in it, I was able to root it, successfully, now if I can just get it unlocked. Had to purchase another phone so that I would not be without phone service while I work on trying to get this one unlocked.
I've been told it can't because Verizon is a CDMA carrier and Consumer is a GSM..if this in fact true than I've no options but to sell the phone.
I do have "Preferred Network Mode' and it gives me the following options, Global, LTE/CDMA & GSM/UMTS.
Any help, directions or information would be greatly appreciated. With my thanks to all those who have taken the time to read this post.

How did you get this phone 2 years ago? It barely came out a little more than a year ago.
Next, you can unlock it, but only if you pay for the full retail for the phone and then contact Verizon about what you want to do and then get an unlock code. After that, you're going to need a SIM card from Consumer Cellular.
There shouldn't be a problem with radio frequencies since the Verizon GS3 is a global phone. So the SIM card should work after you get it set up.
If I'm wrong in some aspect, someone feel free to correct me.

In regards to Unlocking the phone, the phone is unlocked out of the box, you just pop in your sim and select GSM mode! you have to set the APN for DATA yourself tho!

Hi:
I do not recall the date of purchase but know that when I purchased it I had to sign for a 2 yr contract with Verizon..that contract was up July 8,2013.
That is not important, what is important is to find out if in fact the phone can be unlocked, VERIZON swears it is unlocked so they are not going to be of any use to me to get their help. It is up to me to find someone who can unlock this phone via a cable. The code places I have contacted can't come up with a code, they have instructed me that it needs to be done with a cable.
As I stated, I am simply trying to get the phone unlocked to use on Consumer Celluar, of which I am already a memeber and have the SIM card activated on another SAMSUNG phone of which I had to buy.
I do not have to buy the phone outright, as the phone is paid for, thus the 2 yr contract. the phone is mine, but as long as it is in the state it is now, I can only use it on VERIZON.
The I535 has a sim card in it from Verizon, when I take out the Verizon SIM card and put in the Consumer SIM card I get the message, "this is a non verizon SIM card.
I am researching this everyday to find out if IT CAN BE UNLOCKED, AND #2 WHO CAN I GET TO UNLOCK IT? Verizon went so far as to tell me that all the person needs is a USB cable and PC...how true this is, I don't know.
Thank You

Verizon is right by saying its unlocked, and thats the most anyone can help you, if you are going to try unlocking the phone by cable, you might as well throw money down the drain! and 2 you need to update to the MF1 software! as MB1 and MD3 would tell you its non verizon sim card, but even on that update if you put the phone in GSM mode in Network settings the phone should work fine for calling and texting!
having the same issue, if you find out anything will you please let me know how to do this too. i would greatly appriciate it
SIM
Did you get the free Consumer Cellular SIM yet? Your post said you have rooted and have the Verizon SIM, and you can't get on CC network without their SIM card.
The phone is already "unlocked" for global/GSM use with the JB update, so you should be able to just pop in a SIM card from CC and change settings (they should provide you with this info).
A lot of ppl are saying the Verizon GS3 is already unlocked, but when i pop in my metro pcs sim card and switch network to cdma, nothing happens. What would I have to do to make it work with this metro carrier?
No Data, No Voice, No SMS
Hi. Im also having the same issue. I have a Verizon GS3 that was originally running 4.0.4, VRALHE. I rooted, updated the baseband to MF1, and installed RLS16 of Hyperdrive, so I now am on 4.1.2. I have the option to go GSM or Global, but when I put in my MetroPCS sim, I get nothing. It prompts me for Global, but I cant make calls or send sms. I also put in the APN and no data as well. Anyone know whatbI should do next? I have an IMEI, it doesnt appear to be lost, and I have tried the phone info app, as well as trying to go through the secret menu, the network lock menu is blank.
Hey, I got the same problem, and considering how it's been a while since the last post I wonder if there is any new news on this front. Thanx!
P.s: It came preinstalled with 4.3 stock, not rooted yet. I have the option to instal 4.4.2 via Kies {PDA:NE1 / PHONE:NE1 / CSC:NE1 (VZW)}.
Update here:
I digged into some settings and found that switching it into either Global or GSM seems to make the phone capable of voice calls.
Idk about 3G, I did manually type in the APN settings, but I never use anything other than wifi because internet here is expensive unless you go with one of their plans.
So if you haven't tried it, on 4.3 go to settings, under wireless and networks select 'More Settings', Mobile Networks, Network Mode.
Worked for me, although I still get "Non-Verizon SIM" in the notifications bar and it looks like my signal is a bit weaker than before. But still works.
guys you are wrong
guys there is no way metropcs, Boost mobile or sprint networks Work cause these are CDMA carriers and verizon and the other CDMA Carriers has a different activation way on Verizon smartphones the GSM module(gsm networks as well) come unlocked for foreigner carriers even the GSM US carriers(AT&T or TMOBILE) sometimes doesnt work hope that info help

[Q] SIM Unlock Rooted and Custom Flashed Verizon SCH-i535 GS3? for MetroPCS

Hello whats up everyone, I'm in a need of help this evening!
After doing much heavy research i still have not been found a 100% concrete wat to unlock my verizon SGS3 so that i can use it with other sim cards such as MetroPCS or T-Mobile
I currently have it running EZ-Unlocked and rooted with CleanRom 4.1.2 when i put in a non verizon sim such as a non-activated T-Mobile card, it doesn't say "sorry, this SIM is not supported. please....." but says simply no service. Is my phone already SIM unlocked?
I also saw this handy method:http://www.youtube.com/watch?v=-cmiEZcw1z8
but when the NETWORK LOCK option came up..it just said NETWORK LOCK and no 3 options I could choose..hmmm
EDIT: heard that 4.1.1 HAS the option to get rid of the NETWORK LOCK option and this feature was apparently removed on purpose with 4.1.2? But i'm running CleanROM?
BTW: i've tried "galaxsim unlock" but it's not compatible with the US Variant yet.
MetroPCS will get my phone working on their network and do all the trickery...I just need to know if my phone is SIM unlocked.
BUMP: Look Guys, I've seen quite a few people view this with nothing to say...It's URGENT. i can't afford a new handset and verizon is cutting us off for good because my girlfriends cousin who was also on the plan that her mom was on the name for...went over on data twice. Her Cousin doesn't live with us but was on the plan...he was suppose to be grounded for going over the FIRST time but fooled his mom into giving her the MicroSD card and lied and said that was the SIM card. so he went over another month probably downloading porn and ****.
verizon said there is no rush to pay the overages....as we will not be turning back on service. We use our cell phones as the priority communication tool..no home phone....right now we have no provider. I need an answer please

[Q] Getting LTE on AT&T w/ Nexus 5

Hello,
I'm coming from a Nexus 4, and have never had an LTE phone on my AT&T account before. I've read that since AT&T doesn't have Nexus 5 in their system, that it will be a hassle for them to activate LTE through the phone. I can't really find any concrete answers or info, so I figured I'd stop by here and see if anyone has any ideas?
Does AT&T have to activate LTE on their end for it to work? Or can I just adjust my APN once I get the phone?
Has anyone had any issues with this at all? How did you get around it?
Thanks in advance!
I would like to know too... Im thinking about switching over my corporate account from VZW to ATT and I ordered a Nexus 5 to try out ATT coverage in my area first. I was going to head into the ATT store tomorrow, now Im worried I won't be able to get it setup (Im not familiar with how ATT works). Do I need to get a IMEI from a phone in the store and give to them? I don't get my N5 until tomorrow night and I was planning on going the store tomorrow morning and getting either Gophone or shared plan SIM setup so I can pop it in when the phone arrives. Will they need an IMEI to even get me an account activated?
If they need an IMEI at activation, would it matter if I didn't have the device in front of me, like if I tell them I ordered a S4 and gave them a IMEI from one? Do I need to find someone on ATT to give me their IMEI and tell them at the store I have it ordered? Sorry if these request are way off based on how it actually works, but I want to be able to test out my N5 tomorrow night! Thanks for any help you can give me..
EDIT: In the ATT world, would It be considered shady for me to tell them all this info? For instance if I told the salesmen this problem and asked if they could use an IMEI off one of their phones?

I'm assuming that this will work similar to how it worked for the N4 and enabling HSPA+ on AT&T.
You will need an LTE plan added to your account. It won't cost more, but the account needs to enable the LTE service. In order to do this, I believe AT&T will need an IMEI. Since the IMEI will not be recognized, then you need to get another AT&T LTE device's IMEI code. Maybe a friend? I know some people would copy it off a demo device in the store.
Good luck.
FWIW: I put my LTE sim in the phone and everything was autoenabled correctly. This was better than with the N4 where it autoenabled wrong, and I had to change the settings.
I'll clarify this, AT&T has different data plans. They have all their data plans for 3g phone (3g data unlimited), and all their 4g data plans. You can not get 4g unless your data plan has been switched to the 4g version. You can keep your unlimited plans with this. Just call and ask them to switch your data plan to the lte version.
Sorry double post

So, to clarify, did you just activate LTE with an N5 coming from an N4 and it went smoothly?

i'm in the same boat, i'll know for sure when i get the n5 tomorrow but from what i've seen AT&T does have to provision your SIM for LTE. My plan is to goto an AT&T store and ask them if they can get my sim sorted; if they screw around or say they "can't" help me then i'll either grab an imei from one of the demo phones or from a buddy and call them and give them that.

This looks to be the thing to do. I just had someone inform me that they brought the phone into AT&T, and the guy punched in the numbers off the sticker on the back, gave him a sim and he was good to go. I'll make sure to come back here and report my own findings first hand since this question seems to be floating around a bit.

Do identical IMEI numbers conflict if its already on the network? Can I use the same identical IMEI from a friends ATT phone or do I need to change some numbers?

I already had an LTE Sim. I just used the LTE Sim in my n4.

College Station, November 4, 2013 Verified - LTE addon
I can verify coming from a "Nexus S" BYOD.
I went to an AT&T Store in College Station, TX to get a new microSIM because the Nexus 5 only takes microSIM form factor.
I then got an LTE signal, but no IP address.
Chatted online and they told me to wait 1 hour then reboot the phone. Did so.. same response, gets on the LTE network fast, but nevers gets an IP address.
So I then called 611 on the Nexus 5 and talked to Tech Support, told them:
1. I have never had an LTE phone before and thought I needed LTE service added to my Account Profile.
2. I wanted "No changed to my legacy Unlimited plan"
They told me
1. My "legacy Unlimited plan had just been removed by 'mistake' and would have to be restored by the (backoffice)"
2. They were updating my account to enable LTE service
I then had to reboot the phone, did so and the Internet service came right up.
Now I have to wait up to 72 hours for AT&T backoffice to confirm they have restored my Unlimited plan.
I put a pass-code on my Account, and strenuously stress every time.. DO NOT TOUCH MY UNLIMITED PLAN !!!! -- And they do it any way.
.. exasperated ...
They also do not know what a "Nexus 5" phone is yet.. so I think only the call in Tech Support can interpolate what to do. I think the kee was to keep calling it an "LTE enabled Nexus 4" and then things just "worked".

Not registered on Network...?

I gotta problem lol. I haven't used this phone in over a month because I destroyed my LCD. So when the new one came I put it on and the phone was okay... Well until it kept saying about me not being registered. I mean I looked everywhere and my phone is unlocked and I'm using TMobile. But it only gives me the voicemail notification and that's all. My signal been going in and out. and I just flashed a new rom (s8/s8+ port). I don't really know where else to go from here. I can't call or use my data or anything. 3days out from going back to school and still don't have it fixed... I need a second opinion before I will decide to go back to a stock rom then get root back.
Could be just something minor or...
I've got TMobile... (Well mint sim) they said that my sim card is purged and that they needed to update the Sim card or they'll send out another if nessacary. Hope they'll fix the problem.
Min and Prl is Null..
I'm guessing it's no longer the Sim card that's causing the problem. I still need help
Hey guys sorry for posting here but I was wondering if it's possible to use a sprint note 5 on Verizon? I'm thinking about getting the note 5 but I want to be able to unlock the bootloader and root. Only issue is I have Verizon. Any suggestions on which version of the note 5 I should get?
Thanks

Did you ever get an answer for this issue? I have a rooted Sprint Note 5 and switched recently to Verizon. Everything works right except my signal says roaming perpetually. That said, I am getting a data signal but I don't think it's up to snuff as far as 4g LTE. The way we got it going was the rep activated a SIM card with another phone before dropping it in mine. I had no data for a while but eventually got it to use data over mobile just, as I said, not full capacity mbps of LTE. I'm hoping to fix the signal saying roaming so I know if I have a 3g, 4g, LTE or whatever rather than just "R" and never being sure if I can access data over mobile with it being hit or miss. Any thoughts?
