Problem with IMEI and signal - Galaxy Note 4 Q&A, Help & Troubleshooting

Hello I bought an used ATT Note4 unlocked and I use it with TMobile. I have two problems maybe related. I have very low signal and the phone dont connect in my home and my previous phones didnt have that problem. In works in other places but you know it disconnects inside buildings and low signal areas. I was thinking in flash a TMobile modem and I think its not possible. The other problem is the IMEi that shows in settings is not the same as the sticker behind the battery so something has be done to the phone. Its possible to fix the IMEI to the real one?
Thanks a lot.

The IMEI is the digital serial number of your device - It can NOT be changed (legally) - Did you purchase the phone from a reputable source? If you did return it.

I dont know if it is reputable but it is a store that sells new and used phones. Its illegal to change original IMEi what I like to do is change it to the real IMEI and make it legal.

it's possible that the case has been changed and the sticker that you see is from another device - You CAN'T legally change the IMEI - It's just like it's illegal to change the serial number on a vehicle!
Are you certain that the device was not stolen?

The original IMEI on the sticker probably is bad. Call AT&T to check it

Haha yeah it isn't a big deal at all, its the least of my problems with this phone right now haha, trying to get root with permission denied staring you in the face is hard to do hahaha
it happened to me also...a reboot fixed it...it was weird though...it happened after i installed the new market and after reboot the # showed up but the market reverted to the old one...idk if it's connected or it was just a coincidence...
Some of the apps need to read the number from the phone for them to work properly
So this will cause an issue for sure
I have tried rebooting and it doesnt seem to fix the problem at all
It has something to do with the sim card. You can call T-Mobile and have them resend it to the sim. If that don't work just get a new sim.

Mine shows unknown number too. What are the odds of us all have an issue with the sim card? Could it just be a gingerbread or nexus s bug?
May (or may not) be the same issue....
If your phone number isn't recorded on your SIM card then android won't display a number (Stating the obvious I know....)
Just grab an old(er) phone (Sony Ericsson seem to work ok for this) and add in your number to the SIM. I think the menu option is something like "My Number".
If you search the Nexus One forums, there should be some non-crap instructions....

Might be related to o2 not sending the info over their network. I've not managed to get this to work on my N1 as of yet - will try and confirm on the S later today.

AT&T typically does not support phone functions on tablets, so I'd guess no. Although the line between tablets and phones is a bit blurred, these days.
I'm not quite ready to have a mobile plan for my tablet (and really don't need it 99% of the time). And I already have the WiFi only version. But an AT&T release might mean some better sales for the N8, and better dev activity.
If this can be flashed with a EURO ROM for phone capabilities I will be first in line. :good:
Great news....
I guess this might bring down the price a bit.
If I can get either N5100 N5110 version for under $450 and flash Euro ROMS to make calls, then put me on the line as well.

The 7.0 Tab worked fine. Pretty sure the 10.1 does as well. No reason an 8.0 wouldn't. A phone is a phone, either it has voice capabilities or it doesn't regardless of the size. The only reason tablets don't work on ATT otherwise is the strip them of the feature from either hardware or software. Might have to ditch the IMEI if I remember correctly from my 7.0

I believe the IMEI is the issue. The network recognizes the device as a tablet using the IMEI, and then won't support phone services on the device.
That's the reason right there.
I know on the nexus 7 3g version It's thought to be a hardware limitation in the radio. Also they were never able to produce a modem capable of voice. Flashing to closest compatible radio caused a baseband hard brick with generic IMEI. Obviously the N7 was also lacking ear speaker etc, however they were able to get SMS/MMS completely working with SMS using AT&T's network. I personally used it as my smartphone replacement using my SIM for data & network texting while using google voice/groove IP for my phone services. Had to enable voice capable in bools.xml to true IOT unlock the native dialer & forward calls from the AT&T phone number to my google voice.
With that being said, I think redpoint is 100% correct in saying that if it does not work hardware limitations aside, it will be because AT&T is blocking the IMEI on their network. The N7 wasn't blocked because it was an unknown device on the network but if AT&T releases a 3g capable Note you can be sure it will be logged into their system and easy to track, just like trying to use an AT&T smartphone on the mediaNET system (which I was also using for a while on the N7 with no problems for the same reason I stated above)

Yep, and backing up then deleting the IMEI solves that issue as you then have a generic IMEI that is not seen as a tablet they recognize and allows you to make calls. Its been done by many here at XDA including myself.

I have a 10.1 right now that i'm swapping SIM cards with with my phone. I use the 10.1 as a replacement for my phone when I go to school and I have no issues making calls out of it. The phone capabilities work fine on my 10.1, so I don't think it'll be an issue. I'm on AT&T

Also ya gotta take into account the fact att might not have the 10.1 on their regrestry. Thats how i was able to use my N7. If ATT registers the 8.0 cuz theyre going to be carrying it they can then block it. The international one may still be safe though if thats the case.
Edit: heres a good link where they explain and compare how Att detects devices on their network and how they can block it or change plans accordingly http://forum.xda-developers.com/showthread.php?t=1446373

who needs carrier service to make calls?
Just download GrooveIP from the market, and it uses your Google Talk Phone number to make calls on your wifi/3g/4g network...
Call quality is fanatastic, at least for me here in chicagoland...You can even make and recieve using your BT headset!
I'd like a mobile version instead of the WiFi version I just picked up this week. Looks like it may go back during their return period.

No, Well not directly since that is probably illegal but if you delete your imei the device will assign a generic one automatically that carriers dont seem to detect as a tablet or atleast a specific tablet. Infact I wonder if they even bother blocking Euro devices like the 5100 since they do not sell it.

Yup, if its AT&T branded, they will obviously have the IMEI, and they will block it from phone use.

Or you can just do what I mentioned in my last post and they won't be able to block you by IMEI since it will no longer be recognized as one of the devices.
IF the hardware and software on the tablet permits making calls.

im pretty sure spoofing the IMEI is a felony though if caught. Thats why each device has a specific IMEI.

First of all check that your IMEI is the same as the one on the sticker under the battery.
If not your IMEI is borked somehow, search here on xda for IMEI restore/repair.
If the IMEI is the same as on the sticker contact your provider and ask them if that IMEI is blocked on their network.
Cheers.

Is it normal that the phone don't work for two different provider ? if IMEI is blocked, it must be blocked in one provider not two ?
I call one of the provider, they tell me that the phone is blacklisted. What can I do ? Is there an other solution ?

Of course they block all of the providers. It would not be much usefull to block a IMEI if you just could choose antother provider, right?
If your IMEI is blocked and you have bought the phone second hand it is probably reported stolen. If it is like that you should hand it over to the police like mentioned before.

Probably a stolen phone as mentioned before It's best to hand it over to the police so they can return it to their rightful owner. Not sure what you can do with the guy who sold you the thing, though.

Should I buy it from USA or the Middle East?

I live in The Middle East and will be going to the USA very soon for a few months. My cousin works at a mobile phone repair shop(USA) and said he could get me a good offer (new or used). With all the different model numbers I'm confused about where to buy it from. I want the all around the world option where it works on all carriers wherever I go, even if I have to pay more. I would prefer the 8-core one but not sure what exactly I'm trading off or even if it's better. Also the Continent lock and the Knox thing....ugh my noobish brain can't handle this. Btw I am upgrading from a Galaxy Ace which is one **** of a phone.

Im in Dubai
& its best to buy from the city your living in cos of Warranty
if u buy here it will be unlocked phone & usa if u get from Att or T mobile or etc it will be locked phone
they say international warranty but its always a problem
get the 4g LTE quad core cos it better to have fast net than a 8core phone
USA models always have lot of built in company software which u wont need here
rest is up to you

Thanks for the reply. Just a few more quick questions please.
1) So when I go to buy the phone I actually have the option of 8-core/4-core? I was under the impression it was all 8-core since it's international.
2) In terms of rooting and Roms here on XDA, is one more XDA friendly than the other? Is there a model I should avoid?

both can be rooted
4 cores is 4g LTE which I think is better cos aster net speed
8 cores is 3g only
the way Samsung 8 cores work ATM is, that you can only have 4 fast ones or 4 slow ones working, depending on load, but never all 8 at the same time. There was talk about software fix for this, but who knows how that will turn out. The risk of buying US phone are frequencies: for example T-mobile originated phone has some frequencies different than ATT etc, so you would really need to check to see if they match your home towers. I'm not sure if US phones are region locked, my T-Mobile Note 3 has 18 network lock entries, not 64 and they don't look anything like the codes posted on this forum by other users. Mine look like this "network lock 310200, 310210, 310310 etc. so I don't even know what they mean. US phones are usually carrier locked, but could be easily unlocked especially if paid COD. But if your cousin works in phone repair shop, not only he should know about frequencies, carrier/region locks and technical differences between Samsung and Qualcom CPU, he could probably get you great price. I would talk to him more.

You should be able to find the N9005ZKEXSI which is the UAE version of the phone thats fully compatible with "My Number, My Identity" initiative. They are basically all the same except for basebands. I would stick to N9005 model due to developer support, snapdragon is better simply & exynos hasn't reached its potential & there is no word as of late on HMP to utilize all 8 cores.
Just remember, even though the N9005 is international there are still variants per country, which means the market they came from if you break it...is where it has to be repaired so buying a local N9005 model is the very best route to go which is the N9000ZKEXSG (Jordans version of Exynos) otherwise, you need to grab one from another closer market that does have the LTE model... aka UAE.
Get it from the country you spend the most time living in.

Some special registration thing from TRA called TRA:ID each device has one if you look in about device with stock rom or KEXSI csc. There will be two codes I am guessing you end up registering somewhere.
I cant really say as im using the kexsi 9005 in the states, its just something I saw while looking to see which country my note came from.

Question about Dual IMEI

Hey Community,
I have Samsung SM-G935F with one Sim IMEI , its possible make new IMEI (Dual Sim) ?
if thats work maybe can get SM-G935F -> SM-G935FD for Dual Sim , work nice if somebody cracked that :victory:
sorry no, imei is a hardware issue not software. currently you can not make a SM-G935F into a SM-G935FD, there a thread discussing the reasons why.

that is how your provider identifies the phone, it is burned into the eprom chip as which cannot be accessed by users. there have been cases where some roms have changed the imei to generic but that causes the provider not to recognize the phone.
Your imei is broadcast to the cell towers when you turn on the phone and when you make calls.
