[Q] Galaxy Tab SIM card

Can any one tell me why my TAB will not recogize my valid, working SIM card from my other phone? Perhaps some setting on the TAB has to be changed?
Thanks for any info.

dude
dude i dont know. i tried the same thing. i have tmobile usa and the Galaxy Tab, along with my HTC HD2. tried the swap, no dice. saw my phone number, but would not txt, call, or receive calls. no data either.

My TAB doesn't even recognize when that the SIM is plugged in .
It keeps saying: "Please insert a SIM card". "Emergecy Calls Only".

This is going to sound really dumb but try shoving the SIM card in further. With certain brands of SIM you can get a "click" without the SIM being correctly seated in the tab. The tab will reboot if you insert a sim properly while it is on.

Problem solved! I thought that it was unlocked, but it wasn't. Followed Rothammer advise on unlocking and that worked like a charm.

I have the same problem with my SIM not being recognized. I have an AT&T Tab; unlocked [verified network is unlocked]; flashed with Rotohammer's most recent JME-Full; Baseband is I9000UGJK3; IMEI is OK; and Mobile Network is HSDPA. Interestingly, the signal strenth shows full bars, but does not recognize SIM and does not allow me to enter the Mobile Networks [grayed out] to change anything. I've tried every fix from every thread I can read here. Any thoughts anyone to get this to use voice and data?

Flash the Bell i900 modem for at&t tabs.

problem with htc mytouch 4g and simcards

hello
my friend have used phone from t-mobile usa
and the phone can't read any sim except orange israel (don't know about t-mobile sim)
how can it be ?
and how it can be changed that the phone will read all the sims ?
now when i try to put any sim i got message "sim card not found"

This phone requires a certain type of SIM. Different SIMs have different shapes and sizes of contact area for the chip. Compare them and you'll see what I mean.

thanks for your answer
than there is anything to do to solve this ?
from 7 different carriers orange israel will be the only one will work on this phone?
btw . i now see other post you talked about the sim sizes...
in my case the sim size is identical
but i think the chip size is different
the one that work have a larger chip

look at the bottom of the sim and make sure the metal contacts are in the same place as the tmobile sim (look up a picture of tmobile sim on google if you need it) otherwise its possible that the phone is not sim unlocked

from what i see it's not on the same place as t-mobile sim
just orange israel sim is the same as t-mobile

Take a working SIM to the carrier you want it to work with and see if they will sell you a SIM that matches that type.

i don't think they have that type of sim
because they new carriers that sell just the new one
there is no service that can unlock it to work with all the sim cards types ?
or this is done deal ?

It not the carrier type that is the issue. This is the hardware on the mobo. If your SIM reads, but the phone is carrier restricted then it will tell you. Unless you are getting a message to that effect this is H.A.R.D.W.A.R.E.

as u said , i am not getting any requset to put any pin or puk or any unlock code...
but there is one carrier that the phone read his sim card (with the bigger chip on the sim card), but it's just 1 from 7 carriers , because the others have different types of sim cards.(the one with the smallest chip on the sim card)..
what about cellphone labs ? they can't replace the part that read the sim to one that can read all the types of the chips (that on the sim cards)
i am the first that stuck with that problem ?
i really don't want to buy another phone
i like that phone
there is no solution for this hardware problem ?
thanks

Cell phone labs? What? Dude it's part of the motherboard. It's engineered for and soldered to the motherboard. You just need the correct style of SIM card.
There are dual SIM adapters out there that MAY work. You could try that, but it will require cutting of the SIMs to make them fit under the battery.

i don't know why they bother to release phone that accept just one type of sim
that most of the phones can accept all the types

No sim card

I brought S4 just another day and when I insert sim card the phone says "No sim Card" but I inserted it already!
Its micro sim i'm buying another sim card today and see if it works,
Will customer service fix this if the problem is in the phone ? If yes then is it covered by warranty ?
Any help? maybe its software problem

And how exactly he should or anyone should know what's exactly your problem? Can be hardware or the simcard. This is up to you to find out.
First try a new simcard , and try to get one micro sim factory cut if you can, if still nothing means is hardware.

Did you put it in wrong?

GT I9505 doesn't detect LTE sim, works fine with 3g Sim
Hello all !
I own a 2.5 year old GT i9505 (LTE variant) which works completely fine with a 3g Sim but the "Sim Card not inserted" error appears as soon as a 4g Compatible Sim is inserted. Could this be a modem issue ?
I live in India (got the phone from Europe) and have been using 3g services without any hitch for the past 2 years. Vodafone recently launched 4G services here and my phone doesn't detect the new 4G Sim card .
My phone shows the LTE/WCDMA/GSM modes but doesn't detect the Sim card.
Tried with another Sim from the store that doesnt work either.
Details :
AP: I9505XXUHOJ2
CP: I9505XXUHOJ2
CSC: I9505EURHOJ1
All ideas and solutions are appreciated.

It's possible that there is something wrong with the phone's sim card reader. You could replace the reader for not a lot of money and it's easy to do yourself.

Maybe your phone is unable to detect LTE Networks from Vodafone India because from what I research, India uses TDD-LTE. You could Google-d LTE bands that used in India and compare it with your phone's supported LTE bands.

I considered that option but a 3g sim works perfectly. Do you still think it would help ?

I guess I am just lucky my phone supports both.

Still no luck !

I don't know that much about sim card technology. Have you tried the LTE sim card in a very old phone to see if the old phone detects the sim?

I did infact it works with every phone except this one.

Leads me to conclude it is the sim reader or motherboard if no LTE SIM cards work. Doesn't seem like software.

Xperia Z5 Dual Sim Card - doesn't support 2 sim cards of the same network

HI EVERYONE,
Hope you can help me or give an advice...
I got Xperia Z5 Dual Sim Card phone. I'm on UK network. If I use both sim slots with the same provider, one of the slots stops working immediately. Shows no signal bars whatsoever. As soon as I use two different sim cards from different providers, both work fine. I called my network provider, but they state it's a phones fault.
Has anyone experienced anything like that?

Can you buy new sim card? And try with the new one

Could it be your carrier doesn't have GSM coverage in your area?
I think 3 in the UK does not have GSM. When you are in 'dual standby' mode one of the SIM cards MUST be on GSM only mode, therefore if your carrier doesn't have GSM it will never connect. This is a funny limitation, but it's what allows for dual standby phones to be made relatively simple without having to have two radios for two carriers, which would make the phone a lot bigger and complicated.

I went to the actual store and swapped the sim cards, but nothing helped

I never thought of that... It's strange as I went to Vodafone store and they said they don't support dual sim card phones at all.
I am actually with network 3, so thought there shouldn't be issues like this. Another funny thing is, that if I swap the slots with the same network 3 sim cards, sometimes slot No1 and sometimes slot No2 isn't working. As soon as I put one Vodafone and the other network 3 sim cards, both slots work just fine

I used my Z5 Dual when I was in the UK and was having real problems getting the EE sim card to work on the data side, it seems that when I put in the EE card my phone restarts (annoying but standard) and it resets the data preference to 3G which meant that I had no coverage. As soon as I switched the data preference to LTE it was up and running full guns again.

Nexus 4 only work with at&t mexico, no other carrier

Hi, i recently buy an used nexus 4 in ebay, simply for nostalgia, so, i´m in Mexico, the nexus 4 that i had 3 year ago, was unlocked, so, i supose this too, when arrive, i connect to wifi immediately without any sim inside, the cellphone request for one upgrade, i accept, after that, i put my sim from Virgin Mobile and the nexus only showed " no simcard inside, only emergency calls.... y try with other carrier, weex mexico (virgin and weex work in Movistar, they are OMV) and the same all.... finally y put a sim from at&t mexico, nothing... with the sim (att) inside, i downgrade to android 4.4.4, when woke up, the nexus 4 with the same result, No simcard, so, the cellphone wasn´t detecting any simcard, after that, it request for the next upgrade, lollipop 5.0.1 that i accept, but in this chance, the nexus with the simcard from ATT showing signal¡¡¡¡¡ the cellphone was working at 100%, i made a couple calls, without problems.
But, i try with the other 2 simcards, and it doesnt detecting, simply show again No simcard, emergency only, so i switch back my Att sim and this is detecting without problems....
I install a rom named Pure Nexus, waiting for work, but the same, only with ATT simcard work, so i downgrade again to 4.4.4 but in this chance with other simcard differnt from AT&T, Virgin mobile.... but nothing, nexus 4 is not detecting any other simcard than at&t¡¡¡¡¡¡
What can i try? could be a nexus 4 locked only for one carrier or what? in google dont appear in blacklist, the imei is good nor corrupted... could be the sim holding?

try going back to stock using the nexus 4 toolkit,then root, and try one of the hybrid models LTE enabler or download the 107-3, if that doesnt work also, then it might be defective.

use this to go back to stock
http://www.wugfresh.com/nrt/
you will get android 5.1.1, you can also install custom recovery and root using it.
then if the sims doesnt work, change the modem using the LTE Enabler you can get it from the Play Store.
it has the modem until version 104-33, but im using another one the 107-33 that i got from
https://drive.google.com/open?id=0B77BTW0zStYCZmpPR0xTaWE5OUU
104 33 and 107 33 are hybrid modems, but you can also install stock modems,
the modem is the one that allows you to make calls and use the data channel in your phone
hope that makes sense, let me know how it goes. regards.

well, i flash EnableNexus4LTE.zip and LTEhybrid33-84 without good news, i have the same issue, only at&t mexico sim is detected and the others no, well, i´m now with 4G LTE but only working in at&t
i don´t know what other things trying in the nexus, seem like only prefer at&t sim and no one else.
Adding information, i have sims from cricket USA and t-mobile USA, i know is not supported in México, but it will be for try to get something like: Sim not activated... or invalid sim, but other different from my nightmare: NO sim, please insert....

SOLVE:
I´ll auto answer... after a lot off attempts, i found the problem is the sim reader, like i posted before, only working with at&t Mexico sim, so, I watch the thickness of this was little bit smaller than others, my "strategy" was try to imitate the fact that at&t sim is making contact gently on pins, i take a 3in1 simcard, and i put the nano sim in micro sim adapter (included in the sim) but not in all (i don know exactly the words in english), so by this waya the nano sim standing on a little bit from microsim adapter.
when i insert the sim by this way an my nexus, and turn on, the cellphone recognize inmediatly the sim, so i found the key of this problem, like i said, the problem here is the sim reader, because, a normal and good sim reader not need this tricks to get signal.......

i just sintall LTEhybrid33-84 and EnableNexus4LTE with TWRP custome recovery, but apparently without any 4G signal, in the menu mobile networks only i can choose 2G & 3G.... but the baseband does change.....
so, i use the trick hidden menu with *#*#4636#*#* and i choose LTE only, only with this my nexus 4 has 4G signal¡¡¡¡¡¡ but, if i come back to mobile networks, again only i can see 2g and 3g and the little 4G on top disappear.... so i need to come back again to hidden menu....
conclusion, mobile networks menu it will prohibited for me :silly:

you should be able to select "LTE/GSM Auto" that way the phone will switch to GSM when needed.
and the option is only visible under *#*#4636#*#* menu, also, we have to switch to LTE/GSM auto, if the phone is restarted. there is a way to make it persistent, but I haven't tried. i'm fine with it since i don't restart the phone too often.
hope this helps, regards.
