Galaxy Mega SIM Problem - General Questions and Answers

I have a sgh-i527m (Bell) which got unlocked. I tried a few custom roms but went back to this stock rom since I wanted full functionability.
Periodically, I would get the "no sim card" error. A simple reboot or re-insertion of the sim card usually fixed this issue but earlier today, It just clunked randomly and no matter what I tried, I could not get my sim to work (Fido). I even went to Fido and got a new SIM, since my sim was so old it wasn't even the LTE sim. And still no luck.
I even tried using the scotch tape Nexus fix, still nothing.
I tried re-flashing stock rom, no luck. Going to try a nandroid backup.
Also, my friend's SIM works fine, which is Rogers but my Fido sim won't work yet my Sim works fine in his phone (unlocked i9500). Ironic, because Fido uses the Rogers network..it makes no sense.
Somebody shed some light please?

Unlocked Tilt and No Service on T-Mobile Sim

I have just unlocked my tilt with Kaiser SimUnlocker. I put my T-Mobile sim card but no connection. Always searching... I put my friends Cingular sim card (old at&t) and still no connection. So I thought my phone was broken so I took it to local AT&T store and one of the rep says 'maybe it's the sim card'. And he grabs one of his new AT&T sim card and voila! connected. Have anyone had that problem? What can I do to fix this? My T-Mobile sim card is says 38.01e on the card next to my sim serial number. Is it my sim card? Do I have to get a new sim card? I've just got this sim card about 2 months ago. Any suggestion?
I assume you reflashed an appropriate radio after unlocking?
I would try flashing a new radio anyway to see if that sorts your problem.
I've tried severa different radio roms with no luck. Right now I've reflashed back to US At&T rom. I still no clue why my T-Mobile sim will not connect to the network...
On AT&T, the tilt requires the newer AT&T 3G cards - thus probably why the Cingular card didn't work. Are you sure the SIM unlock process worked for you? If your T-mobile SIM is that new, I can't imagine you needing a new T-Mobile SIM. The T-Mobile SIM has worked in another phone?

That's strange b/c my Cingular card works on my tilt.
I unlocked my AT&T Tilt and then put in my (almost 1 year old) t-mobile sim card and it worked immediately without any problems. I used the original radio as directed in the unlocking tutorial. So it sounds like maybe you should do the unlocking procedure again. ?
Hope this helps,
stacy
did you even try putting ur sim into another phone and see if it works? just making sure u covered everything here
Maybe you are locked into 3G
Go under Phone/Options/Band and make sure the top is either set to Auto or GSM
Thanks for all the replys...
I have tried just about everything...
I know it's unlock b/c it does not ask for unlock code no more. I have hp hw6945 that is also unlocked and works perfect in there. It connects almost instantly so I know my sim card works too. Also tried changing band setting to Auto and 900/1800 and everything and no luck... Going crazy and frustrated... about to just sell it to some at&t user and buy a new one, try again.
Just to let you xda'ers know that when I tried to unlock it for the first time I tried with spl-1.56 on it as a factory (dummy me) then tried SuperCid unlock which changed to spl-1.0 then proceded with rest of the unlock. Maybe that messed something up?
I've had that issue but my sim card with t-mobile was 4 years old. Had to purchase a new sim card and everything worked fine after that. With my old sim card, the tilt wouldn't even recognize the card.
Anybody want to donate an old T-Mobile SIM to me
buddy had same issue just happen.. he had to go to tmobile and show them the sim wasnt working they gave him a new @ no charge
I had a old cingular card that came with my Razr and it worked fine in my 8525 Hermes, but it said no service in my 8925 tilt. I would try a new t-mobile card.

G2X won't recognize SIM card

Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.

No SIM Card

Hey everyone, I am a Galaxy Nexus user but my brother got an old Roger's S2 LTE that he wants to put on a non-Rogers network (same one I am on with my GNex). However we are having a weird issue where if we insert the original (deactivated) SIM that came with the phone it detects it. But if we put in either mine or his own it just always says "No SIM Card". I even have a pay as you go AT&T SIM that wont work in it either. So far I have flashed CyanogenMod and tried the UCLF6 radio as well as the Rogers ICS Radio UXLF3 from this thread http://forum.xda-developers.com/showthread.php?t=1754473
I should note that when my brother originally inserted his SIM he got the unlock screen and paid to unlock it through cellunlocker.net and it was recognizing his SIM at that point. Since then however we have had no luck. He even replaced the SIM card board with a new one.
Any ideas? I am leaning towards hardware issue but its odd that it still reads the original inserted SIM
did you try to go back to stock firmware and see what happened
Yep. I'm pretty sure its hardware. I got it to read again but still no signal. I have it reading my AT&T card now but again still no signal.
In fact even without a SIM card in if I search for Network Operators nothing comes up. If I do the same on my GNex I get a listing so its looking like this phone is no good
EDIT: Just realized who responded. Your threads were VERY helpful for me! Thanks so much... I'm still not convinced the phone is toast... I have a friend with a GNex on Rogers (I'm on MTS) so I will see if I can borrow his SIM and see what happens

agree, not the phone, the only way to make sure of anything is to restore to stock and do all the testing from that point on
edit: dah, its the radio, what freq is the new sim card on that wont work, is it the same as T-Mobile
edit: maybe not radio, think its like rogers, could be network settings
Actually both MTS and Rogers use the same towers so the phone should be set properly.
I've got it reading my MTS SIM now but cant pick up any networks. Its set to LTE/HSPA/GSM (Auto) and MTS is HSPA.
Is there anything that could be done to the IMEI of the phone to sort of "blacklist" it from working on any network?
Here is where I have tested from so far:
Stock before I did anything to the phone (Stock rogers GB)
CM9 Nightly
Stock Rogers ICS
SkyICS
I have also tried both the lastest AT&T Radio as well as the latest Rogers Radio. With my GNex both myself and my friend on Rogers use the same Radio (UGLC1).
At this point it seems either the radios arent working at all or the phone is blocked somehow
EDIT: Info on the MTS network... Found on the FAQ on their site:
Any unlocked devices (i.e. devices that are not tied to a specific carrier) will work with MTS SIM cards (on the MTS 4G network). However, carriers such as Rogers, Bell and Telus lock their devices to work with only their SIM cards and these devices will not work with a MTS SIM card. Similarly, MTS intends to lock our devices to our SIM cards. Therefore, our devices will not be usable on another carrier's network.
Please note that any unlocked device must support 4G North American Frequencies (850Mhz), older GSM devices will not function on our new 4G network. You can find out if your device is 4G compliant by reviewing the phone's settings.

UGLC1 never seen that radio for the skyrocket
edit: oh, for the gnex
did you try the *#2263# menu
Yes when I try that menu (*#2263#) it doesnt do anything. I can do *#*#4636#*#* when on CM9 and it works but on stock and SkyICS it just FCs when I select "Phone Information"...
I am going back to Rogers Stock ICS right now. Gotta head off to my engagement party but will likely be back at it tomorrow
shouldn't forceclose, redl and try reflashing x2 the rogers radio, wipe/format x3 in cwm b4 going back to stock ics
Will do first thing tomorrow (or tonight if I'm still in any shape to do so )
If anyone reading this thread has a stock Rogers phone can you turn it off, take out your SIM and then boot it up without a SIM in it and then do a Network Search and see if anything comes up? On my GNex I get networks but on the S2 LTE I dont. In fact I have never seen any signal from any network on this phone yet with an MTS, AT&T and an old Rogers SIM
EDIT: Actually you will probably have to be on CM9. With stock you cant get to the Network Operator section without a SIM card inserted but in CM9 you can

Ok I had enough time to do as you suggested above. Wiped like crazy then went back to stock using the ODIN method and the firmware from sammobile.
Actually I figured it out... it only FCs when I have the AT&T SIM card in and I think thats because AT&T is RAT Locked? If I have no SIM in I can get to all the menus.
k, try to set the freq(play around with it) in that menu w/out sim, then shutdown and install sim b4 restarting, left haptic to click "end" is saving
Got home and went right to work. Almost positive the problem is the radio not working now. I managed to get both SIMs reading without issue but neither will get signal of any sort (even straight after stock reflash). Gonna call it for now until I get a hold of my buddys Rogers SIM.
Thanks so much for all the help, I really appreciate it!

A problem with sim card after official at&t 4.0.4 upgrade

I bought an unlocked skyrocket yesterday and then tried to reflash the stock 4.0.4 rom on it. After that, the phone seems to be unable to recognize the sim card, and the carrier's label is gone sometimes. Now I can still make calls and send sms sometimes, but i can't most of the time. Can anyone tell me if it's the problem with the phone unlocking process or something involved with the rom I'd just upgrade?
what network you're on and SIM ? try replacing the SIM first of possible
i'm using a sim from a Vietnamese mobile network. I bought this phone for my mom, and last night it was unable to regconize her sim. I also try it on my wife's and my dad's, and they were all unrecognized. I turned it off and retry this morning, and it 's working like nothing happened before =.=. I just dont know if it's gonna be in that situation again

Stock JB Update Hosed up my radios?

I was blissfully working just fine on my MZ602 Xoom. I would pop the Micro SIM card out of my phone and into an adapter whenever I wanted to use the Xoom. It worked flawlessly.... that is, until I updated to JellyBean. Now the Xoom will not even SEE a SIM card.
I went to Verizon store today and the guy was about as helpful as diving gear in the sahara. He said you should not be able to pop a phone SIM into a tablet and it works... well that's BS cause I've been doing it for almost 2 years. "Well, then the update must have fixed a bug that allowed you to do that"... no duh sherlock... pop a SIM in from your repository and make sure the things even works still and I'll buy a tablet package. Well, he did and it did the same thing, no connection. "Not under warranty so, sorry man". Thanks for nothing, no I don't want a new tablet!
[/Rant]
I have since flashed the ICS radios and have the same issue. I have tried stock, non stock, rooted, non-rooted, Honeycomb with ICS radios, JellyBean radios.... nothign works, it no longer sees a SIM.
Previously when I popped in a SIM it would take a minute or two and then see signal, sometimes requiring a reboot, now it doesn't even recognize that a SIM was inserted. Before even if it wasn't picking up signal and I removed the SIM it would give a warning "SIM removed, reboot?" or somethign like that.
Currently running CM10.1 with the IMM76I radios. Works on WiFi but will not see any SIM card... am I hosed? Any help?!
Anyone?
How about this... Does anyone here still use their 4G Xoom on the Verizon network?
I plan to steal sim card from my wife ipad and try if I can find my sim adaptor. Will let you know.
I can tell you that my xoom no longer shows 4g network but always did before the update even though the sim card wasn't activated.

Did you use Rogue recovery to flash the radios? TWRP and regular CWM don't flash the radios properly.

Yes, used Rogue to manually flash ICS radios to no avail.
Previous load was 100% stock, unrooted on OEM bootloader and using stock recovery so the JB updated radios original flash was done properly.
I tried the Sim card from wife's iPad and it seemed to work OK. Although it seemed to connect a lot more to the 3g network than LTE and I have very song LTE signal. Radio doesn't seem quite as good as Previous.
