I visited my sister in Germany and she gave me a Vodafone branded Xoom2 UMTS (MZ616). I was able to flash it with ICS and everything works great.
I got a new sim card from ATT (I live in ghe US)and put it into the tablet. This is were my issues start.
I see no APNs. When I add an APN it disappears or I cannot save it.
I tried everything. Sometimes when I try to manually search for the network ATT pops up. When I select it, it will show bars for a short time or i may get a "sim not authorized for this network error.". When I add data roaming, it may shows the ATT APNs for a short time.
I also get an error when trying to add a simlock I get a "no sim card" error.
I am stumped. I searched the various forums and I get a lot of inconsistent info.
Is this issue related to the tablet being locked? Does that even matter? Is this some sort of region issue? Do I need to unlock the bootloader or should I use a different ROM?
I do not think the sim card is faulty.
Any help appreciated.
Sim Card Size????
So I compared the old Vodafone sim card with the 'new' AT&T sim card. The plastic outline of both cards seesm to be micro. However, the gold plated contacts on the new cards are definitely micro sim, but the old Vodafone card seems to be old school size (not sure what that size is called). If the size of the gold plated material matters, then this may be may issue. Like I said, above, when I first boot into the tablet with the new sim card I will have bars for a short time, but they disappear and the sim card does not seem to be recognized.
Can someone knowledgeable on sim card size matters as they pertain to the Xoom2 please weigh in and let me know if this is the issue?
I took a pic of the sim cards. From left to right: Old Vodafone sim, new AT&T sim, 2FF (mini sim card) for size comparison.
Please post all questions in the Q & A section. Thanks! Thread moved.

I wanted to test the unlock i did on my phone yesterday, so i put my brothers tmobile sim card in my phone, but all it did was show a sim card icon at the top of the status bar, and i didn't have signal. so i just figured the unlock didn't work.
Then when my brother put his sim card back in his phone, his wasn't working. apparently the sim was reformatted or something, and now he has to get a new sim. anyone heard of this before? also should i try another sim card, or will it just destroy that one too?

you forgot to select network operators in the wireless settings. in the wireless and network setting select mobile network then select network operators your phone will then scan available network operators and show you at&t or t-mobile after the scan. since you want t-mobile simply select it.

would that have made his sim card work again if my phone recognized the network? or was that just something weird that happened. I am new to the whole unlocking deal.
Thanks for the help, I am a little nervous to try it now, as i dont want to mess up his card again! :/
you should be fine. is your contact actually stored on your sim? ,maybe your brother's sim is empty but his contacts are stored in his phone. contacts stored in sim card are not easily get deleted than contacts stored in phone simply import you phone contacts to your sim to be safe.
my contacts are fine, but his phone actually would not work when he put his sim card back in his phone. it's just a regular dumbphone, but he didn't have signal or anything. Do you know what would cause that?
there must be an option somewhere in his phone to select the wireless network he has. what phone he is using? maybe a simple reboot on his phone with his sim card already in place would do.
yea maybe, i think he was going to go to tmobile this morning.. i guess i can't really call him to have him try though!
anyway i'll see if he will be brave enough to let me try again! thanks for the help!
I may understand sim cards wrong but from what I understand the sim does not announce to the carrier hey this is eric shins phone. It instead just broad casts a number the carrier sees the number and associates it with eric shins number. That's why you can buy a prepaid att phone call the company up, give them the sim number and they can connect that with your phone.
More then likely the sim was physically damaged

hmm.. that does make sense. I thought i had heard of other people just popping in other people's sim cards and it wasn't a problem, but i don't know.
Just kinda strange that it was working before , and after i tried it, his phone no longer worked. Maybe it was damaged when he took it out or put it in, but from my experience they are pretty sturdy pieces of plastic!
i'll have to see what he says when he gets it fixed.

hmnn... thats what I thought because the op post that somewhere in the process when putting back in the sim he see's it was reformatted. just like putting an sd card with my other phone that is not samsung it can't read/open files unless you format it that would surely delete the data in it. in his instance without a warning it automatically formatted the sim and deleted all the data in it which would make it useless. in his case the sim card before is associated with the network but somehow reformatted and the data in it was lost.
so he went to tmobile today and got a new sim card, and everything works again.
maybe it did get damaged in the process.. who knows now!
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.
Hey all,
I'm trying to use a foreign SIM card (a prepaid card from Taiwan Mobile), but my phone says "No SIM card in phone" on the lock screen. I'm sure my phone is rooted and I flashed Android Revolution HD 5.2.6, but the lock screen is still giving me the same message. Is this a problem with the SIM card, or my phone? I also had the same problem when I got the phone, when I upgraded with a dumbphone from AT&T to the Inspire 4G, and AT&T had to give me a new SIM card. Also, the contact size for the SIM card is smaller on my AT&T 4G SIM, so I don't know if that might be of any help. Thanks!
My first assumption would be that whatever language the card is written in, the phone isn't able to translate. But I don't even know if that's a real thing or not either. So this post was pretty much pointless in helping you understand your problem.
I'm sure someone smarter will be by soon with some insight.
*insert sig here*
Not all GSM phone services are 100% intercompatible. I don't have any idea how you would find out, but a good start might be to call a rep at Taiwan Mobile.
Wondering if anyone can help, im using team Eos European 3g rom zoom. now i tried 1 sim card and the 3g works perfectly but when i try my other sim, i enter the pin code on screen , it accepts it, then immediately says "Sim card removed, the mobile network will be unavailable until you restart...." .
The sim card definitely isnt broken because it works in my phone and 3g modem on my pc. I've tried restarting the xoom with Wifi off and no luck.
Thanks

how old is that "other" sim card? Reason I'm asking is that sim cards use different voltages and old cards tend to cause problems in modern devices.
Around here, providers usually swap sims for free if you say that you've got a problem with one, so I'd go for an exchange if your sim is older that maybe two years...

Its actually brand new, got it on the weekend. It works perfectly everywhere else. I think i'll go to the provider anyway today and see if i can try a sim swap.
This really is baffling me now. I went back to the providers store and tried a different one of their sim cards and it doesnt work either. I just cant understand why my xoom can read certain providers sim cards and not others? (Its definitely not network locked). Could it possibly be the type of sim card (as in a 32k vs 64k etc)?
Any help would be greatly appreciated
Hey guys. I just got a moto g today and I find this quite annoying, because when I turn it on before unlocking it it comes up with an error saying "Vodafone NZ, no sim card - no service". It's odd because of the fact that I am still able to use the phone in both using the internet and text / call. I've come to realize that the no sim card part is due to the fact that it's, perhaps, referring to the second sim card slot being un-used. But the no service part does not particularly make sense. Also when I unlock the phone it also has a red slash going through a sim card on the top left as well as the red slash going through a graph, referring to connection.
I got the phone today and when I got it I had to get a new sim card and load my current number on it at the vodafone store, the guy did it for me.
Any help will do. Thank you.
Yeah, it's referring to the other sim card, both sims are always displayed. When I had two sims in, they both showed the carriers. "Vodafone NZ" is one and "no sim card - no service" is the other.
Okay. So essentially what it is, is that the slash through both the other sim and connection is refferring to having both no sim and connection via the 2nd sim card? so I need to get a 2nd sim in order for it to go away?
Yes to both questions. If you get a second sim, it will look like the other one.
There are some mods to get rid of it, but I think it's a much of a muchness...
Fair enough. I can only presume it got there because the vodafone guy put the sim card in both slots, therefore activiating the 2nd one. Fair enough though. It's not doing anything just annoying my ocd ;D !
Thank you so much for your assistance.
You're welcome.
Mine has both, they're there by default. It's okay, it's a common complaint... XD
