Galaxy Nexus..some type of sim cards not detected....

Hi guys,
I have my new Galaxy Nexus unbranded, here in Costa Rica we have some carriers, the main one ICE (Green frog), and others like, claro, movistar, tuyo movil, the thing is the nexus does not recognize the main carrier sim card but if you try with tUYO sim card it works great.
I attached the picture of both sim cards.
I really appreciated any help or suggestions.

The one on the left looks like the normal one based on the chip position. The one on the right looks odd, may be a very old sim? Can't you exchange for a newer sim and try?

I'm having the same kind of issue, I've already unlocked the boot loader, rooted and reset everything on the phone and only one type of SIM card is read, I've tried 3 different SIMs and only one seems to work, none of my postpaid lines will work either, it seems that only that particular pattern will read on the Galaxy Nexus, has anyone else had this issue?

This is not an issue with the Gnex....it is with the sim cards.....there is a plenty of phones (even cheap ones) that don't read some sim cards witch have a specific scheme ......i have some experience with that.......
Plus....the Gnex with 4.0.1 doesn't read sim cards with a pin lock....it's a bug......

looks like the sim cards are not the same as the "main stream" or most common sim cards. i reccomend trying a sim card were the chip is like most others.

mines read my sim card on 4.0.1 and same with my wife 4.0.1, both pin locked.

Thanks for the replies, but the weird thing is, among the SIMs that don't work the one on the end of the photo I just posted is the same pattern as the one that works. So if I understand this correctly, unless my carrier uses the exact same SIM for postpaid lines as the prepaid one that works, I have no hope of using my unlimited Data plan with my GNex?
Does this also mean that even if the SIM will work on an HTC Flyer, iPad, iPhone & Huawei E5 Modem, and it doesn't work on the GNex, it's still the SIM card at fault? I'm really having a hard time wrapping my head around this.

Have you tried getting a fresh replacement sim from your carrier(s)? All those sims look pretty old to me.

Except for the cut Micro-SIM, all of those are brand new

Carrier has no alts? Over here they do, and tbh, I haven't seen sims in those designs (apart from the cut one) in quite a few years. They look like 2004~ sims (at least thats when they looked like that over here)

Our Telcos are terribly inconsistent with regards to their SIM cards, the newest one in the bunch is in between the cut SIM and the OK SIM, I just find it irritating that I can't use my Main SIM card with the GNex, for now I'm stuck with the prepaid one that's OK.

Note 2 takes a normal SIM card ot not?

I have made my Note 2 preorder in Expansys Pro, but now I remembered one important detail for me, can I use the Sim card from my Note 1 or do I have to order a new one because of the 4G or because of the size of the SIM card.
I read somewere that the Note 2 will have micro SIM card, but I also read that it will have a normal SIM card, that's why i'm confused.
Thanks

I sure hope for a normal size, there's enough space in the device.

microSIM guys. Regular miniSIMs are a dying breed. Most phones are moving to microSIM and even the newer nanoSIM (next iPhone.)

its microsim . http://www.youtube.com/watch?v=ealqvz196M0&feature=plcp , 2:20

Thanks. I Think its time To change my old SIM card.

Thanks Guys this good to know:good:

Durn... I'm in the same boat. Preordered from MobileCity with plans to use SIM from Note1. I guess now I need to find a cheap phone with a microsim, since ATT doesnt do well with phones qith unrecognized imeis. Bummer.

You realize they make SIM cutters, right? As long as your contact patch comes out unscathed when you cut it, it should be good to go.

Att should allow you to sim swap your note sim for a microsim. It sucks that we can't then go back and forth between phones though. I guess we can use adapters, although I recall the note doesn't play nice enough with some of them.

You can cut the sim into a micro-sim.

Not change the SIM. Make this:
http://tecnologia.uol.com.br/mundo-...ra-o-ipad-3g-pode-inutilizar-dispositivo.jhtm
I tried w/ a old SIM and work. I cutted it w/ a scissors.

I cut loads of Sim's at work, haven't had one fail from it yet.
Just use one of these:

I just phoned my Operator (TMN Portugal) and they say I can order from them one microsim to replace my old one for free.
I don't have to pay nothing for the micro SIM, so I think I will order one for me.

[Q] [SOLVED] Possibly damaged SIM slot?

In my Galaxy S4 mini's whole lifetime only twice has a micro sim been inserted. The first time I inserted a SIM card inside there, it worked immediatelly without any problems as soon as I powered on the phone (the sim card was cut from a normal one manually by me).
Then I left the phone unused without a SIM inside it for about 2 weeks and just today I tried to put back the same SIM card and the phone always displays "No SIM". Tried taking it on and off like a thousand times but still no effect.
The card is working on another phone but with an adapter as I don't have another phone that uses only Micro-SIM so I can't really test.
Any ideas?
EDIT:
Here is an image of what the SIM looks like and how it is inserted. I would greatly appreciate if someone from here checks the exact form and placement of theirs and compare it to this image:

Are you saying it could be possible that I just cut the SIM card badly? I'm planning on heading to the store and asking for an original Micro-SIM from my carrier but I'm afraid that might not be the solution and it would be a waste of money.

Yes, I would try it

you can buy another if you think is broken from this link

Problem is, all of my friends use normal SIM.
I just watched a video how a person types a hidden code into the dialer which takes him to an advanced service mode and from there after choosing some options, the "No SIM" error immediatelly disappears even without the need of a reboot. I believe he reset the modem or something.
I thought it was a firmware related issue but that might not be the case also as I flashed two different firmwares (both for my region) with Odin and it's still the same.

Is it normal that the center pin is a bit down than the left and right one?

There was previously a user who broke one of the sim card reader clips. It could be possible?

Yep it turned out that was the case, no firmware issues or anything of the sort. Luckaly mine wasn't actually broken but it just somehow went into the bottom too much. I used a small needle and tweaked it a bit hoping to push it back up and achieved it without breaking it.
Now it reads my cut Micro SIM just fine. :victory:

Scary that those pins can bend so easily.

I've just had the same problem on my mom's S4 mini: central pin lower than the other two. Bending it up a bit solved the problem.
In fact on other S4 minis the three pins are level.

Moto Z Play XT 1635-02

Hi just wondering if this is correct
I bought my Z play from handtec.co.uk
Model XT-1635-02 I'm in the UK and that particular model according to a site says it's the Brazilian country or region where sold , or is it just the generic unlocked version , maybe a stupid question but what the hell" just i wondered if it would effect my my carrier who is Life Mobile who are part of and use the EE network as by default the apn setting always defaults to something different other than the ee apn my network states to be the correct apn , although 3G and 4G work I do notice alot of signal loss/drop outs and if I have H+ at the time it comes back up G and I have to restart device to get H+ back every time ,, very annoying
Thoughts any one ? [emoji51] [emoji106]

My US moto Z play is also XT1635-02, purchased on amazon. Maybe you can remove the other apn settings?

I have amended apn to supposedly right one will see to day of helps

Don't think anyone has taken the chance of bricking by flashing dual SIM firmware on a device that shipped with single SIM. I ain't trying it, even though dual SIM would be very convenient in my current circumstances.

I removed the 2nd sim cover, set build.prop as per the Moto x play thread. Net work is recognized but no signals

Pixel 3 XL - Sim Not Detected Issue

Hello Everyone,
I just purchase used pixel 3 xl, it was advertise as not working sim, Phone is in perfect condition with box and all accessories,
But it doesn't recognise any sim, I already reinstalled android 12 and even downgraded it to 11 but still no sim detected,
I can see that imei is exacly the same as on sim tray and box, wifi and everything else is working fine, charging port as well, but still is not detecting any sim,
Can someone help me or at least suggest what should I check, at this point I have no clue how to troubleshoot this case,
I don't want open the phone and replace sim slot yet, because phone look like new,
Is any chance that this phone might have region lock or was stolen and that's why sims are not working ?
Previous owner was using ufone sim card, and I tried EE and Three sim
I would really appreciate if anyone have any suggestion what to do next before I will start replacing parts,
Here is screenshot from my phone if it's help
