Optimus 4X HD not recognising my sim card (three)

I have just bought an LG P880 and to my horror found that it does not work with my sim card.
Here are the details:
Three Sim card (GA6047) monthly contract
LG P880 unlocked
I have tried the following sim cards and they do work
O2
Orange
I have tried a factory reset and a hard reset with the Three sim card in and out, each time it fails to detect it.
I have tried the Three sim card in the following phones and it does work
HTC 7Pro
Nokia N900
Samsung Galaxy Europa (The phone it came with)
While waiting for Three customer services I tried the Three sim card out of my mobile broadband GA6029 and was shocked to find that it did work.
So here i am with two three sims, one works with the phone, the other doesnt not.
All three said was to go to a shop so they can see it for themselves.
Do any of you have any ideas?

3G is activated? :silly:
Get a new SIM-card ... But it's best if you go to a three store and try one of their sim cards first. Pretty sure it will work. Maybe the sim card batch you got is faulty somehow and just not recognized by the phone. Exchanging the simcard shouldn't cost you anything if there's a technical problem.

Strange. My three sim works. It's a micro sim in an adapter. Maybe there is an alignment problem?

With android I don't know...
With the old K990 I just had to flash with an open firmware.

I have full size three sim works fine, but make sure data is enabled or you won't get a signal...
Sent from my LG-P880 using xda app-developers app

Ok, so an update.
I went to the three store yesterday. They let me try one of their demo sims and that worked. So they gave me a new sim. But once the sim activated, it yet again didnt work. Same as before though. The sim works in several other phones.
Does anyone know about different sim types?
The sim is a normal mini sim. But i am guessing that their are diferent sims for different phones?

Try microSIM from three. Maybe it helps.

I had the same problem with italian sim. I discovered that pulling the sim 1mm over the battery solve the problem. Maybe the contacts of the reader and the ones of the sim are not at the same distance when the sim is full inside the reader.
Hope will help

i am not sure its FULL size, since that includes the sim tray which in early 90s and forward was a complete card with simchip you could push out
the regulars or todays sim are mini-sim cards.see more here

[Q] Voice: Out of service / Data: In service HELP!

I have lurked so much around XDA and still I have no solution
I own a Moto X XT1053 on Movistar (Mexico)
Everything was working fine until I got my SIM card replaced. Now Voice and SMS don't seem to function but Data from my carrier works fine.
When I try to dial I get a "Mobile network not available"
I have done "fastboot oem config carrier (all possible options) No luck.
I have switched from 4G to Edge since that seems to be the solution for many but that didn't work for me.
Yes I have searched for networks and selected "Choose Automatically" No luck.
I have flashed back to stock firmware using T-Mobile's firmware (which has always been my solution and everything worked flawlessly) but now that doesn't work. I've actually not a fan of custom roms I only do stock and xposed the [email protected]#$! out of it but even a clean stock doesn't seem to fix it.
I even went to Movistar and they believe its my phone since they tested my sim on another phone and voice worked on theirs.
Any thoughts on what could be the solution? Please Help!

Check the APNs?

I think your first statement supersedes your latter statement and everything in between. Just because your new SIM worked properly in another phone doesn't mean it's guaranteed to work in your moto x. Maybe for some reason your moto x is reading the sim as a data only Sim, or maybe it's registering on the network as a data only Sim.
did you cut the Sim to nano or did it come as nano?
Did you try a different SIM in your Moto X?

They did try another Sim on my phone and same, no good. Voice seemed to work on other phones. I personally believe my phone was blacklisted. When I went to get my Sim changed I forgot to mention the account was under my moms name. Now my new Sim is under my name but with the number of another owner (my mom). Which could explain why I get no voice or SMS but data works fine. I am actually on my way to customer service right now.

Well just returned from customer service. No good. Its the phone itself. :/

Have you solved the problem? I'm using Samsung Galaxy S5 and has similar problem... After couple of times of change rom the problem occur... I'm not genius and I have struggle with this problem for more than 2 weeks... See whether we can work this out...
My situation is:
1. Voice: out of service, data: inservice;
2. IMEI: seems normal
3. I tried two SIM card with different ISP, neither work;
4. I also try that two SIM card on my iphone4, both work well.
5. Since my phone is G900F HK version, and I'm currently in UK, so I tried latest UK stock firmware and latest HK stock firmware. Same...
I had do some searching and said that there are few reason that might lead to this problem:
1. IMEI error. Flash rom may damage your partition, if your IMEI is 0046*** or 0000*** something then this is the case;
2. Baseband related. Just flash some wired rom that no capable with your local bands?
3. still looking...
Good luck then...

Same thing
Did you ever solve this? I am having the same problem on my Moto x Pure 2015.

Can't imagine it not working, if there is two sim slots in the little drawer, I would assume it'd work....
Maybe it is some sort of software error. Have you tried a factory reset and see if it works after that?
Does vodafone in any way make any changes to the stock firmware (apart for maybe adding some customized Vodafone bloatware...)?

My money is on the firmware not supporting Dual Sim. Most carriers hate the idea of Dual Sim as its in there interest to prevent you using anyone else's sim apart from the sim they sold you with the phone. :crying:

Mi 9 - Android Q Mobile Network isn't available

Hi,
I just bought a Mi 9 for my gf as Birthday gift and have a big problem with it.
We use her Simcard from her further phone, which works there without issues, but the Mi 9 just let her use Data on the simcard (internet). No calls or texts in-/ outbound are possible. It always shows that no mobile network is available.
I already readded all APNs (Internet, LTE, GPRS) and tried a couple different network settings (*#*#4636#*#*). I'm not sure why this issue appears and searched allover the internet. Seems like noone else have this problem.
Version is 11.0.2.0(QFAMIXM) with locked bootloader. Could it be that seller flashed something wrong, modem type or whatever? Carrier lock wouldn't let us use the actual sim right? My own sim as well just work with data so it need to be an issue with the phone.
Thanks in advance
Chris

Noone have any idea what the issue could be?

This seems like an operator related issue and probably has nothing to do with the Mi9. Try operator related forums for more help. The only thing that comes to mind is to get a new sim from the operator.

Question:
Does mi9 recognize the SIM Card? Does mi9 ASK for your SIM Card PIN? Or does mi9 say 'no SIM Card installed'?

Hi,
Sim is recognized and contacts shown. Sim pin is deactivated so the Phone don't ask.
Mobile Network is shown and active and data/ internet works. Its just the GPRS funtions (Text, Calls) which don't work. When I try to call I get the "Mobile Network isn't available" message and texts don't sent.
Thanks

The Sim works fine in another phone and my sim which works as well, shows the same errors in the Mi 9. So it must be an phone issue.

What operator do you use? What operators are the respective cards you have tried in the Mi9? Did you buy the phone from a private person and not new in a sealed package? In this case contact the seller.

Do you have 2 simcards installed?
You also might try to reset the modems, howto you can find when searching the forum

Just 1 sim installed. 2nd slot shows the same issues. Will check the forum for modem reset thanks.

Hi,
Weirdly the phone seem to have a Carrier Lock. My gf uses SMART Prepaid here on the Philippines and as said just mobile data was working. Yesterday she switched the SIM for testing to Globe and with this SIM everything works. 4G is available and calls/ texts work as they should.
I'm still confused about this. If the Phone would be carrier locked, should another Carrier SIM not be functional at all? I don't get why Data connections are working then.
For now the solution is to get another SIM. Probably let it unlock in a store.
Regards
Chris

Question Help me fix it

Hello guys. I bought a s21 ultra 9980 512gb.
However, i cant use it with sim card as its not detecting the network. I dont get it what could be the problem. I cant even untick the automatic network search as i get error.
Will post you guys here some photos maybe you can help me out. I dont think is locked because i dont get any message when i insert sim to enter the unlock code. What could be the problem?
Please help. Thx

Are you sure its an active sim card?

Yes. I have the card in an iphone as its my current sim..

Is the Samsung running official FW?

Yes… original .

do you still have the imei number present in the settings and if you type *#06# ?

Might be sim locked by the carrier, you could theoretically still use the esim I believe if it isn't giving you an option to enter an unlock code.

Yes.. both imei show up.
How can i check for sure its sim locked?
Also, when i insert any sim, for one second the “no signal sign” near the battery goes away then comes back instant.. and it doesnt ask for any pin…
Thanks for your inputs

I have read about this issue before as well. Is this a "dual sim" model? Try the other slot if it is, and also try leaving the sim in and rebooting. You could also try "reset network settings" under settings. I'll have a look to see if I can find the thread where people said they had a fix.

is it yours from brand new? and have you checked to see if it black listed? also, there seems to be an issue with some Samsung where they are forced into airplane mode the only way you see this is the notification panel the airplane model toggle is half-lit blue I could be something to do with that. Failing that it could also be if you have dropped the device the ribbon may have come loose as this is a common issue with Samsung a range and that's all I'm seeming to fix lately

Hello. No, didnt buy new. I got it used.Yes its dual sim model. It doesnt appear as blacklisted.
Its not in airplane mode for sure. Also i did factory reset and also wrote all stock firmware ap cm bl csc from samfirmware..but its the same as before.
Also, esim doesnt show up under the sim card manager.

try *#2263#* to change bands, or *#0011#

Maybe also try to put the sim in the other slot, and see what happens. If all the same, try someone elses SIM card for a minute to see. Maybe your sim has become slightly damaged but your iphone still manages to read it, while for some reason the s21 is not managing.

Just tried the sim in my sisters s20 and works. Also tried her sim into this new phone and same . Even if i put in sim1 or sim2.

Found this online:
"In Settings go to network mode and set this to 3G only. Then restart your phone. This works in my case."

Thanks for your sugestion. But its the same…

I had the same issue on single sim korean unit...but factory reset resolved the issue. Actually i used to disable carrier apps which was causing this issue.
