HTC windows phone 8X automatically reboots - Windows Phone 8 Q&A, Help & Troubleshooting

Hi all.
One of my friend has this device and it works perfect when there is no simcard in the phone.
But when he insert the simcard it reboots automatically after a few seconds. The simcard is MCI (Iranian operator). How can we fix it?
He tried factory data reset and updated to WP 8.1

did you (or friend) try other SIM card?
try other SIM card or ask operator to replace SIM card
also check connectors in SIM tray not bend or broken

He tried some different SIMs.
There is no problem with that and every thing seems well.

umm your service is disconnected?????
no,its not reading the card slot at all
This may be a stupid question- is the SIM card in the proper way? When did this start? What changed? Did you drop the phone?

When I first bought my Tilt used, I had the same problem. I had to stick a tiny part of a post-it to the back of my SIM and shove it in there. It's like my SIM wasn't thick enough.
The best way - to try with another SIM (maybe your friends have a mobile-phone )
Sometimes the old SIMs don't want to work with modern devices....
well heres my 2 cents as i just fixed it, my issue at first i thought it was the sim slot (replaced...) then found out the ribbon was damaged a crack occured, after another week of waiting for a package (today) i replaced it and now its running fine
Same here
My Sim was no longer available.
Kaiser had "sim card is missing", but the sim was in there.
I disassebled it and found that the main flex cable was damaged.
Now I'm waiting for replacement.
So, When the phone shows up "sim missing" it's an flex cable matter not the sim card flex or the sim card unit.
same problem here
I'm having the same problem here. thought that it was the flex cable of the sim, but when I disassambled the Kaiser I found out that the main cable was slightly scrached from a corner, and the sim's cable was there pluged well... I'm trying to fix it..gonna post the result for "sim card failure"...

X8 SIM-Card Problem

Hi Everyone,
I have one big problem, when I insert my PlusGSM sim-card my X8 don't recognise it, but when I insert PLAY or T-Mobile sim they both are recognised and connecting to network. PlusGSM sim is working when I insert it to my SE C902, how can it be?
I will add, card was working hour ago, but stopped working after my X8 drop and battery fall out from phone -_-
I'm using nAa-kernel v06b, and MiniCM7-2.1.5.
Please for fast response, because I haven't access to my contacts
ouch! maybe u burn your sim card

As a temporary solution, you should insert your SIM in another phone to backup your contacts, at least to know if your sim is still works.
Edit: Oh, this's a old thread!
@bogysha
probably no, because it works on other phone.
Just verify if all the "Sim connecting pins" are okay and there isn't any damaged. Because every sim has the Chip in different positions (for me it is) and some doesn't fill all the pins, i think.

not that old xD

Invalid Sim error on T-Mobile HD7 with Tmobile Sim card

Hey guys
I have a tmobile hd 7 here
it had an atnt sim card, and worked, the phone was unlocked
as soon as i put an active tmobile card it gave the invalid sim error.
So i researched and decided to replace the sim tray.
Got the new sim tray over a month later and the problem didn't go away.
Did a factory reset, still nothing.
This is a tmobile phone, so any idea why this is happening?

Maybe it's your sim card problem.

That was the first thing I tried. I wouldn't have ordered a new SIM tray without testing that first...

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...

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] Dual sim issues

I have one sim that I wish to use for phones / text messages, and one that I wish to use for mobile data.
If I put either sim in on its own, it works fine.
If I put both in together, and set them so they are both on, the one that I wish to use for phone calls and texts does not register on its network (which is Three in the UK)
I am not sure what to do. Can the phone company have set it so it doesn't work in a dual sim setting?
Or have I just failed to understand what dual sim is?
Any help much appreciated!

Try interchanging the SIM, I mean just enter the right one on the left and the left one on the right. What you are saying shouldn't happen.
If possible try another 2 SIM to see if the problem is with the SIM or the phone.

OK thanks. I have tried it with another 2 sims and it works fine. So that means it's a faulty sim?
Is it possible the network won't allow dual sim, or should I just request a replacement?
Thanks

Before requesting a replacement just ask the network operator of that particular SIM that if they disallow Dual-SIM or not. If they don't allow using their SIM on a dula-sim mobile asking for a replacement would be pointless.
I am using 3 (UK) and Vodafone, no issues, so likely the sim
