Have you started getting a SIM card not detected, No SIM, No SIM Card in Phone, SIM not found, please insert SIM card or any SIM error messages on your HTC One X? This issue is not good; if your phone isn’t reading your SIM card then your phone isn’t going to have service! And if you have no service then what’s the point of having a mobile phone? Luckily there are some things that can be done to get your device working correctly again.
"SIM card not detected – Unable to detect your SIM card. Please make sure that your SIM card is properly inserted. OK"
is usually due to a bad SIM card or damaged SIM card tray, this issue on the HTC One X however seems to be a overly common issue due to a faulty SIM card set-up as a result of poor design of the unit.
Let’s cross our fingers and hope this isn’t the case with your phone. There are some tricks we can do to get your SIM to read correctly if your phone falls into this category but let’s go over some other tips to try first.
If you can, then try inserting your SIM card into another phone to see if it’s working correctly. If it works fine in another phone then it’s not a problem with the SIM being defective. Go ahead and plug it back into the One X.
If it doesn’t work in another phone then your SIM card is bad and needs to be replaced. Go down to an authorized retailer or call your service provider for a replacement SIM. Don’t let them charge you for it.
Let’s hope it’s just a glitch or software bug that’s causing this issue. If it is, then a simple backup and reset will fix the phone. And lucky for us this phone backs up a lot of its information automatically so a backup is a breeze and a resets even smoother.
Gmail - Your contacts should already be saved online through your Gmail account. To check, go into your Settings > Accounts (or Accounts and Sync) > check your Gmail on that page (write it down if you won’t remember it, you will need it later) > Click your Gmail account > make sure that Sync Contacts shows the days date on it. If it shows the days date then your contacts are saved to your Gmail account online and when you log back onto your Gmail account once you reset the phone your contacts should automatically pull back. If it doesn’t show the days date then you need to click on the Sync now button (note: connecting your One X to a Wi-Fi should make the sync go faster if it seems to be slow or doesn’t want to sync)
Phone Storage & SIM (if possible) – your One X phone doesn’t have a slot for a memory card (which stinks) but it does have a separate storage system built in that will be safe from a reset. And if your phone is currently reading your SIM then you can back up your contacts to your SIM as well. Go into your Contacts > Menu (three dots upper right of screen) > Manage Contacts > Import/Export contacts > Export to phone storage (I also recommend that after you do the phone storage option you do the Export to SIM card as well, if your phone will allow you to).
Backup any text (SMS) or multi-media (MMS) messages that are saved on your phone. Messages are tuff to backup and if you HAVE to save anything I would write it down, or you can try to save your messages to the phones storage... but I don’t know if you can use the SMS Backup and Restore application to save your messages to your storage but you might be able to use it to send a copy to your email.
If anyone has called you recently and you need to write down their number you will want to do so. A reset is going to clear the devices call log.
Pictures and Music
Don’t worry about your media files. They are stored to the alternate storage. As long as you don’t specifically tell the phone to “Erase all data” when doing the factory data reset then you won’t lose any of your pictures or videos.

Factory Data Reset
Your phones backed up and now you should do a reset. This will set the phone back to its default and if there is a bug, glitch, virus etc. then this reset should fix the issue.
Settings > Storage > Factory data reset (Note: on this page it’s very important that you make sure the “Erase all data – Erase music, pictures, and all data on the storage” is NOT selected. If you want to erase your pictures and media then go ahead and select it. When it’s selected it will have a green checkmark in it) > Reset phone > Erase Everything > the phone will power off and power back on.

When it powers back on then re-setup the phone, log into your Gmail account again, and the reset will be completed and hopefully it was a software issue and you will now be good to go. Note: if you get a screen during the setup asking you to go to a computer to setup the phone then tap the back button until you can’t go back any further and then tap cancel. Doing this will allow you to setup the phone through the phone and you won’t have to use a computer.
This is what was mentioned before in the beginning of the article. The HTC One X design has its SIM card in a tray and then requires you to slide that tray into the top of the phone. This tray isn’t always as snug as it should be and the SIM doesn’t connect to the phone correctly. Here is a good example of what I mean.
If this is the pickle that you’re in then try adding some layers of tape to the back of your SIM card to create a tighter fit. Make sure to add the tape to the back-side of the SIM, the side that faces the back of the phone, the SIM is just loose and not resting snug like it needs to be. The tape will push the connection together and the SIM will no longer disconnect from the phone and NO MORE SIM ERROR.
If you do all these tips and your HTC One X is still showing SIM errors then I recommend you look into your alternative options.
