HT4994 My phone suddenly is showing "no sim card"?

I haven't had any issues with my phone and it's suddenly saying there's "no sim card" even though it's in there. I've restarted, restored from back up, took sim card out and put back in, among other things. Does anyone have any suggestions on what to do?

Hi Slh1078,
That's not good! Have you tried removing/adding the Sim Card in this the device? Any liquid physical damage to the device? Did this start after downloading any particular application?
Thanks,

Use a supported SIM card.
Remove/re-install the SIM.
Try a different SIM.

You could try removing the sim card and cleaning it - then put it back.
I assume that there is supposed to be a sim card in your model of iPhone 5 ?

I can barely hear callers, bars frequently X-ed out, showing no Sim card

Just recently I can barely hear the caller on my Droid DNA. I have not damaged my phone in any way. Also it starts showing no SIM card. I will restart and then that will fix itself but the volume for the caller barely exists. My volume is turned up. I have no problem hearing ring tones, etc and people can hear me. Also my bars will sometimes just x out and I have to reboot again. I am sick of not being able to hear my callers. Help!!!!

A few things to try:
Remove the SIM and reseat it, then restart the phone.
Go to a Verizon store and have them replace the SIM with a new one (it's free)
Try a system cache clear (instructions below)
Set your preferred Network mode to LTE/CDMA
System cache clear:
Power down phone
Hold volume up/down & power simultaneously until you see the Boot Mode Selection Menu
Use volume down to navigate to 'Recovery', use volume up to select
Should see screen with triangle and exclamation point next to an Android
Press volume up/down simultaneously to go into system recovery
Use volume rocker to navigate to 'wipe cache' and use power button to select
Once finished, use volume rocker to navigate to 'reboot system now' and use power button to select

Please help out to solve this problem.
It sounds like the phone was hacked or jailbroken, and updating it locked it to the original carrier. As it is not possible to update to any version other than the current one (5.1) the fact that you updated to 4.1 pretty much confirms the phone was hacked. There is no solution that you can get in an Apple forum.

All iPhones sold in Japan are carrier locked. The Japanese carriers do not offer unlocking.
You can not use that phone on a carrier other than the one it is locked to.
Sell it and buy one you can use.

My device showing invalid sim card what is the problem

sir i have a iphone 5s device with IMEI of 358805053170932,the device is brought from US ,And now currently in india ,the device carrier is Locked with US network provider Cricketer ,i did the country unlocking of the device but still the device showing the sim card is not valid what can i do to use the device

And how did you "unlock" the phone? Only the carrier can unlock the phone. And according to this Cricket does NOT allow for unlocking. In any case you will need to contact them. Apple does not unlock phones and there are no "codes" that unlock the iPhone.

Dear sir
I bought my iPhone 4 from Apple store in Charlotte N/C about 2years ago without contract.
Now I tried to upgrade it to iOS 7.0.4.but after that my phone not work with last sim card.
And invalid sim appeared.so I bought it without contract but it seems to be lock in my country
Please tell me whats the matter?
My phone serial no 86034HTCA4T
Modem firmware 04.12.09
Thanks

Without contract is not the same as unlocked. The update to iOS 7 relocked
the iPhone to the wireless carrier to which it was originally locked. You must
contact that wireless carrier to see if they offer unlocking and if you qualify.
If you used jailbreak or other hack to unlock the iPhone initially, the method
used may prevent a legitimate unlock from succeeding and may render your
iPhone unuseable.

I damaged my iPhone 4. I have ordered a new 4s. I never backed up or synced my contacts onto my sim card. Do you have to do that manually or will my contacts be on my phone when I put my sim card in the new iPhone 4s?

The iPhone under normal circumstances does not store contacts on the SIM Card. It can read them, but again under normal circumstances does not write them to the SIM Card.
When you sync your new iPhone to iTunes on your usual computer you can restore from a Back-Up of your old iPhone to get Contacts and other data and files installed on your new iPhone.

Toggle Airplane mode On and Off.
Try turning iPhone off and then on again.
Check for a carrier settings update. Tap Settings > General > About. If an update is available, a prompt will appear.
Remove the SIM Card and verify that it is a valid, carrier-manufactured SIM. Also verify that it is not damaged, worn, or modified. Then reinsert it.
Restore the iPhone.
Have a nice day,

You need to unlock iPhone by the carrier first to read a different SIM.
