    Hi and welcome to WPCentral. I'm sorry to hear you are having SIM issues. What carrier do you have?

    I've been having the same problem since the 8.1 update on my HTC 8X. Hopefully when HTC releases official updated ( as they've said they will) it will fix this issue - if the issue is isolated to HTC 8X

    I am having the same problem with my L920 WP8.1 developer preview on Rogers (Canadian carrier). Three times a day I do a hard reboot and it works for a bit, then I get a "sim card error".

    I'm also having a SIM card issue after 8.1 Lumia 925 on AT&T. I've had to exchange two thus far. I'm not sure which one I fear more - rampant hardware issues or a software problem with 8.1 :(

    Has anyone found a solution for this issue .... Lumina 1520 randomly dropping off the cellular network with SIM error, no SIM card detected? Shut the phone off, wait 30 seconds, turn it back on, and the cellular connection is back, full service as if nothing had happened. Anybody??

    I exchanged my sim card for a new one and it seemed to work (but have recently moved over to the L830)

    Im having the same issue - Nokia Lumia 920 - fully up to date - Orange EE - 3G UK carrier - since the 8.1 update - my sim card will work for a few hours if im lucky and then just suddenly disconnect showing sim error / no sim detected - doing a hard reset occasionally fixes this issue but not always and not for very long
    is there a fix for this or am i simply better off selling the phone and returning to android / iphone ?
