Losing signal on my HOX

This is weird. When I woke up I restarted my HOX and suddenly signal kept dropping. Keeps saying preparing sim card. What could be causing this? I don't want to keep factory resetting. Seems to be a really great phone but now I don't know if I should return it. Please if anyone can help.

Got exactly the same thing, was told by HTC it was faulty. Send it back for a replacement.

are you using a call blocker? I was getting weird issues when using root call blocker. I had to uninstall it, had read from the app devs they are working on the problem

mine is still stock, but I only had problems after I updated 2-3 days ago
had really great signal before upgrade... havent tried restoring fabric settings, but am searching for custom rom, and will try that out

Already happened to me three times where suddenly "preparing sim card" appears and I lose signal. Had to hard reset all the time. Unfortunately, htc shops here in the Philippines are crap. They say they have to send it to service center even if the phone is a week old. For what? So they open it up? I don't want to have a week old phone opened and fixed. I want a replacement.

Have the phone for 2 week now, and today i also faced this problem for the first time T_T (running stock 1.28)
Just great, first the yellow spots that didn't went away and now this problem on top of it ?
I hope it was a coincidence and hope i won't get worse.

I had my microSIM replaced and so far, crossing my fingers, signal has been full almost all the time. I just had the original SIM cut before, so I hope that was just the problem.

I've read about sim cards been cut to micro sim been a possible cause.

Similar fault here with factory micro Sim

In Slovenia one carrier has this problem. Only SIM cards older than 2 years work so it is a SIM problem. When I asked them about when they will solve this they told me it's HTC's problem and that HTC is working on the problem. Maybe the next update will fix it. SIM cards of other carriers work ok. So if you can, try cards from other carriers. If anyone knows how to fix this I'd be grateful. I don't want to switch my carrier because other two's 3G network is [email protected]

Galaxy Nexus not recognizing sim card...

Hey guies,
Just got my GNEX in the mail today, popped my sim card in, turned it on, and I get this BS "no sim card." After taking the sim card out and putting it back in I got it to work eventually. However, after updating to 4.0.4, it stopped working again.
I'm on SM.
What do?

Try a new sim card. If problem still persists, exchange phone.
butter and jelly please...

Popped a T-Mobile sim card in, and it started working. Doesn't recognize the Simple Mobile sim tho, but my other 3 phones do... I noticed the SP sim is a little smaller too, just a tiny but smaller. Maybe the contact aren't lining up.
any suggestions?

You must be mad getting your phone and having it not work. Mine officially shipped today. Try moving your simcard into different positions. You said sm Sim is smaller so maybe push it up more if that makes sense?

Call Simple Mobile and ask for a new sim. You should be able to keep your number

It doesn't matter. It's defective. I had a bad SIM for over a year (didn't know I could just replace it). It didn't work at all on my Android phone but worked on every other phone I tried just fine. I had to restart my phone into airplane mode and wait about 20-30 seconds before it would work. When I got my Nexus it didn't work at all so I finally replaced the SIM and it works just fine. So just replace it.

I tried another sim in my GNex and saw this issue temporarily. I also use simple mobile, like the cheap plan but hate the custservice.
Try this...take the battery out then the sim. Put the sim in then the battery and power on. I then toggled wifi a couple times and it detected the sim.
I have not seen the problem again but have only removed the sim once since then.

Well if it doesn't work on the GNex, it's defective.

It's working perfectly fine now, thank you.

SimCard Removed?

I've been having this issue since i got my S3 a few months ago. No matter what ROM I run, my phone randomly restarts and Gives me the "no sim card" notification.
I believe the problem is caused from my micro sim card (iphone 5 sim card, really tiny one). However, I'm wondering if maybe this isn't happening from my sim card? I notice most times it occurs is when i enable or disable data connections, but I can't really call it. Does anyone know if this issue actually is from my sim card being the tiny one or is it a phone problem?

Go to T-Mobile and swap it out. If it continues its not the SIM.

Yeah...
Anyone have the micro sim card and have any issues? Its obviously not the right size for the phone but it fits well enough to work. The reboots happen randomly (sometimes when the phone is just sitting on the tabe untouched). I'm thinking the problem may not be the sim since the simcard never really moves out of place. And I recall reading someone have the same issue of getting a "no simcard" notification after messing with data connections. So does anyone have any experience with such an issue?

If it's not the right size, it's not the right SIM. Even if you think it's secure, I'd lay odds that it's not and is the cause of your problems.
Chances of finding someone set up like yours is very slim btw.

Sim card error (not inserted)

Anyone seeing a SIM card error on their phone that it is not inserted? I got my phone the week it was released and this error just started popping up yesterday. I've seen it a handful of times since then. Sometimes it would go away on its own. I'm wondering if it is a network, hardware, or software issue.

Try new SIM? They r free

Try a layer of sellotape on side of the sim with no contacts. Carefully trim tape to make sure no overlapping. This adds extra thickness to the sim. I had to do it myself and it's no longer a problem.

Yeah I've had that problem. Not sure what I did to fix it as it went away by itself.

Theres a couple of troubleshooting options mentioned in that thread to even having to get a new sim, from simply going on sprint.com and going to chat and having them reactivate it. Read it, might help, Might not.

I got a new sim card for a different reason but after replacing the sim card that's when I got the sim card errors.

Lol... not at you, just.. the irony in it. But yeah, even in that thread, just like you, one of the 'solutions' was just that in time it simply goes away.
Hopefully thatll be the case here.

Have had the phone a few months now but the sim errors have been in the last few weeks. Sprint tells me its not a known error for the note 4 but the web says otherwise. They say just reboot the phone and your good to go.
When i had sim errors with my g2 it was the slot it sat in. I ended up with two g2s in 4 months time.

I had this happen too. I didn't root right away (I got the phone launch day in US) but soon after rooting it started. And it came back again after the NK2 update.
I used a strip of 1/4" kapton tape to hold my SIM card in place. But first, I powered down, removed battery, held the power button down a bit, grounded myself momentarily while holding the phone, removed the card, cleaned it with a micro fiber cloth and reinstalled it. The tape was applied following all the angles of the slot and battery slot. Since that day, no more SIM card errors.
I wouldn't recommend trying to modify the slot or add thickness to card. Those slots are sensitive. The tape simply holds the card in place.
If the SIM error ever comes back, I'll go into chat and ask for a replacement.
