Dead sim cards? - HD2 Android Q&A, Help & Troubleshooting and Genera

I'm just wondering, if anyone has issues with a dead sim card during use of android?
Not sure if it's that my sim card just went bad or if it was from using android.
If anyone is in the same boat let me know, I know for sure my sim card is bad because I'm using a backup that works fine.

i changed 2 sim cards in last 3 month with hd2 . i think is related to flash.

no issues with my sim, this sim has gone with me through all my android devices.
if you are with tmous, it's free, just go to the store and do a swap

Oh they're free? Didn't know that, gonna have to get one tomorrow, I had been using this one since my. G1 now all of a sudden it gets no signal at all but my other ones does.

Problem: MicroSD missing on boot.

Hi guys,
I'm having a weird issue with my HTC Aria,
the micro SD card I'm using goes missing from time to time especially after boot. The system just refuses to see it, a physical eject and reinsert of the card is enough to get it to read for a while until it dissappears or until I reboot.
I've already tried formatting the card with the PC and in the phone, neither of which has helped the situation. Has anyone got some other tips of what I should do to sort this problem out.
Manually removing the card 3-4 times a day gets quite tiresome.
.
Is it a Class 2 SDHC memory? A friend was having similar problems with an 8GB card of those characteristics and the phone didnt recognized it, not even after eject and re-insert. Try if the same happens with a SDHC of bigger class (speed)
Actually its a class 4, it does it every restart

Have you tried another card to narrow your issue down to card or phone?

I tried a 2gb Samsung card, like the free one you get with the phone. That had no issues, so it looks like my Kingston 8gb is faulty.

It's the SIM card slot, but all other radio hardware is missing (even the mini PCI slot), so it is not going to work.
OK thank you it just makes no sense they would put it in if it didn't have one?

They've not really "put it in" rather "not taken it out". It's the same chasis as the 3/4G version so all they've done is reduced manufacturing costs by sharing a chasis between the two models.

Sd card transfer problems

I'm currently using an 8GB sdcard. I bought a 16GB and tried to transfer data. The first problem I have is that it takes forever to transfer it from my computer to the new card. I used a USB cord (new) and it still takes hours. Once it finally finished transferring I reboot and none of my data is there. What am I doing wrong?

Did you get the card from ebay? It's likely the card is a fake, or is just DOA.
of course ,i think the sd card is a fake,to change another sd card to try again

Download h2testw on windows and run it to check your SD cards validity

I bought the card from DailySteals.com. It looks like a legit card and my computer recognizes it.

Run that program above. Just because it looks good doesnt mean it is good, thats the whole reason these places make it look normal, so you think you are buying a real card.
And again, it could just be a bad card as well, contact the site and see about a return.
Will do.

The SIM card may be locked to the device it was activated on. I suggest going to a T-Mobile store to see if they can help.

i tried 3 sim card ... DId they lock all the sim cards?? .. thanks for the suggest i will go to t mobile today
It is likely that they lock the cards to the device that the card is activated with. It seems like it is the only possible reason that you can't use T-Mobile cards.

I went to t-mobile. They tried another sim car and the phones was the same no sim... the said that the problem was with the phone cuz the sim cards are news and working on other phones... i dont know why the problem is only with t-mobile sim cards.. they say that if the phone was from t-mobile they could change me for another phone but it is at&t.... do u you think that it will be any problem if i go to at&t and tell the that my phone is unlocked but it doesnt read t-mobiles' sim cards

They could help. Might as well try. It is a very weird situation. If other SIM cards are working with it, it shouldn't be the phone...

Yes the problem is only with t-mobile... but i will take the phone to at&t tomorrow

Is it possible that you didn't unlock all the bands on your device? There is a tutorial around here somewhere that shows how to unlock all the bands for use with absolutely any carrier. From my understanding it is different then just unlocking with a code.
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Yes but it should said invalid sim car or ask me for that code when i insert t-mobile sim card... but the phones says no sim.. it doesnt even read the sim.... and when u unlock with a code i think is like factory unlock cuz my father unlock his phone with a code and his phone works fine

Had no need for it???? If your on Verizon the phone is NOT going to work without it... If you bought it to use the Sim card slot then why not just buy an actual gsm version

i used a knife as well lol, needed the number off it to get the new sim activated on it.
I used tweezers to remove it from the phone
Yeah you def need that card if you're on Verizon. I was having problems because I took my sim out of my note 2 and put it in my 3 and it wasn't working until 30 mins later I figured it out. As soon as you pick up or purchase the phone it auto stops your last sim.

Mine came with a sim removal tool or some such.
Yes, mine came with a SIM preinstalled. This phone is an absolute pain to remove the SIM from.
I used a small flathead screwdriver to remove it.
Tweezers.

I just used the point of a knife to gently push down on the card and slid it out.
Guys can anyone confirm if the phone is unlocked?
I'm traveling soon to the caribbean and need it unlocked and UMTS 900 to use 3g.

I ordered mine from a local store and they needed your account to pre order. So as soon as they scanned it as picked up it was activated because I had no signal on my note 2. That's how I figured out was preactivated from the store

You guys realize there's a SIM card removal tool in the box, right?
Granted, I couldn't figure out how to use the damned thing for a while. Ended up figuring it out though and using my old SIM.

That is not correct. I'm using the same SIM in my Note 3 that I used in my S4, Note 2, and GNex. The beauty of SIM swapping is awesome for phone addicts.

Made sure my finger was dry then kept sliding my finger across the card really fast to create friction then it slid right out.
