Is there anyway I can move SMS from phone memory to SIM memory?
My sim card is in the phone but its saying there i no sim card... what should i do?
Try cleaning the contacts on the SIM, or go in for a replacement. Most places will not charge you for a replacement.
Hello guys...
I wonder if it would be possible to create a virtual sim slot or a switcher?So that we could save images of our real sim cards in our phone and them run them from our SD card or Main memory...
That way we could run multiple SIM cards or if not possible,just to easily switch between many SIM cards without having to turn off and disassemble the phone.
Thnx.
Ok, so i was explaining to my lil sister about sim cards, and as i was saying how only Verizon worldphones had sims, i realized that you could, in theory, put a Verizon 4g sim into a 3g worldphone, and.... what would it do? I'm a little hazy on how exactly Sim cards work, but would it be possible to artificially "create" a 4g phone using a 4g Verizon sim?
EDIT: ok, since there are no answers, i realize this is a noobish question, but does the sim card contain the actual 3g/4g/whatever radios, or does it just "enable" them?
The sim card contains the customer account information, so once you lock the signal verizon knows how to properly bill you for your usage.
4G sim cards are different than 3G sim cards although they are in the same format. You can't just swap your Droid 2 Global Sim card and expect to work in your Droid 3 or vice versa becuase the ESN is what is tied to your number, the sim card is just there for roaming purposes (i may be wrong on that one), but i know that even on the global phones, you must have the sim card inserted in the phone to be able to get service with verizon.
The 4G sim card works more like a REAL (GSM) simcard you can swap your sim card into another 4G device and your number will transfer.
Here is another difference, the same sim card on global devices can be reused like you can go to your account and transfer your phone to another account without the need for another sim card. The 4G sim cards become invalid once they are deactivated and you will require a new blank sim card in case you want to activate your phone number again (this usually happens when you switch from a 4G device to a 3G, then move back up to a 4G device), they work much like most GSM sim cards work.
So in sumary, the 4G sim cards works more like a real sim card.
So I noticed after taking my phone off airplane mode for so long that I have a no sim card inserted error
The thing is I do have a sim card inserted and the weird thing is when ever I take out the sim card, instead of the bars getting an X for disconnectedness, apparently I still have service. and I've been reflashing my tmobile d801 to gsm and not cdma
I've reflashed 3 different ROMS to see if it would get rid of this error but it hasn't.
I have taken my phone apart to see if the Sim card slot was loose and it's not and all the pins are fine
I've taken the sim out and turned the phone off for 1 minute and that didn't help
I have blew air in the sim card slot for curiosity and nothing.
I'm all out of ideas, anyone can help?
Could it be the modem?
