Copying 3G SIM Cards

I just bought a 3G SIM card from AT&T who is not my carrier but I do have an unlocked TyTn. My current carrier doesn't support 3G yet but will do so in the near future.
Is it possible to copy or clone my current SIM card onto the AT&T SIM and get 3G services while roaming on a 3G network? If so, how can it be done? Or is it even possible?
Thanks!

Adding Verizon to Network Operators?

I unlocked my MyTouch 4g (Glacier) and I want to use my Verizon sim card in it but it does not detect Verizon in the network operators. How do I get verizon on there? Is it possible? I thought unlocking it would allow me to do this.

Verizon does not use 'SIM' cards
as 'SIM' cards are used for GSM networks and Verizon is a CDMA provider

I did google this extensively. The phone that I have here is on the verizon network and has a sim card. Why would I make that up?

Verizon is a CDMA network. The SIM card is there because the phone you have also has a GSM radio for traveling overseas. However, just because it says "Verizon" on the SIM card doesn't mean your phone connects to Verizon when you roam. It's actually connecting to Vodafone when you're roaming in most countries. That's what the SIM card slot is for. Now if you unlocked that phone, you could use it on T-Mobile or AT&T if you set it to GSM Mode.
That Verizon phone will work in the US and Canada whether or not that SIM card is in there. It's impossible to get a GSM phone (your MyTouch 4G) to work on a CDMA network (Verizon).

Thank you for the real explanation and not being a jerk about it, as I did not know this.
It sucks that I cant use it but now I know.

this sim card is not recognized

Hi,
i got a verizon thunderbolt and want to use it in germany with gsm/umts network.
Its showing all the time, "this sim card is not recognized" (emergency call only).
is there anyway to get gsm / umts radio on it?
Please help.
thanks.
Good luck with a phone that won't work correctly over there. The SIM slot IS NOT for GSM network use. It is for LTE, you CANNOT use it on a regular GSM network.
What g00s3y said. You can only use your ThunderBolt sim with other ThunderBolts or other LTE phones that will come out.
Sorry

[Q] hardware differences between US verizon 3g and UK 3g

Hello all
i have a verizon 3g xoom. it's not upgraded yet. i live outside us
about the UK 3g xoom, can it operate 2g sim card? for sms, gprs or ...
how about normal 3g sim cards?
is there any hardware difference between mine and uk one?
may i operate my 2g sim card on my xoom? how about 3g?
when i put sim card nothing happen. i just tried 2g sim card
our 3g operator is not started selling sim cards ... but we have 4g operator.
if i install uk xoom's rom on my own, can i use sim card?
is there any mini pci-e card that i can use my sim card with it? (self upgrade xoom with custom mini-pci-e)
please help me. i need some information. i'm confused.
http://forum.xda-developers.com/showthread.php?t=1263634
how about this thread? i've done that but dont work for me. there is no signal, i think it didnt recognized my sim card.
if i install the mini-pci-e card that motorola installs on xoom during upgrade, can i use sim card for 2g/3g ? (sms or internet)
i have found this : "If you bought your Xoom from Verizon, it will have no SIM card slot. Verizon's CDMA network doesn't use SIM cards. Also, if you bought the Verizom model, it will only work on Verizon, and not another carrier. There is also a WiFi-Only Xoom, and it does not have a SIM slot."
here : "http://www.ifixit.com/Answers/View/53440/Why+I+can%27t+find+3G+SIM+Slot+in+my+Motorola+Xoom"
but mine have sim slot with a plastic sim on it.
The Verizon 3G Xoom does have a sim card slot but no hardware inside to read the sim card. That is what the 4G upgrade was for, to install the hardware necessary to utilize the sim card for the Verizon 4G LTE network.
I don't know if anyone has gotten a Verizon Xoom working on any other carriers network.
Theres pix of the inside of my Uk3g Zoom somewhere...

[Completed] Can a cdma phone (with a sim card slot) be flashed to allow gsm carrier sim cards

i bought a Us Cellular phone off ebay and since it has a sim card slot, i assumed it would work with my gsm sim card. it didnt. my question is that is it possible to flash it from being cdma to work with a gsm sim.
Hi, thank you for using XDA Assist. Generally it is not possible. Whether it is cdma or gsm is hardware dependent.
