Do you need to activate the device with a US carrier sim card before using it with international sim card?

No. I put in my Caribbean sim and it worked just fine. I never put in a US sim.

No, you will need to see your carrier (GSM carrier in US such as AT&T; or T-mobile) to get a micro-SIM card.

I'm not sure. I'm in the U.S. and the device works fine. You should check with your service provider as you will need some type of wireless service in order to activate/ use the device.

No you don't, however in order to set up the device you have to use your visa to activate and they charge you a fee. My understanding in purchasing this was that the first month is free well its not. It only works in the US too

No, you don't have to activate it to use features other than calling. It will prompt for activation the first time it's turned on but this can be bypassed.

I got mine in the US precisely so I could activate it in the US before going to China, and have working Chinese mobile service the minute I landed in China. And that is what I did.

I don't know. Mine was tied to Verizon; others in the US are tied to another carrier. That matters because of the network the US companies use. For instance, you can't use a Verizon phone with an AT&T; or Tmobile plan. I do not know the requirements outside of the US for phones. I am told that a SIM card will take care of that, but have no experience with that.

No - to activate you must first press the start button on the device and then press the start button on the phone app when it launches ( also, phone must be unlocked prior to device start)

It requires microSIM. After you put in the Sim card it will require activation from the service provider and you shiuld be good to go with same phone number and data.

Check with your provider. I believe you need US Cellular to use this phone.

You need to call the phone number provided in the activation kit to activate the SIM card first.

If your service provider allows international call you should not have any problems. I used my phone to call the U.S. from the Republic of Panama but I am using a pre-paid sims.

Yes, the old sim card will work. You'll still need to get your mobile carrier to activate the phone, but it should be straightforward.

No, unfortunately the SIM card expires and it won't be useful at all.. You've to know how long you'll stay in US before buying it. The expiring time starts when you active the SIM, via sms.Bye

Yes because it's AT&T , it has a sim slot. But if you're gonna go over seas, you need to unlock it first !

Yes, you can. I did not use the one I purchased, but I tested it with AT&T; SIM card before I sent it abroad for a friend

Yes! If you purchase the unlocked version.I use a T-Mobile SIM (micro; they switched me to micro for free.) when I'm in the US.And, it works in all other countries that I've traveled in.Regards
