Hello Everyone

sorry if this is going to sound like I am being obtuse.

Last year whilst holidaying in Texas, I bought a cheap Kyocera mobile phone, on virgin, to use for the duration of my stay.

I am due to come back to USA, and dug out said phone. I was thinking I could just buy a pay as you go sim when I get there, and slot it into the phone.

However, I took the back off the phone, and I cannot for the life of me see where the sim card is. Does this mean that it does not have one? If not, do I have any way to just use it as a payg? I don't want to buy a phone each time I come.

Or maybe my English phone would work if it is unlocked to any network, and then I buy a sim card for that?

Can anyone give me any guidance please?

Thanks
