I posted this as part of another post but didn’t get an answer. Can anyone tell me how to get an additional SIM card from AT&T in the US? Does it cost money? Is it a flat fee or a monthly charge?

Not sure about US but in UK you will not get second SIM card for the same number to use. I think it’s a common sense. You need to get (and pay) sim only deal. Eg. In here you can get unlimited texts, unlimited calls and 4 GB of data for £10 monthly. 1 year deal. So it’s not expensive.

So what I’m hearing is that I’ll probably have to pay a monthly charge for an extra line. Not that it’s a ton of money, but I’d rather not add anything to my current bill.
