My sis lives in the US and pops over every so often. She's after a PAYG sim for when she's over here. It'll mainly be used for making a few calls and navigation, so data cost would probably be the priority. Also, I've heard that some sims cancel all the credit if it's not used in 6 months. This wouldn't be so much of a problem, but she would like to keep the same number if she didn't use it within that time.
Your advice would be much appreciated. Thanks.
