The SIM has been working as she flew into Boston and texted from there.  It just seems to be the coverage from where she is.

If she selects other networks will that change the charges for texts or calls?

My email address is joebellett at gmail.com.

The UK number is +44 7509 658259 and the US number is +1 209 797 3536.

The zip code where she is is 05356.

Thanks.
