yes, or for that matter to a regular e-mail address too. i don't know anyone who doesn't include an e-mail subscription today.

this u might know, but since u only mention softbank and docomo, i'll say it anyway.
in the japanese mobile system no texting or SMS exist. u send a regular e-mail through, in the mobile phone embedded, e-mail client. the advantage of this system is that u can send e-mails to a computer too and u can receive regular e-mails from a computer, such as a gmail or any other e-mail provider. meaning that ppl in the US, AU or Europe can in theory always reach without actually calling u.
