Although theoretically a phone company can disable features via branding (VOIP is an example I know of) I don't think branding would stop you sending email on a PAYG SIM. What happens though is that they choose to disable data traffic quite often, we've had this sort of question come up in relation to GPS data, email is similar in terms of traffic. Mobile companies don't tend to restrict browsing traffic, partly because they have ways of driving customer towards their own online stores from which they can make additional revenue. Pure data is another thing though and is a more expensive resource. Regards.
