MetroPCS phones, like many other cell phones, have email addresses assigned to them that you can use to send text messages from any email program. Since MetroPCS uses two different domains – mymetropcs.com and metropcs.sms.us – the best way to figure out which one will work with your phone is to send a couple of email messages from a computer or from the email program on your phone. The one that arrives is the one that corresponds to your email address.
