I can only text to other iphones?
Open the Settings App > Messages. Make sure Send as SMS is turned On.This assumes you have text messageing with your carrier (true?).

The iPhone can text other iPhones using iMessage. If you have set MMS and SMS to On, try contacting your carrier and having them make sure everything is setup correctly.
