    2. If internet does not work, follow steps in Generic T-Mobile data settings.
    3. If the generic settings did not work, search the Non T-Mobile space for documents and discussions to help.
    4. If data and MMS are still not working, contact the device manufacturer for instructions on how to enter the settings.
