Why am I not able to send or receive messages?

There are a couple of things that can disrupt your ability to send or receive messages. Many of them you can fix:

  • Check your account balance: If you're not on an unlimited plan, you may just need to add money to your account in order to restore your text/MMS messaging service.
  • Keep your flip phone open: Phones that flip open and closed must remain open while the text message is being sent. If you close the phone while it's still sending, your messages will not be sent.
  • Use the area code: You must use the area code and phone number when sending a message.
  • Clean out your Sent and Inbox: The messages that you receive and send are stored on your phone and can take up space! Keeping them can interfere with your ability to send or receive additional messages. Check your phone user guide for instructions on how to delete messages.

What is MMS (Multi-Media Messaging)?

Multi-Media Messages are like text messages, except you can include a picture, audio, or video file. Some early Boost Mobile CDMA phones use a separate Media Mail Inbox to identify messages with attachments. Most new devices have an integrated Inbox and the device automatically switches to MMS Mode if you choose to attach media to a message.

Why does the phone automatically finish words for me when I'm writing a text message?

Your phone is set to predictive text entry; it predicts what you're typing and helps you finish the word. Some phones may also give you the option to choose from a list of possible words. 

To better understand, type the word 'happy' by pressing 42779 on the phone keypad.  Notice that as you entered each number the word changed a little until the final word appeared. 

If you prefer to enter one letter at a time, you can change the text entry setting on your phone. Changing this setting also allows you to enter numbers and/or symbols in your text messages.

How do I switch between words, letters and numbers when writing a text message?

All you have to do is change your text entry setting. Each phone type will use slightly different words to describe text entry settings. Most phones use 'ABC' mode' or 'Alpha' to mean one letter at a time, and "Word" to mean predictive text entry. Changing text entry settings varies by phone. If these steps don't work for you, consult your phone's user guide:

  • While you are entering text into a message, click on a softkey (usually 'options')
  • Scroll to select the new text entry type
  • Click on 'Select' or the center key.

How do I send a message with an attached audio, video or image?

The specific instructions vary by phone. Generally, for pictures you can take a picture and then look at the options by the right and left softkeys on the phone.  These will be the keys to the bottom right and left of the screen.  On most phones, there will be an option to send the picture as a message.

The easiest way to learn how to attach an audio recording or an image is to create a message and then look for softkey options that let you record audio or attach an image.

For more details, refer to your phone's user guide.

How do I send a text message from my computer?

To send a text only message to another Boost Mobile customer using email, place your friend's 10-digit Boost Mobile phone number followed by @sms.myboostmobile.com in the "To" or address field. It should look like this 1234567890@sms.myboostmobile.com. Your message will be limited to 160 characters.

To send an MMS message or long text message to another Boost Mobile customer using email, place your friend's 10 digit Boost Mobile phone number followed by @myboostmobile.com in the "To" or address field. It should look like this: 1234567890@myboostmobile.com.

To send text messages from your email to friends who have service with other carriers, you would typically enter the email address as the 10 digit phone number of the person you want to send a message to, followed by the carrier's address. You will have to ask your friend for the address used by their carrier.

If they reply, their message will go straight to your email inbox.

How do I send text messages to international numbers?

When texting to an international number, use the following number format, based on which type of phone you’re using:

  • Enter the plus (+) sign or (011)(which is the international access number in the U.S), the country code, the Mobile Designator Digit, if required, and then the wireless number.

NOTE: A few countries have started adding a digit to the phone number, which Boost refers to as a Mobile Designator Digit. The digit is used by the international carrier to identify the phone number as a mobile number. This digit should be entered preceding the phone number. Currently, Mexico, Honduras, and Thailand require the Mobile Designation Digit.

To address a text message to Mexico using a Boost phone, enter the following:
+521<wireless number> 
Or
011521<wireless number>

NOTE 1: Boost subscribers cannot send or receive text messages while in an international location at this time.

NOTE 2: When sending a text that is domestic; do not include the (+) plus sign in front of the 10 digit dialed number. The call may be rated incorrectly because it's interpreted as an International Call.

I am getting 'Transport Error.' What does that mean?

You may get a "Transport Error" if their message could not reach the messaging platform.

  • Turn your phone off and back on.
  • Change the size of any attached images to something smaller from the main Camera screen by selecting Menu and then Image Size. Once the image size is changed, try taking a new picture and sending that picture in a new message.

NOTE: Sizes for existing pictures cannot be changed.

  • You may have to wait about 15 minutes after turning the phone off and on or try in another area.

Why am I unable to reply to a message?

If you receive a text message that doesn't give you the option to reply, it is probably an SMS (Short Message Service) message. SMS messages do not have reply capability.
