Restart your smartphone (see Restart your smartphone).

Make sure you are in an area with good signal strength (see Signal strength is weak).

Make sure you have a data connection over the AT&T network. Note that you cannot send or receive multimedia messages over a Wi-Fi connection (see I don’t know if I have a data connection).

Check to see if you have data services enabled. Open Phone , open the application menu, and tap Preference & Accounts. Under Network, make sure Data Usage is set to On.

If you are in roaming coverage, check to see if you have data

roaming enabled. Open Phone , open the application menu, and tap Preferences & Accounts. Under Network, tap Data Roaming and tap Enabled.

Make sure the file you are attaching or receiving is of a supported file type (see Create and send a text or multimedia message or Receive and view text and multimedia messages).

Some wireless service providers have limits on the size of attachments to multimedia messages—check with AT&T to see if there are any limits. To check the size of a video you want to attach:

Open Videos and tap Video roll. Videos are listed by date and time, with the length and size of the video. To check the size of a photo you want to attach: Put the smartphone in USB Drive mode, navigate on the computer to the DCIM/100PALM folder, and check the size of the photo (see Copy files and folders using USB Drive mode for information on using USB Drive mode).

If possible, contact the recipient of the message, and make sure the receiving device can handle the type of message you’re sending.

If a message arrives but does not display a notification, make sure message notifications are turned on (see Customize messaging notifications).

I can’t set up an instant messaging (IM) account

To set up an IM account on your smartphone, you must already have the IM account established online. If you don’t, first set up the account online.

If you are logged into the account from another location, log out from that location and try setting up the account on your smartphone again.

If you are trying to set up a Yahoo! IM account, note that you can have only one Yahoo! IM account on your smartphone at a time. If you already have a Yahoo IM! account on your smartphone, you must remove it before you can set up a different one (see Use the Accounts application to edit or delete an online account).

Make sure you have a data connection (see I don’t know if I have a data connection).

Verify you have an Internet connection by going to a website (see Go to a website or Search for a website).

Make sure the account you want to set up is supported. See Set up an instant messaging (IM) account for information. If the account you want is not listed, or is not available in HP webOS App Catalog when you tap Find More, the account is not available at this time. Be sure to check back—your webOS smartphone periodically adds support for new account types.

I can’t send or receive instant messages

Make sure you have a data connection (see I don’t know if I have a data connection).

Contact AT&T to verify that your plan includes messaging services, that these services have been correctly activated on your smartphone, and that they are available at your location. (AT&T should be able to tell you if messaging services have been experiencing transmission delays.)

Check to see if you have data services enabled. Open Phone , open the application menu, and tap Preference & Accounts. Under Network, make sure Data Usage is set to On.

If you are in roaming coverage, check to see if you have data roaming

enabled. Open Phone , open the application menu, and tap Preferences & Accounts. Under Network, tap Data Roaming and tap Enabled.

Make sure your instant messaging (IM) account is properly set up (see Set up an instant messaging (IM) account).

Make sure you are logged into your IM account (see Sign in to an IM account).

If a message arrives but does not display a notification, make sure message notifications are turned on (see Customize messaging notifications).
