182 Chapter 11 : Troubleshooting
I have problems sending email (IMAP and POP accounts)
If you are able to receive email messages but cannot send them, try the
following:
• Turn on authentication (see Set up email when automatic setup fails).
Many service providers require authenticated access, or ESMTP, to use
their SMTP servers for outgoing mail.
• Enter the name of a different outgoing mail server for sending mail (see
Set up email when automatic setup fails). Many ISPs, such as cable
companies, require that you have an Internet connection to their network
to send email through their servers. In this case, you can almost always
receive email from these accounts, but if you want to send email, you
must send it through another server. Check with your email service
provider for the correct outgoing mail server name.
After I receive messages, older messages disappear from my
Inbox
When email sync takes place, by default, the last three days’ worth of email
messages is downloaded from your mail server to your Inbox. All messages
older than three days are removed from your Inbox; they are not deleted on
the server, however.
You can change the setting to download only one or two days’ worth of
messages. If you select one of these options, any messages older than one
or two days are deleted from your Inbox. You can also change the setting to
download all messages regardless of the date, in which case all messages
continue to appear in your Inbox (see Enter advanced account settings).
Messaging
I can’t send or receive text or multimedia messages
• Make sure that your phone is on (see Turn the phone on/off).
• For multimedia messages, do the following:
• Contact AT&T to verify that messaging services have been correctly
activated on your phone, 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 Preferences. 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. Under Network, tap Data Roaming and tap
Enabled.
• 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, restart your phone
(see Restart your phone).
I want to send a video in a multimedia message, but do not see
it on the list of items I can attach
You can attach pictures in JPG format to outgoing multimedia messages. To
send files of other types, attach them to an email message (see Add
attachments to a message).
Wi-Fi
I am trying to connect my phone to my Wi-Fi network and
need to find the phone’s MAC address
Open Device Info , tap More Info, and tap Hardware. Under Phone,
the number listed to the right of Wi-Fi is your phone’s MAC address.
