I can’t make a data connection over the AT&T network

For help with data connections over a Wi-Fi network, see I can’t make a Wi-Fi connection from my home network. or I can’t make a Wi-Fi connection from a public or corporate network.

•Turn off Wi-Fi (see Turn Wi-Fi on/off). A Wi-Fi connection can prevent a phone service data connection.

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

•Check to see if you have data services enabled. Open Phone , open the application menu, and tap Preferences & 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. Note that additional charges may apply if you enable data roaming.

•Turn off the phone and turn it on again (see Turn wireless services off (airplane mode)).

•Restart your smartphone (see Restart your smartphone).

•If you are still having problems, contact AT&T.

Email

I have problems using my account

Occasionally you may experience problems using an email account after you set it up. If you followed the account setup procedure (see Set up email) and are experiencing problems using the account, verify that the account complies with your email provider’s requirements:

•Verify both your password and your username for your email account.

•If you changed your password in an online email account, you must change the password on your smartphone (see Change account login settings).

•Some wireless service providers have other requirements specific to their service. Check with AT&T to find out whether any provider-specific requirements exist.

•Make sure your email provider, ISP, or wireless service provider allows you to access email on a smartphone via POP or IMAP. (Some providers do not offer this option at all; other providers require an upgrade for you to access email on a smartphone.)

•Email provider settings may change. If your email account was working but you are currently experiencing problems, check with your email provider to find out whether any of the account settings have changed. You may need to manually change some email settings on your smartphone (see Enter advanced account settings).

I have problems sending and receiving email

•Make sure that your data connection to your mail server or email service provider has not been interrupted (see I don’t know if I have a data connection).

•Short periods of time when email is unavailable are common, due to server problems or poor wireless coverage. If you have problems sending or receiving mail for an extended period of time, check with your ISP or email service provider to verify that the service is working properly, and check with AT&T for outage information in your area. Tap the mail header in your account Inbox to see the last time the account was updated.

•For problems sending and receiving email using an Exchange email account, see the following sections:

•I have an Exchange account at work, but my data is not being downloaded to my smartphone

•I entered the settings to sync with Exchange, but I can’t synchronize with my company’s Exchange server

•A notification tells me that ActiveSync encountered a problem on the server

•A notification tells me that ActiveSync encountered a problem with [item type] [item name]
