Having problems with your email? Maybe you can receive emails ok, but you can't send?
If you use Gmail, Yahoo Mail, Hotmail or any other free web based email, then you don't need to make any changes on your phone. However, if you're email isn't sending or you're being prompted to continually enter your password, you should log into your email directly through the web browser on your phone using your email address and password. Further, if you're using Gmail and your mail app keeps prompting you to enter a password, or displays some other error message, you may need to perform an "unlock captcha" of your Gmail account at https://accounts.google.com/DisplayUnlockCaptcha.
If you use a work email or an internet service provider email (eg @bigpond.com, @anzbank.com.au, @optusnet.com.au) and you can't send emails, this is because of security settings set by your email provider and/or by the AT&T network. Whenever you send an email from any device (your laptop, iPad, Tablet or phone), the email is sent out through what is called a "simple mail transfer protocol" server (an "SMTP Server"). Your email provider (ie your work or your ISP) may prevent emails being sent from outside Australia. And to prevent people using the AT&T network to send millions of spam emails, AT&T only allow emails to be sent through their own SMTP servers so they can identify any spam senders.
There are two solutions:
1. The first solution, and the easiest, is to use your internet service provider's webmail. Most major ISPs have a website that allows email access via a web browser using your username/email and password. Just do a Google search with your ISP name and the word "webmail" - here's some links to the most popular ISP webmail: TPG Webmail, Telstra Bigpond Webmail, Optusnet Webmail, iiNet Webmail, Westnet Webmail.
2. Make a setting change on your device to use the AT&T SMTP server. To do this, go to the email settings on your device and change the outgoing mail server / SMTP server to:
Option 1
outbound.att.net
Port 465
(requires authentication)
SSL Checked
Option 2
smtp.mail.att.net
Port 465 or 587
(requires authentication)
SSL Checked
Please note that if changing the SMTP server settings doesn't work, then this is not a problem with the SIM card - it is a problem with your email server/ISP. Please contact your email server/ISP for more details. Alternatively please log into your email via your web browser/webmail.
