How to configure O2 Ireland for an iPhone

What is O2 Ireland:

Telef\u00f3nica Ireland was a broadband and telecommunications provider in Ireland that traded under the O2 brand (typeset as O2). O2 Ireland was previously called Esat Digifone when it was owned by Esat Telecommunications (and Telenor) from 1997 to 2006. O2 Ireland became a subsidiary of Telef\u00f3nica in 2006, after its parent company O2 in the United Kingdom was purchased. In June 2013, Hutchison Whampoa announced it would acquire the Irish arm of O2 for \u20ac780m. O2 was merged into Hutchison Whampoa's subsidiary Three Ireland in March 2015.

1. Go to Settings > Mail then click Accounts.
2. Click Add Account > Other and tap Add Mail Account
3. Type in your name (can be any name), your email address, your password with a description for your account.
4. Click Next. Mail should now try and find the email parameters and finish your account setup. If Mail finds the e-mail configuration, tap Done to complete your account setup.

In case the Mail app can't automatically set up your account, it means that you need to enter them manually. We think you will find the following information useful:
