Can I Contact Eir on Social Media?
Yes, Eir maintains active social media profiles and responds to customer queries on both platforms. Social media can be a useful alternative if you are unable to get through on the phone or prefer written communication.
- Facebook: facebook.com/eir — send a direct message for account-specific queries.
- X (formerly Twitter): @eir — useful for reporting outages or asking general questions.
When contacting Eir on social media, never share sensitive information such as your full account number or PPS number in a public post. Use direct messages instead.
My Eir Account & Mobile Apps
For self-service account management, Eir offers the My Eir online portal where you can view and pay bills, check your usage, upgrade your plan, and run broadband diagnostics. Eir also provides the following mobile apps:
- My Eir app: Manage your account, pay bills, check data usage, and contact support (iOS and Android).
- Eir TV app: Stream live TV and on-demand content from your Eir TV subscription.
- Eir Talk app: Make Wi-Fi calls when you have a poor mobile signal.
Tips for Getting Through to Eir Quickly
Contacting any large telecoms provider can be time-consuming. Here are some practical tips to reduce your wait time and get your issue resolved faster:
- Call at off-peak times: Tuesday to Thursday mornings between 9am and 11am typically have the shortest queues.
- Have your details ready: Your Eir account number, the phone number linked to your account, and a description of the issue will speed up verification.
- Try My Eir first: Many routine tasks — bill payments, plan changes, usage checks — can be done through the My Eir portal without calling.
- Use the right number: Calling the specific department line (e.g. 1901 for broadband) routes you to a specialist faster than the general customer care line.
- Note your reference number: If you are following up on a previous case, your reference number lets the agent pull up your history immediately.
- Consider social media: For non-urgent queries, a Facebook or Twitter message can sometimes get a faster response than the phone queue.
