How do I opt in?

Simply choose the Simplicity offer that's right for you, text the opt-in code to 50104 and top up by the correct amount. Wait for two texts to confirm your top up has been successful and your chosen offer is active. Simple as that!

How long will my offer take to activate?

Your offer should be active within minutes, but you do need to wait for a confirmation text to let you know everything is active!

What's included in the Social networking bundle?

On the Simplicity 4G plans you will automatically get unlimited access to Youtube (until 31st March 2019), Facebook, Twitter, Instagram, Viber and Whatsapp without eating into your data allowance.

How does "more than you can eat data" work without eating into my 20GB 4G data allowance?

If you are on an eligible plan, it will be updated automatically so you can enjoy unlimited access to Facebook, Twitter, Instagram, WhatsApp and Viber messaging. You will also have unlimited access to YouTube until 31st March 2019.

How will I know my top up is due to expire?

The day before your offer due to expire, we will send you a text to remind you to top up. Once your account has sufficient credit on it on the day of renewal it will automatically renew. You can also schedule a top up by freephone 1740 and it will top up your account every 28 days to keep your offer active.

Can I move plans to get this offer?

If you are not currently on a 4G Simplicity choose one of the plans above. If you would like to move to 20GB 4G Data and unlimited calls for €20 top up, just text "20 calls and data" to 50104. To check what plan you are currently on, text "offer" to 50104

How do I check balances on my offer?

You can log onto myeir.ie and access your usage and plan details, download the myeir app or text "Balance Data" to 50104 to find out how much data you've used each month. To check days remaining on your offer text 'offer' to 50104

Do I get to keep my credit?

On our Simplicity plans your credit is used to pay for your data, calls and / or texts so when you top up your credit is deducted from your account. You can use eir's IOU for services outside of your plan.

I didn’t accept out of bundle data charges and I was charged for a day pass? What is the change?

Once you have used your data allowance you will automatically be directed to our data day pass which will be charged at €1.99 per 100mb, instead of being directed to an opt-in page to accept the out bundle charges. Our out of bundle data usage rate reduced from 99c to 2c per MB of data on 26th of September 2017. The out of bundle rate is the charge for any data used outside of your data day pass.

 Once you are opted into an offer, we will let you know when you reach 80% and 100% of your data allowance, and there are lots of great ways to check your data usage e.g. text 'balance data' to 50104 or log on to my eir.

Why are you making this change?

We want your data experience to be as seamless as possible, so we are removing unnecessary blockers. This is also a cost saving for you as we have dropped the rate from 99c per MB to 2c per MB of data.

Will I have to top up more often?

No, this is a price decrease so you will be saving money on any out of bundle data usage. If you opt in for one of our eir prepay data plans you can enjoy 20GB of data plus unlimited access to YouTube, social networks and messaging. See our plans here

How can I get the best value for my top up?

If you are a data user, then the eir prepay plans are great value. For €20 top up every 4 weeks you get 20GB data, unlimited access to YouTube, social networks and messaging plus unlimited calls and texts.

How will I know if I have used all my data?

If you are on a eir prepay plan you will receive an SMS when you reach 80% and 100% of your data allowance. There are lots of great ways to check your data usage e.g. text 'balance data' to 50104 or log on to my eir.
