When will my Pre-Pay offer activate and can I change offers after I top up?

Your prepay plan will activate only AFTER you have sent the relevant opt-in text message.

Please note: If spend any of your credit before your offer activates, this could potentially reduce your balance below the required amount for your offer.

You can change your offer but this cancels your current offer and you will lose any remaining days on the offer.

If you wish to change your price plan, please contact eir Mobile Customer Care or chat to an agent here

Will I lose my number if I don't top up?

If a number isn’t topped up after a period of time the number will eventually be recycled.

If you do not top up your number within 90 days, the number will go into a temporarily barred state. This can be solved by topping up by a minimum of €5, as soon as possible.

After 150 days numbers that have not been topped up will be unable to make any outgoing services. The number will still be able to receive information (such as calls and texts) for 30 days.

240 days after your last top up any credit left on your phone will be removed.

13 months after your last top up your number will disconnect. It will not be possible to reconnect your number after this period of time as your number will have been recycled.

Other helpful information

It is recommended that you top up before the end of your 28 day prepay offer, in order to avoid a disruption to your service or offer.
