Lyca Mobile Promo Codes

Lyca Mobile offers a wide range of mobile plans and one time deals to fit different budgets and data requirements. The 20% discount on a holiday eSIM is the featured offer on this page and works well if you're travelling abroad and need temporary mobile access without a long term commitment.

Holiday travellers: The 20% discount code on a holiday eSIM gives you a flexible option for staying connected while away, with no lengthy contract attached.

Students on a tight budget: The 100 GB 5G Data and Unlimited Calls Student SIM Plan for €10.99 every 28 days is built for you, offering substantial data and unlimited voice calls at a student price.

Switching to Lyca Mobile for the first time: You have several strong options depending on what matters most. The 60% off Unlimited Plus Plan for 6 months is the biggest saving available across the switching deals. If you prefer a plan centred on Irish calling and texting, the 40% off Ireland Plus Plan for 6 months saves 40% on that option. The 54% off Go Unlimited 12 Months Plan gives 54% off if you want a full year at the lowest cost per month. The 45% off Go Unlimited Plan for 12 Months is a similar 12 month option with a slightly lower discount. You could also get one month free when you switch to the National Unlimited Plan.

Looking for a small data plan: If you need modest data use, the 3GB Data XS for €4.99 every 28 days or the 5GB Data S for €6.99 every 28 days are both low cost entry points. The National S 12 Month plan at €9.00 per 28 days (with 10% off the standard price) gives you 5GB data with the security of a year long rate lock.

Wanting bigger data without a long term lock: The 30GB Data for €9 every 28 days offers strong value if you use your phone heavily but prefer to stay on a rolling 28 day cycle rather than commit to a full year.

Planning to stay longer: The Ireland Plus 12 Month plan at €13.50 per 28 days provides 30GB data on a fixed 12 month rate, which is useful if you want to lock in your monthly cost.
