FAQs about the Dublin eSIM
Will my eSIM work the moment I land in Dublin?
Install your Teraroma Ireland eSIM at home before you fly. The plan starts when your phone first connects to a local network in Ireland, as long as the eSIM line and data roaming are switched on.
Which networks does the Dublin eSIM use?
Our current Ireland plans connect to Eir. The network your phone picks depends on the plan and local signal.
Do I need a separate eSIM for other cities in Ireland?
No. Ireland plans are country-wide, so the same eSIM works in Dublin and anywhere else the local networks cover.
Can I keep my home number while using a Dublin eSIM?
Yes. Teraroma eSIMs are data-only and run alongside your home SIM, so calls and SMS to your usual number keep arriving.
What if I need more data while I'm in Dublin?
Top up your existing eSIM from the Teraroma top-up page. You don't need to install a new eSIM mid-trip.
