How to Switch Mobile Networks 

Before switching, always check to see if you have any outstanding bills with your existing provider. If you leave your existing contract before it has expired, you may be charged for the remainder of your contract.

How to switch:

Choose a mobile deal: Based on the information above, decide if you want a prepay or bill pay deal, SIM-only or bill pay phone.
Check your mobile usage: Check your current mobile bill or plan and see how much data and minutes you use every month. This will help you choose the right plan.
Compare: compare the best mobile deals from Ireland’s top networks above.
Choose your new plan: Once you pick your new plan, you’ll be taken to the mobile provider’s website.
Switch: When switching you may be asked whether you are moving from another network, or you’re a new customer. You may also be asked to fill out an online form, and receive a call to authorise your information.
Transfer your old mobile number:  Let your new mobile provider know you would like to keep your old number, and can assist with ‘porting’ your number over.

Is it worth the switch to 5G mobile plans?

Yes they are much faster than the 4G network but the coverage is much less in Ireland and is concentrated in major cities.
