How much does Three Mobile Internet cost and what are data add ons?


If you don't have a data add on using mobile internet costs €1 per day for any daily usage up to 50MB.
After you use 50MB you will be charged at €1 per MB.
This rate applies to Bill Pay and Prepay customers.
Data add ons or bundles allow you to purchase an amount of data. Any data usage then comes from this bundle.
