The advice given was wrong. My addon of 500MG for trip in Ireland is not enoigh on June 22. How do I access more data for the remainder of my trip? I return to Canada July 2nd. Next billing cycle begins July 12. Thank you.

You will have to pay overage rare, which is obscene. Your only realistic option at this point is to get a local prepaid Sim for your data needs. There are excellent data options locally:
