Hi @User2003 


Check that your phone isn’t barred for use abroad using the My Vodafone app or My Vodafone online.

Vodafone uk travelling-abroad advice , costs and information.


Even though Vodafone Ireland use the same Vodafone name they are not linked to Vodafone uk.


Unfortunately when roaming Vodafone UK cannot guarantee everything will work. They have no access to another Vodafone Network.

A person can try and self help troubleshooting via choosing a different network in their phones connection settings etc.

Also the masts where you are could be experiencing issues and or mast congestion.

The issue is Vodafone Uk cannot access to check.

They should have an online mast checking service if you can access it somehow. 

Vodafone uk customer services on the phone or via Live Chat can however check your account. vodafone uk/contact-us.

If your phone is unlocked to all network's then as an interim solution you could choose to use a local sim card.

I wish you all the best with this situation.
