EU Roaming - No Outgoing Calls in Spain but worked fine in Poland??

Hi all,

Please can anyone advise on this, I have recently been in Poland and Spain. In Poland everything worked fine no problem, in Spain everything worked EXCEPT outgoing calls to UK landlines and mobiles:

Data - Fine

Calls to Landlines in Spain - Fine

Texts receiving and sending - Fine

Receiving Calls - Fine

Making Calls to UK Landlines and Mobiles - Not Working 😞

Just wondering why it would work fine in Poland but not Spain, I travel to another region of Spain in a few weeks so would like to make sure my calls will work this time.

Thanks 🙂
