I keep receiving text messages from id saying 'Calling abroad from the UK is chargeable and is not included in your standard allowances or add-ons. For international calling rates, please visit our international call charges page: https://www.idmobile.co.uk/help-and-advice/international-and-roaming-charges'
I have also logged into the app for my account and it says my upcoming bill has some additional charges (however I cannot see what they are for). I have not been out of the country so I want to check if I'd thinks I am roaming and are charging me (I have turned off roaming on my device). There seems to be no way to contact ID for this help.
