Our products

Our consumer focused brands deliver discounted international calling solutions for a variety of segments on both landline and mobile devices

Mobile international calling with rates starting at 2p/minute

Working with most mobile network operators, Dial-a-Code is a cost effective service without requiring registration or commitment through a contract.

For a hassle free experience, consumers simply dial the number for their required destination and connect without any additional fees, or use the Dial-a-Code App.

Free or subscription based international calling

An international calling service which operates via an access code, Call 07755 allows our customers to use their in-bundle minutes directly which eliminates any additional or unexpected bills.

We’ve recently introduced a subscription service for calls to India, providing unlimited minutes for a small fee.

Cheap international calls
from a landline

Whilst mobile phones continue to grow in popularity, we at Core understand that some of our customers prefer using their landlines when making international calls.

Talking Number is a landline based service which allows our customers to call overseas through our access number. No sign up is required and billing is through national landline providers, ensuring a hassle free experience.
