Yes, 0808 numbers are free to call on all UK landline and mobile networks, nor will inclusive minutes remaining on your balance be used instead of a charge, thus making them truly free of charge.
Telephone numbers starting with 0808 prefixes are known as ‘freephone’ numbers as they are completely free of charge from all UK landline and mobile handsets. However there are two important exclusions to be aware of: firstly calls from public payphones may not be accepted plus international calls to 0808 numbers will still be charged, potentially at very high rates unless you have a roaming package on your tariff.
