Ways to pay your airtime bill

Your device plan agreement is separate from your airtime bill and is paid by separate Direct Debit. For more information, please see our paying your device plan agreement support page.  

Paying your airtime bill by Direct Debit is easy. And saves you £5 a month. 

Your payment will come out 10-19 days after your bill date. The reference will be H3G. You can check your payment date on the Three app, My3, or your monthly airtime bill. 

Head to our Direct Debit support page for more information, including how to set up or change your airtime Direct Debit.

This isn’t available for your separate device plan agreement Direct Debits.
