Customer Services – 0344 809 02 02

Call O2 customer services 0344 809 02 02 from a landline telephone if you are unable to dial 202 from your O2 mobile. Callers can ask the mobile service provider about the remaining duration of their SIM contract before asking to upgrade to a new tariff that includes an up to date mobile handset. However callers can pay a cancellation charge to leave their contract early so that the O2 representative can offer a new monthly minutes package. Callers with a broken phone can enquire how to claim for the same monthly SIM package on a replacement handset. If you would like to keep your mobile phone number while purchasing a new O2 device then you can ask the advisor for a PAC code to do so. Alternatively you can call O2 customer services for basic account transactions such as to pay your bill or to purchase extra add-on data.

Callers can ask O2 about added costs such as international roaming charges or making a call to the UK from abroad.

Furthermore the O2 call centre is useful for new customers who would like to trade in their old handset to reduce the cost of a newer mobile or are interested in the company’s special deals such as those that offer free hardware including laptops. Alternatively customers with a lost phone can but a block on their tariff to stop any further calls or messages being sent from their mobile.

O2 customer services operates a non-geographic UK-wide 03 contact number meaning that all calls are charged the local rate from both landlines and mobiles. However O2 customers can contact a representative for free if they dial 202 from their mobile handset.
