Hallo!
We already have a contract for SIM cards with O2 and received the two SIM cards last Wednesday. Now, we would like to add a phone to our existing contract. Our question is: How can we do this to minimize the monthly fee?
We understand that it is cheaper to order the phone together with the contract. However, since we have already received the SIM cards, we kindly ask for your assistance in finding a cost-effective solution.
Thank you in advance for your help.
Best regards,
J
