I have bought my Samsung S8 on contract from O2. However, I would like to pay for the mobile in full and upgrade to the latest Samsung S9. Please let me know how can I do this.
Secondly, my Samsung S8 is locked i.e can be used for EU sim cards only. Please let me know how can I unlock the mobile so that non-EU sim card can be used.
Danke,
Saad
