I have been using o2 Multicard facility for some time now. I figured out that I now don't need the second SIM card anymore and decided to deactivate it.
After deactivating the second SIM card, my main SIM card is blocked. There is no way I can unlock the main SIM card.
Please could you help me in unblocking my Main SIM card.
Looking forward to your response.
Thank you very much.

No, I deactivated the right one. Everything is perfect now. Main sim card is not blocked anymore.
