Credit on the purchased OpenCall powered by O2 SIM card remains of course valid even after portation from another provider. Credit on the original number outside of the O2 network is unfortunately not transferred to Opencall, so we recommend you to use it before portation. Please just be careful that you have at least a minimal positive credit left otherwise the portation process from the original provider might not be successful.
If you are porting the number from the original OpenCall service on Vodafone network we will take care of the existing credit on your porting number and transfer it.
