@Norasj , have you checked the self serve account and confirmed that it is active and associated with the SIM card you are trying to use? Finding network using a manual search simply identifies all networks that have compatible bands. If the SIM cards is activated properly to a network, selecting the network manually will enable a connection. You could try a different phone if possible. It would rule out phone related issues. If problem is repeatable, then it might be that the activation was not completed.
