If you are here to know about the PCA service or facility of RCom and got a message of “PCA facility has been deactivated” or “Success, PCA service has been activated”. We have the answer. \n\nPCA is actually Pre Call alert facility from Reliance Communication for all its customers. This is a service which is auto activated and deactivated from Reliance depending upon the condition of Roaming, Bill due, Expiration of pack etc. \n\n\nReliance reminds you about any certain thing via this facility. For example if your bill is due then they activate this PCA and whenever you make calls they remind that Bill is due. \n\nIf you got text of its activation and deactivation, no need to worry. This service is anyway a free service and reliance will not charge for it. \n\nIf there is any service which you want to know about in detail, ask in the comment section below.
