A key technical aspect of Mobile Number Portability (MNP) involves the routing of calls or mobile messages (SMS, MMS) to a number once it has been ported.Various call routing implementations exist globally, but the International and European best practice employs a central database (CDB) of ported numbers.
The MAP SRI message contains the MSISDN number and with this MSISDN the HLR will obtain the IMSI. Because of past location updates, the HLR already knows the VLR that currently serves the subscriber. The HLR will send to the VLR a MAP PRN (Provide Roaming Number) message to obtain the MSRN of the roaming cell phone. Like that the HLR will be ...
E.214 provides a method to convert the IMSI into a number that can be used for routing to international SS7 switches. E.214 can be interpreted as implying that there are two separate stages of conversion; first determine the MCC and convert to E.164 country calling code then determine MNC and convert to national network code for the carrier's ...

The number was permanently forwarded and had no associated telephone line. As a means to obtain an inbound number from another town or region for business use, remote call forwarding schemes tend to be far less expensive than foreign exchange lines but more costly than using voice over IP to obtain a local number in the chosen city.
SMS Home Routing is a modification to the original GSM specifications that changed the way inbound (off-net) SMS messages are treated by mobile telecommunications networks. . Adopted by the 3GPP in 2007, Home Routing was devised to enable mobile networks to offer a full range of advanced services on both inbound and outbound SMS, giving more utility to phone users and enabling operators to ...
A SIM swap scam (also known as port-out scam, SIM splitting, [1] simjacking, and SIM swapping) [2] is a type of account takeover fraud that generally targets a weakness in two-factor authentication and two-step verification in which the second factor or step is a text message (SMS) or call placed to a mobile telephone.
