Does GSM support getting 2 locations from HLR?

Yes, GSM can support obtaining two locations from the Home Location Register (HLR). This is typically done through location updating procedures, where a mobile device can register its location in multiple areas, such as a current location and a previous one. The HLR maintains information about the subscriber's current location, enabling services like call routing and billing based on the user's location. However, the standard practice is to primarily track the current location for service delivery.
