Title: REDUCING ATTACH DELAY FOR A MULTI-SIM UE
Abstract:
Methods, systems, and devices are described for wireless communication. A modem processor of a user equipment (UE) may receive a switch indication directing the modem to utilize a designated SIM and may access identification (ID) information from the SIM, including ID information for a network operator. The modem processor may then retrieve a stored access point name (APN) associated with the network operator and establish a connection to the data network identified by the stored APN. In some cases, the APN may be stored in the modem processor after a successful connection to the data network using the designated SIM. In some cases, the UE may also identify a network priority rule associated with the network operator of the SIM and establish the connection to the data network based on the priority rule.
