Abstract

The embodiment of the invention relates to the field of communication technology, and discloses a method and device for searching a network after roaming. Wherein, the method includes: judging whether the current network search mode of the terminal device is manual network selection; if the above-mentioned network search mode is manual network selection, counting the time when the terminal device is in the no-service state; if the time when the terminal device is in the no-service state If the preset time threshold is exceeded, the above network search mode is switched to automatic network selection. Implementing the embodiment of the present invention can automatically switch the network search mode from manual network selection to automatic network selection after the terminal equipment roams, so as to register with the home public land mobile network HPLMN, so that the user can normally use the terminal equipment for communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for searching a network after roaming. Background technique [0002] With the development of communication technology, people can use mobile terminal equipment to communicate anytime and anywhere. The process of globalization has been reflected in all aspects of life, people have more and more needs to travel or travel abroad. When you are abroad, you can use the international roaming service, so you can make and receive calls, send and receive text messages, and use data traffic without buying a local operator's phone card or registering a local operator's phone number. When in the state of international roaming abroad, the user often needs to manually select the network to choose the roaming destination that cooperates with the operator corresponding to the user's Subscriber Identification Module (SIM) card, has the best network signal or the most fa...
