The invention is applied to the technical field of network communication, and provides an acquisition terminal network mode switching method and terminal equipment. The method comprises the steps of:detecting whether an acquisition terminal is inserted into a full-netcom module or not; if the fact that the acquisition terminal is inserted into the full-netcom module is detected, supplying power to the full-netcom module, and judging whether the network mode selection type of the full-netcom module is an automatic selection type or not; if the fact that the network mode selection type is the automatic selection type is judged, selecting a network mode from pre-set network modes, and determining an APN corresponding to the full-netcom module according to the selected network mode; detectingwhether the full-netcom module successfully registers with a network operator corresponding to the APN or not; if the fact that the full-netcom module successfully registers with the network operatoris detected, dialling according to the APN; and, if the fact that dialling is unsuccessful is detected, performing network mode switching according to the network mode switching sequence in the pre-set automatic selection type. After adoption of the scheme, the construction, operation and maintenance human cost due to signal instability can be reduced.
