# Refresh SIM connection

In a cellular network, a connection refresh involves resetting the link between a device's cellular modem and the network. This process typically requires detaching and reattaching to key network components, such as the SGSN (Serving GPRS Support Node) or MME (Mobility Management Entity) for data services, and the VLR (Visitor Location Register) for voice and SMS services.

{% hint style="warning" %}
Refreshing a connection is high-risk. Sometimes, the device may not reconnect to the network, requiring a full reboot to regain connectivity.

### Reasons to refresh a connection:

* Resolved connectivity issues.
* Update network parameters.
* Switch operator or technology.
