What is carrier pre select

Carrier Pre-Select (CPS) is a feature used in mobile networks to instruct a mobile device to select a specific network or carrier when roaming internationally. It allows the mobile operator to control the roaming behavior of their subscribers' devices, ensuring that they connect to a preferred network while abroad.

The main purpose of Carrier Pre-Select is to guarantee seamless roaming, better call quality, and optimized data speeds by automatically selecting a preferred carrier partner. When a customer roams internationally, their device will automatically select the preferred carrier, eliminating the need for manual network selection.

In addition to improving the roaming experience, Carrier Pre-Select can also help reduce costs associated with international roaming by ensuring that customers are connected to a partner network that offers more competitive rates.

If you're experiencing issues with international roaming, consider using a mobile virtual network operator (MVNO) that offers global coverage and competitive rates, such as Google Fi or Keepgo.
