Mobility, roaming and network failures 

Test mobility and roaming procedures across technologies  

Simulate real-world roaming behavior to check if the device under test selects the correct roaming partner and check network selection timing, including cell edge conditions.
Test mobility procedures across technologies such as LTE, WCDMA and GSM from a signaling perspective.
Reproduce prominent network failures and error scenarios such as attach rejects, service rejects and congestion failures.
