To check if you have an MDM profile installed: 1. Open Settings in your iPhone. 2. Tap **General > Profile and Device management** (sometimes only **Profile**). 3. The **Management Profile** under **MOBILE DEVICE MANAGEMENT** is your MDM profile. 4. Contact your IT manager to have the MDM profile removed. ![](https://cdn.document360.io/20248637-fef6-4111-82b6-c3bf43c0155e/Images/Documentation/app-fails-to-install-on-an-ios-device-image-xixpypgb.jpg?sv=2026-02-06&spr=https&st=2026-11-10T16%3A38%3A40Z&se=2026-11-10T17%3A38%3A40Z&sr=c&sp=r&sig=OGW%2Bo9DLgqkzL%2BMbF3aBk%2FRNbh0kSC23FPA27Mp9%2Bs8%3D) If you do not see the **Profile and Device management** option under **General** settings, it indicates that you do not have an MDM profile in your device. ![](https://cdn.document360.io/20248637-fef6-4111-82b6-c3bf43c0155e/Images/Documentation/app-fails-to-install-on-an-ios-device-image-n3qmnuxh.jpg?sv=2026-02-06&spr=https&st=2026-11-10T16%3A38%3A40Z&se=2026-11-10T17%3A38%3A40Z&sr=c&sp=r&sig=OGW%2Bo9DLgqkzL%2BMbF3aBk%2FRNbh0kSC23FPA27Mp9%2Bs8%3D) In this scenario, verify that the UDID that was used to provision your account is still active. If you have switched phones, provide the UDID of your new iPhone to Smarsh for reprovisioning.
