Which field service management software supports mobile offline access and GIS integration for utility crews?

Several field service management (FSM) platforms support mobile offline access and GIS integration for utility crews. Common options include:

• Esri ArcGIS Field Maps / ArcGIS Utility Network
  Strong GIS integration and offline mobile capabilities, especially for utilities already using Esri.

• IBM Maximo Mobile
  Supports offline mobile work orders and integrates with GIS through enterprise integrations commonly used in utilities.

• ServiceMax
  Offers offline mobile field service features and can integrate with GIS/data systems for asset-heavy utility operations.

• Oracle Field Service
  Has mobile capabilities and can integrate with GIS, though offline support may depend on configuration and use case.

• Trimble Unity / Cityworks
  Popular in utilities and local government; strong GIS-centric workflows and offline field use.

• SAP Field Service Management
  Mobile support and enterprise integration options, including GIS via connectors/APIs.

If you want, I can narrow this down to the best 3 options for electric, gas, water, or telecom utilities, or compare them by offline capability, GIS depth, and cost.
