My Data Mate / MyDataMate - Recognizable Tech Logo & Favicon

I’m refreshing a technology brand and need a clean, memorable visual identity that works everywhere—from the website header to the browser tab.

The brand is called "My Data Mate" or sometimes styled as "MyDataMate" - your preference in the logo.

Website is a global eSIM company (ie. you can purchase pre-paid data SIMs in all countries of the world).

Scope
• Design a horizontal/rectangular logo.
• Create a square variant built from the same graphic logic.
• Produce a standalone favicon/emblem that instantly evokes the brand.

Guidelines
– Simplicity first: think crisp lines, no visual clutter.
– It must be unique enough that the favicon alone is identifiable.
– I’m open to color recommendations; propose a palette that feels modern and tech-forward.
– Style is flexible—minimalist, geometric, or abstract concepts are all welcome if they meet the brief.

Deliverables
1. High-resolution vector files (AI/SVG) plus transparent PNGs.
2. Favicon package in standard sizes (16×16, 32×32, 64×64).
3. Square logo version optimized for social and app icons.
4. Quick mock-up showing how the favicon reads alongside the full logo.
5. Short rationale covering color choices and typography.

Please include a link to your portfolio of prior logo work, especially for tech brands.

Attached is a screenshot of the website minus the heading (didnt want to show the existing logo so that you can design your own style.. the heading is white if that helps)
