Grok Bots now respond to SMS and voicemail. Works on flip phones, payphones, anything that can text or call.
The setup: Free Google Voice number + Gmail + secret passphrase. Text or call the number, say your passphrase + command, Grok processes it and texts back the result.
Use cases that actually matter:
- Internet down but 1 bar cell signal? SMS "what's on my calendar" and get data back
- Driving hands-free? Call, speak command, hang up
- Dead zone at a festival? Still have bot access via SMS
- Bots can also text YOU when something urgent happens
Security model:
- Only your phone number works
- 3 permission tiers: instant lookups, pre-approved actions that confirm after, and high-risk ops (money/deletion/new contacts) that require app confirmation
- Secret word never echoed, command messages auto-deleted
- Rate limited: 20 texts/day, 30min spacing (Google TOS protection)
Voicemail commands work now. Incoming calls from Grok coming soon.
No new hardware, no data plan required. Just Google Voice (free) and your existing Grok Bot setup.
This is basically API access to your AI agents over the oldest reliable channel that still works everywhere.
