Two-line decision board
This page is an offline-readable procurement checklist, not an ordering portal. No carrier accounts, subscriptions, numbers or SIMs have been created.
$0: Wi-Fi-only GHOST ↔ GHOST
Samsung A and Moto B each get their own GHOST test ID. Both need internet on Wi-Fi. The lab is NOT a carrier-backed telephone number, and the encrypted data-channel demo is NOT audited.
$2.50/month equivalent per cellular line: annual prepaid
The Red Pocket official eBay storefront currently lists a $30/12-month plan including unlimited talk/text and 200 MB/month data. That is $60 upfront for both devices (before applicable taxes); annual payment is required. Physical SIM and eSIM choices appear but verify phone and network eligibility, activation restrictions, pricing and port eligibility before purchase. It is ordinary cellular service, NOT programmable GHOST VoIP or E2EE calling.
Approx. $2/month combined: two programmable VoIP numbers
Telnyx publicly lists U.S. local numbers from $1/month each. Voice usage, SMS enablement, compliance and possible $1.50 E911 per number are extra. This is the API-based route for future GHOST routing and CRM. The current app has no provider integration; no numbers are reserved.
Decision matrix
| Path | Minimum spend | Real mobile service? | Programmable into GHOST? |
|---|---|---|---|
| Existing Wi-Fi + internal IDs | $0 additional | No | App-to-app only |
| 2 annual prepaid Red Pocket lines | $60 upfront / year | Yes, if compatible | No carrier signaling access; open native dialer |
| 2 Telnyx programmable numbers | From $2/month + usage | VoIP, not mobile SIM | Yes, requires secure backend development |
Port Straight Talk safely
- Do not cancel Straight Talk first. Confirm the phone is carrier-unlocked and supports the replacement SIM network.
- Confirm current number owner and port-in eligibility; get Straight Talk account number and number transfer PIN in the official account process.
- Choose the destination carrier and verify the full first-year charge, new-line versus transfer restrictions and replacement plan's renewal terms.
- Initiate a port at the new provider. The old line will typically deactivate after successful port. Do not port the number if it is essential for account recovery until MFA is migrated.
- For Wi-Fi-only testing, use airplane mode with Wi-Fi manually turned back on. Never assume a PWA can control physical SIM/eSIM configuration.
Security gates
No SS7 access, SIM duplication, ICCID collection or signaling manipulation. Never use this alpha for 911, protected customer information or sensitive operations. PSTN voice/SMS is not GHOST end-to-end encrypted. Review 911 requirements before any interconnected VoIP public launch.
