Two Different Products Solving the Same Problem
A virtual phone number or DID is the raw infrastructure a dialer or CRM needs before a single outbound call can go out. Twilio and VoIP.ms both sell that infrastructure, but they are built for different buyers: Twilio is a developer-facing API platform priced purely on usage, while VoIP.ms is a more traditional, budget-oriented VoIP provider.
Neither one is a full dialer platform on its own. Both sit underneath whatever dialer or CRM software actually places and manages the calls, which is a separate cost covered elsewhere.
Twilio’s Actual Usage-Based Pricing
| Item | Price |
|---|---|
| Receive a call | $0.0085/minute |
| Make a call | $0.014/minute |
| Send or receive an SMS | $0.0083/message |
| Local US number | ~$1.15/month (commonly reported, not on Twilio’s own top-level page) |

| Item | Price |
|---|---|
| Voice number | ~$1.10/month |
| Outbound calls | from $0.005/minute |
| Inbound calls | from $0.009/minute |
VoIP.ms positions itself as a budget SIP-trunk and VoIP provider aimed at cost-conscious small callers, distinct from Twilio’s developer-platform, API-infrastructure positioning.
What 1,000 Outbound Minutes Cost on Each Platform
At Twilio’s $0.014-a-minute outbound rate, 1,000 minutes of outbound calling costs $14.00, plus the roughly $1.15 monthly number fee, about $15.15 total for the month. At VoIP.ms’s $0.005-a-minute outbound rate, the same 1,000 minutes costs $5.00, plus the roughly $1.10 number fee, about $6.10 total, a gap of roughly $9 a month at this volume.
That gap widens with scale. At 10,000 outbound minutes, Twilio runs roughly $141.15 for the month, $140.00 in call minutes plus the number fee, while VoIP.ms runs roughly $51.10, $50.00 in call minutes plus its number fee, a gap of roughly $90 a month at that higher volume.
What the Price Difference Does Not Tell You
Raw per-minute savings are real, but they are not the whole decision at actual cold-calling volume. Carrier reputation management, whether a number gets flagged as spam-likely after heavy outbound dialing, and the developer or API complexity of managing numbers directly, both matter more at scale than the per-minute rate alone.
A wholesaler dialing at real volume who picks the cheaper per-minute provider but has no plan for managing carrier reputation can end up with numbers getting flagged and connect rates dropping, a cost that does not show up on the pricing page at all.
What this means for you
- Twilio prices at $0.0085 a minute to receive and $0.014 a minute to make a call, with a local number commonly reported around $1.15 a month; VoIP.ms runs cheaper per minute across the board.
- At 1,000 outbound minutes, Twilio costs roughly $15.15 for the month versus roughly $6.10 on VoIP.ms; at 10,000 minutes, that gap widens to roughly $90.
- Per-minute cost is not the whole decision. Carrier reputation management and spam-likely flagging risk matter more at real cold-calling volume than the sticker price alone.
