How Much Does Enterprise SMS Cost?
At high volume, bulk SMS on TextSpot costs $0.0046 to $0.0065 per message segment in platform rates depending on monthly volume, plus carrier pass-through fees of roughly $0.0035 to $0.0050 per outbound segment, for an all-in cost of about $0.008 to $0.012 per message.
Those are real, published numbers, and they sit on a sliding scale that rewards volume. Sending fewer than 300,000 segments a month? TextSpot's standard plans cover that.
The published rate card
Only outbound messages are billed on the platform side. Incoming SMS carries no platform charge.
Bills both directions. Each inbound and outbound segment counts toward monthly volume at the band rate.
MMS runs off the same bands: outbound MMS is billed at 3× the tiered outbound SMS rate, and inbound MMS at 2×, per segment.
Rates are tiered, and each rate applies only to the messages inside that band, not to your entire monthly volume. Crossing into a higher band charges only the messages above the threshold at the lower rate.
Carrier Fees, Passed Through at Cost
Wireless carriers charge their own per-segment fees on business messaging, on top of any platform's rates. Most providers either bury these fees or blend them into a marked-up rate. TextSpot passes them through at cost, with no markup, and publishes them.
| Carrier | SMS outbound | SMS inbound | MMS outbound | MMS inbound |
|---|---|---|---|---|
| AT&T | $0.0035 | $0.0035 | $0.0090 | $0.0090 |
| T-Mobile USA | $0.0045 | $0.0025 | $0.0100 | $0.0100 |
| Verizon | $0.0040 | $0.0000 | $0.0065 | $0.0000 |
| U.S. Cellular | $0.0050 | $0.0000 | $0.0100 | $0.0000 |
| All other carriers | $0.0035 | $0.0000 | $0.0100 | $0.0000 |
| Carrier | SMS outbound | SMS inbound | MMS outbound | MMS inbound |
|---|---|---|---|---|
| AT&T | $0.0035 | $0.0035 | $0.0090 | $0.0090 |
| T-Mobile USA | $0.0045 | $0.0025 | $0.0100 | $0.0100 |
| Verizon | $0.0045 | $0.0000 | $0.0070 | $0.0000 |
| U.S. Cellular | $0.0045 | $0.0025 | $0.0100 | $0.0010 |
| All other carriers | $0.0035 | $0.0000 | $0.0100 | $0.0000 |
In practice, carrier fees add roughly $0.0035 to $0.0050 per outbound segment on top of the platform rate. That's why the all-in figure is the number to budget against, and why comparing providers on platform rate alone understates what you'll actually pay, anywhere, not just here. Rates are subject to change by the carriers. Download the complete rate card (PDF).
They're billed at exactly what the carriers charge.
No platform charge for incoming SMS on 10DLC numbers — the inbound carrier fees that do exist are printed in the table above instead of hidden in a footnote.
Volume is measured per calendar month and billed at the published band rates. High-volume plans run on a service agreement, so the rates you sign are the rates you're billed.
What would your volume cost?
Enter your monthly volume and see the estimated all-in cost — platform rates plus carrier pass-through fees. No sales call required.
Estimates use the published band rates plus a typical US carrier mix (carrier fees vary by carrier, roughly $0.0035–$0.0050 per outbound segment, and are passed through at cost). Outbound MMS bills at 3× the band rate plus MMS carrier fees. Your service agreement locks the exact rates.
TextSpot vs. Twilio at Volume
Twilio is the default name in high-volume SMS, so here is the honest comparison. Twilio's published pay-as-you-go rate for US messaging is $0.0083 per outbound segment (as of August 2026), with carrier fees passed through on top, number fees billed monthly, and volume discounts available only by contacting sales.
| TextSpot | Twilio | |
|---|---|---|
| Published platform rate (300K–1M/mo) | $0.0065 / segment | $0.0083 / segment |
| Published platform rate (5M+/mo) | $0.0046 / segment | Contact sales |
| Carrier fees | Passed through at cost, published | Passed through |
| Volume rates published? | Yes — on this page | No — negotiated |
| Sending software included | Yes — campaigns, inbox, scheduling, tracking | No — API only; you build and maintain the software |
| Developers required | No | Yes |
Twilio's rate buys an API. You still have to build, host, and maintain the sending software around it. TextSpot's published rates are lower at every published band — and the software is included.
If your team wants raw API access and has engineers to build on it, Twilio is a fine tool. If you want to send at volume without building software first, that is exactly what TextSpot is for.
What Is Enterprise SMS?
Enterprise SMS is high-volume, compliant, business-to-person text messaging, typically 300,000 or more message segments per month, sent through carrier-registered channels such as A2P 10DLC or verified toll-free numbers. It covers the alerts, reminders, two-factor codes, and marketing sends that need reliable delivery at a scale ordinary business texting tools aren't built for.
TextSpot runs both channel types, publishes its volume rates, and completes carrier registration in days, not weeks. Here's how it works, what it costs all-in, and how the numbers compare.
The same platform, built around what breaks at scale
10DLC or Toll-Free? Run the Math First
10DLC is business texting from a standard 10-digit local number, registered to your brand through carrier vetting. On the platform side, only outbound messages are billed — inbound is free — and throughput runs at the rate approved during carrier registration.
Toll-free is texting from a verified 8XX number. Both inbound and outbound segments are billed, at roughly double the 10DLC band rate, but it comes with verification and a consistent throughput floor of 3 segments per second.
The two number types bill differently, and at volume the difference is large. 10DLC usually wins for alerts, reminders, and marketing sends where replies are occasional.
Here's what that means in practice. An organization sending 1,000,000 outbound segments a month and receiving 300,000 replies pays $6,500 in platform rates on 10DLC, because 10DLC doesn't bill inbound segments.
The same traffic on toll-free is 1,300,000 billable segments and $15,300, about 2.4 times as much.
Most platforms never show you this math. TextSpot supports both number types and walks through the choice during onboarding, based on your mix of outbound and inbound traffic.

Frequently Asked Questions
What is enterprise SMS?
Enterprise SMS is high-volume, compliant, business-to-person text messaging, typically 300,000 or more message segments a month, sent through carrier-registered channels such as A2P 10DLC or verified toll-free numbers. It covers alerts, reminders, two-factor codes, and marketing at scale.
What counts as high-volume SMS sending?
High-volume SMS generally means 300,000 or more message segments per month. That's where TextSpot's published volume rates begin, starting at $0.0065 per segment on 10DLC and stepping down by band as monthly volume grows.
How much does enterprise SMS cost?
TextSpot's platform rates run $0.0046 to $0.0065 per message segment depending on monthly volume. Carrier pass-through fees add roughly $0.0035 to $0.0050 per outbound segment, so the all-in cost is about $0.008 to $0.012 per message.
How fast can you start sending at scale?
Carrier registration usually clears in 2 to 3 business days with TextSpot, against industry timelines commonly measured in weeks. Most organizations finish setup, import contacts, and send their first full-scale broadcast within one week.
Do I need 10DLC registration to send bulk SMS?
Yes. Any business sending SMS from a standard 10-digit US number must complete A2P 10DLC registration. TextSpot manages the process for a one-time $19 carrier registration fee, and approval usually clears within a few business days.
Do high-volume plans require a contract?
Yes. TextSpot's volume pricing runs on a service agreement, which locks the band rates on this page and keeps billing predictable at scale. Standard plans below 300,000 segments a month stay month to month with no contract.
Does TextSpot have an API for bulk SMS?
No. TextSpot doesn't offer a native API and isn't built as a developer platform. Integrations run through Zapier, which connects TextSpot to 7,000+ apps, so a CRM, calendar, or support system can trigger messages without code.
Are there hidden fees with bulk SMS pricing?
No. The volume bands are published, and carrier fees are passed through at cost with no markup. The only setup cost is a one-time $19 carrier registration fee. Incoming SMS on 10DLC numbers carries no platform charge.
Does TextSpot support sending outside the United States?
No. TextSpot is built for organizations sending to recipients in the United States, with rates set for US carrier networks. International sending isn't currently supported.
