- AWS US 10DLC SMS lands at $0.02/message all-in ($0.01 base + $0.01 carrier fee) plus a registration stack: $4.50 company, $41.50 vetting, $10/month campaign, $1/month per number (AWS pricing page, 2026).
- AWS toll-free runs $0.01286/message after toll-free verification.
- SMSRoute US is $0.0125/message with an email-only signup and crypto billing - live in minutes, no AWS account, no 10DLC stack.
- Honest fork: deep AWS-integrated, US-domestic, high-volume -> AWS End User Messaging is a fine machine; fast start, mixed international, card-free -> The service.
What is AWS End User Messaging and what does US SMS really cost there?
AWS End User Messaging is the successor surface to Pinpoint and SNS SMS, with US domestic rates set by base plus carrier fees plus a registration stack, all listed on the AWS pricing page 2026.
The table shows the sticker prices. What it hides is the setup tax: company registration, campaign vetting, monthly fees, and a full AWS account that bills a card. That stack pays off only when US volume is high and steady enough that the lower per-message rate dominates. Below that threshold, or when you need international routes or want to avoid card billing entirely, the friction outweighs the rate advantage.
| Route | Base | Carrier fee | All-in |
|---|---|---|---|
| AWS 10DLC | $0.01 | $0.01 | $0.02 |
| AWS toll-free | $0.00581 | $0.00705 | $0.01286 |
| SMSRoute US | - | - | $0.0125 flat |
What's the true time-and-money cost before the first message?
AWS front-loads multi-day registration and fixed fees before any SMS ships, while the service gets a live route in minutes after email signup.
The decision rule is to treat that stack as capital you must amortize. Those AWS fixed costs only dilute under heavy domestic volume. Fund with crypto and the included test credits; for a pilot, international mix, or card-free operation the capital never spreads thin enough, so time-to-send decides the real bill.

Where does AWS genuinely win?
AWS wins on already-on-AWS infrastructure with IAM and CloudWatch integration, on US-domestic high volume at the $0.02 all-in rate with a properly registered 10DLC identity, and wherever enterprise compliance requires that full account footprint.
Once company registration, campaign vetting and monthly fees clear and the number is live, pure US OTP or notification volume dilutes those fixed costs fast. Per AWS End User Messaging pricing documentation for 2026 the all-in domestic sticker is $0.02 after base plus carrier fees. Teams already billing a card inside an AWS org and wiring sends through existing IAM roles keep the traffic there. That path wins over a separate provider when the workload stays domestic and compliance already points at AWS.
Where does SMSRoute win?
The service wins on setup speed without cards or AWS coupling, crypto payment rails, and international destination mixes.
You fund then pull an API key and traffic flows without waiting on vetting or campaign approvals or any card on file. Published per-destination rates let a US, UK, India blend price out before any volume commits and without surprise carrier add-ons. Real-time delivery reports land through DLR webhooks and the dashboard log so every message has a clear receipt. Alphanumeric sender IDs are available on request where destination routes support them, which covers most non-US OTP patterns cleanly.
What does a 10,000-message month cost on each?
For a pure US 10DLC month of 10,000 messages the AWS total sits above the the service flat rate once campaign and number fees layer on, and the visual breaks that arithmetic out by line.
The catch is that those fixed AWS charges only stop mattering after monthly volume climbs high enough. Choose the low fixed cost path until domestic traffic is large and steady enough that the committed AWS structure undercuts the route price.
AWS 10DLC: 10,000 x $0.02 = $200 + $10 campaign + $1 number + $4.50 + $41.50 one-time = $257
AWS toll-free: 10,000 x $0.01286 = $128.60 + verification lead time
SMSRoute: 10,000 x $0.0125 = $125 - email signup, crypto, live today

Is AWS SNS SMS the same as End User Messaging?
AWS consolidated SMS sending under End User Messaging. SNS-era SMS flows now point there for A2P features and registration. The SNS Publish API still accepts SMS destinations, but throughput, 10DLC campaigns, and spend limits are managed in the End User Messaging console per AWS documentation. Legacy SNS-only accounts without EUM registration hit carrier blocks on US traffic.
Can I use AWS SMS without 10DLC?
US domestic long-code A2P on AWS End User Messaging requires 10DLC registration. Verified toll-free and non-US destinations operate under their own regimes and do not use 10DLC. The service defaults to a smart shared sender pool and supports custom alphanumeric sender IDs on request where routes allow them.
Does AWS take crypto?
No. AWS does not accept crypto; SMS and End User Messaging charges bill to card or invoice only, so crypto billing is the the service lane where balances fund in BTC, ETH, USDT, XMR, LTC and SOL.
Which is cheaper for US OTP?
The service US OTP is $0.0125 flat versus AWS $0.02 all-in on 10DLC or $0.01286 toll-free plus fixed fees. Run your volume through both formulas; the artifact shows the 10k example. Built-in STOP-keyword handling and suppression lists cover opt-out compliance without a separate registration step.
