SMSTunnel vs Twilio
A Twilio alternative for texts from your own phone and number
Checked November 2026 on the official websites. See the sources.
The short version
Twilio is an SMS API provider: your software sends texts from numbers you rent from Twilio, and you pay for each text. It's built for volume and reach, with short codes, toll-free numbers, sender names and more than 180 countries.
With SMSTunnel, your own Android phone sends the texts from its SIM, from your own number. There's a free plan, and paid plans from $9 a month, with no per-message fees; the texts go over your own mobile plan.
The prices aren't like for like: Twilio delivers every text over the carrier networks itself, and its price per text pays for that. With SMSTunnel your phone does the delivery, so each text is paid for by your mobile plan (often unlimited texts), not by SMSTunnel.
Choose SMSTunnel for texts a phone sends comfortably, from a number people already know. Choose Twilio for high volumes, US 10DLC numbers, short codes or numbers in many countries.

What you pay
Twilio, for texts to US numbers
- $0.0083 for each segment you send or receive (a segment holds up to 160 characters).
- The carrier's fee for each segment, passed on at cost: for example $0.0035 (AT&T), $0.0045 (T-Mobile) or $0.005 (Verizon) for each one you send.
- $1.15 a month for a local number, or $2.15 for a toll-free one.
- A2P 10DLC registration for a local number: a one-time brand fee ($4.50, or $46 for a standard brand), $15 to review each use case, and $1.50 to $10 a month for each one.
- $0.001 for each text that ends up failed.
Other countries have other prices: see Twilio's pricing page and pick the country.
SMSTunnel
- There's a free plan, and paid plans from $9 a month. The current prices and each plan's daily allowance are on the pricing page.
- Nothing per text and nothing per number from SMSTunnel.
- The texts go over your own mobile plan, so your carrier's SMS charges or allowance apply, including for texts to other countries.
When to choose Twilio instead
- You send high volumes: Twilio's registered 10DLC numbers send up to 225 segments a second, and short codes 100 a second by default. SMSTunnel sends what one phone can.
- You need a short code, a toll-free number or a sender name instead of a phone number.
- You text US customers as a business from a local number: Twilio registers your brand and use case for A2P 10DLC, which it requires for these texts.
- Delivery mustn't depend on a phone being on and online. Twilio's SLA covers the availability of its API (99.95% a month), and it sends status callbacks with delivery receipts.
- You need numbers in many countries without a SIM in each: Twilio sends to more than 180.
- You want MMS, WhatsApp or RCS from the same API, or a service that sends sign-in codes and checks them for you (Twilio Verify).
- You have no Android phone to keep on and online.
When SMSTunnel fits better
- People should see your own number, the one they already know, and reply to it.
- Your texts are ones a phone sends comfortably: order updates, booking reminders, sign-in codes, alerts to yourself and your team.
- You prefer a flat plan to paying per text, per number and per registration.
- You want to start today: install the app, sign in and create an API key. There's no number to rent.
- Your site or tool already has an SMSTunnel plugin or guide: WordPress, WooCommerce, Shopify, Odoo, n8n, Supabase Auth, Auth0, Clerk and more.
- You want end-to-end encryption: your software encrypts the text for your phone, and SMSTunnel can't read it.
How switching works
The call your software makes changes a little; the rest is setting up your phone.
- 1Install SMSTunnel from Google Play on the phone whose number should send the texts, and sign in.
- 2In your dashboard, open Apps → Add an app and copy the API key.
- 3Change the send call.
TobecomestoandBodybecomesmessage(both take up to 1,600 characters).FromorMessagingServiceSidgoes away: your phone's number is the sender, and with several phonesdeviceIdpicks one. The key goes in anX-API-Keyheader, and the body is JSON. - 4Instead of a
StatusCallback, pollGET /api/v1/sms/status/{messageId}. Instead of the incoming message webhook, turn on Sync received texts in the app and readGET /api/v1/sms/receivedwith a key allowed to read them. - 5Using a plugin with Twilio? Check SMSTunnel's integrations for the same tool first.

Questions people ask
Is SMSTunnel a Twilio alternative?
For texts a phone sends comfortably, yes: order updates, reminders, sign-in codes and alerts, from your own number, with no per-message fees. For high volumes, short codes, sender names, US 10DLC numbers or many countries, Twilio fits better, and you can use both.
How much does Twilio charge for a text in the US?
Twilio's US pricing page lists $0.0083 per segment sent or received, plus carrier fees that Twilio passes on, such as $0.0045 for each segment sent to T-Mobile customers. A US local number is $1.15 a month, and A2P 10DLC registration has one-time and monthly fees. Prices differ by country.
Do I need A2P 10DLC registration with SMSTunnel?
SMSTunnel registers no numbers: your phone sends the texts over your own mobile plan, from your own number, so your carrier's terms apply to them. If you text US customers at business volumes, a registered 10DLC number from a provider such as Twilio is the route US carriers set for that.
Does SMSTunnel check sign-in codes, like Twilio Verify?
No. Your software makes the code and checks it, and SMSTunnel sends the text, with a separate allowance for codes (50 a day on Free, no daily cap on paid plans). Twilio Verify sends the codes and checks them for you, for $0.05 per successful verification plus $0.0083 per text in the US.
Can my customers reply?
Yes, with both. With SMSTunnel, replies reach your phone like any text; turn on Sync received texts in the app to see them in your dashboard and read them through the API. With Twilio, replies reach your app through a webhook.
Can I keep using Twilio?
Yes. Texts sent through SMSTunnel come from the number of the SIM in your phone, and your Twilio numbers keep working. You can send everyday texts from your own number with SMSTunnel and keep Twilio for high volumes, short codes or other countries.

Responsible use
Send only texts people expect from you: sending business texts from a personal SIM can break some carriers' terms, so check your plan.
