textbee vs Plivo SMS API in 2026: Full Comparison

TL;DR

• Pick Plivo for carrier-grade volume, numbers in many countries, and compliance-heavy US A2P traffic. Pick textbee for transactional SMS from your own number on a flat plan, self-hostable, with an Android phone as the gateway.
• Plivo's US rate is $0.0077 per outbound SMS plus a carrier surcharge, plus $0.50/month per long code, plus mandatory 10DLC registration (pricing, checked September 2026).
• textbee's plans are flat: free (300 messages/month), Pro at $9.99/month (5,000 messages/month), Scale at $29.99/month (25,000 messages/month). No per-message fee.
• At 5,000 US messages a month, Plivo lands around $67-$72 with surcharges and a standard 10DLC campaign. textbee Pro is $9.99.
• Plivo wins on throughput and reach. textbee sends through one phone and one SIM, so it fits hundreds of messages a day, not thousands per minute.

Plivo is a CPaaS in the same category as Twilio and Vonage: rented numbers, per-message billing, carrier-direct routing. textbee is a different shape of tool. You install an Android app on a phone you already own, and your API calls go out through that phone's SIM from your own number. This post compares price, setup, deliverability, and compliance.

Quick comparison

What does Plivo cost compared to textbee?

Plivo bills per message, per number, and per 10DLC campaign. textbee bills a flat monthly subscription and does not meter messages. Below roughly 25,000 messages a month in the US, the flat plan wins by a wide margin once carrier surcharges and campaign fees are counted.

All Plivo numbers below come from its US SMS pricing page and 10DLC overview, checked September 2026:

• Outbound SMS, long code: $0.0077 per message
• Inbound SMS, long code: $0.0077 per message
• Long code rental: $0.50/month (toll-free is $1.00/month)
• Carrier surcharge, added on top: AT&T $0.0035/sms, T-Mobile $0.0045/sms
• 10DLC brand registration: $4.50 one-time
• 10DLC campaign vetting: $15 one-time
• 10DLC campaign, recurring: $10/month, or $1.50 for low-volume billed quarterly

textbee's plans come from the pricing page: free at 300 messages/month and 50/day, Pro at $9.99/month for 5,000 messages/month, Scale at $29.99/month for 25,000 messages/month.

Worked example 1: 500 messages a month

Plus $19.50 in one-time 10DLC fees on Plivo ($4.50 brand + $15 campaign vetting).

One honest edge case: if you qualify for Plivo's low-volume campaign at $1.50/month, those 500 messages land near $7.60 to $8.10 and Plivo beats textbee Pro. textbee's free tier covers 300 a month, so the crossover band is narrow.

Worked example 2: 5,000 messages a month

At 25,000 messages a month, the Plivo base rate alone is $192.50 before surcharges. textbee Scale is $29.99. For the same method applied to a CPaaS bill line by line, see what Twilio really costs per month.

How long does it take to send the first message?

textbee sends in about five minutes: install the app, pair the phone, paste an API key. Plivo needs an account, a purchased number, and 10DLC brand and campaign approval before US A2P traffic delivers. Its docs describe 10DLC approval in days, with carrier vetting on top.

Plivo send (docs, checked September 2026):

curl -i --user AUTH_ID:AUTH_TOKEN \
  -H "Content-Type: application/json" \
  -d '{"src": "+15550142", "dst": "+15550143", "text": "Hello from Plivo"}' \
  https://api.plivo.com/v1/Account/AUTH_ID/Message/

textbee send:

curl -X POST "https://api.textbee.dev/api/v1/gateway/send-sms" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"recipients": ["+15550143"], "message": "Hello from textbee"}'

Differences that matter when you port code:

• Plivo authenticates with HTTP Basic (auth id and auth token). textbee uses an x-api-key header.
• Plivo's endpoint embeds your account id in the path. textbee's endpoint is account-level and constant.
• Plivo takes one dst per call (multiple destinations are joined with <). textbee takes a recipients array and returns an smsBatchId for the whole batch.
• Plivo requires src, the number you rented. textbee has no sender field: messages go out from the SIM in the phone.

Deliverability, throughput and numbers

Plivo wins here and it is not close. Its SMS page claims 10K messages per second of throughput and 99.99% platform uptime (checked September 2026), with carrier-direct routes, short codes at $500/month, and toll-free numbers.

textbee's ceiling is physical. One Android phone sends messages one at a time through its SIM with a short pause between each. Consumer SIM fair-use policies typically sit around 200-500 messages a day, so a realistic textbee device handles hundreds to low thousands a day, not thousands a minute. You scale by adding devices and SIMs: Pro allows 5 active devices, Scale allows 15.

Practical read: 5,000 messages a month is about 167 a day, comfortable on one SIM. 50,000 a month is not a textbee workload, and you should use Plivo or another CPaaS for it.

The other axis is identity. Plivo gives you a rented long code recipients do not recognize, plus alphanumeric sender IDs where regulators allow them. textbee sends from your real mobile number, which people can save and reply to, and cannot change the sender ID at all.

Receiving SMS and webhooks

Both do two-way SMS. Plivo posts inbound messages to a message URL configured on the number, and delivery reports to a status callback URL. textbee pushes events to webhook endpoints registered on the account.

textbee events are MESSAGE_RECEIVED, MESSAGE_SENT, MESSAGE_DELIVERED, and MESSAGE_FAILED. Every payload is a flat JSON object with webhookEvent, smsId, message, deviceId, and an idempotencyKey for deduplicating retries, plus per-event fields such as sender and receivedAt. Each endpoint has its own signing secret for signature verification. Detail is in the webhooks docs.

To pull instead of push, the account-level history endpoint has cursor pagination:

curl -X GET "https://api.textbee.dev/api/v1/gateway/messages?direction=received&order=asc&limit=50" \
  -H "x-api-key: YOUR_API_KEY"

Follow meta.nextCursor until meta.hasMore is false, then resume from the last cursor on the next poll. See receiving SMS for every parameter.

One structural difference: inbound SMS costs $0.0077 per message on a Plivo US long code. Inbound on textbee arrives on your own SIM, covered by your phone plan.

Self-hosting and open source

Plivo is closed SaaS. There is no on-premise version, and your message data passes through Plivo's platform.

textbee is MIT-licensed. The Android app, the NestJS backend, and the Next.js dashboard are all at github.com/textbee/textbee, and the repository ships a docker-compose.yaml that runs MongoDB, Redis, the API, and the dashboard together. Message logs then stay on infrastructure you control, which decides it for some healthcare, legal, and finance teams. The catch: the app's backend URL is a build-time constant, so a fully self-hosted setup means building the Android app from source against your own domain and Firebase project. The self-hosting guide covers it.

Compliance: 10DLC and TCPA

Plivo requires 10DLC registration for US long code messaging. Its docs state plainly that messages from numbers not associated with a registered campaign will not be delivered, and that carriers can fine unregistered traffic. You register a brand ($4.50 one-time), submit a campaign ($15 vetting, $10/month recurring), and link your numbers. Optional brand vetting is $41.50 one-time and raises throughput.

textbee sends from a consumer or business SIM, which sits outside the A2P interconnect 10DLC governs, so there is no brand or campaign to register. That removes paperwork, not obligations. TCPA applies to both: prior express consent for marketing, honoring STOP, respecting quiet hours. Carrier fair-use terms also apply to your SIM, so bulk marketing blasts from a consumer plan get throttled. Our TCPA and opt-in checklist lists the consent records to keep.

When to choose Plivo

• You send tens of thousands of messages a month or need burst throughput.
• You need numbers in multiple countries without sourcing local SIMs.
• You need toll-free or short code sending.
• You need alphanumeric sender IDs or a branded sender.
• You need a platform uptime commitment in a contract.
• Your compliance team wants a registered A2P campaign on record.

When to choose textbee

• You send under about 25,000 messages a month, mostly transactional.
• You want customers to see and reply to your real number.
• You want a flat bill with no per-message meter and no surprise surcharges.
• You want to skip 10DLC registration entirely.
• You need to self-host so message data never leaves your infrastructure.
• You already have a spare Android phone and an active SIM.

Plenty of teams run both: textbee for domestic transactional traffic from a recognizable number, Plivo for international reach and volume. See also textbee vs Vonage, textbee vs Twilio, and the Twilio alternatives roundup.

Migrating from Plivo to textbee

Five steps for a send-only integration. Budget about 30 minutes.

1. Pair a device. Install the Android app on a phone with an active SIM, create an account, generate an API key. The phone needs power and a stable connection.
2. Swap the send call. Replace the Plivo client with a POST to https://api.textbee.dev/api/v1/gateway/send-sms, carrying an x-api-key header and a JSON body of {"recipients": [...], "message": "..."}. Drop src: there is no sender to set. Node and TypeScript projects can use @textbee/sdk instead.
3. Keep E.164 numbers. They already are, coming from Plivo. textbee rejects other formats.
4. Move inbound handling. Point it at a textbee webhook subscribed to MESSAGE_RECEIVED and verify the signature, or poll GET /api/v1/gateway/messages?direction=received.
5. Run both, then cut over. Keep the Plivo number live while you send test traffic through textbee to your own phone. Watch MESSAGE_DELIVERED and MESSAGE_FAILED for a week, then release the Plivo number and cancel the campaign.

The send swap in Node:

async function sendSms(to, message) {
  const res = await fetch('https://api.textbee.dev/api/v1/gateway/send-sms', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.TEXTBEE_API_KEY,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ recipients: [to], message }),
  });
  if (!res.ok) throw new Error(`SMS failed: ${await res.text()}`);
  return res.json();
}

Frequently asked questions

Is textbee cheaper than Plivo?

At most volumes, yes. At 5,000 US messages a month Plivo runs about $66.50 to $71.50 with surcharges, number rental, and a standard 10DLC campaign, against $9.99 flat on textbee Pro. The exception is very low volume on a low-volume campaign, where Plivo can land near $8. Above roughly 25,000 a month, Plivo's per-message economics win.

Does textbee work for international SMS like Plivo does?

Only as far as your SIM reaches. textbee sends through your phone's carrier, so international messages cost what your carrier charges and take the routes it uses. Plivo lists routing in 190+ countries with carrier-direct paths (checked September 2026). For multi-country campaigns, Plivo is the right choice.

Can I keep my Plivo number when I move to textbee?

No. A Plivo long code lives on Plivo's platform and cannot be attached to an Android SIM. Your sending number becomes your phone's number. Tell existing recipients before the switch, and keep the Plivo number active for a short overlap so replies to the old number are not lost.

Do I need 10DLC registration with textbee?

No. 10DLC governs A2P traffic on carrier interconnects, and textbee sends through a consumer or business SIM. You are still bound by TCPA consent and opt-out rules and by your carrier's fair-use policy. Less paperwork, not fewer obligations.
