Pricing Deep-Dive

Sinch prices per message per destination, with volume-based tiers at scale — see Sinch’s official pricing page for current figures. SMSPM prices per SMS per carrier, no subscription — see our Prices page. The Android Gateway adds a flat €0.01 platform fee on top of your own SIM plan (often free/included).

Deliverability & Coverage — Honestly

Sinch’s scale and direct carrier connections make it one of the strongest options for global deliverability, particularly at high volume. SMSPM covers the same 190+ countries via commercial routes, plus the Android Gateway for markets where you hold a local SIM — messages ride the local network like a normal person-to-person SMS, avoiding grey-route filtering and arriving from a real, callable number.

This only helps where local SIM access exists — for markets with no local presence, Sinch’s direct-carrier scale is a genuine advantage over any smaller commercial gateway, SMSPM included.

API & Developer Experience

Sinch offers a broad, well-documented API and SDK set covering SMS, voice, and RCS.

curl -X POST "https://us.sms.api.sinch.com/xms/v1/$SERVICE_PLAN_ID/batches" \
  -H "Authorization: Bearer $API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"from":"SMSPM","to":["15551234567"],"body":"Hello from Sinch"}'

SMSPM’s API stays minimal — send, delivery status, and carrier routing control (including toggling Android Gateway per carrier).

curl -X POST "https://api.smspm.com/v1/send" \
  -H "Authorization: Bearer $SMSPM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"to": "+905551234567", "text": "Hello from SMSPM"}'

When to Choose Sinch Over SMSPM

• You need very large-scale global delivery backed by direct-carrier relationships
• You want multi-channel support (voice, RCS, email) from the same vendor
• You need enterprise SLAs and dedicated account management
• Your volume is high enough that Sinch’s tiered discounts beat flat per-carrier pricing

When to Choose SMSPM

• SMS is your core channel and you want transparent, flat per-carrier pricing
• You send meaningful volume to a country where you can get a local SIM — the Android Gateway cuts cost significantly vs aggregator rates while improving deliverability and sender trust
• You don’t need RCS/voice/email in the same platform
• You want automatic fallback to commercial routing if the phone gateway goes offline
