A2P 10DLC for iPhone messaging.

A2P 10DLC is the US carrier system — AT&T, T-Mobile, Verizon. It governs SMS sent through the standard carrier network. iPhones receive both SMS (from non-iPhone senders or non-iMessage routes) and iMessage (Apple's own messaging protocol that travels over the internet). The pricing and compliance worlds are completely separate: SMS is A2P 10DLC; iMessage is not.

For brands whose audience skews iPhone (luxury retail, premium DTC, B2B SaaS, US coastal markets), paying for SMS infrastructure to reach iPhone users is paying twice. You eat the $48+ brand vetting, the $15-$17 per-campaign registration, the $1.50-$10/mo per-campaign monthly fees, the $50 T-Mobile activation, AND the $0.003-$0.005 per-message carrier surcharges — all to send a plain-text SMS through carriers that the iPhone could have received as a rich iMessage with lock-screen preview and read receipts at lower per-message cost.

The iMessage route bypasses every one of those fees. No brand vetting, no campaign registration, no monthly campaign fees, no carrier surcharges. Setup takes 1-3 days instead of 2-4 weeks. The message lands as a blue bubble with your real name and photo instead of as a generic SMS shortcode the recipient doesn't recognize. Open rates on iMessage average 98% versus ~85-90% for SMS to iPhone users.

For the Android portion of your audience, you can still run SMS via your existing provider. Many brands run a hybrid stack: iMessage for the iPhone half (no 10DLC), SMS for the Android half (with 10DLC). Or for iPhone-dominant audiences, iMessage-only with email or web push as the Android fallback. Tuco AI detects iMessage capability automatically per contact and can route accordingly.

Native to your iPhone audience

iMessage is what iPhone users use with each other. Blue bubble + your real name reads as personal — pattern interrupt vs SMS shortcodes.

No 10DLC, no per-message surcharges

Skip $143+ setup and $30-$50/mo carrier fees. iMessage has none of the carrier fee structure.

Lock-screen rendering, read receipts

iMessage lands on the lock screen with full preview. Read receipts give real engagement signal, not just delivery confirmation.

Auto-detection of iMessage capability

Tuco detects per contact whether the number can receive iMessage. Route iPhone users to iMessage, Android to SMS — or use iMessage-only for iPhone-dominant lists.

Do I need 10DLC if my audience is mostly on iPhone?

Yes if you're sending SMS (regardless of recipient device). The 10DLC system governs SMS routed through US carriers — the carrier infrastructure doesn't know or care whether the recipient is on iPhone or Android. If you switch to iMessage routing for your iPhone users, those messages bypass the carrier system and 10DLC doesn't apply.

How do I send to iPhones without going through carrier SMS?

Use iMessage routing instead. iMessage is Apple's own protocol that travels over the internet, not carrier infrastructure. Tuco AI sends via iMessage to iPhone users (detected automatically per contact). For Android recipients you still need SMS — most brands run a hybrid: iMessage for iPhone, SMS for Android.

Is iMessage delivery actually different from SMS?

Yes. iMessage lands as a blue bubble with your real name and photo, on the recipient's lock screen with full preview. Read receipts confirm engagement (if recipient enabled them). Open rates average 98% vs ~85-90% for SMS. iMessage messages can be longer (no 160-char segment limit) and render images inline.

What's the cost difference for an iPhone-heavy audience?

For a 10,000 messages/mo iPhone-dominant audience: SMS path costs $143+ setup plus ~$50-$100/mo carrier and campaign fees. iMessage path on Tuco AI starts at $59/mo with no setup, no carrier fees, no segment math. The savings compound at higher volume.

Can I use iMessage and SMS together?

Yes. Tuco detects iMessage capability per recipient and routes iPhone users to iMessage automatically. Android users continue to receive SMS via your existing provider. You can also use iMessage as the primary channel with SMS as fallback for delivery failures.
