SMS Overview

Send SMS through OneXtel — sending options, credits, and what differs between domestic and international delivery.

OneXtel SMS lets you send one-off messages, personalised sends, and bulk campaigns, with templates, sender IDs, and delivery reporting behind them. Send from the portal, from the API, or from a connected platform.

This guide covers SMS in the portal. Signing in, users, API keys, phonebook, blacklist, and account settings are shared across every channel and live under Platform.

Domestic and international

SMS is one product. What changes with destination is compliance, not how you use it — sending, campaigns, templates, and reports work the same either way.

	Domestic (India)	International
Registration	Entity ID, sender ID, and every template must be pre-registered under DLT	No DLT registration
Sender ID	Six characters, approved via DLT	Varies by destination country
Message content	Must match an approved template	Governed by destination-country rules
DND / opt-out filtering	Enforced by the operator, and by Scrub DND on your API key	Varies by country

Sending to Indian numbers without DLT registration fails at the operator, not at OneXtel — the message is accepted and then dropped. If you send to India at all, complete DLT registration first.

Destination rules outside India vary widely — sender ID format, permitted content, and time windows all differ by country. Check with your account manager before launching into a new market.

Sending options

Five categories are available under + New SMS:

Category	Use it to
Quick English SMS	Send text messages, schedule them, and import contacts from phonebooks or notepads
Quick Unicode / Multilingual SMS	Send in multiple languages, schedule, and import contacts
Dynamic SMS	Send messages with multiple variables, importing recipients and variable data from a spreadsheet
Multiple Dynamic SMS	Send using multiple templates from a single spreadsheet, for large-scale multi-template messaging
Campaign SMS	Run bulk campaigns with multiple variables and recipients imported from a spreadsheet

See Send SMS for the first four, and Campaigns for Campaign SMS and campaign management.

Credits

One credit equals one 160-character message. Longer messages are split into segments, and each segment consumes a credit — so a 300-character message costs two, not one.

Unicode and multilingual messages segment at a lower character count than plain English, so the same text costs more credits when sent in a non-Latin script. Factor this in when budgeting a multilingual campaign.

See Credits for allocation and top-ups.
