How do I send my first SMS? +
Open the portal, make sure you have an approved sender ID and template, top up your wallet, then use the Send Bulk SMS composer — English, regional, personalised or campaign — and hit send.
How long does sender ID / template approval take? +
Approvals are handled through the portal's workflow. Once your DLT-registered sender ID and template are submitted, they're reviewed and marked approved, after which they're immediately usable.
Why was a message billed as more than one credit? +
Credits are counted by SMS segment. GSM-7 (plain English) fits 160 chars per segment; unicode (Hindi/regional/emoji) fits 70. Longer messages span multiple segments. Every send shows its encoding and credit count.
Do you have a REST API? +
Yes — Spark exposes a REST API to send SMS and check your balance programmatically, using an API key from your account. See API Collections inside the portal for endpoints and examples.
How do I download a GST invoice? +
Every order generates a GST tax invoice, downloadable from the Billing section of the portal. Add your billing GSTIN and address to your account so it appears on the invoice.
My messages aren't being delivered — what do I check? +
Confirm your wallet has balance, your sender ID and template are approved, and the recipient numbers are valid 10-digit Indian mobiles. If everything looks right, contact support with the message ID from your report.
