Bulk SMS software FAQ: questions people ask before buying

Yes, with no time limit. Every feature works without a key, and sending is capped at 25 SMS a day until you activate a licence.

From $29 a month, $79 a year or $199 once, on monthly, yearly or lifetime plans: 1 device on Starter, 3 on Business, 10 on Agency. Free updates, support and a 15-day money-back guarantee. Monthly and yearly licences are prepaid. Nothing renews or charges by itself: you renew from your account when you choose. There are no add-ons.

No. Ultra SMS sends through your own gateway account, and the gateway charges you per message segment at its own rates. We never resell SMS credit or add a per-message fee.

49 named gateways, grouped by region on the gateway setup page: global ones such as Twilio, Vonage, Plivo, Bird, Telnyx, Sinch, Amazon SNS, Infobip and ClickSend; Indian ones such as MSG91, Fast2SMS, Gupshup, 2Factor, Exotel, Kaleyra and SMSGatewayHub; and regional ones in Europe, the Middle East and Africa, Asia-Pacific and the Americas. Any gateway with an HTTP API works through the Custom HTTP option.

Yes. Each message can carry your DLT Entity ID, sender ID (header) and Template ID. You still register your entity, headers and templates yourself on an operator's DLT portal; the manual's India DLT chapter explains the steps.

An SMS holds 160 plain (GSM-7) characters. Longer messages are split into parts of 153 characters. A single emoji or curly quote switches the message to Unicode, where a part holds 70 characters, or 67 when split. Gateways charge per part, so the counter and the encoding fixer save you money.

Windows 10 and 11 and macOS 12 or later (Apple Silicon and Intel), plus an Android app (APK); the iOS app is coming to the App Store. One key covers the devices its tier allows, in any mix. Ultra SMS needs internet to send, to activate your key and for a licence check at least every 14 days.

1 device on Starter, 3 on Business, 10 on Agency, at a time. Deactivate it on one device to move it to another, up to 3 times a year.

Yes. Ultra SMS keeps a do-not-send list and skips those numbers in every campaign. Replies such as STOP arrive in your gateway account; import them or add them by hand, and many gateways also block those numbers on their side.

That depends on your gateway, your sender registration (DLT in India, 10DLC or toll-free verification in the USA), the destination network and your content. Ultra SMS gets the format and the fields right; nobody can promise delivery.

Yes. Numbers are stored in international format, and the cost estimate uses the rates you enter. Check that your gateway and sender ID are allowed in each country.

No. Text only people who agreed to hear from you. Our acceptable use policy forbids unsolicited bulk SMS, and the law in most countries does too.

It appears on this site straight after payment, Code Craft emails it to you, and it is always in My account. It starts with BS-. Open Ultra SMS, click Activate on the toolbar (or Help, then Activate / licence), and paste it.

Lifetime licences have no end date. For monthly and yearly licences we email a reminder before the end date. Renew from My account and the same key is extended, with any time you had left kept. If you do not renew, sending pauses; your lists and history stay on your computer.

You have 15 days from purchase to ask for a full refund, no questions asked. See the refund policy.
