How to Send Bulk SMS in Tanzania (Step by Step)

To send bulk SMS with DARSMS in Tanzania, create an account, choose an available sender, add verified contacts, check your message and credits, then send or schedule and review delivery. No coding is needed for dashboard campaigns. Custom sender approval may take additional time, so use the default sender for initial testing if appropriate.

Step 1: Create your account

Register a free DARSMS account with your business or organization details. New accounts start with a small bundle of free SMS credits so you can test straight away, and you top up with mobile money whenever you need more.

Step 2: Register a sender ID

Choose the default DARSMS sender for initial tests, or request a custom sender name and complete its payment and approval process. Select the approved sender when composing your campaign. Do not assume a pending name is ready to use.

Step 3: Add your contacts

Paste numbers or import the supported spreadsheet template. Review skipped entries and duplicates before sending. Validation checks number format, not whether a phone is active or belongs to the intended person. For marketing, use a list of customers who agreed to receive your promotions.

Step 4: Write and send

• Write a short message and check the final segment count; Unicode, links and personalisation can increase the credits used.
• Use personalisation tags to insert each recipient's name or other details.
• Send now, or schedule the campaign for a specific date and time.

Step 5: Track delivery

Review recipient-level statuses after sending. QUEUED means waiting for processing, SENT means submitted, and DELIVERED reflects a network report. FAILED or REJECTED needs investigation. A report is not proof of reading, and unresolved messages may need time before a final outcome appears.

Before you press send

• Preview a personalised row and check names, dates, amounts and missing fields.
• Use one language per recipient where possible and test the exact message on your own phone.
• Check available credits against recipient count and the longest rendered message.
• Confirm East Africa Time for scheduled sends and include an unsubscribe route for promotions.

What if a recipient does not receive the message?

Check the number, sender, scheduled time and status first. A valid number can still be unreachable, and delivery reports may be delayed. Record the message ID before asking support to investigate. Avoid resending the entire campaign when only a few recipients need review.
