Common WhatsApp issues, limits and how to fix them

1) Account, number and payment setup

Wrong WABA or missing payment method

• If the wrong WhatsApp Business Account (WABA) is connected, or no valid payment method is added, sending can fail or stop without a clear error.

• How to fix: In WhatsApp Manager, check that:

  • The WABA you see is the same one that holds your connected number and templates.

  • A valid credit card/payment method is added under billing for that WABA.

Phone number already in use

• Your number might already be connected to another WhatsApp Business Account, Business Manager or provider, which prevents onboarding or shows “number already in use”.

• How to fix: Disconnect or migrate the number from any previous setup (old BSP, old Business Manager, or WhatsApp app) before connecting it in SAGA.

Business verification not completed

• If your Meta Business is not fully verified, Meta can block number approval or restrict messaging.

• How to fix: In Business Settings → Business info, make sure your business is Verified (correct documents, real company details, working website).

Number stuck in “Pending”

• Sometimes the number in WhatsApp Manager stays in Pending status even after setup, and messages will not send yet.

• What to expect: This is on Meta’s side; you must wait until the number shows as Connected. Only then will broadcasts start working.

Missing admin permissions in Meta

• If the person connecting WhatsApp does not have admin access to the correct Business Manager, connection and number approval can fail.

• How to fix: Ask the Business Manager owner to grant you full admin permissions, then repeat the connection flow.

Ad blockers or popup blockers

• Browser ad blockers or popup blockers can block the Meta popup used during the connection flow and cause the process to hang.

• How to fix: Temporarily disable ad/popup blockers while connecting WhatsApp.

2) Meta billing and limits

Meta billing and where to see costs

• Meta (WhatsApp) charges you directly for paid template messages, based on the type of message (e.g. marketing, utility, authentication).

• What to expect:

  • You add a payment method to your WABA in WhatsApp/Meta Business.

  • Meta bills that card directly for each paid message delivered.

  • You can track usage and spending in WhatsApp Manager → Insights:

New account sending limits

• New WhatsApp Business accounts usually start with low messaging limits (for example ~250 messages per day) and scale up as quality and volume improve.

• What to expect: At the beginning, large broadcasts may not fully send.

• How to fix: Start with smaller sends, keep quality high (low spam complaints, relevant content), and limits should increase over time.

Messaging limit / “Restricted” status

• Every number has a messaging limit tier. If you hit that limit, your number can become Restricted and you cannot start new conversations until some existing ones expire.

• How to fix:

  • Spread large campaigns over several days.

  • Monitor limits and status in WhatsApp Manager.

  • Improve quality (see below) to move to higher tiers.

3) 24‑hour service window

24‑hour rule for replying to customers

• When a customer messages your business, a 24‑hour service window opens.

• What to expect:

  • Within those 24 hours, you can reply normally with free‑form chat messages.

  • Each new message from the customer resets the 24‑hour window.

  • After 24 hours with no message from the customer, the window closes. You then must use an approved template to message them again, and that template is billed by Meta as a paid message.

How to avoid problems:

• Answer customer messages within 24 hours whenever possible.

• Use templates only when you need to re‑engage customers after the window has closed (e.g. reminders, follow‑ups).

4) Templates: approval and rejections

Templates rejected by Meta

• Templates can be rejected for:

  • Policy issues (spammy content, sensitive topics, prohibited products).

  • Wrong category (e.g. Marketing content submitted as Utility).

  • Wrong language selection vs the actual text.

• How to fix:

  • Keep content compliant with WhatsApp Business and Commerce Policies.

  • Choose the correct category and language when creating the template.

Formatting and variable errors

• Common problems:

  • Incorrect variable formatting (e.g. wrong {{1}} structure).

  • Using link shorteners (bit.ly, etc.), which Meta often dislikes.

  • Duplicating very similar templates instead of reusing approved ones.

• How to fix:

  • Use variables strictly as {{1}}, {{2}}, etc.

  • Avoid link shorteners; use full, clear URLs.

  • Reuse existing templates when possible.

5) Delivery, quality and account health

Messages not delivered to some contacts

• Part of a broadcast may not deliver because some numbers are invalid or not registered on WhatsApp.

• How to fix:

  • Clean your lists regularly.

  • Make sure phone numbers are correct and use the right country codes.

  • Only send to contacts you are confident are on WhatsApp.

Low quality rating / “Flagged” status

• If many people block or report your messages, your number can get a Low quality rating and may be Flagged. This can reduce your messaging limits or lead to restrictions.

• How to fix:

  • Send only relevant, expected, opt‑in messages.

  • Avoid sudden big cold campaigns.

  • Monitor quality indicators in WhatsApp Manager and pause campaigns if quality drops.

Account disabled by Meta

• Repeated or serious policy violations can lead Meta to disable your WhatsApp Business Account (WABA), stopping all sending and receiving.

• What to do:

  • Review Meta’s WhatsApp Business and Commerce Policies carefully.

  • If your account is disabled, follow the appeal instructions shown in WhatsApp Manager and adjust your use case/content before trying again.
