Why Can't I Call a 1300 Number From My Mobile?

When a 1300 number will not connect from your mobile, the cause is almost always practical rather than mysterious: how the number was dialled, what your plan and coverage allow, or how the business has configured its number. Work through the four causes below in order — each takes seconds to rule out.

Cause 1: the number was dialled wrong

A 1300 number is exactly ten digits — 1300 plus six. From a mobile you dial it as printed, with no area code, no leading zero and no international prefix. Common mistakes include dropping a digit when copying from an ad, transposing digits, or adding an area code out of habit. If the phone reports "number invalid" or "call failed" instantly, count the digits first.

Cause 2: your phone, plan or coverage

If no 1300 number connects from your phone but ordinary calls work, check:

• Coverage. A call needs signal first; 1300 calls ride the same network as everything else.
• Plan restrictions. Some plans restrict or meter calls to 1300 numbers differently from standard calls — a pre-paid plan with exhausted credit is a common culprit.
• Barred premium or special ranges. Business and corporate plans sometimes restrict special number ranges by policy; your carrier can confirm and lift a bar.

What the call costs is a related but separate question: from a mobile, charges depend on your carrier and plan. Many plans include calls to 1300 numbers under the standard allowance; the "local call rate" promise is a fixed-line guarantee. If you are unsure, check with your provider.

Cause 3: the business''s number, not yours

If other 1300 numbers connect and one specific number never does, stop troubleshooting your phone. The fault sits with that business — its routing configuration, an unpaid account, or an answer point that rejects the call. Let it go to nothing, then reach the business through the contact number on its website. There is nothing you can dial differently that will fix a number that is misconfigured at its end.

Cause 4: business routing that turns callers away

A 1300 number follows the holder's rules: time-based routing can send after-hours calls to voicemail, overflow lists can exhaust themselves, and a mis-set rule can drop calls rather than divert them. If you reach a dead end, a menu loop or an unexpected voicemail during business hours, that is the business's setup working against its own callers. Calling back later often succeeds; telling the business its number is failing helps more than either of you realise.

The one-minute diagnostic

1. Re-dial the full 10 digits carefully, no area code.
2. Try a different 1300 number. If it connects, your phone is fine — the first business has the problem.
3. Try your first number from another phone. If it works there, your plan or handset is the variable.
4. Check signal and plan credit, then call your carrier if both look fine.
5. Fall back to the business''s website for an alternative contact path.

Callers who want the full dialling sequence, with costs, will find it in how to call a 1300 number, and the general fault-finding path — including failures from landlines — is in what to do when a 1300 number is not working. And if you are reading this because your own customers cannot get through, fix the routing — time-based rules, an overflow list and voicemail-to-email mean no caller hits a dead number. 1300 numbers covers the setup.
