GoHighLevel SMS is one of the most powerful features on the platform. Instant lead responses, automated follow-up sequences, missed call text-backs — all of it runs through SMS.

But if you are using GoHighLevel outside the US, you have probably run into problems. Messages not sending. Numbers not verifying. Automations firing without any message arriving on the other end.

This is one of the most common issues for Australian agencies and their clients. The good news is that it is fixable. Here is exactly how to get GoHighLevel SMS working correctly outside the US.

Why GoHighLevel SMS Behaves Differently Outside the US

GoHighLevel is built on Twilio for its SMS infrastructure. Twilio's SMS rules, number types, and carrier regulations vary significantly from country to country.

In the US, getting an SMS number up and running is straightforward. In Australia, the UK, Canada, and other markets, there are additional steps involving number types, carrier registration, and compliance requirements.

If you skip those steps or use the wrong number type, your messages either will not send or will be flagged as spam by local carriers. Understanding the difference between number types is the starting point.

Understanding SMS Number Types in GoHighLevel

GoHighLevel gives you access to three main number types through Twilio. Each behaves differently depending on your location and use case.

Local numbers are standard 10-digit numbers tied to a specific region or area code. In the US, these are widely used for both person-to-person and application-to-person messaging. Outside the US, local numbers often have restrictions on bulk or automated messaging.

Toll-free numbers start with 0800 or similar prefixes depending on the country. In the US and Canada, toll-free numbers can be verified for A2P (application-to-person) messaging, which is the type of messaging GoHighLevel automations use. In Australia, toll-free SMS is not commonly supported in the same way.

Long codes vs short codes is another distinction worth knowing. Long codes are standard phone numbers. Short codes are five or six digit numbers used for high-volume messaging. Short codes are country-specific and require a separate application process, but they offer the most reliable delivery for automated SMS in markets like Australia.

For most Australian GoHighLevel users, the recommended path is an Australian local number with proper A2P registration or a dedicated short code for higher volume needs.

How to Set Up an Australian SMS Number in GoHighLevel

The process starts inside your GoHighLevel sub-account.

Go to Settings, then Phone Numbers, and select Add Number. Choose the country as Australia and select a local number with an Australian area code. This gives you an Australian-looking number that local contacts are more likely to trust and respond to.

Once the number is added, you need to assign it to the sub-account and configure it as the default outbound number for SMS workflows. Go to Settings, then Business Profile, and make sure the correct number is set as the primary SMS number.

Test the number immediately by sending a manual SMS to a real Australian mobile. If the message arrives, your basic setup is working. If it does not, the issue is almost always registration or Twilio compliance.

A2P 10DLC and International Compliance

A2P stands for application-to-person messaging. It refers to automated messages sent from software rather than from a person typing on a phone.

In the US, A2P 10DLC registration is mandatory for sending automated SMS through platforms like GoHighLevel. Without it, carriers will filter or block your messages.

Outside the US, the terminology is different but the principle is the same. Australian carriers have their own rules around automated messaging, and Twilio enforces compliance on its end before messages go through.

If your GoHighLevel SMS automations are not delivering in Australia, the first thing to check is whether your number is correctly registered for A2P use. Inside GoHighLevel, go to Settings, then Phone Numbers, and look at the compliance status of your number. If it shows as unregistered or pending, that is your issue.

You will need to submit your business details, use case, and message templates through the LC Phone compliance section or directly through Twilio, depending on your GoHighLevel setup.

LC Phone vs Twilio: Which Should You Use in Australia?

GoHighLevel offers two options for SMS infrastructure. The first is LC Phone, which is GoHighLevel's own phone system built on top of Twilio. The second is a direct Twilio integration using your own Twilio account.

For most agencies and their clients in Australia, LC Phone is the simpler option. GoHighLevel manages the compliance layer on your behalf, and pricing is straightforward within the platform.

Direct Twilio integration gives you more control and can be useful if you have specific compliance requirements or need to manage multiple sub-accounts with different number configurations. However, it requires more technical setup and ongoing management.

If you are just getting started with GoHighLevel SMS in Australia, use LC Phone and work through the compliance steps inside the platform before considering a direct Twilio integration.

Common GoHighLevel SMS Issues Outside the US and How to Fix Them

Messages are sending but not arriving.
This is almost always a carrier filtering issue. Check your A2P compliance status first. If your number is registered but messages are still not arriving, review the content of your messages. Messages that look like spam, contain shortened URLs, or include certain words flagged by Australian carriers will be filtered silently.

The number field shows as verified but SMS still fails.
This can happen when the number is verified in GHL but the underlying Twilio registration is incomplete. Log into Twilio directly or check your LC Phone dashboard for any pending compliance actions.

Automations are triggering but no SMS is being sent.
Go to the workflow and check the action step for the SMS. Make sure the correct number is selected as the sender. If the field shows a US number, your Australian sub-account is using the wrong default number.

Contacts are receiving messages from a US number.
This means the sub-account default number has not been updated to the Australian number you added. Go to Settings, then Business Profile, and update the default SMS number.

Reply tracking is not working.
Two-way SMS reply tracking in GoHighLevel requires the number to support inbound SMS. Confirm this is enabled on your number inside the Phone Numbers settings.

Best Practices for GoHighLevel SMS in Australia

Keep your messages short. Australian mobile users are familiar with SMS and respond well to concise, clear messages. Aim for under 160 characters where possible to avoid messages splitting across multiple parts.

Always include an opt-out option in your first automated message. This is both a best practice and increasingly a compliance requirement in Australia under the Spam Act 2003.

Use your business name at the start of automated messages. Australian contacts are more likely to engage when they know who is sending the message rather than seeing an unknown number.

Test every automation on a real Australian mobile before going live with a client. What works in a US test environment does not always behave the same way once Australian carrier routing is involved.
