Messaging, eSIM and calling, on our own infrastructure.
Bay Call Pty Ltd is a wholly Australian-owned telecommunications company and the holding company behind 160.com.au, eSIM4.com, Phone Card Choice and the Yabb App. We have served Australian businesses for more than twenty years.








Four business lines, one Australian team.
Each business has its own website and customer support. Bay Call provides the people, infrastructure and carrier relationships behind all of them.

160.com.au
Bulk, two-way and API messaging for Australian businesses, sent over our own SMS gateway with branded Sender IDs registered on the ACMA register.

eSIM4.com
Travel eSIMs in over 200 countries. Buy online, install on your phone before you fly and stay connected when you land.

Phone Card Choice and Yabb App
Low-cost international calling with prepaid phone cards, and the Yabb App for calls, SMS and eSIM data on iPhone and Android. Where Bay Call started.
Bay Call AI agents
Conversational automation for customer centres, by voice and by chat, built on the same carrier network as our messaging and calling services.
Own infrastructure.
We operate our own SMS gateway rather than reselling another provider’s platform, which gives us full control of routing, capacity and data. For voice, we run our own switching platform, interconnected directly with major Tier 1 carriers around the world.
