SMS relay

Our SMS relay product is designed to enable SMS capability on UK geographic (fixed line) numbering. The solution is supported by the UK MNOs and, through their cooperation, we have enabled nearly 90 million numbers for over 40 UK telecommunications operators.

How does it work?

The routing of mobile messaging traffic to landline networks is based on long-standing arrangements between the UK mobile network operators (MNOs) and the UK fixed line operators. We operate routing platforms at strategic traffic pinch points where we intercept and route the SMS messaging traffic. The SMS messaging service operates independently from voice traffic, so no changes to voice routing are required.

aql operates and delivers this service in two ways:

  • Enabled on aql's geographic numbers, which can be provisioned and provided to our channel partners via their customer relationship management or back office software via the aql numbering API
  • Carrier-to-carrier: aql can enable an operator's entire Ofcom number allocation and deliver the SMS to that carrier for onward routing
