The SMSCarrier service from HSL Mobile® utilises our proven and advanced messaging infrastructure and provides reliable service, high availability and low delivery latency for customers connecting using the SMPP (Short Message Peer to Peer) API. The service is operated to provide higher reliability and quality of service than available from any individual mobile network's own wholesale SMS service.

Technical

Technical details of the service can be found in the Technical Details and Documentation sections including API details, message delivery architecture and infrastructure details.

Billing

Billing in GBP (default), USD or Euros takes place on the 1st of each calendar month.  All prices in GBP unless otherwise indicated. Invoices clearly show the traffic volume to each country on the invoice for each of your SMPP accounts.

Standard accounts: Customers are invoiced monthly in arrears. Standard credit terms are 14-days for at least the first 6-months of service.

Prepay accounts: Accounts must be pre-paid and credit is deducted as messages are submitted. Low credit notifications are sent to customers when credit drops below pre-defined levels.
