The SMSCarrier service from HSL Mobile® is a bulk SMS gateway comprising 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. Both SMPP and HTTP SMS APIs are provided.
Our Operations team monitor the service 24x7, ensuring that a highly reliable service is available at all times. The team is responsible for all sites through which customers connect with the service. Support for our customers is also provided by the Operations team, ensuring you are talking with people who are highly knowledgable on all technical aspects of the service.
Billing in GBP (default), USD or Euros takes place on the 1st of each calendar month. All prices for SMSCarrier accounts in GBP unless otherwise indicated. Invoices clearly show the traffic volume to each country on the invoice for each of your SMPP accounts.
