Global Call Forwarding VS Melrose Labs SMSC Simulator

Global Call Forwarding was launched in 2007 with the goal of becoming an exclusive outlet for toll free and local numbers. The parent company, United World Telecom (UWT), was founded in Florida, USA over twenty years ago in 1996 and originally operated as a callback service provider. With a growing customer portfolio and increased demand, UWT transitioned to being a call forwarding service provider over time and created Global Call Forwarding (GCF) in 2007 as a distinctive brand dedicated to providing international toll free and local numbers.

Melrose Labs operates SMSC simulators (aka SMPP server simulators) and Dedicated SMSC Simulators for use in the development and testing of SMS text messaging capabilities within applications. They simulate SMSCs (short message service centres) and SMPP SMS gateways, and simulate SMS message delivery. SMPP v3.3, SMPP v3.4 and SMPP v5 using TLS and non-TLS connections are supported.

Applications send SMS messages to mobiles by submitting messages to the SMSC Simulator service using SMPP. The SMSC simulators simulate the delivery of the messages, including the generation of delivery receipts back to the application. SMS messages from mobile numbers can also be submitted and delivered to the SMS application (see Simulate Inbound SMS to your Application).

The SMSC simulators enable you to send SMS messages from your application without messages being delivered to real mobile phones and therefore without any SMS delivery costs. Stress testing of your application can also be performed to show how your application behaves under load and various other scenarios tested before live operation and without affecting production SMSCs. The SMSC simulators can handle high rates of SMS and a large number of simultaneous connections from your application.
