The Infocomm Media Development Authority (IMDA) has advised a temporary suspension to our participation as a Participating Aggregator (PA) in Singapore’s SMS Sender ID Registry (SSIR). We are working closely with IMDA to resolve this matter and restore full functionality for whitelisted Sender ID delivery as soon as possible. The full list of PAs can be found here should you need assistance with whitelisted Sender ID delivery - https://www.sgnic.sg/smsregistry/list-of-participating-aggregators
