The Philippines is a major growing sms market but one which has many problems associated with message delivery. Carriers are implementing more and more spam filters to prevent A2P traffic reaching their network via international SS7 routes and large amount of messages on these cheaper routes are being blocked. Additionally, spam filters often return fake delivery receipts and do not discriminate between spam and legitimate traffic.
