Philippines: SMS Features and Restrictions


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.

Nexmo is pleased to announce that we are now using Adaptive Routing and a direct connection via Globe to all networks in the Philippines! This is a high-quality, stable route which will help to guarantee message delivery in the Philippines.



Starting from 5th October 2019 , All Public Telecommunications Entity’s (PTE) existing 7-digit telephone numbers belonging to AreaCode (AC)“2” will be migrated to 8-digit telephone numbers.

Corollary to the above announcement, National Telecommunications Commission (NTC) has assigned the following PTE Identifier, to be affixed at the beginning of the existing 7-digit telephone numbers. e;g

PTE Identifier PTE Ex.Existing No. Ex.New Number
8 PLDT Inc. +63 2 840 2359 +63 2 8840 2359
3 Bayan Telecommunications, Inc. +63 2 412 1212 +63 2 34121212
5 ETPI / TeleTech +63 2 300 1111 +63 2 5300 1111
7 Globe / Innove +63 2 730 1000 +63 2 7730 1000
