Indonesia: SMS Features and Restrictions

Sender ID:

Sender IDs might be replaced by an alpha value to ensure delivery.

Pre-registered Sender ID:
If you require assistance with setting your own pre-registered customised sender ID up Nexmo can help to pre-register for volumes exceeding 100k messages per month.
Please contact for more information.


There are no additional content restrictions beyond those in our Acceptable Use Policy

Keyword filtering:

Telkomsel (51010) / Axis (51008) /PT XL Axiata Tbk (51011):
Transactional traffic and messages containing certain keywords such as "Verify" / "PIN" / "Code" may be filtered. If you intend to send this type of traffic, please contact us at with information about your use-case and message template.
Nexmo has access to transactional routes able to bypass this restriction, and provide a pre-registered sender ID.
The SenderID needs to be in a Alphanumeric format (eg. abc123) of up to 11 characters max.


Unicode encoding is officially not supported by any of the networks in Indonesia, and we, therefore, suggest using GSM7 encoding. Extended characters such as brackets "【" and "】" are often problematic.

Concatenated messages:

Concatenated messages are not guaranteed to be delivered to all networks. We recommend that the messages be limited to one singular message, or break the messages into parts to ensure the best delivery. 

Other features/restrictions of note:

Delivery Receipts:
Delivery receipts are extremely unreliable across all networks in this country, some are missing completely, and therefore drawing conclusions based on DLR statuses will be inaccurate.

Ported numbers:

We do have reach to ported numbers on all networks. 

PT Pasifik Satelit Nusantara (51000):
Please aware that SMS are not supported towards this network.


Update - 26th February 2018

Starting 31st October, Indonesian government will require SIM card owners to register their number with a national ID. This requirement is immediate for new numbers, and will have a gradual impact on active subscribers until 28th February 2018, causing messages to fail towards unregistered numbers.

Partial SIM Card blocking (unable to send and make outgoing call/sms) will begin from 1st March 2018, till 31st March 2018. 

Full SIM Card blocking (unable to send/receive any call/sms/internet) will begin from 1st April 2018, till 15th April 2018. 

SIM Cards will be expired / retired from 16th April 2018

This registration is a government effort to prevent misuse of customer numbers, especially prepaid subscribers as the Government’s commitment in providing protection to consumers and for the interests of national single identity.

Delivery ratios towards Indonesia might be lower in the coming days. This will not be a route failure but a consequence of subscribers not registering their details.

Global SMS Numbers Features Overview

Virtual Numbers
Our virtual numbers can be used to receive inbound messages. However, outbound messages will unfortunately get the sender ID randomised, hence end users cannot reply back directly.
Additionally, please note they can only be used for person-to-person content, and neither application-to-person nor marketing content is allowed.
We recommend restricting usage to a maximum of 1k messages per virtual number and per day
