AWS Pinpoint SMS is not being received in Indonesia

Hi Team, we are using AWS Pinpoint for sending OTPs to our users. When I try to send an SMS to a number in Indonesia, the SMS is not being received. I have event destinations enabled to a Cloudwatch log group where I can see the messageStatus is "SUCCESSFUL" and eventType is "TEXT_SUCCESSFUL".

{
    "eventType": "TEXT_SUCCESSFUL",
    "eventVersion": "1.0",
    "eventTimestamp": 1714041834221,
    "isFinal": true,
    "originationPhoneNumber": "NOTICE",
    "destinationPhoneNumber": "+62XXXXXXXXXXX",
    "isoCountryCode": "ID",
    "mcc": "510",
    "mnc": "10",
    "carrierName": "Telkomsel",
    "messageId": "68868af0-e093-47d0-9099-33bee759b3d7",
    "messageRequestTimestamp": 1714041827083,
    "messageEncoding": "GSM",
    "messageType": "TRANSACTIONAL",
    "messageStatus": "SUCCESSFUL",
    "messageStatusDescription": "Message has been accepted by phone carrier",
    "totalMessageParts": 1,
    "totalMessagePrice": 0.36308,
    "totalCarrierFee": 0
}

There is a post from 2 years ago where the OP was facing similar issues, it mentions the issue is with the carrier "Telkomsel" and the destination phone number I am trying to send the OTP to also is of the same carrier.

Please let me know what can be done to resolve this issue.
