Text messages are usually delivered near to instantly or in seconds depending on your number of recipients. During peak hours, there could be a short delay. Please note that additional delays may occur if the recipient's phone is switched off or out of the coverage area. When this happens, a carrier will attempt to deliver your message for up to the validity period with a default duration of 48 hours.

7) What is the uploading file format that we support?
The upload file has to contain sender or recipient details or message text sorted in columns (at least one column must contain data). For example, when sending the same message with the same sender ID to multiple recipients, all you need to do is upload a file containing destination numbers sorted in a column. When sending different messages with different sender IDs to multiple recipients, you have to define these details by sorting them in columns. Each column represents a data group and each line represents a single piece of data and must contain appropriate details (e.g. the destination column must contain destination mobile numbers). Data must be delimited using one of the following: tab, comma, semicolon or hash. Supported formats: .txt, .csv, .xls.

If your target phone numbers have registered with PDPC not to receive SMS, please DO NOT SEND sms to your clients, unless you have an unambiguous consent with your clients to receive sms/text messages from your company.
Kindly note that GMT SMS DOES NOT auto filter or cleanse the DNC registered mobile phones numbers prior forwarding the messages to your recipients when you send smses from our platform. You are responsible to check your mobile listing with DNC registry (www.dnc.gov.sg) and cleanse them prior sending out the sms to the recipients.
13) How to prevent recipients from receiving SMS in the midnight if I blast large volume of SMS during the day?
In order to prevent your target recipients from receiving SMS in the midnight, kindly use the validity period (in hrs) feature. The default validity period is 48 hours. Example, if you plan to send your bulk SMS at 3pm and prevent your clients/recipients from receiving SMS after 11pm, then you should set the validity period to 8 hours. After the validity period is over, your delivery logs will show "not delivery (expired)" on messages that was not delivered and had expired.
