Feature #1 – Custom built Push-To-Talk (PTT) service with high priority network traffic

GRIDTalk is a highly secured next generation PTT solution with a high priority dedicated service on Singapore’s largest 4G LTE network within a fully compatible ecosystem that is not offered by any PTT service provider in Singapore currently. 


It is also the only custom built PTT service in Singapore which takes into consideration the full end-to-end PTT performance. This ensures peace of mind in the business’s operations with advanced PTT functionality across the whole PTT ecosystem of handsets, operating systems, application and network from a single vendor.



Feature #2 – Cost management

Businesses can look forward to saving more and spending less by cutting out excess charges on GRIDTalk’s PTT service with Unlimited PTT Private Calls and Group Calls.


With data usage becoming more prevalent, it is also critical that the use of data in the workplace remains in check to prevent any unwarranted usage by the users. Different departments or functions within the organization may need to manage their budget within their own cost centres. Therefore, tariff cost control at the network level helps to prevent excess data consumption resulting in costly excess charges and bill shock to the organization.


However, GRIDTalk also offers customizable and affordable top-up options for more data allowance if required by the business. There are pocket-friendly add-ons available for all businesses to suit their different operating needs.


Handsets cost and monthly subscription are a significant expenditure for any new PTT requirements. With the flexibility to choose a longer contract period option for GRIDTalk, this outlay can also be potentially lowered.


Businesses can also enjoy a centralised service centre for all GRIDTalk-related enquiries and assistance. Reduce time and money in approaching separate vendors to solve different software/hardware/network related issues.



Feature #3 – Robust security (TLS & AES 256)

GRIDTalk is fully equipped with enhanced end-to-end security from SIM card to Network through AES 256 Encryption, SIM Auto-Login and Service Control Mechanisms at Network Side.

This means that all GRIDTalk services are hosted locally and securely in the Telco’s Data Centre with end-to-end AES256 encryption for voice and chat services.

This is unlike a personal mobile phone or other forms of OTT/PTT services whereby the Data Centre is not locally hosted, security of the PTT handset information containing sensitive information could potentially be compromised.

Thus, it is vital that a PTT handset is protected with additional security measures to avoid security breaches. Robust security encryption will help to mitigate any hacking attempts and prevent confidential information from landing in the wrong hands.


During an event when the handset gets misplaced, lost, or stolen,  a remote wipe of the information in the missing handset can also be performed. This is possible with the security permission of the administrator or the user with an optional pre-installed mobile device management application for added peace of mind.
