Dear valued members,
Smart system is partially good. We open our Inbound line so you can continue the business. Mainly for TOP-UP and DEPOSITS.
Unfortuantely Outbound line is not stable, which may cause no response / acknowledgement when you send information to 4483.
The best way to validate your top-up is via web tool.
Once we get more details from Smart, we will provide more update. Thank you for understanding.
