M1 to give 3 days of free services & bonus top-up to make up for service failure
Postpaid customers of M1 will get three days of free local mobile calls, SMS, MMS and data services from 10 February to 12 February.
Prepaid customers will enjoy a one-dollar bonus for every top-up of S$17 and above during February.
The telco is offering these to make up for the disruption in services.
It restored full 3G service in the affected areas on Thursday - more than 60 hours after it went down.
The service disruption started at 3am on Tuesday when a vendor was upgrading equipment at its network headquarters.
A power problem set off the gas suppression and water sprinkler systems, causing a mobile network switch to trip and services to fail.
