[Official] SingTel SIM Only Plans

[gapboy]

Singtel hit by second disruption a day after eight-hour outage​

Homemaker Mrs Priscilla Wee, 56, said she had tried many times to turn her phone on and off. She even reloaded her Gomo e-SIM but to no avail.

Frustrated, she terminated her Gomo line on March 17 and opened a new account with Starhub. “The trust factor with Singtel is now gone,” said Mrs Wee.


So Mrs Wee is weak.

Reports of problems with Singtel’s services spike to over 500 on Downdetector​

3 days a charm

Some users are complaining SingTel down again now on Facebook Singtel page. Looks like there may still be issues, especially 5G.

My SingTel and Zym lines are both okay, with 5G SA connection.

Need to update the link. Your link somehow goes to another article about illegal PMD modification services.

Singtel never come out explain what's the issue.... no goodwill compensation also?

Let's wait a few days to see how it goes.

They may still in recovery stage and it seems they still have problems.

 

[xiaofan]

Just some guesses about the issues.

my household got 5 ST lines. 1st day all 5 down, 2nd day, two still down until late eveing then recover.
the 2 that was still down on 2nd day were 5G SA plans. It's a heng suay thing... I suspect their network slicing plus QOS efforts have made recovery more difficult and inconsistent. I don't have facts, just speculating.

that make some sense about network slicing. Singtel MVNO's aren't really affected, we get lowest priority and bandwidth

My guess is a bit different -- I am guessing the new 5G SA customers from SingTel Prepaid, Gomo and Zym/Zero1/VIVIFI/CMLink somehow stressed out the 5G Core Network.

3 days in a row? Prepare for IMDA love letter.

 

[darkarn]

My 5G and 4G lines all ok

I suspect this outage may be due to the upcoming shutdown of NSA networks

Update from Singtel Facebook

"We’re aware that some customers may be experiencing some momentary connectivity issues. The matter has been resolved.
Please call 1688 if you’re still facing issues."

at home now, seems like 5G SA connection very sluggish, loading of hwz is very slow...

connection drops to NSA too...

Hmm, no issues here. Pretty fast 5G speed.

How do you like RCS?

I don't feel the need to use RCS (or even the plain SMS) now that mostly I use WhatsApp and WeChat.

SINGAPORE - Singtel’s outage on March 16 affected about 600,000 customers and is due to a mechanical fault at one of its network facilities, the telco revealed on March 19.

Separately, about 2,000 customers experienced mobile connectivity problems on March 17 due to a software bug from a planned IT system upgrade, the telco told The Straits Times, revealing details for the first time since the back-to-back outages started.

“We know how important it is to stay connected and recognise the impact these incidents may have had on our customers. This should not have happened. We sincerely apologise,” said Singtel chief executive officer Ng Tian Chong.


“We are committed to learning from these events and working with our vendors to further enhance our network resilience and improve recovery times.”

For three days in a row, Singtel mobile customers faced problems connecting to its network. The eight-hour outage on March 16 caused customers to have “zero bars” of signals on their phones, and disrupted essential services in Singapore, including payments, ride-hailing and food delivery.

Explaining the event on March 16, Mr Ng said: “Though multiple redundancy measures were in place to support seamless service continuity, our situation required reconfiguration which took time to fully take effect.”

Explaining what happened on March 17, Mr Ng said the problem due to the software bug was not immediately apparent as it happened right after the March 16 disruption.

“Once identified, our teams took immediate action and connectivity was progressively restored, with full restoration completed by around 4pm on the same day,” he said.


On March 18, the telco said it carried out some network reconfigurations to further stabilise and optimise network performance following the two earlier disruptions. It encountered a brief spike in network traffic at around 5.30pm during the process, but the problem was resolved in about an hour.

The Infocomm Media Development Authority (IMDA) has commenced investigations into Singtel’s mobile network disruptions between March 16 and 18.

“IMDA takes these disruptions seriously and has commenced investigations and will take firm action against Singtel should any lapses be identified,” said the sector regulator on March 19.

Crisis communications experts who spoke to ST flagged a disconnect between Singtel’s earlier assurances and users’ actual experience on the ground.

On the evening of March 16, for instance, Singtel said that its service had been restored, but some customers continued to face connectivity issues into the next day.

“When customers are told that service has been restored but still can’t reconnect for hours, it creates a sense of confusion and erodes confidence,” said Dr Samer Elhajjar, senior lecturer from the department of marketing at National University of Singapore Business School.

Ms Christel Goh, founder of communications agency Grow Public Relations, pointed out thatthe only source of updates during the back-to-back outages were on the telco’s Facebook page. Users who faced issues were also directed to call the telco’s hotline at 1688, but many complained of long wait times.

“In a crisis, if customers cannot reach you, you must proactively reach them through frequent, real-time updates across multiple channels whether through social media, email or press statements,” said Ms Goh.

On March 18, some Singtel users started experiencing intermittent connectivity from noon. The telco put out a Facebook post at around 7.30pm, describing their problems as “momentary connectivity issues” that had since been resolved.

“This type of phrasing can sound dismissive when user reports are widespread and persistent,” Dr Elhajjar said.

He added: “Understating the problem can unintentionally damage trust. A more effective approach would have been to acknowledge the feedback earlier, clarify the extent of the issue, and outline what the technical teams were actively doing.”

Ms Goh acknowledged Singtel’s detailed technical updates on Facebook, including restoration confirmations and engineering activities. But she said that it would have been good to also acknowledge their frustrations as some livelihoods were affected.

Moving forward, the telco could offer more transparent explanations after the incident and more empathetic and proactive messaging to rebuild confidence, she suggested.

Mr Lars Voedisch, managing director at PRecious Communications, said that to rebuild public trust, Singtel could share what it has learnt from the outages and how it plans to change going forward.

The last Singtel mobile outage happened in November 2025, lasting more than six hours.

In October 2024, a Singtel fixed-line outage rendered hotlines for the Singapore Civil Defence Force and the police – along with those of hospitals and banks – unreachable. The telco was fined $1 million for the incident that affected about 500,000 users for more than four hours.

SINGAPORE: Singtel Singapore CEO Ng Tian Chong on Thursday (Mar 19) apologised for the company's recent outages, and said that the disruption that occurred on the first day - lasting more than nine hours - was due to a "mechanical fault".

 

[maumu]

after changing to a different phone, I can finally see Vo5G at the status bar... but sometimes it will change to VoLTE.

I also don't see it as VoWIFI anymore, even though I'm connected at home.

how come ah? seems like it can anyhow switch based on...?

1) From my Poco X7 Pro phone.

Under VoWiFi settings, there is a Network Preference option to "Prefer Mobile Networks" or "Prefer Wi-Fi".

I need to choose "Prefer Wi-Fi" to get VoWiFi working.

You may want to find similar settings for your phone.

2) As for VoNR, you need to have 5G SA connection, if not it will drop to VoLTE.

My Poco X7 Pro phone does not support VoNR under any Singapore networks though (I can enable the settings but it does nothing, still VoLTE).
