Most reviewers were unhappy with their experience overall. People frequently experienced frustrating network outages, unstable mobile data connections, and unexpected roaming charges that quickly added up to hefty bills without clear explanations. Consumers also struggled to get prompt, helpful assistance when contacting support agents via online chat or phone lines to resolve urgent connection and billing problems. Some people were satisfied with individual store staff members who provided friendly, polite assistance and professional guidance during in-person visits. Reviewers appreciated when employees showed genuine patience, listened carefully to concerns, and went out of their way to explain complex contract details or resolve ongoing inquiries smoothly.

I was billed 3 x $16 for reconnection fees and connection charges. Ended up paying over $100 for a paltry bill of $60. Total unscrupulous company who is out to made money. Deserve a zero star for that. Worst called their cso and no attempt for waive.
I bought a prepaid 1 month SIM card from the convenience store but wanted to extend it as my business trip was extended. I called Customer Service and was advised If I just top up before midnight the number would still be active and I could continue after the 1 month period. I topped up 16SGD and then they cut me off at midnight anyway. Pure criminal activities. Took the money and disconnected me anyway. The first time I called up I was given a number to call for my particular type of inquiry. I called the number the person gave me and....doesn't exist. Not even connected, I'm sure they thought that was funny. I honestly cannot believe how unashamedly crooked and corrupt that company is or how they have any customers at all. They really are the worst advertisement for Singapore.
Hi M1, I have been using your telco services since its inception, and I feel that the network coverage has been going from bad to worse in recent years. I can't even have a decent 1min call today as it kept dropping (I was in a restaurant at VivoCity btw). Also, the reception keeps going on and off when I'm travelling in the MRT, even when I'm not underground. This kind of service is really atrocious, even as one of the main telco players in SG. I know my feedback probably won't change anything but still, just wanted to warn the public of your waning standards.
M1 -Not even worth a star. Called and waited for 40mins. Chat feature also not working. No response and keep asking stupid questions. Some plans only offered to new lines. Existing customers pay more. Doesn’t make sense. Something’s missing in corporate level. One of the worst experiences.
M1 used to be good.. not any more. I live in Netherlands so kept a simple plan with M1. Upon arrival in Singapore.. called customer services for purchasing a package to topup data and call minuties.. got wrong info.. called again.. divert to website with bugs could not get anything done... round and round.. until I got to a physical shop to sign up a new plan.. been told the extra data charge will 'likely' be waived.. not the case.. can't get hold of any one.. call back not working... 150 extra dollars and a bunch of wasted time later.. I am leaving M1..
I recently had a tele-conversation with M1 CSO regarding a request for my oversea roaming charges. It was ignorance call charges incurred by my parent who was calling a relative in Malaysia. I had explained the issue and was told will need to seek management approval to our waiver/propose for discount to the bill request. The CSO who spoke with us, kindly acknowledge will definitely revert us the outcome within a week, however it been 2-3weeks gone by & we still did not hear any outcome. Finally, i call again and was told the request was unsuccessful. It was terribly disappointed as we had been using M1 services for more 2 decade and this is the service standard they response back to us.
On 18 Aug 24, visited M1 shop at Jurong Point and was served by the customer service Hui Boon. I would like to compliment Hui Boon for her patient, professional and explained in detail of the Flexi plan, which convinced me to sign up for the package. Once again, I thanks Hui Boon for her excellence services provided that make me change my mind to walk into other telco shops nearby. Best Regards Kelvin
I feel that m1 is positioned as a cheaper service, with product and customer service to match. Extremely sub-par customer service and no problem-solving abilities. Do not expect any level of empathy, initiative, or intellect in their customer service if comparing with the other Singapore telcos.
Horrendous termination process. Waited for an hour on the phone. Only to be asked to bring my elderly dad to the shop because of "protocol". Would never ever recommend. Easy to sign up, nightmare to cancel
I have worked for M1 for 4 years as a agent for their call center and till this day I still feel undervalued, Bosses are constantly micro managing and telling me what to do, things like waiver of fees and customer subscription all have to go through the approval of team leaders, total lack of empowerment and trust for employees, only come to this job if you need experience for future jobs!
Took a bespoke plan for 16.35 since august last year. Up till today I paid more that 3x than a years worth of subscription due to late fees, reconnection fees and failure to convert to this new plan. Company run by mindless, money hungry workers who are heartless and could not understand why e bill was late in e first instance. WILL never use M1 ever again.
Worst customer service. Now than l know that I can't change my plan through phone calls.
Customer service Manuel helped me a lot to retrieve PUK and guide me through patiently
my wifi is down, called the customer service and after about 2 minutes someone finally picks up, this person asks for the phone numbers related to the broadband and so I provided, he tells me that there is no such number with a broadband, turns out he typed in BOTH numbers wrongly into the system, and it is not like a single digit difference, it was the entire PHONE NUMBER, so okay sure, he then asked for the address, and I provided my 5 DIGIT postal code, and SOMEHOW HE MESSES IT UP AGAIN, not only that, he further messed up the 5 digit UNIT NUMBER?? then next he did not apologize and was rather rude, I provided the holder of the broadband's information, and he replied saying that I have not provided enough information even though I answered every single one of his questions clearly and precisely, then he further accuses us of not paying the wifi bill? is this really the standard for working at M1? is this what M1 is?
Extremely bad customer service that cant even help with app login. I’m extremely surprised by them. I have 1 issue with my app and, everyday a diff person reply me 1 msg and then disappears when i reply explaining that isn't the issue im facing… then no reply and this repeats over and over. This is worst than talking to the wall. This is the very last time i will be their customer for sure
Wow, I just got off the most bizarre phone call with M1's customer service. It's really difficult to give a dying business a hand when they can't even take customer complaints seriously. So back in 2023, I activated my M1 data passport when I was back in the United Kingdom for holiday. But I was unable to maximise the usage of the network service due to the poor network connectivity during the entirety of my trip. When I came back to Singapore, I filed a formal complaint at the M1 shop when it was still located at Peranakan Place, just opposite of Orchard Gateway, with one of the sales representatives there at that time, where it was recommended that I had my network fully upgraded to 5G (bear in mind, data passport only allows you to use up to 4G networks, and in the United Kingdom, M1's partner network is Vodafone UK). Still, out of graciousness, and having been a long-term customer of the telecommunications company since my secondary school days, I upgraded my network, clinging on to a belief that M1 would start working on building/upgrading their partner networks. Fast forward to this year, I had activated my M1 data passport, once again back in the United Kingdom, only to experience the same network failure YET AGAIN! Now, I could spend my entire trip, making a fuss, with incompetent M1 customer service, or I could make the trip more pleasant for my family by suppressing my anger and getting a local SIM card and utilising the data network. And so, I did. I purchased a SIM card from EE, whom I found out, is a partner network of Singtel in the United Kingdom, coincidentally. Upon my return from the United Kingdom, I proceeded to make a phone call to M1's customer service earlier this afternoon, where I took the time to explain to them my displeasure of having yet another episode of poor network connection during my month-long trip. The conversation as follows, CS Rep: "Sir, we are unable to do anything right now as you are back in Singapore and there are no issues with your connection. However, if you do experience it again please let us know at that point of time so that we can resolve it." Me: "Would that be all that you can do then? I take it that after being a long-term customer, surely your team will be able to come up with some form of compensation for yet another failure, let's add that it's a REPEATED failure. Or would you rather I took a flight back to the United Kingdom so that I can PROVE to you that I couldn't get a network connection and I couldn't even call out?" CS Rep: "Sir, I was not implying that. All I'm saying is that the next time it happens to get back to us immediately so that we can help to resolve it on the spot." Me: "I COULDN'T EVEN CALL OUT WHEN I WAS THERE. Which part of that did you not understand? And to simplify it for you, unhappy customer, filing a repeated complaint, and you mean to tell me that you are unable to compensate a very unahappy customer who, by the way, will be refusing to pay for the upcoming bill because it makes no sense when he did not even get to enjoy the service at all, and you are demonstrating how utterly useless M1 is that I had to rely on EE, who is a partner of Singtel, in the United Kingdom. Are you implying that I should turn towards your competitors for better network solutions?" CS Rep: "... Sir, I won't be able to stop you from doing so..." Me: "Ok, sure, thanks for confirming with me that I shouldn't have placed such high hopes on your company since last year. And thanks, for confirming with me that M1 is willing to let its loyal and faithful customers walk over to their competitors without even fighting for us, when we have always fought for the company by believeing in your brand. Thanks for making customers like us feel stupid." CS Rep: "Thanks for your time and continuous support all these time." Still at a loss for words with, by far, my greatest disappointment in a local brand, M1, and to think I still gave you lot a chance to redeem yourselves. What a waste of time and money...
Been calling them for a new sign up broadband, appointment having problem. Calling them for 5 time problem cannot be solve, promise to call back everytime but waited and waited no call back. Most frustrated part is calling them need to waste alot of time waiting, problem is they can't solve problem. Call them the last time(5) asking them why alway give empty promise their answer was tried to call but cannot get through, sound very funny my phone is working fine others can call in only when comes to M1 they can't get through. Asking them to cancel my order, they say I have receive the contract so cannot cancel but what the hell is I never get anything from them. Find it really very bad service for problem solving, keep telling me check with the backend but after few day still asking me the same thing which i think they are not logging the problem to their system that why they keep asking the same question. DISAPPOINTED
I was attended by a staff by the name of Kelvin or Kevin Wong knowledgeable and helpful with the product analysis. I am also pleased with after service support with another staff from Shen in updating my old phone details to the new phone in an hour. Thank you both
Call the service centre since May 19, 2024 and each call I made waited for at least 30 min to get thro the customer service officer, but since then the issue has not been resolved and the technical issue was mainly due to their system glitch and never get a call back from them to update the issue. Worst Telco in sg
