M1 refuses to let customers port out mobile number

I am trying to port out my mobile number from M1 to Zero1. Zero1 contacted me saying that M1 did not approve the port out in time, thus my porting process failed. i see many complained about M1 refusing to let users port out. Damn shameless! If M1's service is good, why would the customers want to port out? And IMDA has guideline that it is mandatory for service provider to process port out for customers when request is sent to them. When I contacted M1 via live chat, the agent claimed that they did not receive any request for my number to be ported out. Ya right! In this case, who do you think is lying, the losing service provider or the new service provider? I can do without this number. So, M1, even with this trick of yours, I am leaving you for good!

Thank you very much, Ms Tan.

My last weeks with M1

When I first signed up with M1, the network was great and all that but 20 years later, the quality dropped so is the customer service. The fact that I wasn’t informed of any additional payment needed after porting over to another telecom for that month after waiting for 2 weeks to see if I have to pay anything - radio silence from the company and I thought - that’s it. Months later, I discovered that the company has been chasing me for $$ for what? I have already port over to another telecom and paying that company directly and you didn’t instruct me anything when my line was successfully ported over.

What a shambles of a company! Not recommended at all.

Very poor customer service

Very poor customer service. The problem remains unsolved despite numerous calls. The worst teleco you can ever experience is M1.

Poor app experience and customer service

I was enticed to recontract my broadband through the app. There was an error in the installation date selected by the app that I discovered within 24 hours after receiving the email confirmation. The customer service i called refused to change the date without an additional charge of $65 even though the date is over a week in tge future and I wasn't asking for after office hours or weekends.

Works well locally, but not when roaming

I bought a $14 tourist SIM. The SIM card worked well in Singapore, but only worked periodically in Malaysia. I was unable to contact their support, as the SIM wasn't working. They offer no online support. I ended up talking to someone from the broadband team online, but they said they can't help and the only solution is to call the number (which I couldn't call). There was no obvious reason why it wasn't working, as it would randomly happen in different locations. The data speed was also much slower in Malaysia.

I would rate zero stars if possible.

Their AI help line is so bad I cannot ever get any help. and when I finally was able to talk to someone I had to go down to M1 shops to verify my account which in the first place I was directed to call the hotline when I went to M1 shop.

I have been a loyal M1 customer for…

I have been a loyal M1 customer for many years, but I am very disappointed with the recent decline in customer service and technical support, which has been unprofessional and irresponsible.

When I signed a contract online, the advertisement clearly showed free bundles included with the device. However, upon delivery, only the device was provided — none of the advertised items. When I called M1 to clarify, I was told these were “while stocks last.” If that is the case, it is both common sense and a matter of basic business ethics to update your website to indicate when such freebies are no longer available.

With the upcoming transition in company ownership, I sincerely hope M1 will take this opportunity to improve the quality of its customer support. Frankly, even AI solutions today often demonstrate more consistency and empathy than some of the agents I’ve recently dealt with. Customers deserve better.

Do Not Trust!!!!!

I activated roaming for a trip overseas last month. Before returning, I made sure to deactivate roaming via the M1 app — I clicked the orange “Deactivate” button, it turned grey, and I assumed that meant it was off. I showed this to my partner.
Apparently, that wasn’t enough — you’re supposed to receive an SMS confirmation that roaming has been deactivated. I never got that SMS, which means the roaming was still active without my knowledge.
The next month, I was shocked to see a full roaming charge of $68 on my bill. Before calling M1 customer service, I double‑checked the app again — the button was grey, showing “Deactivated.” I thought this confirmed it was just a glitch.
Unfortunately, my biggest mistake was not taking a screenshot — because during my call, the customer service rep “deactivated” it immediately, erasing any trace of the app’s error.
After a full week of back‑and‑forth, M1 insists the issue wasn't on their end, claiming their app has no issue and offering only a 50% refund — even though their faulty app was the cause.
This was not my fault, and yet I’m being penalized for their system’s failure. I do not recommend M1 — be very wary, always take screenshots, and never trust just the button status in the app.

Slow service and rude staff

My phone was lost recently but it was covered under FoneCarePlus.

Yet when I requested a replacement, customer service gave me a runaround. They were extremly rude, and left the chat during conversation and gave conflicting instructions.

I had to:

Reconnect with another agent

File police report for lost phone

Fill out a paper form for my phone's details like color of my phone (M1 had all the details already as its a contract phone)

Before M1 even thinks about sending a new phone.

Regret staying with them for so long…
All about money and only money…
Bought a phone and chose esim… accidentally delete everything in my old phone and was unable to activate the esim…
They charge another fee just to retrieve the email they sent me…
So many telcos around, M1 not special.
Treat us like trash…

Bad service,signed new contract cannot use 1 week

I was using M1 prepaid service since few years ago, not much prob. Recently signed a postpaid M1 contract. Staff promised will port my phone number to my new phone on that day mid night. But I was waiting for 1 day, got a message inform me not successfully. Called to service center, only work on weekday working hr. Wait untill weekday & called , service center said the old phone number was terminated......wtf! My original plan only want to get a phone with postpaid contract, at the end of number cannot use. Their Service & system not good, staff not supportive or knowledgeable to tell you what should do on next step to make the port transaction smoother....almost 1 week i cannot use my phone, seriously affect my work & my life.

Avoid

Avoid! This company has burned. Upgraded to eSim for which I was charged, then upgrade to 5G just t o get better connectivity. Have no mobile connection and couldn't receive or place calls for 2 days. 5 customer service chat, and 1 visit to store and still issues. Then telling me to wait 3 days so they can check their back end :D lol What world do they live in

Fraud

Fraud !
I purchase the monthly overseas (about 10gb) which is exhausted within 1 day !
The same phone, not surfing of movie, music, heavy usage and got charge $200++ for excess data usage.
I told them to review my past usage , there has never been once I exceed a 10gb per day , how can it be done for an overseas trip. Something is amiss.

They say data usage is different varies in different country ??? What logic!!

M1 is a clear fraud !

And their customer service says, all feedback MUST goes to their phone line , no on line feedback is available . Which means , I am stuck !!! It’s such an unfair channel !

It just telling u, I see the data , its running , its used so got charge !

Who the hell can used 10gb per day!!!!! When I am not even surfing the internet and it keep running and deducting .

It’s simply Becos I made the payment and they throw my case under the bus.

DO NOT EVER CHOOSE M1 !
They have the worst untrained customer service and system !
