    M1 Sim-Only Plan

    [Ease of porting] Porting process was easy except that the porting date given was pretty long. It was 1 week later, probably due to Covid19 CB situation. [Billing] Value for money among the 3 main telcos. I ported over 4 lines from Singtel Combo plans. Despite having special rates in Singtel, I still save lots of $. They have promotions at $20 at times so do watch out for it and action. Please help to click "Helpful" if you find my review helpful 😀
  • [Update 1/7/2020] I thought I would give an update. I am still using M1 and have changed some of my other family members telco to M1 to take advantage of the multiple corporate discount. The transfer was seamless and I really like their customer service. Yes the signal might drop at some places, but I guess most telco have such events happening to them too. Overall, I am still a supporter of M1. [14/8/2019] I have been using this telco for quite a while and changed it at first due to the corporate discount that I have and it happened to be the most value for money. But came to realise that there are actually other good points about this telco that I would like to recommend. On a whole, I'm glad I changed to this telco because of the good customer service and reliability. The transfer from one telco to M1 was seamless and I had no cut off in my network which was great because it would have been troublesome to be without my phone line. Secondly, would like to praise the customer service for being fast and helpful. There were times in the past years that I have i) lost my sim card and ii) needed help with network overseas that I needed to call in to the customer service and they have been nothing short of helpful. Even overseas, they manage to waive my overseas call charges to them. I have since also changed my mum's line to be under my name to enjoy corporate discounts and even the transfer for that was smooth and seamless. I love love love the service given by M1. Oh, not to forget the free 3 M1 numbers I can call to for free - this is so my mum and I can talk all day long (or rather for me to hear her nag all day) Also, it's useful to have the M1 app on my phone because I can apply for data roaming on the app instantly and have it approved a few minutes later. It's good for me to have live tracking of my data usage, message usage and call minutes usage as well. It is useful for me to ration till the next billing cycle! The only qualm I can think of would probably be the weak signal when I'm in the train when passing by underground stations such as those on the Circle Line, but that is a small issue for me since I can just listen to music and not scroll through facebook/ instagram/ twitter.

    M1 Sim-Only Plan

    Always encounter dropped calls while exiting/entering MCE/KPE tunnel. Network speed used to be good, but its slower nowadays. Not the fastest, but the most usable/consistent as I would encounter more areas where I'm unable to access the Internet while on Singtel or Starhub.
  • Update 29/6/2020: -Signal: some places the signal is very weak -Mobile app: Android app is such a pain, especially the login part. It shows me the finger print login but after I input my finger, it just clears all the input and ask me to type again. I always ended up viewing my statement on website I have been using M1 plans for several years now. Currently under MySim plan. * 30 GB with additional 15GB data (45GB in total) * can add $12 to one more sim and share the data, phone, and SMS, which I think nice value when you can share it with your family member Overall, it has been a pleasant experience with M1 mobile plan
  • I have been with M1 for many years. So far the support from M1 is very good. Will continue to use M1 service provider
