M1 Auto Roaming
1. Why does my mobile phone display "Emergency Calls Only" or "Forbidden" even when I have Autoroaming service?
  Your mobile phone displays this when the coverage is weak or if you are accessing another network instead of the one you subscribed to. You should move to an area that gives your phone a stronger signal. Use the arrow keys and menu button on your phone to access the right network. Before you leave for the country you intend to visit, check with the Autoroaming Countries list of network operators.
2. What charges do I have to bear if I make a local call in the autoroaming country which I am visiting?
  You will be charged the local airtime rate of the GSM operator and any roaming surcharge payable in your roaming destination.
3. What charges will I have to bear when I receive a call from Singapore while I am roaming in Hong Kong?
  You will have to bear the IDD charges from Singapore to Hong Kong, the local airtime rate of the respective operator in Hong Kong, and any payable value-added tax.
4. When I am roaming in Hong Kong, what number should a caller in Singapore have to dial to reach me?
  Your caller simply dials your mobile phone number as if you were in Singapore.
5. What number does my caller in Hong Kong have to dial to reach me when I am in Hong Kong?
  Your caller still has to make an international call, i.e. +65-968X-XXXX, to reach you on your mobile phone.
6. If I am roaming in Hong Kong, how do I make a local call?
  Just dial the party's local number.
7. Can I use SMS while roaming?
  You can still send text messages to another M1 customer while you are roaming provided the mobile phone of the recipient supports SMS.
1. Will I be notified if my short message storage on my SIM Card is full?
  Yes, most mobile phones will give an indication: a flashing envelope icon; or a beep tone and a text message. Please refer to the user manual of your mobile phone.

5. Do I need to change my current SIM to enjoy M1 Smart DualBand?
  No, it is not SIM dependent.
6. I have a PCN phone with me. Can I subscribe to M1 and be able to make calls using my PCN phone?
  No, M1 does not offer GSM 1800 plans since we operate a GSM 900 network. M1's Smart DualBand service is to provide you with the optimum choice of signals, to give you the best network performance.
7. Why does M1 have to complement its GSM 900 network with GSM 1800?
  As you know, our GSM service already covers 99.99% of Singapore. We are deploying GSM 1800, not for coverage, but as a means of providing more radio resources so that customers can continue to enjoy optimum network capacity. By doing so, we're proactively ensuring that there will be no congestion, or dropped calls, in high traffic areas. And with more data applications coming on stream, eg. WAP and GPRS, we're taking steps to ensure that you get the best network performance at all times.
8. Did M1 build its own GSM 1800 network or is it rented from SingTel or StarHub?
  The GSM 1800 network is entirely M1's. It is not rented from SingTel or StarHub.
9. If coverage is not good in an area, why doesn't M1 just add more transmitters (base stations) instead of using GSM 1800?
  This is not relevant as GSM 1800 is not used for coverage. We will build more GSM 900 base stations as the need arises for improved coverage in an area.
10. What will my phone LCD display when I am connected to M1's GSM 1800 network?
  You will still see "M1-GSM" on your phone. Our Smart DualBand network is a 2-in-1 network, hence it is seamless and transparent to a customer. That's why you won't see a change of network on your phone.
11. How extensive is M1 GSM 1800 coverage?
  It is especially extensive in high traffic areas like Shenton Way and Orchard Road.
