What you should know about the Singapore eSIM card:

Can you imagine sitting on top of a skyscraper, having a drink at the bar while enjoying an incredible view and music? You can do this in Singapore! This city is full of nightlife and an incredible infrastructure that will let you make the best of your trip. The next day you can get up and get tanned on its beautiful beaches.

But before continuing to imagine yourself on this paradisiacal island sharing your experiences on social networks, you must know the main requirements to buy an eSIM in order to stay connected to the internet all time during your trip.

  • Check that your cellphone is compatible with an eSIM because it’s a relatively new technology, and some devices are incompatible.
  • Check that the operator or eSIM card provider supports your device. We know currently that the companies that provide the virtual SIM have preferred the iPhone XR or more recent versions.
  • You must have an email to register and receive your eSIM.
  • To activate your eSIM, you must have an internet connection since your eSIM profile will be downloaded from the operator’s servers. You can do this in Singapore or from a WiFi spot.
  • Some providers will ask you to install their app to download the eSIM.

If your smartphone is not compatible with eSIMs, we advise you to purchase a traditional physical SIM card from a mobile operator in Singapore.

Features of the eSIM to travel to Singapore

Local cellular operators offering eSIM in Singapore

If you plan to live in Singapore or are already a resident and want to change your traditional chip for an eSIM, there’s a company offering this service. However, remember that this company may ask you to comply with specific requirements according to their policies.

eSIM M1 Singapore.

Currently, M1 is the only phone operator in Singapore that offers eSIM to its local and tourist customers. Within its range of options, there are 4 prepaid plans to choose from: SIM Card or eSIM Card. The plans have costs from 12$ to 60$, the first for 14 days of use and the longest for 180 days of use. Of course, you can choose the one that best suits your stay and data consumption. We would like to point out that all plans have a monthly data limit, then you will have to pay a flat rate per Mb consumed.

Benefits of M1 eSIM in Singapore.

Once you choose a plan within the M1 eSIM options, you can access the benefits that any other M1 customer would have. M1 guarantees support for eSIMs on the latest generation phones and compatible devices. In addition to the benefits that come with an eSIM, you will also enjoy the following:

  • Calls and messages to local numbers in their basic $12 plans. Additionally international calls and roaming in more comprehensive $60 packages.

How to activate an M1 eSIM in Singapore.

First, you must select the prepaid plan that best suits you, and at the time of purchase at any of its stores, ask for an eSIM instead of a SIM Card. This has no additional cost. Then you can ask for help with the activation of customer service staff, visit the M1 website and read the activation guide for tourists, or if you have the experience, you can do the activation by yourself as you would do with any eSIM. It is important to remember that in the whole process, you will need an internet connection or wifi.

We must remember that if you are going to purchase the eSIM in a physical store, you will need a passport, Singapore IC, student pass, or any similar identification document. There are M1 stores in Singapore airports, in selected 7-eleven stores, and a whole list of M1 shops on their website to consult. As of today, purchasing the M1 eSIM Card through their web store is impossible.
