Hi @cyril_56880 and welcome to 3Community. I'm glad you reached out, data roaming in Singapore is available but it can be expensive without a roaming add on. If you click here you'll see the charges applicable for roaming in Singapore.
Are you a Bill Pay customer or a Business customer? If you are a Bill Pay customer, I recommend that you log in to your My3 and go to Explore Add-ons to see what data roaming add-ons are available and suitable for use in Singapore.
However, if you’re a Business customer, I recommend reaching out to your account manager or clicking here to chat with our Business Messaging team. They'll be happy to help you select the best add-on.
