Singapore roaming prices, checked on 25 October 2026

Singapore operators sell roaming in passes: daily passports, 14-day packs and regional bundles. They are convenient, but the right pass depends on how many days you will be away. Below you'll find what each network charges, what that adds up to over a trip, and how to keep your number while using a travel eSIM for data.

The short answer

M1 charges SGD 2.95 a day to use your phone in its roaming destinations, so a week costs SGD 20.65. Some networks sell passes instead: M1's data Passport single destination monthly costs SGD 15. A prepaid travel eSIM is one payment for the whole trip, and you can keep your own number for calls and texts.

Why This Matters

Roaming charges are easy to miss until the bill arrives. If you know the daily price and where it applies before you fly, you can choose to roam, buy a pass or use a travel eSIM.

Two things change the price you pay. First, where you are going: networks group countries into lists, and each list has its own price. Second, when you joined: some networks charge customers who joined after a certain date more than older customers.

What a trip costs at those prices

A daily charge looks small until you multiply it by your trip. This table shows what each option costs for 3, 7 and 14 days if you use your phone every day. A pass that lasts longer than the trip is counted once.

To compare these totals with a Graba SIM plan for your destination, and choose how much data you need, open any network's page, for example M1 roaming costs.

Singapore networks that don't publish one price

Some networks set roaming prices by plan, so there is no single price to show. You can still see their roaming options and a link to their official page: StarHub, SIMBA Telecom. If we show no price, it means we could not confirm one, not that roaming is free.

How to avoid a roaming bill on a Singapore SIM

  1. Check the price for where you are going
    Open your network's roaming page and find the price for Japan. It can depend on your plan and when you joined.
  2. Set up a travel eSIM before you leave
    Buy it and install it at home on Wi-Fi. Leave it switched off until you land.
  3. Turn off data roaming on your usual SIM
    In your phone settings, switch Data Roaming off for your usual SIM. You can keep the SIM on for calls and texts.
  4. Use the eSIM for mobile data
    When you land, switch the eSIM on, choose it for mobile data and turn its Data Roaming on.

Turning data off doesn't stop every charge

Switching Data Roaming off stops your usual SIM using mobile data. Calls, texts and voicemail can still cost money. If you only need your number for security codes, see if your bank or apps can send them to an authenticator app instead.

Five days in Tokyo from Changi

Wei Ling is on M1 and flies to Tokyo for five days. M1 publishes a daily Data Passport and monthly regional passes. She checks which applies to Japan, then compares the total with a travel eSIM for the trip.

How a Singapore roaming charge starts

  1. 1 Your usual SIM is on abroad
  2. 2 You use your phone that day
  3. 3 Your network adds a daily charge
  4. 4 Use eSIM data instead
Your usual SIM triggers the daily charge. A travel eSIM gives you data on a separate, prepaid line.

Final Thoughts

The same week abroad can cost very different amounts depending on your Singapore network and plan. Check your network's page, then compare it with a travel eSIM that has the data you need.
