Roaming is a great way to stay connected and use your mobile plan overseas. Before you roam, you’ll need either a mobile plan that supports roaming or an international roaming plan add-on.

Before we look at roaming plans offered by popular mobile providers in Singapore, here are some popular mobile plans that include data roamingvoice and SMS roaming, or offer it via separate add-ons.

Types of roaming


There are three types of global roaming: data, SMS, and call roaming.

You'll typically find some allowance of data roaming in Singapore mobile plans, particularly to neighbouring countries like Malaysia. It's a great option if you regularly cross the border and need a roaming data allowance each month. 

In most cases, you may have to pay extra to make or receive calls or to send SMSes, if your provider even supports it. If you’re after SMS and call roaming, your best bet is to consider add-on packs or pay-as-you-go pricing. Some plans do allow for calls from international destinations, simply deducting your usage from your plan's IDD (International Direct Dial) allowance, while others (like premium-priced StarHub plans) include unlimited voice roaming.

Mobile providers that provide roaming calls and SMS


We track 17 mobile providers in our comparison engine. Most mobile providers in Singapore offer pay-as-you-go roaming rates for incoming and outgoing SMS and calls. These rates change based on the mobile provider (like StarHub, Circles.Life and M1) and selected countries. 

Unfortunately, not every provider offers both call and SMS roaming, especially as part of mobile plans. GOMO, for example, does not support calls while roaming. Many telcos offer a pay-as-you-go (PAYG) system, while others offer add-on roaming packs. You’ll also find some providers, like SIMBA, that bundle IDD and roaming VoLTE minutes, and some, like StarHub, that offer unlimited voice roaming on plans $38 and above. The only telcos we found that didn’t offer any voice or SMS roaming were GOMO, giga, Maxx, and Changi Mobile.

SuperRoam 12 SIM Only

  • 500GB data
  • Unlimited National Calls
  • 100 Messages
$12
Min. cost $12

For the best Indonesia roaming mobile plan, we recommend the SIMBA SuperRoam 12 SIM Only plan. For $12 per month, you’ll get unlimited local outgoing calls, as well as 600 international direct dial (IDD) minutes, which can be used to make calls while overseas.

This SIMBA mobile plan includes 500GB of data, bundled for use in Singapore, Malaysia, Indonesia, Hong Kong, and Thailand. You’ll also get 18GB of roaming data to Bangladesh, Malaysia, Hong Kong, Thailand, Taiwan, Vietnam, Indonesia, China and South Korea, as well as 8GB of data available for use in over 60 countries. 

Even though incoming SMSes while roaming are free, SIMBA doesn't support SMS roaming for outbound messages. Outside of the plan inclusions, SIMBA offers free calls over VoLTE—the only catch is that the minutes you use come out of your monthly IDD allowance. If you need more IDD minutes, expect to pay $5 for a Super IDD top-up pack. For more data, you're looking at a per-GB charge of $4.

SIMBA is a great place to start if you’re after roaming calls. as all SIMBA plans include free voice roaming over VoLTE.
