This SIM is only sold in Singapore but roams to many different countries. I recommend stopping at Singapore airport (somehow) for the first leg of your journey to make life easier.
I know that sounds annoying, but I believe this one is valuable because this is a Singaporean SIM card that offers roaming rates identical to the normal Singaporean data rate which is pretty cheap across several countries.
- 1GB/ 3 days $5
- 1GB/ 7 days $7
- 1.2GB/30 days $10
- 2.4GB/30 days $15
- 3.6GB/30 days $20
This $15 SIM is very similar to our $30 SIM starter kits expect it includes $18 of credit with the SIM, which means you can instantly activate it with the 2.4GB plan or get 3GB over 9 days (see above)
You can use this data in:
- Singapore
- Australia
- Hong Kong
- Indonesia
- Malaysia
- Taiwan
- Thailand
- UK
- USA
I believe the best value for this SIM lies in:
- Wanting to do a SE Asia trip across several countries
- An $18 top-up seems to give you $20 of credit valid for 180 days, so you can use it for subsequent visits overseas.
- Being able to use the excess data back in Australia
- A real month for expiry
- 100GB of 3G data for use in Singapore in the first 3 days (dunno what you'd use it for tbh)
- Getting cheap data for the USA where comparable data is more expensive. As you can see $20 USD for 2GB, USA only, not including state tax or the price of the SIM which can be as high as $20 USD if you go to a T-Mobile store. $20 + $20 + 8% tax = $43.2 USD = $58.42 AUD.
- Being machine washable.
How to use
You need to have bought a valid domestic (Singaporean) data plan before and activate Happy Roam by (star)123(star)333#. Your APN needs to be switched to 'shppd'.

Other stuff:
- Roaming partners and additional information available in the clicky.
- For T-Mobile using travelers, the other option is to use the Tourist plan which is $30 SIM included for 2GB of data and unlimited domestic/int'l and 1000 min domestic talk texts for 3 weeks (21 days) so that $30 USD + state tax ~ $43.82 AUD or buy a $30 Walmart T-Mobile SIM for $34.82 USD excluding tax= $50.08 AUD which includes 5GB data, 100 min calls.
- Probably not possible to combine with the Changi Airport $40 voucher given that it excludes the retailers that sell the SIM, but hey you might get lucky and find it somewhere else? shrugs
Have you verified it can be registered for the first time outside of Singapore?
Also remember Singapore requires you to provide ID to get a Simcard. Are you sure you want complete strangers using a Telephone service thats registered against your name?
