Other Queries

Information provided on the Explorer SIM packs here are for your ease of reference only and may be subject to amendments by the operator without any prior notice. If you have any other queries not answered below, please log-on to the Explorer SIM web-site or call their Customer Service directly.

What's the difference between using the Explorer SIM and using my normal Singapore SIM card when I am overseas?

Yes, it is convenient to use your Singapore SIM card when you are overseas like you do when you are in Singapore, BUT you will be incurring EXPENSIVE roaming charges for all your usage (i.e. for all incoming / outgoing calls, outgoing SMS and data usage).

Instead, opt to use the Explorer SIM when you are overseas,  which lets you make calls / SMS / data at very economical rates (click here to find out the call rates for your destination). In addition, you will be able to receive incoming calls for free in over 70 destinations and receive free incoming SMS all around the world.  What's more, to complete the solution, you can use our Link Service to forward your Singapore calls to your Explorer SIM, so you won't miss any of your calls.

What phone number will I get with the Explorer SIM?

You get a +44 (U.K.) mobile phone number. What’s more, you have the option to also simultaneously add a +1 (U.S.A.) number onto the same Explorer SIM.

Is the Explorer SIM compatible with my phone?

If you normally use your Singapore number in your phone, you will be able to use the Explorer SIM in it. Otherwise, if you've purchased your phone outside of Singapore, please ensure that your phone is not SIM-locked, else you will not be able to use any other SIM cards in your card other than that issue by your original telco operator.

What is the size of the SIM card in the International SIM pack?

The International SIM card comes as a tri-sized SIM (regular / micro /nano) SIM card.

Do I need to register the Explorer SIM before using it?

You will NOT need to register your Explorer SIM. It will be automatically activated when you use the SIM for the first time OUTSIDE of Singapore.

Is the Explorer SIM easy to use?

The Explorer SIM is relatively easy to use. Each pack comes with its one starter manual. WHEN YOU ARE OVERSEAS, here’s all you need to do:
(1) Slot your SIM card into your phone and turn it on. Key in your PIN number.
(2) Wait (up to 5 minutes) to detect a network.
You’re now all set to make calls / SMS / data.

I've slotted the Explorer SIM into my phone but I’m not able to make / receive calls? Is something wrong? (I am currently in Singapore)

If you're still in Singapore, you will not be able to use the Explorer SIM. It can only be activated when you make your first call outside of Singapore.

I tried to make an outgoing call with the Explorer SIM but the line just disconnects. Is something wrong?

This is normal! To make a call with the Explorer SIM, please also dial “+” followed by full international dialing format of the number (i.e. with the country code and the phone number). When you press dial, your call will immediately cut off and the system will call you back within 60 seconds. Just answer the call to connect.

How do I receive calls with the Explorer SIM?

To receive a call, simply answer it as per normal.

How much prepaid credit is in the Explorer SIM?

The Explorer SIM we offer comes preloaded with USD$10 credit.

How do I top-up the Explorer SIM?

You can purchase top-up for the Explorer SIM online at or by calling the 24/7 Customer Service at +1-888-5138804.

Will I be able to surf the web / download e-mails?

Yes, you will be able to surf the web / download e-mails via GPRS / 3G at the prevailing rates of the Explorer SIM. Opt to sign-up for a data bundle to reduce data charges substantially (click here to log-onto the operator's web-site for more details).
