SIM corner is amongst the best places to acquire SIM cards at a realistic price. If you should be travelling overseas, then SIM corner can offer cards which can be activated on arrival for various countries such as Japan. 

You need to look for the country you are visiting on the website (for example. Japan), you choose the SIM card duration that you would like, i.e. 8 or 30 days. 

Japan sim cards come with 6GB of 4G data on their 8 day plan or you can opt for a smaller 3GB data plan on a 30 day package which includes free social media apps such as Facebook, Whatsapp and Instagram usage.

If you wish to top up on, unfortunately most of their SIM cards will not offer this functionality. So if you think you are going to need more data, then chances are you should purchase multiple SIM cards. i.e. Buy 1 starting 1st and the second starting 10th.

How To Use Japan Prepaid Travel Sim?

Gone are the days of having to call up a call centre and activate your travel sim. Most sim cards are self activating once inserted into your phone. 

Simply turn off your phone. Remove the current sim card and replace with the travel sim card. You may need to break your sim card from the plastic to match the existing sim. Usually this is Standard, Micro or Nano sim. Newer phones are almost always nano sims.

Turn the phone on, enable data roaming. Restart the phone. Your device should connect to the new network. If it doesn't then you will need to manually enter APN settings.

Your sim card provider will provide instructions on how to do this. 

Make Sure Your Phone Is Unlocked

Some customers have issues trying to use a travel sim card because they bought a phone locked to another network. This is common in phones that are purchased under a 'leasing' agreement, where you don't actually own the phone. 

This is to stop you selling your phone to someone else and defaulting on your contract with your telecommunications provider. If you're unsure if your phone is locked then you should visit the retail store for your telco and ask, or call the help desk.

Most phones that are on a contract but you're paying to own the phone will not be locked and can be used with travel sims. In Australia it's rare for phones to be locked (with the exception of leasing). If in doubt, try a friends sim card from a different network in your phone before buying your travel sim card. If it works then you're good to go. 

It's unlikely you'll get a refund if your phone is locked and the sim doesn't work so ensure you're fully sure it will work before purchasing. Also it's nearly impossible to unlock newer phones while on the road so unlock it before leaving the country. 


All five recommendations above are good options when it comes to purchasing a prepaid travel sim card for Japan. After using all five options, we recommend checking out Simcorner for the best prices.

If you want unlimited data then you can do no wrong with choosing prepaidsims or even using Klook and picking up your sim card in the airport.
