Important Notes
- TikTok & ChatGPT will work by changing APN to “esimnext” this changes the IP to Singapore (Android users: TikTok will only be accessible via web browser – the app will NOT work)
- Adding the eSIM outside the coverage country may result in a “failed activation,” which is normal. The eSIM will activate once you reach your destination.
- Turn off the eSIM line and do not turn on data roaming until you reach your destination.
- Check network coverage in your intended travel areas; Coverage issues are outside our control and we do not offer refunds.
- Fair Usage Policy – this eSIM includes 1.5GB of high-speed data per day. After reaching the limit, speeds are reduced to 1Mbps until midnight, when the max speed is restored.

Reviews
Bought three sims for Japan, all good.
Just turn on and go
Connect is always great!
fantastic customer service support. I was not very tech savvy but the support guided me through how to use an esim - so simple. Had no problems in Tokyo, easily activated on arrival and no issues with the data not workng. Very reliable and would use Travelkon again.
Really good, no problems whatsoever in Tokyo. Easy set up
Received the sim card on time and got connected straight away when touching down the ground. Easy and simple.
Fantastic sim.
Easy to activate and coverage unfaltering.
A handy travelling product
Easy to purchase, had some difficulty connecting but an email to customer support resolved the issue quickly. Since being connected the service has been very good
Leaving Sydney for Japan on the 12th of August
