Is it working if my phone is sim locked ?

Do you ship abroad ?
Yes, we ship to France, Australia, Canada, UK, USA et US Military bases.
What sim sizes are available ?
Our Japan sim cards are multi-sizes. Standard, Micro and Nano all in ONE.
Can I pay with foreign credit cards ?
Of course ! We are proud users of Stripe, so your card is accepted and your information always safe.
Should I return the product ?
No, prepaid sim cards do not have to be returned
What is an APN ?
APN (Access Point Name) is a special profile set up for telecommunication providers. APN are most of the time pre-set to your phone by your wireless service provider. You need to change these values to ours in order to get smashed by data !
