Invite a Friend to TOP SIM and Get 5GB of Free Data! 🎉

Got a friend who needs mobile data in Japan? Invite them to try TOP SIM eSIM and get rewarded with 5GB of free data!

With the TOP SIM referral campaign, both you and your friend can receive free data.

How it works

1. Open the TOP SIM app and share your invitation with a friend.
2. Your friend uses your invitation to purchase a TOP SIM eSIM.
3. Once your friend installs the eSIM and connects to the network, they receive 1GB of free data.
4. After your friend makes their first recharge, you receive 5GB of free data!

There is no limit to the number of friends you can invite, so the more friends who join and recharge, the more free data you can receive.

Who can invite friends?

To participate as an inviter, you need to have a TOP SIM and have completed at least one recharge.

Your friends must be new users who purchase an eSIM through your invitation to qualify for the campaign benefits.

Share, connect, and enjoy more data 📱

Whether your friends have just arrived in Japan or simply need an easy prepaid data option, TOP SIM eSIM lets them get connected without waiting for a physical SIM card.

Open the TOP SIM app, share your invitation, and start earning free data today!

Invite a friend → They get 1GB → They recharge → You get 5GB!
