Who wouldn’t fancy a free month?

Give a free month,
get a free month.

SMARTY is a new SIM-only mobile network that’s built to be simple and honest. Join us, refer-a-friend and you’ll both get a free month. Refer 12 friends and get a whole year free.

How to get your free months:

Order your SIM

Pick a plan below, order your SIM, and activate it when it arrives.

Invite friends

As soon as your SIM arrives you can invite as many friends as you like using your unique sharing link.

Get free months

For every friend that joins SMARTY using your sharing link you get a free month (they get one too).


At the end of the month, we take your unused data, turn it into money, and refund it off your next bill.
