What the code gives
Code HONESTCODES is exclusive to HonestCodes and takes 15% off a first Yesim eSIM purchase, in the app or on the website. Choose a destination and plan, go to payment, type the code in the code box and press Apply. Then pay and scan the QR code to install the eSIM.
It is for first purchases only, so an existing Yesim customer does not get the 15%.
Picking a plan
Match the plan to the trip. Pay & Fly suits many-country itineraries, the Unlim Day Pass suits heavy use on short stays, and country plans such as Thailand from £1.26 a day suit one destination. Your phone must be eSIM-compatible and carrier-unlocked before you buy.
