You can remove the Golden eSIM at any time.
Note: first check if you have used up all your GB or Unlimited data bundles, as these will no longer work when removing the eSIM.
If you plan on travelling to the same country again in the near future, you can keep the Golden eSIM and use it again. Just purchase a new mobile internet bundle in the Golden eSIM app or web shop and use it on this eSIM.
