How do I change ( upgrade or downgrade ) my plan and keep the same number?

You cannot change your plan if you have a Vodafone Travel, O2 Travel, SMS Only, Bouygues, Orange or Data-Only Product. In these cases you will have to buy a new product.

However if you want to upgrade or downgrade your O2 or Vodafone Standard or Premium plan to a plan offering a different amount of data/calls you can change it by logging into your account on esim.net and navigating to Account > My Esim> Select eSIM> Change Plan. NOTE HOWEVER THAT WHEN YOU UPGRADE OR DOWNGRADE YOUR PLAN THE CHANGES WILL NOT TAKE PLACE UNTIL THE 1ST OF THE FOLLOWING MONTH.

You cannot change to the plan you already have, even if it is now advertised at a different price: the site shows "You are already subscribed to the selected plan". Your subscription keeps the price it was bought at; see Purchase options and recurring plans.

If you bought your plan on a corporate or partner account, your account menu shows Partner Portal instead of My eSIM. To change a plan on a corporate or partner account, email partners@esim.net from your account email address with your order number and the plan you want.

If you want to change from O2 to Vodafone ( or vice-versa ) you need to request a PAC code from us and use this PAC code when you purchase a new plan.
