Can I switch back to another type of prepaid card or to a subscription?
At any given moment you can switch to another type of prepaid card or to a subscription. Mind you: when you do, you’ll immediately pay the rate for your newly selected top-up/subscription.
You can easily switch from an Only Data rate plan to another prepaid card via your account on the website. Switch from your Only Data rate plan to a subscription can be done on this website page.
