The subscription to Multi SIM is independent of the main primary package subscribed by the user.
For example, if the main SIM is data-only SIM, all cloned SIMs will be data-only as well. If you have a New Postpaid plan on your main SIM, all minutes, SMSs, data packs etc. will also be available on cloned SIMs; postpaid customer can use only one SIM at a time to make or receive calls. All SIMs can use the data of the plan at the same time.
