Can I make multiple recharges of my DishNet number, in such case, how will I get benefits for all recharges?

Yes, you can make multiple recharge of the existing plan. All such recharges will be queued in your account in the same sequence in which they are recharged. These recharges will appear as “Upcoming Plan” under “My Plans” section of your “DishNet App”.
Similarly, as per your requirement, you can also make multiple recharges with different plans. All the recharges will be in queue and the recharge done first will be applied first and the other recharges will be queued in your account. The benefits of the recharged plan will come into effect only after the expiry of the validity of the current plan.
