I am using Aircel sim card from 4 years. The main problem with this sim is it’s network connection.
Internet connectivity is very poor in rural areas. Many times you will try to call but there will be no connection to call. Customer service of aircel is very bad as I tried to much and there was no one to response. Whenever I called to the customer care my call was on waiting for 2, 4-6, 10 minutes. Recharge packs are average you can afford it. But think, this modern eara in which 5G is coming who will ise 3g with very low downloading speed.
It is not good for rural areas.
Now, you should think according to your use.
