Hello friends, I am Manish Goswami. My brother bought vivo smartphone for me. So I decided to buy a sim. My friend sumit tell me that aircel gives cheap offer. Then I bought Aircel 3g sim of Rs 15 only by showing aadhar card.It activated immediately. After that I recharged with a Internet pack of 49 and get 1 GB for one month. After that I came to my house and I saw it was showing no service. I left my phone for few minutes even then it didn’t worked. I went to roof then it started working with a with weak signal. In 3g connection it would not be load a single Google page. It is cheapest but what could you do with balance without being able to spend. In opinion if you are using a smartphone then you should use another mobile operator. If you buy then it is only waste of money.
