BSNL is one of the worst network. No service, no network. No signal. I bought new BSNL sim card but after 2 days only I decided to change the operator. whenever I call someone line get mixed vid other Caller. Most of the time no network in BSNL. Even in Delhi there is no network of BSNL. I was shocked to see that there was no network in Delhi. BSNL have very poor service. Whenever I call someone but call never get complete. After 15 days I changed my network again. Friend it’s my personal experience never buy BSNL . One of the worst network. You will cry later if u buy BSNL. go for other network like Airtel, idea, or vodaphone
