I have micromax canvas turbo A250 android smartphone and I can't access bsnl internet even I had all gprs settings with mannual settings. I got settings from web for micromax canvas 4 (b'cos canvas turbo is not in the list of bsnl devices) but the pin 1111 not working. I contacted custermer care many times but they cant solve this. plz tell me possible solutions or portal pin numbers.​

Do not worry about anything , if there is no problem in network of bsnl in your area then simply using BSNLNET apn will solve your problem.

I think its in :
Settings--> MORE --> Mobile Network --> Access points

Tell me what APNs you see there ?

Also make sure you have turned ON data connection.
