@Sunshine I have followed all the steps. There is 75% signal but still no internet. If I select IPv4 and IPv6 it showsas connected however no internet. Mobile phones works and some other sim cards...

It works with some operators like "ROBI". But it doesn't work with "GRAMEENPHONE" operator. I have tried many times. Please release update with fixes.
