Guys, this is my personal experience.
When iam on a trip and in some forest then iam alla alone and unable to contact anyone, iam single on my bike and after crossing that forest also no signals. And that trip is the bad experience as I didn’t get any signals for my docomo sim and iam unable to open google maps. And even unable to contact anyone to know the directions.
This happens only when I go for trips or long drives. This works fine in city.
And another bad thing in its internet speed. It disturb my life literally. Suddenly net stops and turn on again automatically. I don’t know why that happens.
And on calls there is no clarity. Unable to hear voice clearly.
So guys when you use it in vity its ok but when you use it in some remote areas it does not work good as you expected.
