Marchant Sim card is anInternational SIM card ( Voice+ Data) for over 200+ countries.
It’s very costly in our country as we are in a developing country. it takes 3rs/min. where Jio gives us free calling and internet. It’s network is not too good in india as it partners with Idea cellular.
Its’s internet charges is 2.5rs/mb .And we get 1gb /day from jio. So I think in this country this comapny can’t make any progress .
With othet telecom markets Its too much costly but if travel in foreign country often then You can choose it . Thank you
