The worst sim card I have buy till now . I thaught the 4g will be fast and amazing intenet surfing but my all thaught goes wrong and the sim has much issues that calling is big problem and second is slow . The name is 4g but the speed is like 2g . I wait for the sim for 1 week and I stand in line 2 3 hours than I got the sim card and it take 10 days to activate . And for 2gb it runs like 4g and after 4g it take like the 2g . Many person advice me that the sim is good but trust me it is too slow and believe the sim is good only for 2gb but after it takes slow . Thank you much for reading my review.
