Just got a recharge done of 1gb 4G ,but it doesn't seem to be working. I'm getting 5-6 mbps in speed which isn't exactly 4g speeds(more than 3g though) but the signal still shows H on the status bar on the top of the phone. Is it some issue because my phone doesn't support the band ? I'm on Moto X 2nd gen.(Im from Kolkata)
