Yes for 1800mhz band. I need good upload speed with the download speed so band 3 is required.
Band 3 don't have awful speeds. Airtel, Idea hold 10mhz+ bw in Haryana so their average speed with the good signal is always 20mbps+ dl & ul.
But I found that this seller also sells huwaei B525 which support (FDD 2600/2100/1900/1800/1700/1400/900/850/800/700MHz, TDD 2300/2500/2600MHz) That include all the indian 4g band but that model is sold out.
