2G network world over are getting switched off with move to 4G/3G networks. In India we are far off from that. Still 2G networks are lot more congested here because majority of phone sold are feature phone with 2G only support. Majority of customers use phone for voice only. Though this trend is changing with recent 4G boom however we’re still far from it.

3G network is far less congested due lesser no of users on 3G & technically also it got more capacity than 2G network using same frequency.

Also in most users in India uses dual sim phones which are mostly 4G+2G. However recent latest chipsets got capacity for 4G+3G to be on simultaneously. Here one 4G sim can be used for calling+data & 3G sim can be used for voice calling only on 3G/2G network. In circlelike Delhi(idea 3G 900mhz), Mumbai(Airtel 3G 900mhz), Kolkata(Airtel 3G 900mhz) 3G network on 900mhz is far superior than 2G network on same band due additional voice capacity and added high speed data advantage of 3G network.

Following chipsets support 4G+3G standby mode if phone implements the feature:

  • Qualcomm Snapdragon 617/625/650/820/821
  •  HiSilicon Kirin 960
  •  MediaTek X20/X23/X25/X27
  •  Samsung Exynos 8890

Adavantage of using 4G+3G phone is you’ll get better clarity on 3G network with call congestion. Your second sim will work in major countries with closing of 2G networks over the time around the world. disadvantage is your phone would drain battery faster as 3G network use it more.
