应该不太会，4g速度比3g快很多，
加上到时3g的频道会移到4g，所以4g频道会变大
对啊 国外都是关掉 3G 先 |

Taiwan
Taiwan's NCC urges 2G users to upgrade by June in 2017.
Australia
Telstra shut down their GSM network on 1 December 2016.
Optus will shut down their GSM network on 1 April 2017.
Vodafone announced its plans to decommission its legacy GSM network on 30 September 2017.
Canada
Rogers Wireless is the only provider offering a 2G network, until 2018.
Singapore
Singtel, M1, and StarHub will cease 2G services effective 1 April 2017.
Switzerland
Telecommunications in Switzerland is mainly operated by state-owned Swisscom, and the two privately held Salt and Sunrise Communications AG as these companies have a license to operate 2G.
Swisscom will cease 2G services due to its "public service requirements" only by 1 January 2021.
United States
Various carriers have made announcements that 2G technology in the United States is in the process of being shut down so that carriers can reclaim those radio bands and re-purpose them for newer technologies (e.g. 4G LTE). AT&T's 2G GSM service was shutdown in Jan-2017. This shutdown had a notable impact on the electronic security industry, where many 2G GSM radios were in use for alarm signal communication to Central Station dispatch centers. 2G GSM radios were required to be replaced by newer generation radios to avoid service outages. Verizon plans to shut down its 2G CDMA 1X network by 31 December 2019. Whereas, T-Mobile US has postponed shutdown of their 2G network until 2020.

 马来很难淘汰2g
2g用户还有很多
而且2g设备又特别长寿
我也是比较认同先干掉3g
但是实行起来很难

只有公司內部才有各個 network 用戶的數據
外人不知道到底 2G 和 3G 用戶的數量
就看誰比較激進敢先關掉其中一個
如果推 promotion 用舊機、折扣換新的 4G 機淘汰掉舊機
可以加快進化的腳步

最近去penang & langkawi
penang有4g，但是很慢
langkawi H+也是很慢，甚至一直断线
连我hometown H+也很慢了
最近的umobile是怎么了？
还是我有这些问题而已？

2g 不只是手机在用而已
我也不清楚为什么 M2M 会用到 2G
Telenor 这么说也有它的道理
...
真的我国2G和3G的用户太多了。
发展慢。
