we shouldn't be surprised that 2G is getting shut down eventually. I'm surprised it's five years off yet.
Believe it or not, the process takes a lot of time.
First of all, you have to make sure all the sites are converted to 3G
/LTE technology. For the most part, each site can be converted quickly with very little issues. However, if expansion of the site is required, the zoning process can take time.
Once the site is converted, there is a testing period to make sure the coverage for the new technology is equal to or better than the existing 2G coverage.
After the sites are converted, then starts the long process of migrating customers with old 2G handsets to new 3G
or LTE devices. The company hopes most customers convert to newer handsets on their own. For many of the existing 2G customers, this will naturally place as old handsets breakdown from daily usage of the device.
Approximately one year prior to the shut down of the 2G network, the company will proactively contact the remaining 2G customers on a regular basis until most are on a 3G
There is always a small segment of the customer base that is caught off guard when the old technology gets turned off. This issue happened when the TDMA network was shut down several years ago.
