To date, an increasing number of providers (all of them actually) have stated that they will stop offering 3G, leading to major changes in mobile signal transmission. For users of newer smartphones who can also make calls via 4G (see this link), the impact will be minor; other groups will be particularly affected.
1. What does this mean for me?
In practice, most device users who were still using the 3G network will revert to 2G to make a call. These users may notice a slight deterioration in call quality. Fortunately, nowadays many phones are capable of using VoLTE (Voice over LTE), that is, calling over there 4G network. As a result, it is often still possible to get good call quality, even better than with 3G.
2. Minister expresses concern over accessibility of emergency numbers
However, there will always be a group using older devices that do not support 4G and therefore cannot use VoLTE technology for this reason. This could cause problems when 2G is also turned off at a later date. Micky Adriaansens, Dutch Minister of Economy and Climate, has already expressed concern that 112 should remain easily accessible.
3. The problem also affects automakers
In addition to being used for telephony, there are also cars using 2G and 3G. Practice will have to show how these devices will adapt to the networks being decommissioned. Since the lifespan of an automobile is sometimes longer than that of some networks, it is hoped that these network modules can be replaced to extend their lifespan.
