2G is very old technology and so is 3G, 2G will stay as its used by IOT devices as part of LPWANs
3G from this June on some networks is starting to be turned off, so it is safe to assume o2 will turn it off in the next couple of years as well.

Well, it's all to do with holehinhthehwall machines, or ATMs, which extensively used the 2G network. 3G goes to free up wavebands for 5G. That's how I understand it, anyway. Guide: What is 2G, 3G, and 4G? may help.

2G is low bandwidth and High reach, and can run on limited power, as well as it is the base for all GSM Technologies, and even 4G runs on some of the 2G bands such as 1800mhz and 900mhz
3G is a power drain, and hence the new (Internet of Things) run on a LTE (4G) technology called LTE-M which is for low powered devices.
There is another reason, space on the masts is at a premium, and removing 3G radios will enable the networks to deploy 4G and 5G (and coming soon 6G in about 5years) radio and microwave links to provide better coverage.
@pgn has pointed to some excellent articles

And more on the topic of re-purposing frequencies here today, including the phrase "2G will be the last to go, as it still has some key uses":
