You do not gain anything from using 4G for voice or SMS - 2G is overkill
PiTalk is a 3G phone http://pitalk.co.uk
that you can add your own programs into and the data rate is faster than some ADSL links in the local area
Thats a generalisation.
2G in a lot of countries has been decommissioned. A fact in Australia, and a lot of Asia.
For data, 4G with LTE has massive data capabilities. Depending on your carrier, 4G does offer advantages for SMS over 3G. Just check what your local carriers are providing, as you still have to use their SIM. NOt al lfeatures are supported by all carriers and plans.
With the push for 5G, a lot of 3G services will be replaced. 4G has at least a 10 year service window in most countries.
